The James Webb Space Telescope has caught a distant world in the act of falling apart, its outer layers peeling away into ...

For the first time, scientists have continuously monitored a planet's escaping atmosphere over a complete orbit, revealing ...

Using a powerful combination of space-based measurements and Subaru’s advanced imaging, astronomers have discovered two rare companions, one of which enables a key test for NASA’s Roman Space ...

Using the Webb telescope’s powerful Near Infrared Imager and Slitless Spectrograph (NIRISS) instrument, the team detected a ...

Analysis of early direct images from James Webb telescope show immense dust clouds on brown dwarf that lead to a blurring of ...

Stars form in massive clouds of gas called molecular clouds. As they form, they accrete gas from these clouds, and as the ...

Astronomers have been left puzzled by the discovery of an unusually large planet orbiting a remarkably small star, a cosmic pairing that defies existing theories of planetary formation. The star, ...

A new gas giant world discovered by citizen scientists using data from NASA's exoplanet-hunting spacecraft TESS is cool, literally and figuratively. This makes TOI-4465 b a rare case of a giant planet ...

A recent astronomical discovery has shaken long-held beliefs about how planets form. For decades, scientists thought that stars much smaller than our Sun couldn't form giant planets. That theory just ...

In the remote outer reaches of planetary systems, far beyond the orbit of known planets, enormous and mysterious worlds silently loop around their stars. Some drift as far as 10,000 times the distance ...

Astronomers have discovered that aging stars may be devouring their closest giant planets as they swell into red giants. Using NASA’s TESS telescope to study nearly half a million stars, scientists ...

New research from the University of St Andrews has found that giant free floating planets have the potential to form their own miniature planetary systems without the need for a star. In findings ...
