Astronomers with the COSMOS-Web collaboration have identified a ghostly object AzTECC71 as a dusty star-forming galaxy. Or, in other words, a galaxy that’s busy forming many new stars but is shrouded in […]
10,000 citizen astronomers have helped classify galaxies in data from the Subaru Telescope as part of the citizen science project GALAXY CRUISE The first scientific paper produced from the project shows unambiguously […]
The big galaxy in the foreground is named LEDA 2046648, and is seen just over a billion years back in time, while most of the others lie even farther away, and hence are seen even further back in time. Image credit: ESA/Webb, NASA & CSA, A. Martel.
“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
The researchers studied the Sparkler galaxy located in Webb’s First Deep Field and used JWST to determine that five of the sparkling objects around it are globular clusters. Image credit: Canadian Space Agency with images from NASA, ESA, CSA, STScI; Mowla, Iyer et al. 2022.
