The Very Large Telescope's SPHERE instrument captured unprecedented images of 51 dusty rings shaping young planetary systems.

New high-contrast images from SPHERE show a stunning variety of debris disks shaped by collisions of tiny planet-building ...

An exoplanet the size of Jupiter has long intrigued astronomers because of its scorching temperatures, screaming winds and sideways rain made of glass. Now, data from the James Webb Space Telescope ...

When the Hubble Space Telescope set its sights toward the binary star system HD 106906, astronomers found a world that could resemble the long-sought Planet X. For the first time, astronomers are able ...

A pattern in the movements of a brown dwarf that orbits a Sun-like star is likely to be caused by a moon. If confirmed, this would be the first exomoon, that is a moon orbiting a planet that in turn ...

New measurements of radio galaxies reveal that the solar system is racing through the universe at over three times the speed predicted by standard cosmology. Using highly sensitive data from multiple ...

A distant star system housing 6 planets that move in 'mathematically perfect' orbits has ignited a search for possible alien technosignatures. When you purchase through links on our site, we may earn ...

Almost all planets in our solar system have moons – why not exoplanets? Astronomers believe they have discovered the first ...

Astronomers have identified a colossal exomoon candidate roughly seven Neptune masses orbiting the giant world HD 206893 B — ...

The NASA/ESA Hubble Space Telescope has made the first detection ever of an organic molecule in a planet orbiting another star. This breakthrough is an important step in eventually identifying signs ...

Astronomers may have identified the first known exomoon, orbiting a Jupiter-like exoplanet, amidst 6,000 confirmed exoplanets.
