ESO 137-001

ESO 137-001 is a barred spiral galaxy[2] located in the constellation Triangulum Australe and in the cluster Abell 3627.[6] As the galaxy moves to the center of the cluster at 7 million kilometers per hour,[4] it is stripped by hot gas thus creating a 260,000 light-year long tail.[6] This is called ram pressure stripping.[5] The intergalactic gas in the Abell 3627 is 100 million degrees Celsius (180 million degrees Fahrenheit) which causes star formation in the tails.[5][6]

History

The galaxy was discovered by Dr. Ming Sun in 2005.[7]

Galaxy's fate
Observations reveal motion of gas as it is ripped out of the galaxy.[8]

The stripping of gas is thought to have a significant effect on the galaxy's development, removing cold gas from the galaxy, shutting down the formation of new stars in the galaxy, and changing the appearance of inner spiral arms and bulges because of the effects of star formation.

gollark: If you had a web backend for it, you could easily enough have other servers run their own webservers.
gollark: But if anyone *can* plug something in, it's exactly as secure as wireless, or actually less because you can access peripherals.
gollark: If nobody else has access to your cables they can't see the messages running on them, yes.
gollark: What?
gollark: You can do exactly the same things over network lines as you can over wireless, with the addition of being able to access peripherals.
