In the latest development, the Hubble telescope has now started a new mission to study about six large galaxy clusters which will be helping in throwing some light on about the earliest galaxies which are evolved in the universe. This learning about the formation as well as the evolution of the galaxies in this universe which is said to be crucial for the understanding of the cosmos.
It has been seen that this telescope has already detected some of the distant galaxies, but their number are small as they make it very hard for astronomers to determine what they represent in this universe. As per the initial observations which are from the Beyond Ultra-deep Frontier Fields and Legacy Observations (BUFFALO) survey, it shows that the galaxy cluster Abell 370, as well as a host of magnified and gravitationally lensed galaxies, are present around it. There are massive galaxy clusters which are similar to A370 that can help the astronomers to find some more distant objects.
Abell 370 is said to be located at about 4 billion light-years from Earth which is then situated in the constellation Cetus or the Sea Monster. To explore the six Frontier Field galaxy clusters, there are 101 Hubble orbits which are corresponding to about 160 hours of some precious time, as said by the NASA.
It has been said that this BUFFALO survey will be taking advantage of other space telescopes which have already observed this region which are around the clusters. They include the search for the first galaxies. The immense masses of galaxy clusters will help them to act as cosmic magnifying glasses.
This kind of cluster mass will help in bending as well as magnifying the light from the more distant objects which are behind it. They have uncovered objects which are otherwise get too faint for even Hubble’s sensitive vision. This cosmological trick is known as strong gravitational lensing which is Hubble that is to explore some of the earliest as well as most distant galaxies in this universe.
It has been seen that there is most of the stunning demonstration of about gravitational lensing which can be seen in the recent image which is beamed back to the space telescope. This was nicknamed the Dragon as this feature is made up of a multitude of duplicated images due to the spiral galaxy which lies beyond the cluster.
