Two newly discovered globular clusters have been added to the total of just 158 known globular clusters in our Milky Way. They were found in new images from the European Southern Observatory’s (ESO) ...

A stronomers report the discovery of a truly incredible object. They are calling it Candidate Dark Galaxy-2 (CDG-2), a ...

Astronomers measure stellar masses in terms of the Sun’s mass (just shy of 4.4 quadrillion quadrillion pounds [2.0 quadrillion quadrillion kilograms]). Most stars in globular clusters today are less ...

Hubble recently captured a dazzling image of the heart of globular cluster Terzan 9, a bright ball of stars 23,000 light years away. Globular clusters are tightly packed groups of tens of thousands — ...

A globular cluster is a spherical collection of stars that orbits a galactic core as a satellite. Globular clusters are very tightly bound by gravity, which gives them their spherical shapes and ...

A galaxy made of 99.94% to 99.98% dark matter immediately challenges and updates models for how dark matter works. It also sheds light on how the universe arrived at the large-sca ...

Stars shine like diamonds in this week’s image from the Hubble Space Telescope, which shows globular cluster Terzan 9. Located in the constellation of Sagittarius, Terzan 9 is relatively close to the ...

This week’s image from the Hubble Space Telescope shows a sparkling collection of thousands of stars. One formation commonly seen within galaxies is called a globular cluster, in which thousands of ...

Globular star clusters are extraordinary in almost every way. They're densely packed, holding a million stars in a ball only about 100 light-years across on average. They're old, dating back almost to ...
