In an area of space, millions of light-years away from the Milky Way, astronomers have glimpsed for years a bright spot without knowing what it was hiding. An enigma recently deciphered by a team of scientists, discovering that behind this element is a group of galaxies.
The universe is expanding, and has a very special structure in which stars like the Sun, of which there are billions, are organized into groups called galaxies. But these in turn form other groups, called groups of galaxies.
The closest group of galaxies to the Milky Way is the Virgo, which comprises about 2,000 galaxies 60 million light-years away from Earth. The new group of galaxies is located 2,400 million light-years away
The Argentine astrophysicist, Mario Díaz, director of the Gravitational Wave Astronomy Center at the University of Texas of the Rio Grande Valley, explained to Sputnik
"They found a cluster of galaxies that they thought were a point, but it was actually billions of galaxies that were there, and that were supermbadive holes in the center of the galaxies. "
The discovery was the result of the work of a team of scientists who were looking for possible groups of galaxies, from singular points captured by the CHIPS survey (Clusters Hiding in Plain Sight), in Spanish. , "Cúmulos ocultos a la vista".
For this survey, researchers used data obtained from a wide range of studies from X-ray missions, including NASA's ROSAT satellite and Chandra
]. which is done in X-rays, and in electromagnetic field regimes, it is much more telling, than if we look at it, either in the optical regime, in what our eyes see, radio, or some other type of electromagnetic spectrum it does not have the energy that X-rays have, "said Diaz
