Cassini Flyby Shows Enceladus Venting Credit: NASA/JPL/SSI; Mosaic: Emily Lakdawalla Explanation: What's happening on the surface of Saturn's moon Enceladus? Enormous ice jets are erupting. Giant plumes of ice have been photographed in dramatic fashion by the robotic Cassini spacecraft during this past weekend's flyby of Saturn's moon Enceladus. Pictured above, numerous plumes are seen rising from long tiger-stripe canyons across Enceladus' craggy surface. Several ice jets are even visible in the shadowed region of crescent Enceladus as they reach high enough to scatter sunlight. Other plumes, near the top of the above image, appear visible just over the moon's sunlit edge. That Enceladus vents fountains of ice was first discovered on Cassini images in 2005, and has been under close study ever since. Continued study of the ice plumes may yield further clues as to whether underground oceans, candidates for containing life, exist on this distant ice world.

Nembrotha kubaryana - nembrotha-kubaryana-615.jpg

Nudibranch. Latin for nudis (naked). Greek for brankhia (gills). The name is accurate because they breathe with organs on their backs that act as external gills. Essentially, they are aquatic snails without a shell. They are poisonous, armed with stinging cells and toxic secretions. Most announce their poisonous capabilities with their strong colors. Some make their own poison, but some take them from the animals they eat. Yeah, they are carnivores. So, they slime across the ocean floor to find food; if they eat a poisonous sponge, they store the poison and excrete it from their skin. They'll even eat other nudibranchs. These bad boys/girls cannibals are found at all depths of the ocean. I say boys/girl because nudibranchs are hermaphroditic, so they have male and female reproductive organs. (They rarely impregnate themselves.) They vary in size from 1 to 24 inches (2 to 60cm) in length. There are over 3,000 species of these guys/girls.

Ares 1-X Rocket Lifts Off Credit & Copyright: Rory A. Duncan (United Space Alliance) Explanation: Last week, NASA test fired a new rocket. The Ares 1-X was the first non-shuttle rocket launched from Kennedy Space Center since the Saturn launched humans to Earth orbit and the Moon in the 1960s and 1970s. NASA is testing Ares as a prelude to replacing the aging space shuttle fleet. The tremendous thrust of the Ares 1-X can bring the massive rocket from a standing start to a vertical speed of over 100 kilometers per hour in under eight seconds. The test rocket launched last week was longer than a football field and covered with over 700 sensors to record data that will enable engineers to refine details of future Ares rockets. Pictured above, the Ares 1-X blasts into space while the top part of the rocket becomes engulfed in a shock collar of water droplets likely created by the sudden drop of air pressure.

Blue Sun Bristling - bluesun_friedman.jpg

Credit & Copyright: Alan Friedman (Averted Imagination) Explanation: Our Sun may look like all soft and fluffy, but it's not. Our Sun is an extremely large ball of bubbling hot gas, mostly hydrogen gas. The above picture of our Sun was taken last month in a specific red color of light emitted by hydrogen gas called Hydrogen-alpha and then color inverted to appear blue. In this light, details of the Sun's chromosphere are particularly visible, highlighting numerous thin tubes of magnetically-confined hot gas known as spicules rising from the Sun like bristles from a shag carpet. Our Sun glows because it is hot, but it is not on fire. Fire is the rapid acquisition of oxygen, and there is very little oxygen on the Sun. The energy source of our Sun is the nuclear fusion of hydrogen into helium deep within its core. No sunspots or large active regions were visible on the Sun this day, although some solar prominences are visible around the edges.

Stickney Crater

Stickney Crater - PSP_007769_9010_IRB_Stickney800.jpg

Stickney Crater Credit: HiRISE, MRO, LPL (U. Arizona), NASA Explanation: Stickney Crater, the largest crater on the martian moon Phobos, is named for Chloe Angeline Stickney Hall, mathematician and wife of astronomer Asaph Hall. Asaph Hall discovered both the Red Planet's moons in 1877. Over 9 kilometers across, Stickney is nearly half the diameter of Phobos itself, so large that the impact that blasted out the crater likely came close to shattering the tiny moon. This stunning, enhanced-color image of Stickney and surroundings was recorded by the HiRISE camera onboard the Mars Reconnaissance Orbiter as it passed within some six thousand kilometers of Phobos in March of 2008. Even though the surface gravity of asteroid-like Phobos is less than 1/1000th Earth's gravity, streaks suggest loose material has slid down inside the crater walls over time. Light bluish regions near the crater's rim could indicate a relatively freshly exposed surface. The origin of the curious grooves along the surface is mysterious but may be related to the crater-forming impact.

