Jupiter-like planet 8 UMi b, named Halla, orbits its host red giant star Baekdu closely. The red giant's merger with a white dwarf star questions how Halla could exist. Credit: Space.com | animation ...

This illustration shows an exoplanet orbiting around two brown dwarfs –– objects bigger than gas-giant planets but too small to be proper stars. ESO/M. Kornmesser Astronomers have discovered a ...

A Tatooine-like world with a key difference from the desert planet in "Star Wars" has been serendipitously discovered orbiting not two stars, but a pair of brown dwarfs. What's more, this wacky planet ...

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.

Astronomers have found the strongest evidence yet of a planet orbiting a binary-star system at close to a right angle 1. The system is also unusual in that both stars are brown dwarfs — objects larger ...

The newly discovered exoplanet HD 135344 Ab can be seen as a yellow dot on the right side of the image. It was measured in 2019 (2x), 2021, and 2022. The empty purple circle with the star in the ...

Scientists are observing an Earth-like exoplanet that may contain water using NASA's James Webb Space Telescope, the space agency said in a news release. The exoplanet, known as TRAPPIST-1 e, orbits ...

A bizarre planet defies cosmic norms: scientists have confirmed a giant planet orbiting in reverse around one star in a close binary system—an arrangement previously thought impossible. Using advanced ...

AUSTIN (KXAN) — A planet that scientists called a “hot Jupiter” is causing trouble for its solar neighbor. Labeled HIP 67522 b by scientists, this planet is 415 light-years from Earth. It is one of ...

Because their orbits are unstable, a possibility exists that the asteroids could break off from their current trajectory and one day head on a collision course for Earth. The Venusian space rocks are ...

Is there a massive undiscovered planet on the outer reaches of the solar system? The idea has been around since before the discovery of Pluto in the 1930s. Labeled as planet X, prominent astronomers ...

Luke found life on Tatooine to be boring, but he should be glad, because as we have seen, binary stars have the potential to play all kinds of havoc on their orbiting circumbinary planets. A ...
