#messiermarathon — Public Fediverse posts

Want to try to do a #messierMarathon in 2024 (weather permitting). I was surprised as to how many objects on the list I haven’t seen despite being a deep sky observer for decades.

To close out Hubble's 2023 #MessierMarathon, here's a new image of M19!

M19 is a star cluster with a slightly elongated shape. It's relatively close to the heart of our Milky Way, so the gravity from the galactic center could be stretching it: https://go.nasa.gov/40mqDld

Just in time for the 2023 #MessierMarathon, Hubble has a new view of M80 to share.

M80 is one of the densest globular clusters in the Milky Way. It's about 28,000 light-years away from Earth and contains hundreds of thousands of stars: https://go.nasa.gov/3JNPpp1

Hubble has imaged most of the objects in the Messier catalog, which includes fascinating astronomical targets that can be observed from the northern hemisphere.

You can even try to find them all for a #MessierMarathon in March's ideal viewing conditions!

The Crab Nebula is also classified as “Messier 1” – the first object in the Messier catalog, a list of cosmic objects compiled by astronomer Charles Messier.

In fact, some astronomers will even attempt a #MessierMarathon: a challenge to find all the catalog’s objects in a night!

M81 Bode's Galaxy

Messier 81 (also known as NGC 3031 or Bode's Galaxy) is a grand design spiral galaxy about 12 million light-years away in the constellation Ursa Major.

M1 Crab Nebula

M1 Crab Nebula is a supernova remnant and pulsar wind nebula. It is located in the northern constellation Taurus, the Bull. The Crab Nebula has an apparent magnitude of 8.4 and lies at a distance of 6,500 light years from Earth. It is the result of a supernova explosion, SN 1054, that was observed by Chinese astronomers in 1054 AD.

M42 Great Nebula in Orion

Messier 42 (M42), the famous Orion Nebula, is an emission-reflection nebula located in the constellation Orion, the Hunter. With an apparent magnitude of 4.0, the Orion Nebula is one of the brightest nebulae in the sky and is visible to the naked eye. It lies at a distance of 1,344 light years from Earth and is the nearest stellar nursery to Earth.

M92

Magnitude 6.4 globular cluster located 26,700 light-years away in the constellation Hercules. M92 is approaching us at 112 km/sec and was a "Polarissima Borealis", or "North Cluster", about 12,000 years ago (10,000 BC), and it will again in about 14,000 years (16,000 AD).

M13

Located 25,000 light-years from Earth, M13 is by far the most famous sight in this part of the sky. It competes with M5 as the brightest globular cluster north of the celestial equator. The cluster contains some 500,000 stars with an age of 13 billion years, not much younger than the universe itself.

M15

Magnitude 6.2 globular cluster located 35,700 light-years away in the constellation Pegasus. At an estimated 12.5±1.3 billion years old, it is one of the oldest known globular clusters. Its core has undergone a contraction known as "core collapse" and it has a central density cusp with an enormous number of stars surrounding what may be a central black hole.

M32

Magnitude 8.08 dwarf galaxy located 2.65 million light-years away in the constellation Andromeda. It is a satellite galaxy of M31 (Andromeda Galaxy) and was discovered by Guillaume Le Gentil in 1749.

M31 Andromeda Galaxy

Magnitude 3.44 barred spiral galaxy located 2.5 million light-years away in the constellation Andromeda. It is the nearest large galaxy to our own and is approaching the Milky Way at about 110 km per second (68 miles per second). The two galaxies are expected to collide in 4-5 billion years.

M7 Ptolemy’s Cluster

Magnitude 3.3 open cluster located 980 light-years away in the constellation Scorpius. It was first recorded by the 2nd-century Greek-Roman astronomer Ptolemy, who described it as a nebula in 130 AD.