Nereus Crater on Mars Credit: Mars Exploration Rover Mission, JPL, NASA; Image Processing: Kenneth Kremer Explanation: It was along the way. The robotic rover Opportunity currently rolling across the Meridiani Plain on Mars has a destination of Endeavour Crater, a large crater over 20 kilometers across which may yield additional clues about the cryptic past of ancient Mars. Besides passing open fields of dark soil and light rock, Opportunity has chanced upon several interesting features. One such feature, pictured above in a digitally stitched and horizontally compressed panorama, is Nereus Crater, a small crater about 10 meters across that is surrounded by jagged rock. Besides Nereus, Opportunity recently also happened upon another unusual rock -- one that appears to be the third large meteorite found on Mars and the second for Opportunity during only this trip. Opportunity has been traveling toward Endeavour Crater for over a year now, and if it can avoid ridged rocks and soft sand along the way, it may reach Endeavour sometime next year.

Meteor Explodes Over the Netherlands

Meteor Explodes Over the Netherlands - 091015-fireball-explodes-netherland.jpg

When amateur photographer Robert Mikaelyan went out to snap an old Dutch sugar factory on Tuesday, he captured a rare treat: a huge exploding fireball in the sky. Hundreds of people in the Netherlands and Germany reported seeing the fireball streak across the twilight skies around 7 p.m. local time on October 13. Mikaelyan managed to capture several shots of the fireball as it swung low over the northern city of Groningen and began to break apart into smaller chunks. "I suddenly saw a light in the sky coming fast … and quickly got the pictures taken," Mikaelyan said via email. A few seconds after the fireball had been sighted, witnesses heard a sonic boom followed by low rumbles that rattled windows—signatures of a high-altitude explosion. (Related: "Giant Meteor Fireball Explodes Over Northwest U.S.") The object was most likely a rogue space rock that disintegrated shortly after hitting Earth's atmosphere, say experts, who speculate that pieces of the meteor may have landed in the North Sea (see map). "Indeed it was a huge event," said Theo Jurriens, of the Kapteyn Astronomical Institute at the University of Groningen. Earth is constantly being bombarded by smaller debris from comets, asteroids, and even other rocky planets in the solar system. But a fireball of this size and brightness is likely seen anywhere in the world only every 20 to 25 years, Jurriens estimates. For photographer Mikaelyan, "it was a very special thing to see, especially the light and the speed." —Victoria Jaggard Photograph by Robert Mikaelyan

Giant Sea "Mucus" Blobs

Giant Sea "Mucus" Blobs - 091008-01-giant-sea-mucus-blobs_big.jpg

Marine biologist Serena Fonda Umani approaches a blob of dead and living organic matter, called a mucilage, in the Adriatic Sea, an arm of the Mediterranean, in 1991 (Adriatic Sea map). Umani, of Italy's University of Trieste, remembers diving about 50 feet (15 meters) down when she got the sensation of a ghost floating over her--"sort of an alien experience." Enormous sheets of such "mucus" occur naturally throughout the Mediterranean, especially in the Adriatic. But in recent years, as sea temperatures have risen, these sea congregations are exploding in number and size--sometimes stretching over hundreds of kilometers, generally near coastlines, according to a study published in September 2009 in the journal PLoS One. More than just unpleasant, the blobs harbor bacteria and viruses, including E. coli, that can be harmful to swimmers, the study said.

