Jupiter-like planet 8 UMi b, named Halla, orbits its host red giant star Baekdu closely. The red giant's merger with a white ...

On October 6 1995, at a scientific meeting in Florence, Italy, two Swiss astronomers made an announcement that would transform our understanding of the universe beyond our solar system. Michel Mayor ...

The James Webb Space Telescope has detected clouds made of silicates, similar to sand here on Earth, as well as water, methane and carbon monoxide on exoplanet VHS 1256 b. The exoplanet is more ...

Because the Earth is doing the work of increasing the Moon's momentum, the Earth's rotation slows down in turn, as its momentum goes to the Moon. To put it another way, as the Moon's orbital momentum ...

A low-density, puffy planet orbiting relatively far from a young star in a nearly perpendicular orbit. What's going on?

Astronomers spotted a young planet, WISPIT 2b, forming within a dusty ring around its star system, offering clues about the ...

Astronomers detected a bright signal, coming from deep inside a dust disc, that is likely newborn planet HD 135344B still ...

Scientists are observing an Earth-like exoplanet that may contain water using NASA's James Webb Space Telescope, the space agency said in a news release. The exoplanet, known as TRAPPIST-1 e, orbits ...

The official number of exoplanets—planets outside our solar system—tracked by NASA has reached 6,000. Confirmed planets are added to the count on a rolling basis by scientists from around the world, ...

New research suggests a rocky “lava planet” orbiting very close to its star likely carries an atmosphere. Astronomers found an atmosphere where they least expected it—clinging to an exoplanet that’s ...

NASA has confirmed 6,000 exoplanets, marking a major milestone in humanity’s quest to understand other worlds. From gas giants hugging their stars to planets covered in lava or clouds of gemstones, ...

Astronomers have spotted a quasi-moon near Earth — and the small space rock has likely been hanging out near our planet unseen by telescopes for about 60 years, according to new research. The newly ...
