Hubble Snaps Stunning Image of Wolf-Rayet Star

The Wide Field and Planetary Camera 2 on the NASA/ESA Hubble Space Telescope has taken a beautiful image of a Wolf-Rayet star surrounded by a nebula of...

These Hubble images show elliptical galaxies with dark, wispy dust lanes, the signature of a recent galaxy merger. The dust is the only relic of a smaller galaxy that was consumed by the larger elliptical galaxy. The X in the images marks the location of supernova explosions that are associated with the galaxies. Each supernova may have been gravitationally kicked out of its host galaxy by a pair of central supermassive black holes. When two galaxies merge, so do their supermassive black holes. Prof Foley suggests the supernovae were stars that were once part of double-star systems. These systems wandered too close to the binary black holes, which ejected them from their galaxies. Eventually, the stars in each system moved close enough together to trigger a supernova blast. These outcast supernovae are located at various distances from their home galaxies. SN 2000ds (left) is at least 12,000 light-years from its galaxy, NGC 2768; SN 2005cz (right) is at least 7,000 light-years from its galaxy, NGC 4589. NGC 2768 resides 75 million light-years from Earth, and NGC 4589 is 108 million light-years away. Image credit: NASA / ESA / R. Foley, University of Illinois.

Reddish streaks cut across the surface of Tethys in this image. The streaks are narrow, curved lines on the moon’s surface, only a few miles wide but several hundred miles long. The yellowish tones on the left side of the view are a result of alteration of the moon’s surface by high-energy particles from Saturn’s magnetosphere. This particle radiation slams into the moon’s trailing hemisphere, modifying it chemically and changing its appearance in enhanced-color views like this one. The area of Tethys shown here is centered on 30 degrees north latitude, 187 degrees west longitude, and measures 305 by 258 miles (490 by 415 km) across. The original color images were obtained at a resolution of about 2,300 feet (700 m) per pixel on April 11, 2015. Image credit: NASA / JPL-Caltech / Space Science Institute.
