Messier 89 – the NGC 4552 Spiral Galaxy

Welcome back to Messier Monday! Today, we continue in our tribute to our dear friend, Tammy Plotner, by looking at the spiral galaxy known as Messier 89!

During the 18th century, famed French astronomer Charles Messier noticed the presence of several “nebulous objects”  while surveying the night sky. Originally mistaking these objects for comets, he began to catalog them so that others would not make the same mistake. Today, the resulting list (known as the Messier Catalog) includes over 100 objects and is one of the most influential catalogs of Deep Space Objects.

One of these objects is the elliptical galaxy known as Messier 89, which is located about 50 million light years from Earth in the constellation Virgo. This makes it part of the Virgo Cluster, a collection of 2,000 galaxies that lie in the direction of the Virgo and Coma Berenices constellations. This galaxy is not as bright as some other members, which makes it somewhat difficult to spot in small telescopes.

Messier 87 – the Virgo A Supergiant Galaxy

Welcome back to Messier Monday! Today, we continue in our tribute to our dear friend, Tammy Plotner, by looking at the supergiant elliptical galaxy known as Messier 87 (aka. Virgo A)!

During the 18th century, famed French astronomer Charles Messier noticed the presence of several “nebulous objects”  while surveying the night sky. Originally mistaking these objects for comets, he began to catalog them so that others would not make the same mistake. Today, the resulting list (known as the Messier Catalog) includes over 100 objects and is one of the most influential catalogs of Deep Space Objects.

One of these objects is the supergiant galaxy Messier 87, also known as the Virgo A (or the Smoking Gun) galaxies. Located at a distance of about 53.5 million light years from Earth, this galaxy is home to several trillion stars, 15,000 globular clusters, and a supermassive black hole. It is one of the brightest galaxies in the northern part of the Virgo Cluster, second only to Messier 49, and the dominant member of that group.

Messier 84 – the NGC Elliptical Galaxy

Welcome back to Messier Monday! Today, we continue in our tribute to our dear friend, Tammy Plotner, by looking at the elliptical (lenticular) galaxy known as Messier 84!

During the 18th century, famed French astronomer Charles Messier noticed the presence of several “nebulous objects”  while surveying the night sky. Originally mistaking these objects for comets, he began to catalog them so that others would not make the same mistake. Today, the resulting list (known as the Messier Catalog) includes over 100 objects and is one of the most influential catalogs of Deep Space Objects.

One of these objects is known as Messier 84, an elliptical (or lenticular) galaxy located about 54.9 million light years from Earth. This galaxy is situated in the inner core of the heavily populated Virgo Cluster and has two jets of matter shooting out of its center. It also has a rapidly rotating disk of gas and stars that are indicative of a supermassive black hole of 1.5 billion Solar masses at its center.

Messier 83 – the Southern Pinwheel Galaxy

Welcome back to Messier Monday! Today, we continue in our tribute to our dear friend, Tammy Plotner, by looking at the Southern Pinwheel Galaxy – also known as Messier 83!

During the 18th century, famed French astronomer Charles Messier noticed the presence of several “nebulous objects”  while surveying the night sky. Originally mistaking these objects for comets, he began to catalog them so that others would not make the same mistake. Today, the resulting list (known as the Messier Catalog) includes over 100 objects and is one of the most influential catalogs of Deep Space Objects.

One of these objects is the Southern Pinwheel Galaxy (aka. Messier 83), a barred spiral galaxy located 15.21 million light years from Earth in the southern constellation Hydra. With a spatial diameter of about 55,000 light years, or roughly half the size of the Milky Way, M83 is one of the nearest and brightest barred spirals in the sky.