The Great Basin on Saturn's Tethys Credit: Cassini Imaging Team, SSI, JPL, ESA, NASA Explanation: Some moons wouldn't survive the collision. Tethys, one of Saturn's larger moons at about 1000 kilometers in diameter, survived the collision, but sports today the expansive impact crater Odysseus. Sometimes called the Great Basin, Odysseus occurs on the leading hemisphere of Tethys and shows its great age by the relative amount of smaller craters that occur inside its towering walls. Another large crater, Melanthius, is visible near the moon's terminator. The density of Tethys is similar to water-ice. The above digitally enhanced image was captured in July by the robot Cassini spacecraft in orbit around Saturn as it swooped past the giant ice ball.

glowing mushrooms - 091005-06-glowing-mushroom-chloroph.jpg

Photograph courtesy Eiji Nagasawa, Tottori Mycological Institute, Japan Glowing nonstop in the Brazilian rain forest, the newfound mushroom Mycena luxaeterna (pictured both in daylight, top, and in the dark) is indeed a source of eternal light (at least at night), as its Latin name—inspired by verses from Mozart's "Requiem"—implies. The tiny mushroom is one of 7 new species of glow-in-the-dark fungi found around the world, bringing the total known to 71, according to a study that appeared October 5 in the journal Mycologia. San Francisco State University's Dennis Desjardin and colleagues scouted for mushrooms during new moons, in rain forests so dark they often couldn't see their hands in front of their faces, he said. But "when you look down at the ground, it's like looking up at the sky," Desjardin said. "Every little 'star' was a little mushroom—it was just fantastic." M. luxaeterna has a distinctive sticky gel on its stem that probably keeps it moist during the heat of the day. Unwitting insects get trapped in this natural fly paper, said Desjardin, who discovered the fungi with the University of Sao Paulo's Cassius V. Stevani.

water discovered on earth - moonwater_isro.jpg

Water Discovered on the Moon Credit: ISRO/NASA/JPL-Caltech/USGS/Brown U. Explanation: Water has been discovered on the surface of the Moon. No lakes have been found, but rather NASA's Moon Mineralogy Mapper aboard India's new Chandrayaan-1 lunar orbiter radios back that parts of the Moon's surface absorb a very specific color of light identified previously only with water. Currently, scientists are trying to fit this with other facts about the Moon to figure out how much water is there, and even what form this water takes. Unfortunately, even the dampest scenarios leave our moon dryer than the driest of Earth's deserts. A fascinating clue being debated is whether the water signal rises and falls during a single lunar day. If true, the signal might be explainable by hydrogen flowing out from the Sun and interacting with oxygen in the lunar soil. This could leave an extremely thin monolayer of water, perhaps only a few molecules thick. Some of the resulting water might subsequently evaporate away in bright sunlight. Pictured above, the area near a crater on the far side of the Moon shows a relatively high abundance of water-carrying minerals in false-color blue. Next week, the new LCROSS satellite will release an impactor that will strike a permanently shadowed crater near the lunar south pole to see if any hidden water or ice sprays free there.

To Fly Free in Space - freeflyer_nasa.jpg

To Fly Free in Space Credit: STS-41B, NASA Explanation: At about 100 meters from the cargo bay of the space shuttle Challenger, Bruce McCandless II was farther out than anyone had ever been before. Guided by a Manned Maneuvering Unit (MMU), astronaut McCandless, pictured above, was floating free in space. McCandless and fellow NASA astronaut Robert Stewart were the first to experience such an "untethered space walk" during Space Shuttle mission 41-B in 1984. The MMU works by shooting jets of nitrogen and has since been used to help deploy and retrieve satellites. With a mass over 140 kilograms, an MMU is heavy on Earth, but, like everything, is weightless when drifting in orbit. The MMU was replaced with the SAFER backpack propulsion unit.

Salmonella typhimurium in Microgravity - 7salmonellaweb.jpg

Weightlessness may be doubly dangerous for fending off infection. Space travel seems to weaken the immune system, and it may also make a range of microbes deadlier than they are on Earth. A flight of the space shuttle Atlantis in 2006 showed that the bacterium Salmonella typhimurium (shown here in red) was nearly three times as likely to kill mice. Microgravity also seems to boost the virulence of methicillin-resistant Staphylococcus aureus, an antibiotic-resistant superbug that is a common cause of infection in hospitals. A firm called Astrogenetix is now studying this increased potency to isolate factors responsible for virulence in the hopes of producing vaccines. (Image: NASA)

microgravity - 1surftensionweb.jpg

In the absence of gravity, surface tension dominates the physics of fluids. Here, in an image taken on the International Space Station, it causes water to extend from a metal loop as if it were stirred by an invisible spoon. This stirring effect was created by using a flashlight to unevenly heat the water. The resulting temperature difference induced an imbalance in the surface tension, causing the fluid to rotate. Such surface-tension-triggered movement, called Marangoni convection, is less obvious on Earth, but can be seen in environments such as cooling puddles of molten steel. (Image: NASA)

