Abell 1835 is a galaxy cluster in the Abell catalogue. It is a cluster that also gravitational lenses more-distant background galaxies to make them visible to astronomers. The cluster has a red shift of around 75,900 km/s and spans 12′.
Microraptor is a genus of small, four-winged dromaeosaurid dinosaurs. Numerous well-preserved fossil specimens have been recovered from Liaoning, China. They date from the early Cretaceous Jiufotang Formation, 125 to 120 million years ago. Three species have been named, though further study has suggested that all of them represent variation in a single species, which is properly called M. zhaoianus. Cryptovolans, initially described as another four-winged dinosaur, is usually considered to be a synonym of Microraptor.
Abell 2029 or A2029 is a large cluster of galaxies 315 megaparsecs away in the constellation Virgo. A2029 is a Bautz–Morgan classification type I cluster due to its large central galaxy, IC 1101. Abell 2029 has a diameter of 5.8–8 million light-years. This type of galaxy is called a cD-type brightest cluster galaxy and may have grown to its large size by accreting nearby galaxies. Despite its relaxed state, it is the central member of a large supercluster which shows clear signs of interaction.
52P/Harrington–Abell is a periodic comet in the Solar System.
Abell 400 is a galaxy cluster which contains the galaxy NGC 1128 with two supermassive black holes spiraling towards merger.
Abell 1689 is a galaxy cluster in the constellation Virgo over 2.3 billion light-years away.
Earl C. "Tuffy" Abell was an American football player and coach. He played college football as a tackle at Colgate University. He later returned to Colgate as an assistant coach in 1925, and took over the head coaching job in 1928. He spent the 1929 and 1930 football seasons as head football coach at the University of Virginia. Abell was inducted into the College Football Hall of Fame as player in 1973.
The Abell S740 is a cluster of galaxies identified in the Abell catalogue of southern rich clusters of galaxies. It is over 450 Mly away in the constellation Centaurus. It has a redshift of 10,073 km/s.
Abell 370 is a galaxy cluster located nearly 5 billion light-years away from the Earth, in the constellation Cetus. Its core is made up of several hundred galaxies. It was catalogued by George Abell, and is the most distant of the clusters he catalogued.
Abell 383 is a galaxy cluster in the Abell catalogue.
Abell 2147 is a galaxy cluster in the Abell catalogue. It is located within the core of the Hercules Superclusters, within Serpens Caput, near the cluster Abell 2152, approximately two degrees south southwest of the Hercules Cluster. It is possible that Abell 2147 is actually part of the Hercules Cluster considering that it shares the same redshift of 550 million light years.
Abell 133 is a galaxy cluster in the Abell catalogue.
Abell 262 is a galaxy cluster in the Abell catalogue. It is part of the Perseus-Pisces Supercluster, one of the largest known structures in the universe. Although its central galaxy, NGC 708, is a giant cD galaxy, most of its bright galaxies are spirals, which is unusual for a galaxy cluster. With approximately 200 members it is a comparatively small cluster.
Abell 1413 is a galaxy cluster in the Abell catalogue. The Abell catalogue was published by George O. Abell in 1958 while working on his PhD at California Institute of Technology. The catalogue has two different surveys. The Northern survey was done first by Abell in 1958 with the help of A.G. Wilson. The Northern Survey has 2,712 clusters, and in order for a cluster to be put into the catalogue it must pass four criteria. The first criterion is richness, and Abell divided the clusters into 6 different richness groups. Group 0 was 30-49 galaxies, Group 1 was 50-79 galaxies, Group 2 was 80-129 galaxies, Group 3 was 130 to 199 galaxies, Group 4 was 200-299 galaxies, and Group 5 was more than 299 galaxies. The second criterion was compactness. To meet this requirement a cluster must have 50 or more members in one counting radius of the cluster's center. The third criterion is distance. A cluster must have a nominal redshift between .02 and .2, which means a recessional velocity is between 6,000 and 60,000 km/s. The fourth and final criterion was galactic latitude. Areas around the milky way were excluded because it was difficult to identify galaxy clusters. The Southern survey was done in 1989 and added 1,361 clusters using the same criteria as the Northern Survey.
Abell 1795 is a galaxy cluster in the Abell catalogue.
Abell 222 is a galaxy cluster in the constellation of Cetus. It holds thousands of galaxies together. It is located at a distance of 2.4 billion light-years from Earth.
Abell 223 is a galaxy cluster. It is located at a distance of 2.4 billion light-years from Earth. The cluster is connected to nearby cluster Abell 222 by a filament of matter. Research has shown that only 20% of that matter is normal. The rest is thought to be dark matter. This means that this would form the Abell 222/ Abell 223 Supercluster as we understand them.
Abell 70 is a planetary nebula located 13,500-17,500 light years away in the constellation of Aquila. It is approaching the earth at 79 kilometers per second and expanding 38 kilometers per second. There is a galaxy named PMN J2033-0656 behind Abell 70, giving it a diamond ring effect.
Abell 36 is a planetary nebula located 780 light years away in the constellation of Virgo.
Thomas Benjamin Abell is an English first-class cricketer who plays for Somerset County Cricket Club.
