A gas giant called WD 1856 b has done something no planet was supposed to survive. Its star aged, swelled into a red giant, and collapsed into a white dwarf, the burned-out cinder a Sun-like star leaves behind. The planet is still…

The planet’s name is HD 189733b. It is one of the closest extrasolar planets to Earth that can be studied in detail, and one of the most thoroughly characterised exoplanets in the astronomical literature. Its star, HD 189733, sits in the…

Under the best circumstances, a trip from Earth to Mars and back would take a spacecraft three years to complete.And that's during a very specific orbital alignment that occurs once every two years or so as the two planets travel around…

Astronomers have identified a planet composed of molten lava, suggesting the existence of an entirely new category of liquid planet.The distant world, known as L98-59d, is about 1.6 times the size of Earth and orbits a small red star 35…

Astronomers have discovered a potentially habitable new planet about 146 light-years away which is Earth-sized and has conditions similar to Mars.The candidate planet, named HD 137010 b, orbits a sun-like star and is estimated to be 6%…

Most of the exoplanets we’ve discovered have been in relatively tight orbits around their host stars, allowing us to track them as they repeatedly loop around them. But we’ve also…

Not all planets are lucky enough to live in a neighborhood like our Solar System – some are doomed to roam the cosmos alone. Astronomers have now, for the first time, measured the mass of, and distance to, one of these lonely…

Roughly 1,000 light-years away from Earth, a gigantic disk of gas and dust is swirling around a young star and giving rise to new planets. Not only is it the largest planet-forming disk astronomers have ever found, its…
