What you need to know
Swift has studied over 2,000 gamma-ray bursts and more than 1,400 supernova explosions.
The telescope has contributed to about 7,000 scientific papers.
Swift was designed to quickly detect and locate gamma-ray bursts.
The telescope's data has been used to validate models about the origins of short gamma-ray bursts.
It is not yet known exactly when and where Swift will re-enter the atmosphere or where any surviving pieces will land.
Background
NASA's Swift telescope, also known as the Neil Gehrels Swift Observatory, was launched in 2004. It was designed to study gamma-ray bursts, the most powerful explosions in the universe. Over the years, Swift has made significant contributions to astronomy, studying a wide range of cosmic events and objects.
Swift's orbit has decayed over time, and it is now expected to re-enter the atmosphere in the next few weeks. The telescope has conducted its final observation and is no longer able to compensate for the increased drag at its current altitude.
Despite its impending re-entry, Swift has left behind a significant legacy. The telescope has observed thousands of gamma-ray bursts and supernova explosions, and its data has been used in thousands of scientific papers. Swift's rapid response capabilities and multiwavelength observations have revolutionized our understanding of the universe.
