Analysing Dusty Debris Around the Star Fomalhaut

the rings of dusty debris around the star

This image of the dusty debris disk surrounding the young star Fomalhaut is from Webb’s Mid-Infrared Instrument (MIRI). It reveals three nested belts extending out to 14 billion miles (23 billion kilometers) from the star. The inner belts – which had never been seen before – were revealed by Webb for the first time.

Detecting Very Compact Star Clusters

“The galaxy clusters we examined are so massive that they bend light rays passing through their centre, as predicted by Einstein in 1915. And this in turn produces a kind of magnifying glass effect: the images of background galaxies are magnified.” Adélaïde Claeyssens, Department of Astronomy, Stockholm University
