NASA's Swift telescope re-enters atmosphere after 22 years

· Science · Indonesia · United States

NASA's Swift Observatory has re-entered Earth's atmosphere over Indonesia, ending nearly 22 years in orbit. The space telescope was originally designed to operate for just two years, but far outlived that plan and became a workhorse for studying the universe's most violent explosions. Swift transformed scientists' understanding of black holes, exploding stars and other mysterious cosmic outbursts, and its re-entry closes out a mission that shaped high-energy astrophysics for more than two decades.

Why it matters：The loss of Swift removes a long-serving asset for detecting gamma-ray bursts, a capability that underpins much of the field's time-domain astronomy and leaves a gap until replacement missions come online.

Key points

  • Swift re-entered over Indonesia after nearly 22 years in space.
  • It was designed for a two-year mission but operated far longer.
  • Its observations reshaped the study of black holes and exploding stars.
