What keeps galactic clusters together?

Specialised connective tissue in our body holds the organs in our body in place$rarr$ Mesentry Our body organs are attatched to the body wall with the help of mesentry. It...

Clusters are a mas connection of many galaxies. And super clusters are a large group of many clusters or galaxy groups.

The Hubble constant describes the . The Hubble Constant was revealed when Edwin hubble found a correlation between the distance of a galaxy and its velocity. He found a correlation...

So such stars can be used as standard candles to calculate distance to globular clusters.

The address of : Cluster - Laniakea Supercluster Galaxy - Milky Way Arm - Spiral Arm (Orion Arm) Solar System - that of our Sun

Harlow Shapley analysed the locations of globular clusters, finding them to be centred around a point somewhere in Sagittarius. He deduced that this was probably the location of the centre...

These winds have often been observed in galaxies, and can travel at speeds between 300 and 3,000 km/s. The winds can either blow the material into the halo of the...

The Andromeda galaxy is over 2.5 million light years away. For galactic cannibalism to occur, the galaxies have to be much much closer, so that their gravities can impact one...

It is thought that most large galaxies have a supermassive black hole at their centre. Regular galaxies have relatively little material in the vicinity of the black hole and hence...

Seyfert galaxies and quasars are galaxies with an active galactic nucleus. Most large galaxies have a supermassive black hole at their centres. If their is material falling into the black...
