Scientists using NASA's James Webb Space Telescope have observed a rare type of exoplanet, or planet outside our solar system ...

Jupiter-like planet 8 UMi b, named Halla, orbits its host red giant star Baekdu closely. The red giant's merger with a white ...

But in this case, the companion is officially considered an exoplanet, not a star. The International Astronomical Union ...

These six planets are in perfect sync with each other as they dance through space around their star. Credit: Roger Thibaut (NCCR PlanetS) Astronomers have observed a solar system where six planets are ...

In 2020, astronomers detected WD 1856+534 b, a gas giant that orbits a star 81 light-years from Earth. This exoplanet, which is roughly six times the mass of Jupiter (making it a "super-Jupiter"), was ...

Astronomers are increasingly finding planets that do not simply circle their stars in neat, clockwork ellipses but instead trace out paths that look more like intricate choreography. The latest ...

An illustration of the solar system and the planet's orbits around the sun When you're standing on Earth's surface, it's easy to forget that our planet is hurtling around the sun at more than 67,000 ...

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 ...

One hundred light years away, a handful of planets are circling a star in the same configuration as when they formed. By Katrina Miller Astronomers have discovered six planets orbiting a bright star ...

Studying the orbits of thousands of exoplanets shows that large planets tend to have elliptical orbits, while smaller planets tend to have more circular orbits. This split coincides with several other ...

For the inner four planets in this solar system, each planet orbits the sun three times for every two orbits of the planet immediately to its outside. For the fourth, fifth and sixth planets, they ...

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 ...
