NASA's Great Observatories -- Chandra, Spitzer, and Hubble -- have collaborated on this magnificent composite image of the Antennae Galaxies, a pair of galaxies that are merging with each other in a 100-million-year-long fireworks display.
Chandra's image shows hot, element-rich gas in the X-ray spectrum; Spitzer shows the infrared, with warm dust clouds in the region of stars being born amid the collision; and Hubble shows older stars.
Looks like STOP motion to me, not slow motion. This is, after all, one image.
Well, stick around a few billion years and enjoy the show when Andromeda and the Milky Way collide! That will be stunning if your around!
I don't know, gizmowiz, I have an appointment with my barber sometime at that time precisely... give or take!
But my point was that slow motion is a video technique ;-)
Its not really slow, its just that because of the huge masses of each galaxy and the fact that our perspective is so far away that that appears to be the case... just saying.
