An artist's impression of Japan’s Hayabusa2 space mission touching down on the surface of the asteroid 1998 KY26. New observations with ESO’s Very Large Telescope (VLT) have revealed that 1998 KY26 is just 11 m wide, almost three times smaller than previously thought, and is spinning once every 5 minutes, which is much faster than expected. The image above shows an updated size comparison between the asteroid and spacecraft.

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).

This image of Uranus from NIRCam (Near-Infrared Camera) on NASA's James Webb Space Telescope exquisitely captures Uranus's seasonal north polar cap and dim inner and outer rings. This Webb image also shows 9 of the planet's 27 moons – clockwise starting at 2 o'clock, they are: Rosalind, Puck, Belinda, Desdemona, Cressida, Bianca, Portia, Juliet, and Perdita.

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.

This is HOPS-315, a baby star where astronomers have observed evidence for the earliest stages of planet formation. These observations show that hot minerals are beginning to solidify. In orange we see the distribution of carbon monoxide, blowing away from the star in a butterfly-shaped wind. In blue we see a narrow jet of silicon monoxide, also beaming away from the star. These gaseous winds and jets are common around baby stars like HOPS-315.

In this artist's impression we see the planet HIP 67522 b sending a wave of energy down the magnetic field lines towards the surface of its host star. Where the wave meets the end of the magnetic field line at the star's surface, it triggers a massive flare. Credit: Danielle Futselaar (www.artsource.nl/)
