For years, the center of our galaxy has been painted as a place where stars go to meet their end — a region ruled by ...

Why do comets and their meteoroid streams weave in and out of Earth's orbit and their orbits disperse over time? Researchers show that this is not due to the random pull of the planets, but rather the ...

Planet hunters have grown used to strange worlds, but a handful of discoveries now point to something even more radical: ...

Astronomers measure the speed at which the solar system is hurtling through space by mapping surrounding galaxies and ...

Some white dwarfs in rapid binary orbits are far hotter and larger than theory predicts. Researchers found that powerful tidal forces between them generate enough heat to inflate their sizes and ...

While our Sun prefers to go solo, many other stars are parts of binary systems, with a pair of stars gravitationally bound to each other. In some cases, the stars are far enough apart that planets can ...

YouTuber "The 5439 Workshop" has built a solar system coffee table with a miniature, mechanically-exploding star system.

Astronomers have discovered a rare solar system with six planets moving in sync with one another. Estimated to be billions of years old, the formation 100 light-years away may help unravel some ...

From an early age, we are taught to understand that the planets of our solar system change in position while orbiting a central star, the sun. But does the sun itself move within the solar system?

(KTLA) — Earth will soon have two moons, but not for long. According to a study published in the journal Research Notes of the American Astronomical Society (AAS), the “moon” in question is a ...

The meteoroid stream of long-period comet Thatcher (white line). Each meteoroid moved on its own orbit and created a Lyrid shower meteor when it hit Earth after approaching the orbit of Earth (blue ...
