Initially, the astronomer who first made note of this fuzzy-looking glowing cluster thought it might be a nebula. But it’s not. M3 is what’s called a globular cluster. Scientists believe it ...

You will identify a luminous ball of old stars huddled together like a densely packed cluster of cosmic fireflies. Known as the globular cluster, it is making its unique nighttime spectacle in five ...

At its best in July is this famous globular cluster — a dense ball of as many as half a million ancient stars that are almost as old as the universe itself. Also called M13 and appearing as a ...

May is when we’ll have opportunities to see a meteor shower, the flower moon, 2 globular star clusters, and a small alignment. Up first is the ETA Aquarids meteor shower. This meteor shower ...

Japanese astronomers have presented new results of observations that suggest an unidentified X-ray source designated AX J145732−5901 is a cluster of galaxies behind the galactic plane.

One kind, called open clusters, can have thousands of stars in them. Globular star clusters, on the other hand, can host tens of millions of stars that total up to several million times the mass ...

The treatment is administered subcutaneously into the skin of the middle thigh. The Food and Drug Administration (FDA) has approved Brekiya ® (dihydroergotamine mesylate) injection for the acute ...
