New Study Reassesses Habitability of Exoplanets Around Multiple Star Systems

An artist’s concept of Kepler-47, which was the first-ever planetary system to be discovered orbiting a binary star. A new research that was based on data taken with NASA’s Hubble Space Telescope provides stringest limits to the potential habitablity of exoplanets in several such systems.

Cloudy With a Chance of Sunshine: Astronomers Study Weather on Distant Exoplanets

An artist’s rendering of the possible weather and atmospheric circulation patterns on hot Jupiters. A new research by a team of astronomers that was based on data taken with NASA’s Kepler space telescope, studied the phase variations that occur as different portions of these planets are illuminated by their host stars as seen from […]

'Ocean Worlds Exploration Program': New Budget Proposal Calls for Missions to Europa, Enceladus and Titan

The exploration of the outer Solar System has revealed a plethora of amazing worlds, the likes of which […]

Researchers Develop New Technique to Search for Chemical Evidence of Life on Mars

Despite decades of searching, definitive evidence for life on Mars, past or present, has still remained elusive and controversial. Confirmation of such a finding would need to be thoroughly tested and documented, and now researchers at the University of Kansas have developed a new technique that they hope would help to do just that, […]

New Horizons Mission Returns First Images of Pluto's Smallest Known Moons Kerberos and Styx

NASA’s New Horizons spacecraft has just returned the first long-range images of Kerberos and Styx, the two smallest moons of Pluto. Each animation consists of five 10-second frames which were taken with the onboard LORRI camera between April 25 and May 1At left is the initial set of raw images, while at the center […]

With so much attention now on the rovers and spacecraft at Mars, Saturn, Ceres, comet 67P/Churyumov-Gerasimenko, and, soon, Pluto, it may seem like Earth’s closest planetary neighbor Venus has been forgotten again. But no, […]

Building Blocks of DNA Can Potentially Be Created in Space, According to New Study

An artist’s impression of the material that has been ejected from the Supernova 1987A in the neighboring Large Magellanic Cloud. The violent deaths of stars during supernova exoplosions, expel most of the stellar material into interstellar space, reseeding it with large amounts of dust as well as complex organic compounds which form the basis […]

Dark Material in Fractures on Europa's Surface Is Sea Salt, New Research Suggests

For over a decade, scientists have been curious about the long fractures on Europa’s icy surface and the darker-colored material they contain, as well as other relatively young geological […]

Event Horizon Telescope Provides New Evidence for Existence of Black Holes
