Astronomers have discovered that the next target for Japan’s Hayabusa2 spacecraft, the asteroid 1998 KY26, is almost three times smaller than previously thought, and spinning much faster than expected. This study was conducted using ESO’s Very Large Telescope, and its results offer important new information for the upcoming mission, just six years out from the spacecraft’s encounter with this tiny asteroid.

What lies behind this chaotic extravaganza? This video takes you on a journey across the star cluster RCW 38, located 5500 light-years from us.

Two stars have been found orbiting each other in the vicinity of Sgr A*, the supermassive black hole at the centre of the Milky Way. A young binary star system forming and surviving in this extreme gravity means that black holes are not as destructive as we thought. This video summarises the discovery.

Thanks to ESO’s Very Large Telescope Interferometer, astronomers have taken the first close-up picture of a star outside our galaxy, more than 160 000 light-years from us. The star is surrounded by a giant cocoon of dust, revealing it is in the last stages before becoming a supernova. This video summarises the discovery.
