• Bound together by gravity
• House an impressive range of stars

Navigating the Cosmos to M15

The M15 Globular Cluster is a radiant, concentrated collection of stars situated approximately 33,600 light-years away in the constellation of Pegasus. First discovered by the Italian astronomer Giovanni Domenico Maraldi in 1746, M15 has been a fascinating point of study for astronomers for centuries.

Unpacking the Density of M15

The M15 Globular Cluster is exceptionally dense, a feature which sets it apart from most other globular clusters. Its core underwent a contraction known as “core collapse”, resulting in one of the starriest skies in the cosmos.

The Intriguing Neutron Stars

Adding to its appeal, the M15 Globular Cluster is home to more than 100 variable stars, pulsars that include a rare type of neutron star, and a planetary nebula - all of which add to its unique charm and significance.

M15’s Extraordinary Blue Straggler Stars

In the outer regions of M15, we find a significant collection of blue stragglers - stars that appear younger than they are and shine with an azure hue. Unraveling the secrets of these stars could potentially shift our understanding of stellar evolution.

M15’s Central Black Hole Mystery

One of the most perplexing mysteries surrounding M15 is the suspected presence of an intermediate-mass black hole at its heart. As of now, this remains a topic of ongoing debate and research among stellar physicists, adding another layer of allure to the M15 Globular Cluster.

Grab every opportunity to look up at the night sky. You could be observing a celestial marvel like the M15 Globular Cluster and be connected to the mysteries it holds.
