Astronomers have located a rare exoplanet on the edge of the Milky Way. The exoplanet, a gas giant named AT2021uey b, orbits a low-mass star and is located about 3,200 light-years away from Earth, ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

One of the biggest puzzles in modern cosmology is the existence of dark matter, which constitutes most of the matter in the universe. Recent research by an international team of researchers has used ...

If, as astronomers believe, the death of large stars leave behind black holes, there should be hundreds of millions of them scattered throughout the Milky Way galaxy. The problem is, isolated black ...

Planets that go rogue orbit no star. They wander the vacuum of space alone, having been kicked out of their star systems by gravitational interactions with other planets and stars. Nobody really knows ...

This graphic shows how microlensing was used to measure the mass of a white dwarf star. The dwarf, called LAWD 37, is a burned-out star in the centre of this Hubble Space Telescope image. Though its ...

Planets usually stay close to their host stars, tracing steady paths shaped by gravity. Yet some planets break free and drift alone through the Milky Way. Astronomers call these objects free-floating ...
