Detection of extrasolar planets
Life and Death of a Planetary System. New results from the th American Astronomical Society meeting reveal that Earth-sized planets can be made of minerals that are distinctly not Earth-like. With new NASA apps, you can take a selfie in space or tour a system of alien planets. The ASTERIA satellite, currently in low-Earth orbit, is only slightly larger than a box of cereal, but it could help astrophysicists study planets orbiting other stars.
Astrophysics CubeSat demonstrates big potential in a small package. Scientists used NASA's Hubble and Spitzer space telescopes to find water "fingerprints" in the atmosphere of a hot, bloated, Saturn-mass exoplanet some light-years away. NASA finds a large amount of water in an exoplanet's atmosphere. Role models, footsteps, and the search for life.
New planet is largest discovered that orbits two suns. A discovery one-ups Tatooine by finding twin stars which host three giant exoplanets. Three giant worlds found orbiting twin suns. NASA's efforts in digital communications have been recognized with nominations for six Webby Awards, the highest honor for online communications. Our nearest neighboring star Proxima Centauri bears a startling resemblance to our own sun, raising questions about conditions on its Earth-sized planet.
Proxima Centauri might be more sunlike than we thought. A fearless astronomer behind a game-changing telescope. New launch window under review. Discovery alert! Iron-made super Earth. The knowledge and tools NASA has developed to study life on Earth will be a great asset to the study of planets beyond our solar system. Our living planet shapes the search for life beyond Earth. A super Earth that scorches in extreme heat because it circles so close to its star.
A sizzling super Earth.

NASA researchers say they have passed a major milestone in their quest to detect the atmospheres of giant planets outside our solar system. NASA team passes major technological milestone for characterizing exoplanets. Icy moons, galaxy clusters, and distant worlds!

Oh my! SOFIA confirms nearby planetary system is similar to our own. NASA announces astronomy and astrophysics fellows for A team of scientists led by the Carnegie Institution for Science has released the largest collection of observations for hunting exoplanets to the public. Scientists make huge dataset of nearby stars available to public. University of Warwick researchers have identified a white dwarf pulsar — a star type which has eluded astronomers for half a century.
The vortex coronagraph has the potential to image planetary systems closer to their host stars than any other instrument in the world. Go beyond what's possible; that's the Spitzer Space Telescope's motto. Designed for a two-year mission, 13 years later it's still searching the skies for new discoveries. Spitzer Space Telescope begins 'Beyond' phase. The relatively nearby planet GJ b may have an atmosphere despite being baked to a temperature of around degrees Fahrenheit. Venus-like exoplanet might have oxygen atmosphere, but not life.
Astronomers have pinpointed which planets discovered by the NASA Kepler mission may sustain liquid water on their surfaces. Astronomers help focus research in the search for another Earth. To find Earth-like planets, NASA will face a challenge that seems impossible: build a space telescope so stable, it moves less than the width of an atom. The next generation of telescopes are almost impossibly accurate. A young star's stellar outburst brings its water snow line into view.
The bizarre idea of snow orbiting in space is fundamental to planet formation. Snow line discovered in bright baby solar system. Astronomers from UC Santa Cruz have found the first strong evidence of water vapor or ice in the the coldest known object outside our solar system— a brown dwarf five times the size of Jupiter. Astronomers find water clouds in cold Jupiter-like object.
How do some gas giant planets end up so feverishly close to their stars? In space 'Jupiter' planets burn hot, not cold. The organic molecule methyl alcohol methanol has been found for the first time in a young planet-forming disc. First detection of methyl alcohol in a planet-forming disc. A team of astronomers has found that there are far more planets of the hot Jupiter type than expected in a dense cluster of stars called Messier Unexpected excess of giant planets in star cluster.
