This is an artist's impression of the SN 1987A remnant. The image is based on real data and reveals the cold, inner regions of the remnant, in red, where tremendous amounts of dust were detected and imaged by ALMA. This inner region is contrasted with the outer shell, lacy white and blue circles, where the blast wave from the supernova is colliding with the envelope of gas ejected from the star prior to its powerful detonation.

This artist impression shows ultra-fast winds blasting out from the center of galaxy Markarian 817. These winds, moving at many millions of km per hour, clear out interstellar gas from a vast region of space. Without this gas, the galaxy can’t form new stars and the black hole in the galactic center has little left to eat. The inset shows what is happening at galaxy’s heart. A supermassive black hole draws in gas from its surroundings, which forms a hot, brightly lit accretion disk (orange). The cause of the winds (white) is magnetic fields within the disk, which fling particles out in all directions at incredibly high speeds. These winds effectively block out X-rays (blue) which are sent out by the extremely hot plasma surrounding the black hole, called the corona. Zak et al. caught Markarian 817 blasting out ultra-fast winds using ESA’s X-ray telescope XMM-Newton. Lasting for around a year, the winds will have significantly affected star formation in the galaxy. The fact that the black hole at the center of the galaxy was showing rather average activity levels before producing the winds suggests that ultra-fast black hole winds are much more common than previously thought. In other words, black holes and their host galaxies strongly affect each other’s evolution. Image credit: ESA / CC BY-SA 3.0 IGO.
