NASA Chandra Image: Short Sharp Science: Collision-course galaxies form cosmic exclamation mark

Image: X-ray: NASA/CXC/IfA/D. Sanders et al.; optical: NASA/STScI/NRAO/A. Evans et al.
 
An opening act to their merger millions of years from now, these colliding galaxies get exclamatory in this newly released image from the Chandra X-ray Observatory.

The duo, known collectively as VV 340, consists of the sideways-on North galaxy on top and the face of the south galaxy forming the bottom point.

The vibrant purple glow represents X-ray data, and the shades of red, green and blue are optical information from the Hubble Space Telescope.

Observations from Chandra suggest VV 340 North conceals a rapidly growing supermassive black hole within its stardust.

The cosmic punctuation mark resides some 450 million light years from Earth.
