The giant elliptical galaxy in the center of this Hubble image is the most massive and brightest member of the galaxy cluster Abell 2261. Spanning a little more than one million light-years, the galaxy is about 10 times the diameter of the Milky Way Galaxy. Abell 2261 is located approximately 3 billion light-years away.

Stein 2051B Shows How Gravity Can Bend Starlight

This illustration reveals how the gravitation of the white dwarf Stein 2051B warps space and bends the light of a distant star behind it. The NASA/ESA Hubble Space Telescope captured images of Stein 2051B as it passed in front of the background star. During the close alignment, Stein 2051B deflected the starlight, which appeared offset by about 2 milli-arcseconds from its actual position. From this measurement, astronomers calculated that the white dwarf’s mass is roughly 68% of the Sun’s mass. Image credit: NASA / ESA / A. Field, STScI.

This Pluto mosaic was made from New Horizons LORRI images taken on July 14, 2015, from a distance of 49,700 miles (80,000 km). This view is projected from a point 1,118 miles (1,800 km) above Pluto’s equator, looking northeast over the dark, cratered Cthulhu Regio toward the bright, smooth expanse of icy plains called Sputnik Planum. Pluto’s North Pole is off the image to the left. This mosaic was produced with panchromatic images from the New Horizons LORRI camera, with color overlaid from the Ralph color mapper onboard New Horizons. Image credit: S.A. Stern et al.

$This enhanced-color view of Enceladus is largely of the southern hemisphere and includes the south polar terrain at the bottom of the image. Ancient craters remain somewhat pristine in some locales, but have clearly relaxed in others. Northward-trending fractures, likely caused by a change in the moon’s rate of rotation and the consequent flattening of the moon’s shape, rip across the southern hemisphere. The south polar terrain is marked by a striking set of ‘blue’ fractures and encircled by a conspicuous and continuous chain of folds and ridges, testament to the forces within Enceladus that have yet to be silenced. The mosaic was created from 21 false-color frames taken during Cassini’s close approaches to Enceladus on March 9 and July 14, 2005. Images taken using filters sensitive to UV, visible and IR light (spanning wavelengths from 338 to 930 nm) were combined to create the individual frames.

$Pale zones called ‘halos’ border bedrock fractures visible in this 2015 image (colorized) from the Curiosity rover. Measurements overlaid on the image offer a sense of scale for the size of these fractures. The rover team determined that the halos are rich in silica, a clue to the duration of wet environmental conditions long ago. Image credit: NASA / JPL-Caltech.$

The huge storm churning through the atmosphere in Saturn’s northern hemisphere overtakes itself as it encircles the planet in this true-color view from NASA’s Cassini spacecraft. This picture, captured on Feb. 25, 2011, was taken about 12 weeks after the storm began, and the clouds by this time had formed a tail that wrapped around the planet. Some of the clouds moved south and got caught up in a current that flows to the east (to the right) relative to the storm head. This tail, which appears as slightly blue clouds south and west (left) of the storm head, can be seen encountering the storm head in this view. This storm is the largest, most intense storm observed on Saturn by NASA’s Voyager or Cassini spacecraft. It is still active today. As scientists have tracked this storm over several months, they have found it covers 500 times the area of the largest of the southern hemisphere storms observed earlier in the Cassini mission. The shadow cast by Saturn’s rings has a strong seasonal effect, and it is possible that the switch to powerful storms now being located in the northern hemisphere is related to the change of seasons after the planet’s August 2009 equinox.

This pair of visible-light and near-infrared Hubble photos shows N6946-BH1 before and after it vanished out of sight by imploding to form a black hole. The left image shows the star as it looked in 2007. In 2009, the star shot up in brightness to become over 1 million times more luminous than our Sun for several months. But then it seemed to vanish, as seen in the right panel image from 2015. A small amount of IR light has been detected from where the star used to be. This radiation probably comes from debris falling onto a black hole. Image credit: NASA / ESA / C. Kochanek, Ohio State University.
