General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” of ...

Some of the most promising places to look for extraterrestrials have remained, so far, mostly hidden from astronomers. Now a game-changing instrument called NIRPS (Near-Infrared Planet Searcher) is ...

Astronomers have uncovered a distant planetary system that flips a long-standing rule of planet formation on its head. Around the small red dwarf star LHS 1903, scientists expected to find rocky ...

'How planets revolve' is possibly one of the first extraterrestrial phenomena that educators taught students at school. They are told that in this phenomenon, the planets move around the sun in fixed ...

A planet circling at a sharp 90-degree angle to the orbits of its two host stars has now been confirmed. This discovery challenges long-standing ideas about how planets form and orbit in the cosmos.

The planets are visible throughout February, "but they’ll be lined up best toward the end of the month,” NASA says.

Could we prevent in-orbit crashes in the future by using advanced computer models?

A planetary system 116 light-years from Earth has a peculiar pattern. It could flip the script on how planets form, scientists say.