These ominous figures are actually molecular clouds, knots of molecular gas and dust so thick they have become opaque. In comparison, however, these clouds are typically much less dense than Earth's atmosphere. Pictured above is part of the most detailed image of the Carina Nebula ever taken, a part where dark molecular clouds are particularly prominent. The entire Carina Nebula spans over 300 light years and lies about 7,500 light-years away in the constellation of Carina. NGC 3372, known as the Great Nebula in Carina, is home to massive stars and changing nebula. Eta Carinae, the most energetic star in the nebula, was one of the brightest stars in the sky in the 1830s, but then faded dramatically.

Ganymede Enhanced - ganymedeenhanced_galileo.jpg

Ganymede Enhanced Credit: Galileo Project, DLR, JPL, NASA Explanation: What does the largest moon in the Solar System look like? Ganymede, larger than even Mercury and Pluto, has a surface speckled with bright young craters overlying a mixture of older, darker, more cratered terrain laced with grooves and ridges. Like Earth's Moon, Ganymede keeps the same face towards its central planet, in this case Jupiter. In this historic and detailed image mosaic taken by the Galileo spacecraft that orbited Jupiter from 1995 to 2003, the colors of this planet-sized moon have been enhanced to increase surface contrasts. The violet shades extending from the top and bottom are likely due to frost particles in Ganymede's polar regions. Possible future missions to Jupiter are being proposed that can search Europa and Ganymede for deep oceans that may harbor elements thought important for supporting life.

Eye of a Tokay Gecko - macro_photo_1.jpg

The Tokay Gecko (Gekko gecko) is a nocturnal arboreal gecko, ranging from northeast India and Bangladesh, throughout Southeast Asia, to Indonesia and western New Guinea. Its native habitat is rainforest trees and cliffs, and it also frequently adapts to rural human habitations, roaming walls and ceilings at night in search of insect prey. Increasing urbanization is reducing its range. In the late 1980's and early 1990's it was introduced into Hawaii, Florida, Texas, Belize, and several Caribbean islands, where it can be considered an invasive species. The Tokay Gecko is also the inspiration of the fictional

The Crescent Nebula - NGC6888_Lopez900.jpg

NGC 6888: The Crescent Nebula Credit & Copyright: Daniel López, IAC Explanation: NGC 6888, also known as the Crescent Nebula, is a cosmic bubble about 25 light-years across, blown by winds from its central, bright, massive star. This beautiful portrait of the nebula is from the Isaac Newton Telescope at Roque de los Muchachos Observatory in the Canary Islands. It combines a composite color image with narrow band data that isolates light from hydrogen and oxygen atoms in the wind-blown nebula. The oxygen atoms produce the blue-green hue that seems to enshroud the detailed folds and filaments. NGC 6888's central star is classified as a Wolf-Rayet star (WR 136). The star is shedding its outer envelope in a strong stellar wind, ejecting the equivalent of the Sun's mass every 10,000 years. The nebula's complex structures are likely the result of this strong wind interacting with material ejected in an earlier phase. Burning fuel at a prodigious rate and near the end of its stellar life this star should ultimately go out with a bang in a spectacular supernova explosion. Found in the nebula rich constellation Cygnus, NGC 6888 is about 5,000 light-years away.

bacteriophages - phages_wikipedia.jpg

Bacteriophages: The Most Common Life-Like Form on Earth Credit: Wikipedia; Insert: Mike Jones Explanation: There are more bacteriophages on Earth than any other life-like form. These small viruses are not clearly a form of life, since when not attached to bacteria they are completely dormant. Bacteriophages attack and eat bacteria and have likely been doing so for over 3 billion years ago. Although initially discovered early last century, the tremendous abundance of phages was realized more recently when it was found that a single drop of common seawater typically contains millions of them. Extrapolating, phages are likely to be at least a billion billion (sic) times more numerous than humans. Pictured above is an electron micrograph of over a dozen bacteriophages attached to a single bacterium. Phages are very small -- it would take about a million of them laid end-to-end to span even one millimeter. The ability to kill bacteria makes phages a potential ally against bacteria that cause human disease, although bacteriophages are not yet well enough understood to be in wide spread medical use.

