The Stickney Crater is the largest crater on the Martian Moon Phobos. Stickney is nearly half the diameter of the moon itself. The event that caused this crater seems to have almost destroyed the small moon. This image was taken by the HiRISE camera aboard the Mars Reconnaissance Orbiter. The streaks along Phobos suggest that material has slid inside the crater walls over time. The actual event that caused this crater is unknown.

4.1 The N44 Complex
The N44 complex is about 1,000 light-years across and is a grouping of several emission nebulae. It can only be seen in the Southern hemisphere, located in Large Magellanic cloud, our neighboring galaxy. The stellar winds and heat given off from highly luminous stars sculpt the glowing nebular gas into unique shapes. Supernovae have also contributed to the complex's unique shape.
