New estimate suggests that 18% of Sun-like (G-type) stars could have a planet the size of Earth orbiting in their conservative habitable zone.
There may...
Using the assumption that intelligent life develops on exoplanets in a similar way as it does on Earth, a duo of researchers from the School of Physics...
Peter Pan disks are a recently-discovered class of long-lived protoplanetary disks around low-mass stars that survive 5-10 times longer than typical protoplanetary...
Astronomers using data from NASA’s Kepler space telescope have discovered two new planets in the Kepler-160 planetary system. One of the new planets...
Astronomers using the NASA/ESA Hubble Space Telescope have observed young stars in a crowded stellar cluster called Westerlund 2. They’ve found that...
Using three instruments on ESO’s Very Large Telescope (VLT), an international team of astronomers has discovered and imaged a giant sub-stellar object...
Astronomers using the SPHERE (Spectro-Polarimetric High-contrast Exoplanet Research) instrument on ESO’s Very Large Telescope (VLT) have observed a protoplanetary...
Using the Near-Infrared Camera (NIRC2) on the Keck II telescope at W. M. Keck Observatory on Maunakea in Hawaii, astronomers have directly imaged two infant...
In a new study published this week in the Proceeding of the National Academy of Sciences, Dr. David Kipping of Columbia University and Flatiron Institute...
An international team of astronomers has discovered a close-in super-Earth exoplanet in the HD 164922 planetary system.
An artist’s impression of the...
Astronomers have discovered a super-Earth exoplanet orbiting a dwarf star or a brown dwarf around 7,580 parsecs (24,723 light-years) from Earth.
An artist’s...
Using data from the NASA/ESA Hubble Space Telescope, NASA’s Spitzer Space Telescope, and Magellan II Telescope at Las Campanas Observator in Chile, astronomers...
A team of researchers at the Massachusetts Institute of Technology (MIT) has demonstrated that single-celled microorganisms such as Escherichia coli and...
A team of astrobiologists from the Carl Sagan Institute at Cornell University has developed a spectral field guide for Earth-like exoplanets transiting...
Using the High-Resolution Echelle Spectrometer (HIRES) instrument on the 10-m Keck I telescope at W.M. Keck Observatory, astronomers have discovered a...
The directly-imaged massive exoplanet Fomalhaut b is actually a dispersing cloud of dust, produced by a catastrophic collision between two large planetesimals...
Comets spend most of their lives at large distances from any star, during which time their interior compositions remain relatively unaltered. Cometary...
