Deep space objects in late constellations

The late constellation contains 8 messier objects and a large number of galaxies and globular clusters. The northern part of the Virgo cluster is also located in this constellation, which also contains few open clusters and diffuse nebulae. the virgo cluster of galaxies

The northern part of the Virgo galaxy cluster is located in the embryo, also known as the embryo-Virgo galaxy cluster, 60 million light years away from the earth.

M 100(NGC 432 1): A spiral galaxy facing the earth, with an apparent magnitude of 9.37 and an observation diameter of 7 minutes, is the largest galaxy in the Virgo cluster. The distance is 4 1 100 million light years. Its line diameter exceeds 654.38+0.2 million light years, making it one of the largest spiral galaxies in the cluster. You can see a bright core, two spiral arms and other fine structures in the photo.

M85(NGC 4382): Lenticular galaxy, with an apparent magnitude of 9.22, is the brightest one in the cluster. The distance is 4 1 10,000 light years, and the line diameter is10.3 million light years.

M98(NGC 4 192): An elongated spiral galaxy with a bright but small core and large spiral arms. Apparent magnitude 10. 13, distance of 36 million light years, line diameter120,000 light years.

M99(NGC 4254): Located about 1.5 in the southeast of M98, the great circle spiral galaxy facing the earth has a small and bright core.

M88(NGC 450 1): A spiral galaxy with multiple spiral arms and a side view of about 30. Apparent magnitude 9.25, line diameter 1 1 billion light years, distance 4 1 billion light years.

M9 1(NGC 4548): A spiral galaxy with an apparent magnitude of 10.8 and a distance of 37 million light years.

Backward galaxy cluster

Located in the northern part of the Virgo galaxy cluster, it is 300-400 million light years away from the earth. It contains 1000 large galaxies, and the number of small galaxies can be as high as 30,000. 1957, a survey of the sky conducted by American astronomer Fritz Zwicky discovered 2995 1 galaxy, and their apparent magnitude was higher than 19.0.

Because this cluster is far away, the magnitude of the brightest galaxies NGC 4889 and NGC 4874 is only 13. Most galaxies can only be observed with large telescopes. NGC 4889 is a huge ellipsoid galaxy located in the center of Ursa Major.

Other galaxies

M64(NGC 4826) looks oval, and is also called "black-eyed galaxy" or "black-eyed nebula" because there is an obviously dim dust belt passing through the bright core. The apparent magnitude is 9.36, and the line diameter is 654.38+0.6 million light years, which is second only to M77 in messier objects and 24 million light years away from the Earth. Recent studies have found that the rotation direction of interstellar dust outside the galaxy is opposite to that inside, which may be because it collided with a nearby subsidiary galaxy 65.438 billion years ago.

NGC 4565 is located about 3' southeast of the late γ constellation. It is a spiral galaxy with a length of 16 minutes, also known as the "needle galaxy", and it is the largest galaxy facing the earth. The apparent magnitude is 9.56, and the distance is 20 million light years. M53(NGC 5024), a globular cluster discovered by Bode in 1775, was independently discovered by Charles Messier in 1777. With binoculars, you can see the apparent magnitude of 7.7. It is 65,000 light years away from the Earth, and its brightness is equivalent to 200,000 suns.

Another globular cluster NGC 5053, which is away from M53 cluster 1, was discovered by John Herschel in 1784. The apparent magnitude is 9.9, with relative dispersion and low nuclear density.

NGC 4 147, a darker globular cluster (apparent magnitude 10.2), is also much smaller. PG 1247+26 is the brightest quasar in this constellation. The later W constellation was originally thought to be a variable star, but later it was found to belong to Scorpio BL celestial body. Usually the apparent magnitude is 16.5m, but sometimes it can reach 12.
