A galactic smile. In the center of this Hubble image are two faint galaxies that seem to be smiling. You can make out two orange eyes and a white button nose. In the case of this “happy face,” the two eyes are the galaxies SDSSCGB 8842.3 and SDSSCGB 8842.4, and the misleading smile lines are actually arcs caused by an effect known as strong gravitational lensing, distorting light from more distant objects.
Ring of New Stars in Edge-On Galaxy NGC 4013 | After more than three years of inactivity, and thanks to a new cryogenic refrigerator, the Hubble Space Telescope's Near Infrared Camera and Multi-Object Spectrometer (NICMOS) today debuts various breathtaking views...
Eta Carinae's great eruption in the 1840s created the billowing Homunculus Nebula, imaged here by Hubble, and transformed the binary into a unique object in our galaxy. Astronomers cannot yet explain what caused this eruption. The discovery of likely Eta Carinae twins in other galaxies will help scientists better understand this brief phase in the life of a massive star.

The Tadpole Galaxy (also known as UGC 10214 or Arp 188) is a disrupted barred spiral galaxy located about 420 million light-years away toward the northern constellation Draco. Its most dramatic features are an incredibly long trail of stars and massive, bright blue star clusters, reflecting the essence of our dynamic, restless and violent Universe. - Credit: NASA, Hubble, Mehdi Bozzo-Rey
