One million alien visitors from another star system could already be lurking in the solar system. We aren't talking about ...

"We found that some comets in the inner Oort cloud form a long-lasting spiral structure." Spirals are a repeating theme in ...

The mysterious Oort cloud is the source of many of our solar system's comets, but astronomers still have no idea what it looks like. Now, new simulations may have given them a first glimpse.

11, 2025 — A new study presents a compelling new model for the formation of super-Earths and mini-Neptunes -- planets that are 1 to 4 times the size of Earth and among the most common in our galaxy.

Our sun belongs to a spiraling galaxy filled with star-forming neighborhoods. Astronomers recently found that our entire solar system traveled through a dense region near the constellation Orion about ...

This Thursday night, for the first time in nearly two-and-a-half years, our planet's faithful companion is going to get fancy and put on a lovely shade of rouge.

Scientists have determined that around 14 million years ago, our Solar System traveled through a densely populated galactic region and might have experienced increased interstellar dust, which could ...

Earth has a nearly circular orbit, but some planets outside our solar system, called exoplanets, have very elliptical orbits. UCLA astrophysicists have now measured the shape of the orbits of ...
