Using the shadows of clusters to measure the universe

Astronomers have begun using a sophisticated suite of simulations, an advanced machine learning model of the formation of galaxy clusters, and an exotic relationship between galaxies to understand the origins of dark matter ...

Thirteen new pulsars discovered with MeerKAT

Using the MeerKAT radio telescope, astronomers from the Max Planck Institute for Radio Astronomy (MPIfR) in Bonn, Germany and elsewhere, have detected 13 new pulsars in the globular cluster Omega Centauri. The finding was ...

Astronomers begin to understand strange 'backsplash' galaxies

Clusters of galaxies do not appear in an instant. Instead they gradually form through the accumulation of many galaxies. But when galaxies fall in they don't just stop moving. Instead, they keep moving around. These are called ...

A true view of infant star clusters

Super star clusters (SSCs) are dense clusters of bright young stars. As they evolve their intense radiation can clear gas and dust from their region. But as they are forming the region around them is still undisturbed. Because ...

Webb uncovers star formation in cluster's dusty ribbons

NGC 346, one of the most dynamic star-forming regions in nearby galaxies, is full of mystery. Now, though, it is less mysterious thanks to new findings from the NASA/ESA/CSA James Webb Space Telescope.

Blue straggler stars are weird

All stars follow a particular path in their lives once they start fusing hydrogen. As they live they steadily get brighter and hotter until they turn to fusing other elements. Every star follows this exact same path…except ...
