Are you rocky or are you gassy
Feb 09, 2018 (SPX)
The GJ 9827 star actually hosts a trio of planets, discovered by NASA's exoplanet-hunting Kepler/K2 mission, and all three are slightly larger than Earth. This ...
Viruses are falling from the sky
Feb 09, 2018 (SPX)

What the TRAPPIST-1 Planets Could Look Like
Feb 06, 2018 (SPX)
Of the known exoplanets (planets outside our solar system), TRAPPIST-1e is so far the one that is most similar to the Earth in terms of its size, density, and t...
TRAPPIST-1 Planets Probably Rich in Water
Feb 06, 2018 (SPX)
The hotter planets closest to their parent star are likely to have dense steamy atmospheres and the more distant ones probably have icy surfaces. In terms of si...
New Clues to Compositions of TRAPPIST-1 Planets
Feb 06, 2018 (JPL)
The form that water would take on TRAPPIST-1 planets would depend on the amount of heat they receive from their star, which is a mere 9 percent as massive as ou...
Hubble Delivers First Insight Into Atmospheres Of Potentially Habitable Planets Orbiting Trappist-1
Feb 06, 2018 (SPX)
Seven Earth-sized planets orbit the ultracool dwarf star TRAPPIST-1, 40 light-years away from the Earth. This makes TRAPPIST-1 the planetary system with the lar...
Astronomers identify first planets outside the Milk Way
Feb 05, 2018 (UPI)
Using telescopes at NASA's Chandra X-ray Observatory and an observation technique called microlensing, scientists at the University of Oklahoma discovered a pop...
Trappist planets have water, may be 'habitable': researchers
Feb 05, 2018 (AFP)
Though much remains unknown about the planets' surfaces and atmospheres, the new measurements have not ruled out the possibility that they may harbour even rudi...
Stellar embryos in dwarf galaxy contain complex organic molecules
Feb 01, 2018 (SPX)
New observations with the Atacama Large Millimeter/submillimeter Array (ALMA), however, have uncovered the surprisingly clear chemical "fingerprints" of the com...
A new 'atmospheric disequilibrium' could help detect life on other planets
Jan 29, 2018 (SPX)
The paper, published Jan. 24 in Science Advances, offers a new recipe for providing evidence that a distant planet harbors life. "This idea of looking for atmos...
A hot Jupiter with unusual winds
Jan 29, 2018 (SPX)
Unlike our familiar planet Jupiter, so-called hot Jupiters circle astonishingly close to their host star - so close that it typically takes fewer than three day...
NASA Poised to Topple a Planet-Finding Barrier
Jan 29, 2018 (SPX)
Babak Saif and Lee Feinberg at NASA's Goddard Space Flight Center in Greenbelt, Maryland, have shown for the first time that they can dynamically detect subatom...
