During the late 18th century, Charles Messier began to notice a series of "nebulous" objects in the night sky which he originally mistook for comets. With the hope of preventing other astronomers from making the same mistake, ...

When our galaxy was born, around 13,000 million years ago, a plethora of clusters containing millions of stars emerged. But over time, they have been disappearing. However, hidden behind younger stars that were formed later, ...

(Phys.org)—When a giant cloud of molecular gas condenses, star clusters are born. It may sound simple but the formation of star clusters is a very complex process, not yet completely understood by scientists. By peering ...
Shown here in a new image taken with the Advanced Camera for Surveys (ACS) on board the NASA/ESA Hubble Space Telescope is the globular cluster NGC 1783. This is one of the biggest globular clusters in the Large Magellanic ...

A supernova explosion at the end of a large star's life can leave the collapsed core, or neutron star, hurtling away from its dust and gas envelope at hundreds of kilometres per second. Now, astronomers have found that even ...
