Study inspects galaxy protocluster PHz G237.01+42.50

An international team of astronomers has performed spectroscopic observations of a distant galaxy protocluster known as PHz G237.01+42.50. Results of the study, presented in a paper published September 9 on the arXiv pre-print ...

Rerun of supernova blast expected to appear in 2037

It's challenging to make predictions, especially in astronomy. There are however, a few forecasts astronomers can depend on, such as the timing of upcoming lunar and solar eclipses and the clockwork return of some comets.

Galaxy cluster Abell 3158 inspected in X-rays

Astronomers from the University of Bonn, Germany and elsewhere have used the eROSITA telescope onboard the Spektrum-Roentgen-Gamma (SRG) mission to perform X-rays observations of a nearby galaxy cluster known as Abell 3158. ...

Dozens of ultra-compact dwarf galaxies detected

Astronomers from the University of Groningen and elsewhere have identified 44 new ultra-compact dwarf galaxies (UCDs). The newly found objects most likely belong to the Fornax Cluster. The discovery is reported in a paper ...

Dark Energy Survey physicists open new window into dark energy

The universe is expanding at an ever-increasing rate, and while no one is sure why, researchers with the Dark Energy Survey (DES) at least had a strategy for figuring it out: They would combine measurements of the distribution ...
