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...

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 finally confirmed the existence of two exoplanets — Proxima b and c — orbiting Proxima Centauri, the Sun’s closest stellar...

Astronomers have long used a so-called parallax effect — how a star appears to shift against its background when seen from different locations —...

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...
