A quarter of all galaxies are irregular, meaning they don’t appear in a standard, recognizable way. This galaxy, known as NGC 2337, located 25 million light-years away in the Lynx constellation, is irregular, offering astronomers a way to learn about how galaxies evolve and interact.

Known as Messier 18, the open cluster of blue stars in the upper left of this photo formed together from the same gas and dust cloud, providing an ideal example for studying the lifecycle of stars. The VLT Survey Telescope at ESO’s Paranal Observatory in Chile took this photo of Messier 18 and the surrounding red hydrogen clouds.

This image of clouds in Saturn’s northern hemisphere is a composite of photos taken by NASA’s Cassini spacecraft, using filters sensitive to infrared light. These spectral filters help show the depth and shape of clouds.

This week, two small galaxies, Pisces A and B, made it out of the Local Void, an isolated area, into a highly populated part of the cosmos. NASA’s Hubble Space Telescope captured new stars in the two galaxies, documenting new growth after billions of years.

The top of this image shows smooth plains on Mars’ surface, and the center shows a flat area between two craters which Schiaparelli, the ExoMars Entry, Descent and Landing Demonstrator Module, will target. The bottom of the image shows channels carved by water long ago.

The Rosetta mission captured this photo of Comet 67P/Churyumov-Gerasimenko while eight miles from the center of the comet.

Titan, one of Saturn’s moons, has deep, steep canyons, as documented in this photo from NASA’s Cassini spacecraft—the same canyon carvings found along Arizona’s Colorado River. These canyons are flooded with liquid hydrocarbons, providing evidence of channels of liquid on Titan.

On Friday, August 12, a meteor raced across the sky during the Perseid shower, as Earth annually crosses debris left by an ancient comet. This 30-second exposure taken in Spruce Knob, West Virginia captures its flight.
