We know that a star’s childhood is turbulent: growing via a disc of gas and dust, the same disc from which planets form. Young stars also experience outbursts, expelling material via fast jets that regulate how much material is left to feed the young stars and form planets around it. Today’s...
Creating a star is hard work, and the process is not very efficient. Current knowledge suggests that a stellar nursery must have a minimum density of gas and dust for a star to form. Only 1-2% of all the gas and dust in these clouds is utilised to ignite a star. But could even denser regions be...
VLT image of a dead star creating a shock wave as it moves through space
The central square image, taken with the MUSE instrument on ESO’s Very Large Telescope, shows shock waves around the dead star RXJ0528+2838. When a star moves through space it can push away nearby material creating a so-called bow shock, which in this image is glowing in red, green and blue....
The low-surface-brightness galaxy CDG-2, shown in this image from the NASA/ESA Hubble Space Telescope, is dominated by dark matter and contains only a sparse scattering of stars. This galaxy is nearly invisible, but by using advanced statistical techniques, scientists identified it by searching...
This newly processed image from the NASA/ESA Hubble Space Telescope is the clearest view yet of the Egg Nebula. It is a preplanetary nebula, a structure of gas and dust created as a Sun-like star approaches the end of its life. The Egg that we see now will eventually hatch, revealing a white...
For this Picture of the Month from the NASA/ESA Hubble Space Telescope, we have a sight of an uncommon galaxy with a striking appearance. This is NGC 7722, a lenticular galaxy located about 187 million light-years away in the constellation Pegasus. A “lenticular”, meaning “lens-shaped”, galaxy...

This is a previously-undiscovered astrophysical anomaly, found in the Hubble Space Telescope’s archive by researchers using a new AI-assisted method. The AI tool allowed them to sift through nearly 100 million image cutouts in just days, turning up rare and anomalous objects like this one. This...
