00:00 Astronomers, using NASA's Hubble Space Telescope, have recorded a star's final moments in detail
00:06 as it was ripped apart and eaten up by a black hole in a tidal disruption event.
00:12 The shredded star is nearly 300 million light-years away, but astronomers used Hubble's powerful
00:18 ultraviolet sensitivity to analyze its light to gather forensic clues of the violent event.
00:25 Hubble data found a very bright, hot, donut-shaped area of gas the size of the solar system swirling
00:32 around a black hole.
00:34 The swirling gas was once a star.
00:38 Usually, astronomers get just a few observations at the beginning of a disruption event, when
00:43 it's very bright.
00:44 But this energetic collision's proximity and brightness allowed Hubble to gather ultraviolet
00:50 data over a longer-than-normal time period.
00:54 This is a rare opportunity for scientists to create models of what they think is going
00:59 on and then compare those models with what Hubble sees.
01:03 It is an exciting place for scientists to be, right at the intersection of the known
01:10 and the unknown.
