Using 10 years of ultraviolet observations by NASA’s Galaxy Evolution Explorer (GALEX) Spacecraft, astronomers examine the habitability of planets near red dwarfs. Cool dwarf stars…
Using the Hubble Space Telescope astronomers compare two seemingly similar “hot Jupiter” exoplanets, finding that WASP-67 b and HAT-P-38 b have very different atmospheres. Is…
NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) mission has released its third year of survey data, with the spacecraft discovering 97 previously unknown celestial…
An international team of astronomers has discovered a planet like Jupiter zipping around its host star every day, boiling at temperatures hotter than most stars…
NASA’s Dawn Spacecraft captured this image of the Kerwan crater (the largest crater on Ceres) from an altitude of about 915 miles. The 16-mile-wide (26-kilometer-wide)…
This Hubble Telescope image of the week shows the slow waltz of two brown dwarfs in Luhman 16AB. This seemingly unspectacular series of dots with…
Using data from NASA’s Curiosity Rover, new research reveals that a long-lasting lake on ancient Mars provided stable environmental conditions that differed significantly from one…
New research from the Harvard-Smithsonian Center for Astrophysics reveals that the correlation between a galaxy’s stellar mass and star formation rate is a tight one….
The Laser Interferometer Gravitational-wave Observatory (LIGO) has made a third detection of gravitational waves, ripples in space and time, demonstrating that a new window in…
By comparing theoretical models to Chandra surveys and the Sloan Digital Sky Survey, astronomers have found evidence that the very earliest supermassive black holes in…
An international team of astronomers show that a giant gas planet – up to 50x the mass of Jupiter, encircled by a ring of dust…
NASA’s Lunar Reconnaissance Orbiter (LRO) has identified bright areas in craters near our moon’s south pole that are cold enough to have frost present on…
New data from NASA’s Cassini Spacecraft reveals evidence that the active south polar region of Enceladus — the fractured terrain seen here at bottom —…
NASA’s Cassini Spacecraft captures a close-up view of the Keeler Gap. Before Cassini entered its Grand Finale orbits, it acquired unprecedented views of the outer…
A team of astronomers has put a basic principle of black holes to the test, showing that matter completely vanishes when pulled in. Their results…
This Hubble image of the week shows the Vermin Galaxy as it began its transit behind star HD 107146. The galaxy will not be fully…
A team of astronomers has discovered a new kind of galaxy in the early universe, less than a billion years after the Big Bang. These…
A new NASA mission is headed for the International Space Station next month to observe one of the strangest observable objects in the universe. The…
