An international research team has discovered a new planet so young that it has yet to emerge from the womb of matter where it is forming. This is the youngest protoplanet discovered to date. It's ...

For decades, scientists have studied how planets form by looking at young stars nearby, assuming that these environments could be representative of all star systems. However, as astronomers discover ...

Odd bursts, shifting expansion rates, and oversized early galaxies are pushing astronomers to refine physics, not rewrite it, ...

Billions of years ago, in the frozen edges of the solar system, a violent impact shaped one of space’s oddest pairs. Instead of a typical planet-moon setup, Pluto and Charon became a binary system.

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