Morning Glory Clouds Over Australia Credit & Licence: Mick Petroff; Tip Thanks: James Holmes (Cairns) Explanation: What causes these long, strange clouds? No one is sure. A rare type of cloud known as a Morning Glory cloud can stretch 1,000 kilometers long and occur at altitudes up to two kilometers high. Although similar roll clouds have been seen at specific places across the world, the ones over Burketown, Queensland Australia occur predictably every spring. Long, horizontal, circulating tubes of air might form when flowing, moist, cooling air encounters an inversion layer, an atmospheric layer where air temperature atypically increases with height. These tubes and surrounding air could cause dangerous turbulence for airplanes when clear. Morning Glory clouds can reportedly achieve an airspeed of 60 kilometers per hour over a surface with little discernible wind. Pictured above, photographer Mick Petroff photographed some Morning Glory clouds from his airplane near the Gulf of Carpentaria, Australia.

Supernova Remnant E0102-72 Credit: X-ray - NASA / CXC / MIT / D.Dewey et al., NASA / CXC / SAO / J.DePasquale; Optical - NASA / STScI Explanation: The expanding debris cloud from the explosion of a massive star is captured in this multiwavelength composite, combining x-ray and optical images from the Chandra and Hubble telescopes. Identified as E0102-72, the supernova remnant lies about 190,000 light-years away in our neighboring galaxy, the Small Magellanic Cloud. A strong cosmic source of x-rays, E0102 was imaged by the Chandra X-ray Observatory shortly after its launch in 1999. In celebration of Chandra's 10th anniversary, this colorful view of E0102 and its environs was created, including additional Chandra data. An analysis of all the data indicates that the overall shape of E0102 is most likely a cylinder that is viewed end-on rather than a spherical bubble. The intriguing result implies that the massive star's explosion has produced a shape similar to what is seen in some planetary nebulae associated with lower mass stars. At the distance of the Small Magellanic Cloud, this field of view spans about 150 light-years.

Galactic "Jellyfish" - 080820-galaxy-photo_big.jpg

August 20, 2008—Bubbles that burst deep in the heart of the galaxy NGC 1275, seen above, created tentacles of cold gas that have mysteriously lingered in the surrounding heat for up to a hundred million years. Now a team of international researchers thinks it knows why this cosmic "jellyfish" hasn't lost its sting. Andrew Fabian at the U.K.'s University of Cambridge and colleagues analyzed images of the streamers captured by the Hubble Space Telescope and proposed that the galaxy's large but delicate filaments are held together by magnetic fields. When the supermassive black hole at the center of NGC 1275 blasts bubbles of cold gases into space, it forms filaments that can be up to 20,000 light-years long and 280 light-years across. Such ribbons should dissipate into the surrounding hot gases, which are about 70 million degrees Fahrenheit (40 million degrees Celsius). But in a new paper in this week's issue of the journal Nature, Fabian and colleagues suggest that when the filaments shoot outward, they take some of the galaxy's magnetic field with them. Although the strength of the filaments' fields is low—about one ten-thousandth the strength of Earth's magnetic field—it's enough to help them hang together. "The pressure of that magnetic field is comparable to the pressure of the hot gas surrounding it," Fabian said. The field stops the filaments from collapsing under their own gravity and stops hot gas from evaporating the cold streamers. Further understanding of how the streamers stay together could provide a model for studying other distant young galaxies, which often appear to be surrounded by such filaments, Fabian added. —Anne Minard

Still, the Moon's silhouette was highlighted by these glistening diamonds as the total eclipse phase ended. Caused by bright sunlight streaming through dips and valleys in the irregular terrain along the Moon's edge, the effect is known as Baily's Beads, named after Francis Baily who called attention to the phenomenon in 1836. The dramatic appearance of the beads at the beginning or end of a total solar eclipse is also known as the Diamond Ring effect. In this remarkable image, a small, pinkish solar prominence can also be seen along the edge, below the diamonds.

