Astronomers have discovered a new post-asymptotic giant branch (PAGB) star in a Galactic globular cluster known as ESO 37-1 (or E3 for short) and derived its fundamental parameters. The finding is reported in a research paper ...
Using the Hubble Space Telescope (HST), astronomers have investigated the stellar population of the globular cluster NGC 1835. They detected a remarkably extended horizontal branch in this system. The discovery, reported ...
This densely populated group of stars is the globular cluster NGC 1841, which is part of the Large Magellanic Cloud (LMC), a satellite galaxy of our Milky Way galaxy that lies about 162,000 light-years away. Satellite galaxies ...

Using NASA's Chandra X-ray spacecraft, astronomers have inspected a potential super-star cluster, designated HSO BMHERICC J72.971176-69.391112, or H72.97−69.39 for short. The new observations resulted in the detection of ...
The gigantic galaxies we see in the universe today, including our own Milky Way galaxy, started out far smaller. Mergers throughout the universe's 13.7 billion years gradually assembled today's massive galaxies. But they ...
