Across the Milky Way and beyond, planetary systems appear to fall into a few recurring blueprints, and recent exoplanet ...

New measurements of radio galaxies reveal that the solar system is racing through the universe at over three times the speed predicted by standard cosmology. Using highly sensitive data from multiple ...

NASA’s Goddard Space Flight Center shared the images of comet 3I/ATLAS. It's possibly as big as Manhattan, likely older than our own solar system and it's traveling through space at speeds of up to ...

"If our solar system is indeed moving this fast, we need to question fundamental assumptions about the large-scale structure of the universe." When you purchase through links on our site, we may earn ...

How fast and in which direction is our solar system moving through the universe? This seemingly simple question is one of the key tests of our cosmological understanding. A research team led by ...

The search for an unknown planet in our solar system has inspired astronomers for more than a century. Now, a recent study suggests a potential new candidate, which the paper’s authors have dubbed ...

Add a description, image, and links to the solar-system-simulation topic page so that developers can more easily learn about it.

Astronomers have uncovered a massive new trans-Neptunian object, 2017 OF201, lurking at the edge of our solar system. With an orbit stretching 25,000 years and a size that may qualify it as a dwarf ...

Here’s what you’ll learn when you read this story: Object 3I/ATLAS is now too far from Earth to aim a telescope at, but prior observations showed some unusual behavior. The anomalous nature of the ...

Called 3I/ATLAS, the object is only the third of its kind known to astronomers, and it’s likely been heading our way for billions of years, carrying pristine material from another star system Jay ...
