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.

An artist’s impression of a white dwarf star (left) in orbit around a black hole and so close that much of its material is being pulled away. There is a hotspot where the gas from the white dwarf hits the disc of matter swirling around the black hole. The black hole itself is surrounded by a cloud of ionized gas, which contains large amounts of oxygen. Image credit: NASA / CXC / M. Weiss.

This Hubble image shows the remnant of SN 1987A within the Large Magellanic Cloud, a satellite galaxy of the Milky Way. The image was taken by Hubble’s Wide Field Camera 3 (WFC3) in January 2017. SN 1987A is located in the center of the image amidst a backdrop of stars. The bright ring around the central region of the exploded star is composed of material ejected by the star about 20,000 years before the actual explosion took place. The supernova is surrounded by gaseous clouds. The clouds’ red color represents the glow of hydrogen gas. The colors of the foreground and background stars were added from observations taken by Hubble’s Wide Field Planetary Camera 2 (WFPC2). Image credit: NASA / ESA / R. Kirshner, Harvard-Smithsonian Center for Astrophysics and Gordon and Betty Moore Foundation / P. Challis, Harvard-Smithsonian Center for Astrophysics.
