Astronomers have spotted two planets forming around a distant infant star, offering a time capsule into see what the solar system looked like billions of years ago.
Extreme exomoons with tidal heating and thick, hydrogen-rich atmospheres may be able to create billions of years of potentially habitable surface conditions.
These worlds are among the least dense ever found, and all attempts to probe their atmospheres have been blocked by a mysterious smog.
Using the James Webb Space Telescope, astronomers have discovered an example of a new class of exoplanet, and it smells like rotten eggs.
Astronomers have witnessed evidence of an extremely violent collision between planets, and it resembles the event in Earth's history that created the moon.
The world's first commercial space telescope has released its first image as it begins its journey to help track nearby stars that might host habitable exoplanets.
Astronomers may finally understand why planets orbiting two suns, the real-world equivalents of the "Star Wars" planet Tatooine, are so scarce in our galaxy — and it has to do with general relativity.
A mysterious object has caused a long-lasting and extreme dimming of a distant star, but is this object a 'failed star' brown dwarf, or an exceptionally massive super-Jupiter exoplanet?
Astronomers have discovered a planetary system that appears to flip one of astronomy's most reliable rules on its head.
The planet is one of the best worlds for follow-up studies to determine whether it could be habitable or not.
