rogue planets

Using the James Webb Space Telescope, astronomers have made the shock discovery that giant rogue exoplanets can grow their own planetary systems without needing a parent star.

"This discovery was partly serendipity! But, we believe there are many more such opportunities hidden in Hubble data."

The sun could collect rogue planets and hold them at the outskirts of the solar system for millions of years, occasionally trading them with neighboring star Alpha Centauri.

"Twisted Tatooine" binary star systems could be a major player in ejecting rogue planets that go on to drift through the Milky Way without a stellar parent to heat or illuminate them.

Scientists may have discovered how JuMBOs, strangle binary objects found in Orion, may have gone rogue while staying gravitationally bound. The discovery may shake up theories of planet formation.

One of the instrument's early programs includes performing spectroscopy on stellar nursery NGC 133 to spot the small, dark celestial bodies.

Finding more and more exoplanets to study has, as we might have expected, widened our understanding of what a planet is.

These planets, including Earth, benefit from the star’s warmth and light.

A distant alien world that was potentially on its way into exile in interstellar space was rescued by the gravitational pull of a passing pair of stars, a new study argues.
