APOD: 2023 April 8 Б M100: A Grand Design Spiral Galaxy
8.04.2023

Majestic on a truly cosmic scale, M100 is appropriately known as a grand design spiral galaxy. It is a large galaxy of over 100 billion stars with well-defined spiral arms that is similar to our own Milky Way Galaxy.

Globular Cluster M2

Beneath the south pole of our Milky Way Galaxy lies a ball of over 100,000 stars. M2, the second object on Charles Messier's eighteenth century list of bright diffuse sky objects...

Starburst Cluster in NGC 3603
5.10.2007

A mere 20,000 light-years from the Sun lies NGC 3603, a resident of the nearby Carina spiral arm of our Milky Way Galaxy. NGC 3603 is well known to astronomers as one of the Milky Way's largest star-forming regions.

N81: Starbirth in the SMC
27.07.1998

A very young star cluster has been discovered in a neighboring galaxy. The stars found in this cluster, dubbed N81, are so young and massive that they furiously eject matter and light up the surrounding nebula. The ejected stellar winds combine and interact to sculpt beautiful and complex structures.

Star Cluster NGC 362 from Hubble
