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.

This thrust fault is one of thousands discovered on the Moon by NASA’s Lunar Reconnaissance Orbiter. These faults resemble small stair-shaped cliffs, or scarps, when seen from the lunar surface. The scarps form when one section of the Moon’s crust (left-pointing arrows) is pushed up over an adjacent section (right-pointing arrows) as the Moon’s interior cools and shrinks.
