This Hubble image shows NGC 4907, a barred spiral galaxy located 284 million light-years away in the constellation of Coma Berenices. The image is a composite of separate exposures acquired by Hubble’s Wide Field Camera 3 (WFC3). Two filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / M. Gregg.

This two-panel illustration shows a black hole surrounded by a disk of gas, before and after the disk is partially dispersed. In the left panel, the ball of white light above the black hole is the black hole corona, a collection of ultra-hot gas particles that forms as gas from the disk falls into the black hole. The streak of debris falling toward the disk is what remains of a star that was torn apart by the black hole’s gravity. The right panel shows the black hole after the debris from the star has dispersed some of the gas in the disk, causing the corona to disappear. Image credit: NASA / JPL-Caltech.

A high-resolution image from the Extreme Ultraviolet Imager (EUI) on Solar Orbiter, taken with the HRIEUV telescope on May 30, 2020. The circle in the lower left corner indicates the size of Earth for scale. The arrow points to one of the ubiquitous features of the solar surface, called ‘campfires’ and revealed for the first time by these images. On May 30, Solar Orbiter was roughly halfway between the Earth and the Sun, meaning that it was closer to the Sun than any other solar telescope has ever been before.

An artist’s impression of a thermonuclear supernova: the material ejected by the supernova will initially expand very rapidly, but then gradually slow down, forming an intricate giant bubble of hot glowing gas; eventually, the charred remains of the white dwarf that exploded will overtake these gaseous layers, and speed out onto its journey across our Milky Way Galaxy.
