The Milky Way galaxy has billions of stars in its folds. If each of these stars hosted a planetary system, then the number of planets outside our solar system—exoplanets—would easily reach trillions, ...

Astronomers have found what appears to be one of the strangest known worlds in the universe. It orbits a type of rapidly spinning neutron star called a pulsar – this in itself is unusual, but it is ...

Scientists using NASA’s James Webb Space Telescope have observed an entirely new type of exoplanet whose atmospheric composition challenges our understanding of how this type of planet forms. This ...

OK, first, let’s get the name out of the way. Scientists have cataloged this exoplanet as PSR J2322-2650 b. It’s called that because it orbits a pulsar (a rapidly rotating neutron star) designated PSR ...

Astronomers are just beginning to scratch the surface of the complex, and sometimes violent, relationships between planets and their parent stars. When you purchase through links on our site, we may ...

Astronomers have captured some of the most detailed images of debris discs—rings of leftover dust, gas, and rocks that circle a star—from fully formed, "teenage" planetary systems. And those images, ...

Since astronomers found the first planets outside our solar system in 1992 and the first planet around a sunlike star in 1995, scientists have sought the telltale glimmers, flickers and wobbles that ...

This ARKS gallery of faint debris disks reveals details about their shape: belts with multiple rings, wide smooth halos, sharp edges, and unexpected arcs and clumps, which hint at the presence of ...
