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 ...

The discovery overturns traditional models that predicted gas giants in outer orbits and suggests planets can form in gas-poor environments.

A small red dwarf star in the Milky Way has drawn attention after astronomers mapped four closely orbiting planets around it. The system, known as LHS.

Since the 1990s, scientists have discovered approximately 6,100 planets outside our solar system, called exoplanets.

“Our job is to ensure our two GRAIL spacecraft are flying a very, very accurate trail formation in lunar orbit,” said David Lehman, GRAIL project manager at NASA’s Jet Propulsion Laboratory in ...
