Messier 92 – the NGC 6341 Globular Cluster

Welcome back to Messier Monday! Today, we continue in our tribute to our dear friend, Tammy Plotner, by looking at the globular cluster known as Messier 92!

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 Messier 92, a globular cluster located in the northern constellation of Hercules. This cluster lies at a distance of 26,700 light-years from Earth and is also approaching our galaxy at a speed of about 112 km/s (403,200 km/h; 250,500 mph) – which means it will eventually merge with our own. With an average estimated age of 14.2 billion years (± 1.2 billion years), it is almost as old as the Universe itself!

Messier 90 – the NGC 4569 Spiral Galaxy

Welcome back to Messier Monday! Today, we continue in our tribute to our dear friend, Tammy Plotner, by looking at the approaching spiral galaxy known as Messier 90!

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 intermediate spiral galaxy known as Messier 90, which is located about 60 million light-years away in the constellation Virgo – making it part of the Virgo Cluster. Unlike most galaxies in the local group, Messier 90 is one of the few that have been found to be slowly moving closer the Milky Way (the others being the Andromeda and the Triangulum galaxy).

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 spiral galaxy known as Messier 88 (New General Catalog designation 4501), a spiral galaxy located between 50 and 60 million light-years away in the constellation Coma Berenices. M88 was one of the first celestial objects to be recognized as a spiral galaxy and is one of the brighter galaxies of its kind in the Virgo Cluster.

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.

Messier 82 – the Cigar Galaxy

Welcome back to Messier Monday! Today, we continue in our tribute to our dear friend, Tammy Plotner, by looking at the Cigar Galaxy – also known as Messier 82!

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 starbust galaxy known as Messier 82, which is also called the “Cigar Galaxy” because of its distinctive shape. Located about 12 million light-years away in the constellation Ursa Major, this galaxy’s starburst action is thought to have been triggered by interactions with the neighboring galaxy M81 (aka. Bode’s Galaxy).
