Hubble View Of Runaway Black Hole Leaves Massive Streak Of Stars In Its Wake

  • 2 months ago
The Hubble Space Telescope has imaged a "200,000 light-year-long trail of newborn stars" that may have been left behind by a runaway supermassive black hole.

Schematic illustration of the runaway SMBH scenario as an explanation of the key observed features. Panels 1–5 show a “classical” slingshot scenario (e.g., Saslaw et al. 1974). The background of panel 6 is a frame from an Illustris TNG simulation (Pillepich et al. 2018)

00:00There's an invisible giant monster on the loose!
00:03It's barreling through intergalactic space, fast enough to travel from Earth to the Moon
00:08in 14 minutes.
00:10But don't worry, luckily this beast is very, very far away.
00:16This potential supermassive black hole, weighing as much as 20 million suns, has left behind
00:22a never-before-seen 200,000 light-year-long trail of newborn stars.
00:28The streamer is twice the diameter of our Milky Way galaxy.
00:32It's likely the result of a rare, bizarre game of galactic billiards among three massive
00:37black holes.
00:39Astronomers suspect that first two galaxies merged perhaps 50 million years ago.
00:45That brought together two supermassive black holes at their centers.
00:49They whirled around each other until another galaxy came along with its own supermassive
00:54black hole.
00:55The three of them chaotically orbited around each other.
00:58This unstable configuration couldn't last, and eventually one of them was violently flung
01:03out of the host galaxy.
01:06Rather than gobbling up stars ahead of it, this speedy black hole is plowing into gas
01:11in front of it to trigger new star formation along a narrow corridor.
01:16The next step is to do follow-up observations with NASA's James Webb Space Telescope and
01:22the Chandra X-ray Observatory.
01:24Also, NASA's upcoming Nancy Grace Roman Space Telescope will have a wide-angle view of the
01:30universe with Hubble's high resolution.
01:33As a survey telescope, the Roman observations might find more of these rare and improbable
01:39events elsewhere in the universe.
01:42Hubble, once again showing us that the universe is full of fascinating phenomena.
