This artist’s illustration portrays what the gravitationally lensed galaxy SGAS 1110 might look like up close. A sea of young, blue stars is streaked with dark dust lanes and studded with bright pink patches that mark sites of star formation. SGAS 1110 is one of more than 70 studied as part of the Sloan Giant Arcs Survey, an imaging survey that searched 240 galaxy clusters to find new examples of gravitational lensing.

This artist’s concept shows what the young, ‘dead,’ disk galaxy MACS 2129-1 (right) would look like when compared with our Milky Way Galaxy (left). Although three times as massive as the Milky Way, it is only half the size. MACS 2129-1 is also spinning more than twice as fast as the Milky Way. Note that regions of the Milky Way are blue from bursts of star formation, while MACS 2129-1 is yellow, signifying an older star population and no new star birth. Image credit: NASA / ESA / Z. Levy, STScI.

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 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.
