Hubble eyes a powerful Galaxy with a Password Name

2XMM J143450.5+033843 lies nearly 400 million light-years away from Earth. It is a Seyfert galaxy that is dominated by something known as an Active Galactic Nucleus -- its core is thought to contain a supermassive black hole that is emitting huge amounts of radiation, pouring energetic X-rays out into the universe. The other fuzzy object in the frame was named in the same way -- it is a bright galaxy named 2XMM J143448.3+033749. Credit: ESA/Hubble & NASA

Not all galaxies have the luxury of possessing a simple moniker or quirky nickname. This impressive galaxy imaged by Hubble is one of the unlucky ones, and goes by a name that looks more like a password for a computer: 2XMM J143450.5+033843...

New image of Spectacular Concentration of Galaxies: Fornax Cluster

The Fornax Galaxy Cluster is one of the closest of such groupings beyond our Local Group of galaxies. This new VLT Survey Telescope image shows the central part of the cluster in great detail. At the lower-right is the elegant barred-spiral galaxy NGC 1365 and to the left the big elliptical NGC 1399. Credit: ESO. Acknowledgement: Aniello Grado and Luca Limatola

Clusters can contain anything between about 100 and 1000 galaxies and can be between about 5 and 30 million light-years across. Galaxy clusters do not come in neatly defined shapes so it is difficult to determine exactly where they begin and end. However, astronomers have estimated that the centre of the Fornax Cluster is in the region of 65 million light-years from Earth...
