A team of astronomers from Israel and the United States has discovered a vast stream of 250 stars of extragalactic origin in the vicinity of our Solar...
Astronomers using the SuperWASP-North telescope on La Palma in the Canary Islands, Spain, and the SOPHIE spectrograph at the Observatoire de Haute-Provence,...
Our Solar System contains a large population of icy bodies stretching well beyond the orbit of Neptune. These objects are remnants from the early formation...
Astronomers have analyzed a few carbon-oxygen white dwarfs in Milky Way’s old open clusters, and their findings help shed new light on the origin of...
Using NASA’s Transiting Exoplanet Survey Satellite (TESS) and several ground-based telescopes, astronomers have discovered and confirmed a warm super-Neptune...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) and NSF’s Karl G. Jansky Very Large Array (VLA) have created the most detailed...
Using the Atacama Large Millimeter/submillimeter Array (ALMA) and the NASA/ESA Hubble Space Telescope, astronomers have observed G286.21+0.17, a massive...
The newly-discovered planetary core, named TOI-849b, is a gas giant that was either stripped of its gaseous atmosphere or that failed to form one in its...
New observations from NASA’s Transiting Exoplanet Survey Satellite (TESS) have enabled astronomers to improve their understanding of the bizarre environment...
The Breakthrough Listen Initiative, the largest ever scientific research program aimed at finding evidence of alien civilizations, has conducted a search...
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) and Spitzer Space Telescope have discovered a planet about the size of Neptune...
Astronomers have discovered and validated two small exoplanets orbiting the nearby red dwarf star TOI-1266.
An artist’s impression of the TOI-1266 planetary...
A new all-sky image from the eROSITA X-ray telescope onboard the Spectrum-Roentgen-Gamma (SRG) space observatory contains over one million objects, about...
A team of U.S. astronomers has calculated internal heating rates for 53 terrestrial exoplanets and found that all of them are likely to have volcanic activity...
Planetary nebulae, whose stars shed their layers over thousands of years, can turn into crazy whirligigs while puffing off shells and jets of hot gas....
Using data from NASA’s Kepler/K2 mission, the SPECULOOS telescopes and the High Resolution Echelle Spectrometer (HIRES) on the Keck I telescope at W.M....
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...
Astronomers have detected the signatures of two complex organic molecules, methanol and acetaldehyde, in starless and prestellar cores of the Taurus Molecular...
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...
