Astronomers have conducted a detailed study of a cluster of galaxies very young and very massive, IDCS 1426 using three observatories NASA in visible light with Telescope orbital Hubble, infrared Spitzer Space Telescope, respectively in X-rays by Chandra x-ray Observatory. The result is this picture of the three observations made up of pictures taken from three observatories.

This rare galactic cluster, located about 10 billion light years from Earth, has a mass equivalent to an estimated 500 trillion suns. The study of this cosmic object can provide important information about how such Megastructures formed and evolved during the heyday of the universe. This composite image of galaxy cluster IDCS 1426 dates when the universe was less than one third of its current age, or about 3.8 billion years and 1426 is the IDCS massive galactic cluster or clusters detected during this period of youth Universe.

Discovered by the Spitzer Space Telescope in 2012, 1426 IDCS was then observed through the lens telescopes Hubble and Keck Observatory in order to determine the distance at which it is located. The first observations carried out indicated that it is an extraordinarily massive galactic cluster. New data obtained by Chandra X-ray Observatory have confirmed the mass of this cluster galactic and led to the conclusion that about 90% of this mass is the fact dark matter - the mysterious substance that has not yet been detected directly, but only based on the gravitational influence it exerts on ordinary matter, made of atoms.

Near the center of the cluster is a region in which X-rays are emitted very bright (in blue and white), but not in the center of the swarm. The location of this core cluster suggests that cosmic gas would have collided with another massive system of galaxies relatively recently, probably when the age of the universe was only 3.3 billion years. This core of gas, although in turn extremely hot, it contains gas cooler than the surrounding areas. Observing a core of gas so "cold" in a galactic cluster so far, is again a first.

Astronomers believe that the study of such core "cold" is important to understand how quickly they lose heat from hot gases such swarms, a phenomenon that affects the rate of fire of new stars. This cooling rate can be slowed and action supermassive black hole in the center of the swarm.

I started my career as an intern at NASA. I've worked at several companies in Silicon Valley. In fact, I gave in 1986, an interview with Pixar, but I went to them. I accepted another offer. After a few years, I thought things were not what I wanted them, so I came back. I kept in touch with them. Initially, I was hired to work with their software. RenderMan take care of a plug-in compatible with major 3D animation software platforms, McCoy told AFP, adding that he began to develop his artistic skills when he had to work with photos.

I joined the team early enough to travel to Paris "joked McCoy. The food is difficult because people are so constructed that detects whether or not the food looks delicious. We did eat in our films. For example, in The Incredibles "family dinner. If you look closely, that food is not that great, but it was subject. But the people watching Ratatouille food and delicious dish should look. I said, 'Wow, I've never done anything like this before. We had practically to make food look alive. Most times, you are told to do something look nice, but sometimes you are asked to do something you look more delicious.
