SN 2021yfj is a new kind of supernova, challenging our understanding of stellar evolution. Its progenitor lost its outer shells well before the supernova happened and only consisted of its oxygen/silicon core — unlike any known star in the Milky Way. The dying, stripped-to-the-bone star experienced extreme mass loss episodes that led to the ejecting of material rich in silicon (grey), sulfur (yellow) and argon (purple).

A study led by the Center for Astrophysics | Harvard & Smithsonian (CfA) has captured the explosive interaction between a black hole and a nearby massive star (blue), as depicted in this artist's conception. As the separation between the star and the black hole decreased, the black hole's intense gravity pulled gas and dust off of the star into a disk. Before the star was able to swallow the black hole, gravitational stress from the black hole triggered the star's explosion. Collisions between the stellar explosion and shells of material from earlier interactions located above and below the disk powered a dramatic re-brightening event. This artist’s graphic shows the massive star and black hole before the supernova explosion, when the star’s shape is stretched by gravitational forces from the black hole. Credit: Melissa Weiss/CfA

This artist’s concept visualizes a kilonova – an explosion that happens when two neutron stars or a neutron star and a black hole collide and merge. When these collisions happen, a fraction of the resulting debris is ejected as jets, which move near the speed of light. The remaining debris produces hot, glowing, neutron-rich clouds that forge heavy elements, like gold and platinum. Researchers will mine data from NASA’s Nancy Grace Roman Space Telescope, which will survey the same areas of the sky every few days, to identify kilonovae. Roman’s extensive data will help astronomers better identify how often these events occur, how much energy they give off, and how near or far they are.

A bright disc of purplish, white and gold lines surrounds a black ellipse-shaped area, that looks like a hole in space. A ball of shining material pierces through the disc; an eruption of bright white-to-gold rays encircles the small hole in the disc provoked by the passage of the shining ball

The Giant Metrewave Radio Telescope imaged these giant radio jets stretching 6 million light-years across with an enormous supermassive black hole at the heart of spiral galaxy J23453268-0449256. Could this cosmic anomaly hint at the future of our own Milky Way galaxy? Image via Bagchi and Ray et al/ Giant Metrewave Radio Telescope/ Royal Astronomical Society/

This collage highlights a small selection of regions of the Milky Way imaged as part of the most detailed infrared map ever of our galaxy. Here we see, from left to right and top to bottom: NGC 3576, NGC 6357, Messier 17, NGC 6188, Messier 22 and NGC 3603. All of them are clouds of gas and dust where stars are forming, except Messier 22, which is a very dense group of old stars.

This artist's concept illustrates a supermassive black hole with millions to billions times the mass of our sun. Supermassive black holes are enormously dense objects buried at the hearts of galaxies.
