Intense radiation from host stars could strip away the ozone layer of Earth-like exoplanets and render them uninhabitable, according to a new study presented...
An international team of astronomers has discovered a planetary system containing at least three massive planets, orbiting the bright late-G/early-K-type...
An international team of astronomers has announced the discovery of twelve planets orbiting nine low-mass stars. The discovery is based on data from the...
Nestled in the Ophiuchus star-forming region, approximately 410 light-years from the Sun, a fascinating protoplanetary disk around the young star AS 209...
Astronomers using NASA/ESA Hubble Space Telescope have detected water vapor in the atmosphere of a Saturn-mass exoplanet known as WASP-39b. By combining...
Using data from the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers discovered that a giant stellar flare erupted from Proxima Centauri...
Astronomers using data from NASA’s extended Kepler mission, known as K2, have discovered 95 new exoplanets, with sizes ranging from mostly rocky super-Earths...
A bright K-type dwarf star called Gliese 9827 hosts one of the most massive (and dense) super-Earths detected to date, according to a study to be published...
Like a teenage diary you can’t throw away, Mars might carry a reminder of its difficult formative years in its tiny moons. A paper published by the Royal...
Astronomers using the NASA/ESA Hubble Space Telescope have conducted the first spectroscopic survey of exoplanets within the habitable zone around TRAPPIST-1....
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...
Viruses are the most abundant and one of the least understood biological entities on modern Earth. They might also exist in space, but as of yet scientists...
An international team of citizen scientists and professional astronomers has discovered a system of at least five massive exoplanets, orbiting the Sun-like...
Using the NASA/ESA Hubble Space Telescope to peer deep into the famous Orion Nebula, Space Telescope Institute researcher Massimo Robberto and colleagues...
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...
