The observatory made its final observation on Oct. 20 and is expected to re-enter Earth’s atmosphere in the next few weeks, NASA says.

- NASA says Swift observed more than 2,000 gamma-ray bursts and studied more than 1,400 supernova explosions.

Why it matters: Swift’s archive of multiwavelength observations will remain available for future research, NASA says.

What’s next: NASA expects the spacecraft to re-enter the atmosphere in the next few weeks.
