NASA Hubble's top images showcase a forming protostar, Arctic sea ice patterns, a dying star's planetary nebula, the ancient ...

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.

Jamie Carter is an award-winning reporter who covers the night sky. Globular clusters like this one, Omega Centauri, are very dense groupings of up to a million stars ... [+] in a sphere ...

Why are open star clusters in the disk of a spiral galaxy, while globulars are in the halo? Is the same true for irregular ...

The constellation Hercules contains two of the finest globular star clusters visible in the Northern Hemisphere: M13 (below) and M92 (not shown -- yet!). Each contains several hundred thousand stars, ...

Another possibility is that J1249+36 existed in a globular cluster, or a spherically shaped, closely bound grouping of stars. Astronomers predict that black holes with different masses exist at ...

Use the lowest-power eyepiece you have. A little-observed cluster Our large-telescope target is a celestial object from a little-known catalog — globular cluster Palomar 12 in Capricornus.

ABSTRACT Globular clusters are ideal laboratories to study the evolution of low‐mass stars. In this work we concentrate on three types of hot stars observed in globular clusters: horizontal branch ...

Globular clusters are spherical, densely packed groups of stars found around galaxies. They are thought to have formed at the same time as their host galaxy and thus provide a powerful probe for ...
