Using the MeerKAT radio telescope, an international team of astronomers has detected 13 new pulsars in the globular cluster NGC 1851. Twelve of them turned out to be millisecond pulsars (MSPs). The discovery was reported ...
Using India's AstroSat spacecraft, astronomers have inspected ultraviolet (UV) bright sources in a globular cluster known as NGC 4590 and identified more than 1,400 stellar objects presenting various evolutionary status. ...
University of Notre Dame researchers, along with collaborators in China and Australia, published a new sample catalog of more than 24 million stars that can be used to decipher the chemical history of elements in the Milky ...

Using the Hubble Space Telescope (HST), astronomers have observed the globular cluster Messier 14 and its peculiar multiple stellar populations. Results of the observational campaign, published January 7 on arXiv.org, deliver ...
Astronomers know that the Milky Way grew by taking in smaller galaxies. But now, a team of Italian-Dutch researchers has shown that a small galaxy neighboring the Milky Way has in turn absorbed an even smaller galaxy from ...

An international team of astronomers has conducted a detailed study of a globular cluster known as Palomar 6 (or Pal 6 for short). Results of the research could help us better understand the nature of this cluster. The study ...
This star-studded image from the NASA/ESA Hubble Space Telescope depicts NGC 6717, which lies more than 20,000 light-years from Earth in the constellation Sagittarius. NGC 6717 is a globular cluster, a roughly spherical collection ...
