A new study has found that planets orbiting TRAPPIST-1, an ultracool dwarf star 38.8 light-years away in the constellation Aquarius, are mostly made of...
Using a quasar microlensing technique, astronomers claim to have found a large population of unbound planets — with masses ranging from Moon to Jupiter...
Astronomers using data from the NASA Kepler spacecraft’s reborn K2 mission have found a triple system of super-Earth exoplanets around a cool star called...
A team of astrobiologists from the Universities of Washington and California has found a simple approach to look for alien life that might be more promising...
In a new article published in the Astrophysical Journal (arXiv.org preprint), Johns Hopkins University researcher Kevin Schlaufman sets the upper boundary...

A study of 909 exoplanets in 355 multi-planet systems discovered by NASA’s Kepler Space Telescope reveals that, unlike our Solar System, other planetary...
Astronomers studying RZ Piscium, a variable Sun-like star located approximately 555 light-years away in the constellation Pisces, have found evidence suggesting...
A research team led by University of Hawaii astronomers has found two remarkably similar gas giants orbiting very close to their parent red-giant stars.
The...
There may be small, rocky planets in the nearby Alpha Centauri triple-star system that have been overlooked, according to a new study published in the...
A team of researchers reports the discovery of an eighth planet orbiting Kepler-90, a Sun-like star approximately 2,545 light-years from Earth in the constellation...
WASP-18b, a hot-Jupiter exoplanet located approximately 325 light-years from Earth, has a stratosphere that’s loaded with carbon monoxide, but has no...
An international team of astronomers has found that a little-known exoplanet called K2-18b could be a scaled-up version of Earth, and also discovered the...
Streams of space dust that continually bombard Earth’s atmosphere could deliver microbial life and life essential molecules from distant planets, or...
A rocky exoplanet roughly the same size as Earth has been discovered orbiting a nearby low-mass star, thanks to new data gathered by ESO’s High Accuracy...
