Deep Sea Shrimp May Hold Clues to Alien Life

Scientists at NASA’s Jet Propulsion Laboratory reveal that the extreme oasis of life deep in the Caribbean Sea may hold clues to life on other planetary bodies, including Jupiter’s moon Europa. At one of the world’s deepest undersea hydrothermal vents, tiny shrimp are piled on top of each other, layer upon layer, crawling on rock […]

Red Spot on Jupiter is Likely a Sunburn

New data from NASA’s Cassini mission reveal that the color of Jupiter’s Great Red Spot is likely a product of simple chemicals being broken apart by sunlight in the planet’s upper atmosphere, contradicting the other leading theory for the origin of the spot’s striking color — that the reddish chemicals come from beneath Jupiter’s clouds. […]

CAL Cools Atoms to Ultracold Temperatures

Researchers will use NASA’s Cold Atom Laboratory to study ultra-cold quantum gases, exploring how atoms interact in microgravity when they have almost no motion due to such cold temperatures. Like dancers in a chorus line, atoms’ movements become synchronized when lowered to extremely cold temperatures. To study this bizarre phenomenon, called a Bose-Einstein condensate, researchers […]

New Detailed Image of 67P Churyumov Gerasimenko

Taken by ESA’s Rosetta Spacecraft, this new image of comet 67P/Churyumov-Gerasimenko shows the diversity of surface structures on the comet’s nucleus. The image was taken by the Rosetta spacecraft’s OSIRIS narrow-angle camera on August 7, 2014. At the time, the spacecraft was 65 miles (104 kilometers) away from the 2.5-mile-wide (4-kilometer) nucleus. In the image, […]

NASA Discovers Further Evidence of Dry Ice Gullies on Mars

A new study details further evidence of dry ice gullies on Mars, revealing that the gullies on Mars’ surface are primarily formed by the seasonal freezing of carbon dioxide, not liquid water. Repeated high-resolution observations made by NASA’s Mars Reconnaissance Orbiter (MRO) indicate the gullies on Mars’ surface are primarily formed by the seasonal freezing […]

Radar Observations of Asteroid 2014 HQ124

Using the Deep Space Network antenna and two other radio telescopes, astronomers were able to capture radar observations of asteroid 2014 HQ124 as it passed Earth on June 8, 2014. NASA scientists using Earth-based radar have produced sharp views of a recently discovered asteroid as it slid silently past our planet. Captured on June 8, […]

Curiosity Rover Views Mercury Passing in Front of the Sun

This new animated image from NASA’s Curiosity rover shows Mercury passing in front of the Sun. NASA’s Curiosity Mars rover has imaged the planet Mercury passing in front of the sun, visible as a faint darkening that moves across the face of the sun. This is the first transit of the sun by a planet […]

Spitzer Space Telescope Reveals a Rare Example of Type Ia Explosion

Using data from NASA’s Spitzer Space Telescope, astronomers examined a rare example of Type Ia explosion in which a dead star “fed” off an aging star. Supernovas are often thought of as the tremendous explosions that mark the ends of massive stars’ lives. While this is true, not all supernovas occur in this fashion. A […]

Cassini Views Uranus for the First Time

On April 11, 2014 NASA’s Cassini spacecraft took its first-ever image of the planet Uranus, shown in the distance beyond Saturn’s rings. The robotic spacecraft briefly turned its gaze away from the ringed beauty of Saturn on April 11, 2014, to observe the distant planet, which is the seventh planet from the sun. The planets […]

Scientists Believe Ganymede Has a Massive Ocean Under an Icy Crust

New research based on laboratory experiments shows that Jupiter’s moon Ganymede may have oceans and ice stacked up in multiple layers like a club sandwich. The largest moon in our solar system, a companion to Jupiter named Ganymede, might have ice and oceans stacked up in several layers like a club sandwich, according to new […]

Spitzer and WISE Find Cold Neighbor of Sun

NASA’s WISE and Spitzer Space Telescope have discovered the coldest known brown dwarf, which is located 7.2 light-years away. NASA’s Wide-field Infrared Survey Explorer (WISE) and Spitzer Space Telescope have discovered what appears to be the coldest “brown dwarf” known — a dim, star-like body that surprisingly is as frosty as Earth’s North Pole. Images […]

Researchers Discover the First Exomoon Candidate

By using gravitational microlensing and taking advantage of chance alignments between stars, an international team of researchers has spotted the first signs of an exomoon. Titan, Europa, Io and Phobos are just a few members of our solar system’s pantheon of moons. Are there are other moons out there, orbiting planets beyond our sun? NASA-funded […]

Curiosity Sees Mysterious Bright Spot

A newly released Curiosity image shows a bright spot on the surface of Mars, which was possibly caused by the sun glinting off a rock or cosmic rays striking the camera’s detector. Images taken by NASA’s Curiosity Mars rover on April 2 and April 3 include bright spots, which might be due to the sun […]
