Astronomers have found a giant cluster of galaxies – called supercritical massive object (IPO) J1142 + 1527 – which sits in one of the the most remote corners of the universe.
According to the Jet Propulsion Laboratory, it looks like one of the biggest clusters ever found, and it sits so far, the picture above showcases cluster as it was about 8.5 billion years ago, long before the formation of the Earth. You can see the image in full here.
“Based on our understanding of how galaxies clusters grow from the very beginning of our universe, the cluster has to be one of the five most popular in existence at the time,” said Peter Eisenhardt JPL.
Clusters of galaxies are essentially groups of thousands of individual galaxies are pulled together by gravitational forces in the surrounding spaces.
Our own galaxy, the Milky Way, is part of a small group known as the Local Group. For size comparison, the newly discovered galaxy about a quadrillion times the size of our Sun
“But it was 8.5 billion years ago, and now the IPO one thousand one hundred forty-two + one thousand five hundred twenty-seven grow several times larger “Eisenhardt said TechRadar.
clusters in space
cluster was found with the help of NASA’s wide-field Infrared Survey Explorer (WISE) in a survey of the heavens in 2010-2011.
The astronomers then used NASA’s Spitzer Space Telescope to capture the cluster in more detail, while the data collected from the combined array for Research in Millimeter-wave Astronomy (CARMA) telescopes in northern California was used to estimate the size of the cluster.
JPL and NASA hope to learn more about the nature of dark energy in the universe by measuring the “history of the universe’s expansion and the growth of massive structures, the formation and evolution of quasars and galaxies, finding very distant examples from both the first billion years of the universe’s history, “Eisenhardt explained to TechRadar.
Dark energy is an unknown form of what is described as an energy that astrophysicists theorize penetrate the space between the galaxies, and may be the cause of expansion of the universe, and is the rate at which the expansion takes place.
They are also trying to open “if the general limits of the solar system habitable planets, finding more examples of the size of the planet Earth to Earth, the orbit around the Sun, the stars and study them in detail,” he said.
“Clusters of galaxies play an important role in the first two goals, in part because they can act as a gravitational magnifying glass for very distant galaxies.”
Unfortunately, Anthony Gonzalez of the University of Florida, lead author of a new study in the journal Astrophysical Journal Letters, explained to TechRadar, karma telescopes have recently been closed due to lack of funding.
“Thus, in the future we will have to rely on other means for measuring the mass of clusters, such as this one from our program,” said Gonzalez.
This cluster, however, is being observed in the framework of the Hubble Space Telescope, which is currently searching for distant supernovae in clusters of galaxies, to try to understand the nature of dark energy.
