NASA spots a wild, speedy red sphere zooming through our galaxy

Technology Nov 24, 2025

NASA just found something pretty wild: a mysterious red object called CWISE J1249 racing through the Milky Way at over a million miles per hour.
Spotted by the WISE telescope, this fast-moving sphere is so strange that scientists aren't sure if it's leftover from an exploded star or maybe even a planet that got kicked out of its home.

Why everyone's geeking out about CWISE J1249

What makes this space traveler special? It's super light, has barely any metals, and its makeup doesn't fit anything scientists have seen before.
All these odd features are making researchers rethink what they know about how stars and planets form—so CWISE J1249 could challenge existing theories in astronomy.
