Using observations of Centaurus A, a nearby elliptical galaxy, obtained with the Gaia space telescope and ground-based instruments under the PISCeS survey, a team of astronomers presents an ...

The Chandra image of the Centaurus galaxy cluster shows a long plume-like feature resembling a twisted sheet. The plume is some 70,000 light years in length and has a temperature of about 10 million ...

The Centaurus Cluster is a collection of hundreds of galaxies located about 145 million light years from Earth. At the center of the cluster is a large elliptical galaxy called NGC 4696. Buried within ...

A huge catalogue of 40,000 previously unknown globular clusters—mysterious clumps of ancient stars —has been revealed around the closest elliptical galaxy to us. Presented to the Astronomical Society ...

A survey completed using a combination of ground and space-based telescopes yielded a treasure trove of previously unknown globular clusters – old, dense groups of thousands of stars that all formed ...
