Hubble Sees Strange Result of Recent Galactic Collision

This image of the irregular galaxy NGC 4485 was made from separate exposures taken in the visible region of the spectrum with Hubble’s Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys (ACS). NGC 4485 has been involved in a dramatic gravitational interplay with its larger galactic neighbor, NGC 4490, out of frame to the bottom right in this image. This ruined the original, ordered spiral structure of the galaxy and transformed it into an irregular one. Below NGC 4485 one can see a bright, orange background galaxy: CXOU J123033.6+414057. This galaxy is the source of X-ray radiation studied by NASA’s Chandra X-ray Observatory. It’s distance from Earth is about 850 million light-years. Image credit: NASA / ESA / Hubble.

The NASA/ESA Hubble Space Telescope has produced a beautiful image of NGC 4485, an irregular galaxy located in the constellation Canes Venatici, about 30 million light-years away from Earth. NGC 4485 shows all the signs of having been involved in a hit-and-run accident with a bypassing galaxy, NGC 4490; rather than destroying NGC 4485, the chance encounter is spawning a new generation of stars. This image of the irregular galaxy NGC 4485 was made...

Astronomers developed a mosaic of the distant Universe -- called the Hubble Legacy Field -- that documents 16 years of observations from the NASA/ESA Hubble Space Telescope. The image contains nearly 265,000 galaxies that stretch back through 13.3 billion years of time to just 500 million years after the Big Bang. The new set of Hubble images, created from nearly 7,500 individual exposures, is the first in a series of Hubble Legacy Field images. Image credit: NASA / ESA / G. Illingworth & D.
