Scientists have shown that the building blocks of proteins can form naturally in deep space. This means the raw ingredients for life may exist long before planets are formed.

The interstellar visitor may still have a few things to tell us before it leaves our solar system.

Scientists found new evidence (or lack thereof) disproving the conspiracy theory that interstellar comet 3I/ATLAS is alien technology.

NASA’s Transiting Exoplanet Survey Satellite has once again surprised astronomers by tracking interstellar comet 3I/ATLAS, a ...

New experiments reveal that protein precursors can form naturally in deep space under extreme cold and radiation. Scientists found that simple amino acids bond into peptides on interstellar dust, long ...

Astronomers found an interstellar "tunnel" - a cosmic channel that connects our solar system to distant stars, according to a ...

Interstellar comet 3I/ATLAS is tearing across the inner solar system at roughly 130,000 miles per hour, a speed that turns ...
