The NASA/ESA Hubble Space Telescope has identified thousands of more than 5 billion years old globular clusters in the Virgo cluster of galaxies. One of the results of these discoveries led ...

Using data from the Magellan Clay telescope and the Canada-France-Hawaii Telescope (CFHT), astronomers have investigated a ...

A globular cluster is a spherical collection of stars. Globular clusters are very tightly bound by gravity, giving them their spherical shapes and high concentrations of stars toward their centers.

A glittering multitude of stars in the globular cluster Terzan 4 fills this image from the NASA/ESA Hubble Space Telescope. Globular clusters are collections of stars bound together by their mutual ...

The first time I heard about galaxies without dark matter, I was sitting in my very first graduate class at the University of ...

The globular cluster Terzan 2 in the constellation Scorpio is featured in this observation from the NASA/ESA Hubble Space Telescope. Globular clusters are stable, tightly gravitationally bound ...

It seems like the only things I have seen in the evening sky recently have been clouds. Although the garden plants are happy with the rain, my dogs are unhappy about the thunder. Whenever the sky does ...
