What would it take to accelerate to Interstellar space by a NASA spacecraft deliberately, within a time that is short enough that the people who designed it and studied it will be available to analyze the findings?

The comet contains higher levels of this simple alcohol than almost all known comets from our solar system.

Astronomers have spotted something unusual in a comet passing through our Solar System. 3I/ATLAS, only the third confirmed interstellar visitor ever s.

The Princeton-led NASA mission has officially begun its science mission to study the sun and everything it touches. Princeton marked the occasion with a panel discussion, science talks and a reception.

Interstellar comet 3I/ATLAS has steadily been making its exit ever since it had a rendezvous at the end of October with the sun.

Interstellar Comet 3I/ATLAS is the gift that keeps on giving. A snapshot of the space that lies beyond the solar system, it brings clues to other stars, other worlds and the galaxy we call home. Just three such interstellar objects have ever been discovered, and by studying each one, we learn more about what’s outside our cosmic neighborhood.

NASA's most distant spacecraft had a critical thruster problem far from home. Fixing it required a long-distance call to overcome extreme cold and dwindling power. When you purchase through links on our site, we may earn an affiliate commission. Here’s ...

An international team of scientists has examined dust grains gathered by the NASA Stardust spacecraft and brought back to Earth – and has discovered that they originated in the interstellar dust stream. With the help of citizen scientists, the research ...

Astronomers using ALMA have found large quantities of methanol in comet 3I/ATLAS, making it one of the most alcohol-rich comets ever detected. Scientists are gaining more insights in this case, as methanol is not found in space.

The interstellar comet 3I/ATLAS is leaving our solar system. See new photos from a European Space Agency orbiter on its way to Jupiter.
