View Full Version : Discussion: Galaxy Stripped Clear Of Star ...

2004-Jun-04, 10:23 PM
SUMMARY: A new photo of spiral galaxy NGC 4402 shows how it's being stripped of its star forming material as it falls towards the Virgo super cluster - and experiences a wind from the hot cluster gas which can reach millions of degrees. The photo was taken using the WIYN 3.5-metre telescope at Kitt Peak, and it shows how the galaxy is actually being bowed upward from the galactic "wind" blowing from the lower left of the image. Once the cold gas is fully blown out of the galaxy, it will be essentially dead, and incapable of forming new stars like regular galaxies.

What do you think about this story? Post your comments below.

Just how strong/fast is galactic wind supposed to be?

why can't all the stars just learn to get along with each other.

Near the center of a supercluster, it's strong. There's usually a massive eliptical galaxy at the center of a cluster, and it's so hot and active it "kills" normal galaxies that even get near it.

Also, just a nit-pick here, it's intergalactic wind. ;)

And I have a nit pick, too. This galaxy won't be dead. It will still have its own stars. When they die they'll kick new clouds of gas and dust into the the galaxy, and those will form new stars. It'll take a while, but it will happen.
