Comet 3I/ATLAS, the third known interstellar object ever detected passing through our solar system, carries a chemical signature that does not match what astronomers typically see in comets born ...

In the distant reaches of the solar system are many icy objects that resemble snowmen. Now, a new study reveals the simple ...

Learn how ALMA observations revealed unusually high levels of methanol in interstellar comet 3I/ATLAS and what the molecule’s chemistry may reveal about how icy bodies form around other stars.

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 ...

It may not feel like it, but everything in the universe is in constant motion. Our Sun, with all its planets, orbits the center of the Milky Way, flying through the cosmos at around 450,000 miles per ...

Analysis reveals what appears to be a channel of hot, low-density plasma stretching out from our solar system toward distant ...

Illustration comparing the planets of the Solar System and the Sun on the same scale. The planets are shown to scale relative to each other but their distances are not. From left to right the bodies ...
