Galaxy Cluster SDSS J1226+2152: its immense mass distorts and magnifies the light from more distant galaxies behind it - a spectacular example of gravitational lensing

The Hydra Cluster of Galaxies - August 1st, 1996.

"You are flying through space and come to...the Hydra Cluster of galaxies. Listed as Abell 1060, the Hydra Cluster contains well over 100 bright galaxies. Clusters of galaxies are the largest gravitationally-bound objects in the Universe. All of the bright extended images in the above picture are galaxies in the Hydra Cluster, with the exception of unrelated diffraction crosses centered on bright stars. Several proximate clusters and galaxy groups might together create an even larger entity - a supercluster - but these clumps of matter are not falling toward each other. In fact, the Hydra Cluster is thought to be part of the Hydra-Centaurus Supercluster of galaxies. Similarly, our own Milky Way galaxy is part of the Local Group of galaxies, which is part of the Virgo Supercluster of galaxies."

The celestial object of the day is El Gordo!

This galaxy cluster is located 7 billion light-years away from Earth, and it formed when the universe was only half the age it is currently. Its ginormous mass (2.1 quadrillion solar masses) helps scientists see galaxies that are very far away thanks to gravitational lensing

SPACEMAS DAY 2 ✨🪐🌎☄️☀️🌕

There's a new space telescope in the sky: Euclid. Equipped with two large panoramic cameras, Euclid captures light from the visible all the way to the near-infrared. It took five hours of observing for Euclid's 1.2-meter diameter primary mirror to capture, the 1000+ galaxies in the Perseus cluster which lies 250 million light years away. More than 100,000 galaxies are visible in the background, some as far away as 10 billion light years. Euclid's initial surveys, covering a third of the sky and recording over 2 billion galaxies, will enable a study of how dark matter and dark energy have shaped our universe.

The first images from the ESA Euclid Telescope are here. It's impossible not to be fascinated about the universe.

The Coma Cluster of Galaxies - November 5th, 1996.

"Almost every object in the above photograph is a galaxy. The Coma Cluster of galaxies pictured is one of the densest clusters known - it contains thousands of galaxies. Each of these galaxies house billions of stars - just like our own Milky Way galaxy. Although nearby when compared to most other clusters, light from the Coma Cluster still takes hundreds of millions of years to reach us. In fact, the Coma Cluster is so big it takes light millions of years just to go from one side to the other! Most galaxies in Coma and other clusters are ellipticals, while most galaxies outside of clusters are spirals."

Stephan's Quintet

This galaxy cluster, appearing between 41 and 340 million light years away from us, was first discovered by the French astronomer E. M. Stephan in 1877. The galaxies are a mixture of spirals, barred spirals, and ellipticals. Some scientists think that the largest galaxy in this cluster, NGC 7320, is probably in front of what is really a quartet of interacting galaxies, and since then there have been many discussions between scientists with different theories on what this actually means.
