Using the MeerKAT radio telescope array, an international team of astronomers has detected eight new millisecond pulsars. The newfound objects are located in six globular clusters. The finding is reported in a paper published ...
Radio telescopes are the world's most sensitive radio receivers, capable of finding extremely faint wisps of radio emission coming from objects at the farthest reaches of the universe. Recently, a team of astronomers used ...

Using Very Large Telescope (VLT) and Atacama Large Millimeter/submillimeter Array (ALMA), researchers from the University of Vienna, Austria, and elsewhere have investigated the brightest cluster galaxy (BCG) in a massive ...
Indian researchers have carried out ultraviolet photometric observations of an old open cluster known as NGC 188. Results of the study, conducted with the AstroSat spacecraft, provide important information about stellar populations ...
Astronomers have performed spectroscopic observations of a globular cluster (GC) known as Djorgovski 2 and obtained chemical abundances of the cluster's seven stars. The results suggest that Djorgovski 2 contains multiple ...
At present, the formation of galaxies is difficult to understand without the presence of a ubiquitous, but mysterious component, termed dark matter. Astronomers have measure how much dark matter there is around galaxies, ...
