Astronomers using data from NASA’s Transiting Exoplanet Survey Satellite have discovered a super-Earth orbiting an unusually bright, Sun-like star called...
Astronomers using data from the Kepler spacecraft’s K2 mission have discovered two mini-Neptune exoplanets orbiting a star in an open star cluster called...
Astronomers have largely assumed that water-world exoplanets would not support the cycling of minerals and gases that keeps the climate stable on Earth,...
A duo of astronomers at Leiden University in the Netherlands has deduced the mass of Beta Pictoris b from the motion of its parent star, which lies 63...
A research team led by Harvard University astronomer Li Zeng has shown that water is likely to be a major component of extrasolar planets which are between...
Astronomers have detected atomic iron and titanium in the atmosphere of KELT-9b, a gas giant exoplanet orbiting a star in the constellation Cygnus, about...
Have Carl Sagan and astrobiologists been too hard on stellar flares? A new study imagines an alternative scenario where they power photosynthesis around...
Close encounters between stars in Omega Centauri, the only star cluster visible to the naked eye, leave little room for habitable planets, according to...
Recent observations by NASA’s space telescopes of ultrahot Jupiter-like exoplanets have surprised astronomers. The spectra of these planets have suggested...
Astronomers using NSF’s Karl G. Jansky Very Large Array have detected a ‘rogue’ planetary-mass object with a surprisingly powerful magnetic field.
Artist’s...
Scientists from the University of Cambridge and the MRC Laboratory of Molecular Biology, UK, have identified a group of exoplanets where the same chemical...
A team of astronomers at Carl Sagan Institute, Cornell University, has produced a reference catalog of spectra and geometric albedos for 19 objects that...
There may be more habitable exoplanets than we previously thought, according to Pennsylvania State University researchers Bradford Foley and Andrew Smye,...
NASA’s Transiting Exoplanet Survey Satellite (TESS) has begun its search for planets around stars within 300 light-years of the Sun.
An artist’s illustration...
Astronomers have discovered an exoplanet with several times the mass of the Earth orbiting a nearby star. A paper reporting this discovery is published...
For decades, astronomers have puzzled over the variability of young stars residing in Taurus-Auriga dark clouds, a group of molecular clouds located in...
Astronomers have discovered a giant gaseous planet orbiting a pair of brown dwarfs called 2MASS J02495639-0557352AB (2MASS 0249 for short). The new exoplanet,...
Understanding which chemical elements are present in a star in what abundances can help astronomers estimate the makeup of planets that orbit them, which...
Astronomers using the SPHERE instrument on ESO’s Very Large Telescope have found an infant gas giant orbiting the young dwarf star PDS 70. Not only have...
