Distant planet's atmosphere shows evidence of water vapor
Sep 24, 2014 (UPI)
A Neptune-sized exoplanet, which lies some 729 trillion miles away (122 light-years), has water vapor in its atmosphere. While it's a promising sign for astrono...
Chandra Finds Planet That Makes Star Act Deceptively Old
Sep 17, 2014 (SPX)
A planet may be causing the star it orbits to act much older than it actually is, according to new data from NASA's Chandra X-ray Observatory. This discovery sh...
Solar System Simulation Reveals Planetary Mystery
Sep 15, 2014 (NASA)
