This image of the colliding galaxy pair Arp 299 (also known as NGC 3690/IC694) was produced combining radio wavelength observations from the National Radio Astronomy Observatory's Very Large Array with data from the Hubble Space Telescope. Radio emission is shown as red, near-infrared emission as green, and ultraviolet emission as blue. This colliding pair is a region of vigorous star formation which has been investigated in the past. Since 1990, four supernova explosions have been seen optically in Arp 299. Observations with the NRAO's Very Large Array (VLA) showed a region near the nucleus of one of the colliding galaxies which had all the earmarks of prolific star formation. Observations with the VLBA and the GBT in 2002 and 2003 led to the discovery of 5 supernovae concentrated in this region. Posted on: 04 Nov, 2003
