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.

Composite image of the Boomerang Nebula: ALMA observations (orange) showing the hourglass-shaped outflow, which is embedded inside a roughly round ultra-cold outflow; the hourglass outflow stretches more than 1.9 trillion miles from end to end, and is the result of a jet that is being fired by the central star, sweeping up the inner regions of the ultra-cold outflow like a snow-plow; the ultra-cold outflow is about 10 times bigger. The ALMA data are shown on top of an image from the NASA/ESA Hubble Space Telescope (blue). Image credit: ALMA / ESO / NAOJ / NRAO / NASA / ESA / Hubble / AUI / NSF.

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.

Composite image of the Fomalhaut star system. The ALMA data, shown in orange, reveal the distant and eccentric debris disk in never-before-seen detail. The central dot is the unresolved emission from the star, which is about twice the mass of our Sun. Optical data from the NASA/ESA Hubble Space Telescope is in blue; the dark region is a coronagraphic mask, which filtered out the otherwise overwhelming light of the central star.
