These galaxies might not necessarily be touching, but they're pretty close from where we're seeing them.
The cluster, known as Arp 274 or the NGC 5679 group, is actually three separate galaxies captured in one shot by NASA's Hubble telescope. The image, which was taken by the Hubble Telescope in April, captures a cluster that sits about 400 million light-years from Earth, in the constellation Virgo.
While the largest of the three galaxies is the center one (all three lie at different distances and may be different sizes respectively due to spacing), the outer galaxies are both forming stars at an incredibly high rate. Blue, visible and infrared filters, as well as a filter that isolates hydrogen emission, were used by Hubble’s Wide Field Planetary Camera 2 to capture the shot. Because of this, the blue knots in these two galaxies indicate the growth of new stars, highlighted by the presence of hydrogen.
Older yellowish stars can be seen in the centers of each galaxy.
Arp 274 was previously been photographed with less detail, and was featured as NASA's Image Of The Day.
Recently, an image was presented of two galaxies colliding to form what appeared to be an exclamation point in Space.