Saturn's Iapetus: Painted Moon

Saturn's Iapetus: Painted Moon - iapetus3_cassini.jpg

Credit: Cassini Imaging Team, SSI, JPL, ESA, NASA Explanation: What has happened to Saturn's moon Iapetus? Vast sections of this strange world are dark as coal, while others are as bright as ice. The composition of the dark material is unknown, but infrared spectra indicate that it possibly contains some dark form of carbon. Iapetus also has an unusual equatorial ridge that makes it appear like a walnut. To help better understand this seemingly painted moon, NASA directed the robotic Cassini spacecraft orbiting Saturn to swoop within 2,000 kilometers in 2007. Pictured above, from about 75,000 kilometers out, Cassini's trajectory allowed unprecedented imaging of the hemisphere of Iapetus that is always trailing. A huge impact crater seen in the south spans a tremendous 450 kilometers and appears superposed on an older crater of similar size. The dark material is seen increasingly coating the easternmost part of Iapetus, darkening craters and highlands alike. Close inspection indicates that the dark coating typically faces the moon's equator and is less than a meter thick. A leading hypothesis is that the dark material is mostly dirt leftover when relatively warm but dirty ice sublimates. An initial coating of dark material may have been effectively painted on by the accretion of meteor-liberated debris from other moons. This and other images from Cassini's Iapetus flyby are being studied for even greater clues.

The Telepathic Bot Known for: Reading minds Honda's ASIMO humanoid robot can now be controlled with thought alone—and with a little help from brain machine interface technology. BMI tech relies on electroencephalography (EEG) and near-infrared spectroscopy (NIRS) and newly developed information abstraction technology. How it works: EEG and NIRS sensors are placed on a person's head. When the user imagines moving one of four predetermined body part options, ASIMO complies with a corresponding movement. The setup detects changes in brain waves and cerebral blood flow, which is analyzed on a real-time basis to translate what the user imagined. Tests on the process yielded a 90 percent accuracy rate, says Honda. credit - honda

The Fish Bot Known for: Fighting pollution A school of robotic carp—equipped with chemical sensors and artificial intelligence—will be unleashed into a Spanish port to search for water pollutants. Developed by British scientists, these five-foot-long robotic fish will monitor oxygen levels and detect potentially hazardous leaks. The fish will communicate with each other using ultrasonics, and information will be wirelessly sent to the "charging hub" (where fish will charge their batteries). The port's authorities can use this data to track the source and scale of the pollution. If this robotic pollution monitoring system is successful, researchers hope to use it globally. image credit - bmt group

SN 1006 Supernova Remnant - sn1006c_c800.jpg

Image Credit: NASA, ESA, Zolt Levay (STScI) Explanation: A new star, likely the brightest supernova in recorded human history, lit up planet Earth's sky in the year 1006 AD. The expanding debris cloud from the stellar explosion, found in the southerly constellation of Lupus, still puts on a cosmic light show across the electromagnetic spectrum. In fact, this composite view includes X-ray data in blue from the Chandra Observatory, optical data in yellowish hues, and radio image data in red. Now known as the SN 1006 supernova remnant, the debris cloud appears to be about 60 light-years across and is understood to represent the remains of a white dwarf star. Part of a binary star system, the compact white dwarf gradually captured material from its companion star. The buildup in mass finally triggered a thermonuclear explosion that destroyed the dwarf star. Because the distance to the supernova remnant is about 7,000 light-years, that explosion actually happened 7,000 years before the light reached Earth in 1006. Shockwaves in the remnant accelerate particles to extreme energies and are thought to be a source of the mysterious cosmic rays.

gravity lumps - grace.jpg

Gravity lumps It's a face we all know, but the portrait is entirely new. The colors in this piece of art represent Earth's gravitational field. Of course, no matter where on Earth your feet are planted, gravity buckles them to the ground. But what you might not know -- or even notice -- is that gravity is nuanced. In some places (shown in red), it is stronger than in others (blue). To measure this variation, a NASA spacecraft trailed another as it zipped around the Earth and through its gravitational field. By measuring subtle changes in the distance between the two spacecrafts, the US-German Gravity Recovery and Climate Experiment (Grace) crafted this map of gravity?s pull. Some hotspots are obvious, such as the Himalayan Mountains that stretch along the border between India and Tibet. But in the oceans, mass shifts constantly and massive formations aren?t so obvious. For this reason, the Grace maps provide scientists a valuable view of the underwater landscape. These shades of gravity will help scientists predict changes in the climate and understand how oceans move. Courtesy NASA
