New Study Presents “Water World” Theory for the Emergence of Life

April 16, 2014

1 Comment

A new study describes how electrical energy naturally produced at the sea floor might have given rise to life, assembling decades of field, laboratory and theoretical research into a grand, unified picture. Life took root more than four billion years ago on our nascent Earth, a wetter and harsher place than now, bathed in sizzling […]

New Modeling Reveals that Tilted Orbits Could Make More Worlds Habitable

April 16, 2014

7 Comments

New research from astrobiologists at NASA’s Goddard Space Flight Center reveals that large amplitude, high frequency obliquity oscillations on Earth-like exoplanets can suppress the ice-albedo feedback, increasing the outer edge of the habitable zone. Pivoting planets that lean one way and then change orientation within a short geological time period might be surprisingly habitable, according […]

Researchers Discover the First Exomoon Candidate

April 11, 2014

0 Comments

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 […]

Using a spectral filter, NASA’s Cassini spacecraft views the lakes of Saturn’s moon Titan. The Cassini spacecraft peers down through layers of haze to glimpse the lakes of Titan’s northern regions. Titan (3,200 miles, or 5,150 kilometers across) has a hydrological cycle similar to Earth’s, but instead of water, Titan’s lakes and seas are filled […]

Curiosity Image Captures Mysterious Bright Spot

April 9, 2014

0 Comments

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 […]

Hubble Measures “El Gordo” Galaxy Cluster, Bigger Than Previously Thought

April 4, 2014

0 Comments

Researchers have measured the mass of the El Gordo Galaxy Cluster, calculating the cluster’s mass to be as much as 3 million billion times the mass of our sun. NASA’s Hubble Space Telescope has weighed the largest known galaxy cluster in the distant universe, cataloged as ACT-CL J0102-4915, and found it definitely lives up to […]

Fermi Data Reveal New Clues to Dark Matter

April 4, 2014

1 Comment

New maps from the Fermi-LAT Collaboration show that the galactic center produces more high-energy gamma rays than can be explained by known sources, suggesting that this excess emission is consistent with some forms of dark matter. A new study of gamma-ray light from the center of our galaxy makes the strongest case to date that […]

NASA Detects Ocean Inside Saturn’s Moon Enceladus

April 4, 2014

0 Comments

New data from NASA’s Cassini spacecraft and Deep Space Network provide the first geophysical measurements of the internal structure of Enceladus, suggesting that it harbors a large interior ocean beneath an ice shell. NASA’s Cassini spacecraft and Deep Space Network have uncovered evidence Saturn’s moon Enceladus harbors a large underground ocean of liquid water, furthering […]

New SDO Image of X-Class Solar Flare

April 1, 2014

0 Comments

This new image of an X-class solar flare was captured by NASA’s Solar Dynamics Observatory on March 29, 2014. The sun emitted a significant solar flare, peaking at 1:48 p.m. EDT March 29, 2014, and NASA’s Solar Dynamics Observatory captured images of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a […]
