This illustration plots changes in the brightness of Betelgeuse, following the titanic mass ejection of a large piece of its visible surface; the escaping material cooled to form a cloud of dust that temporarily made the star look dimmer, as seen from Earth; this unprecedented stellar convulsion disrupted the monster star’s 400-day-long oscillation period that astronomers had measured for more than 200 years; the interior may now be jiggling like a plate of gelatin dessert.

In this multiwavelength view, radio emission from SNR G106.3+2.7 is blue and green, while yellow, orange, and red reveal radio waves from a vast cloud of interstellar gas; at center, the pink region shows where protons boosted by the supernova’s shock wave strike the gas, emitting a tell-tale glow of gamma rays.

This Hubble image shows three galaxies LEDA 58109, SDSS J162558.14+435746.4, and SDSS J162557.25+435743.5. The color image is composed of infrared, optical and ultraviolet observations from Hubble’s Advanced Camera for Surveys (ACS), the Dark Energy Camera (DECam) on the Victor M. Blanco 4-m Telescope, and the Sloan Digital Sky Survey (SDSS). Nine 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 / W. Keel.
