Astronomy is one of the sciences that will never cease to surprise us, because in outer space there are an infinite number of things to discover, and one of them has just surprised a group of scientists.
It is nothing less than a giant galaxy, one hundred times more active than the Milky Way, and which researchers compare with the mythical snowman because of its dimensions.
In fact, according to current theories, there was no evidence that such galaxies existed, so they were perceived rather as a myth. However, the latest discovery turns myth into reality.RELATED
The finding, published in The Astrophysical Journal, was carried out by a team of astronomers from the United States and Australia, who determined that this monstrous galaxy is in the early Universe, at a great distance from Earth and is therefore situated , at a time close to the Big Bang.
Christina Williams, an astronomer at the University of Arizona and lead author of the work, explained that she noticed “a slight spot of light” while reviewing the images of the latest observations made with ALMA (Atacama Large Millimeter Array), a collection of 66 radio telescopes deployed in Chile.
According to the researcher, the glow seemed to be coming out “out of nowhere,” something like we saw a ghost in the midst of the deepest darkness.
The researchers estimate that the signal took 12.5 billion years to reach Earth, which gives us an idea of the Universe in its infancy. In addition, they believe that the observed radiation is caused by the warm glow of star-heated dust particles that form deep within a young galaxy.
"We discovered that, in reality, it is a monstrous galaxy, enormously massive, with as many stars as our Milky Way but full of activity, forming new stars at a rate 100 times higher than our own galaxy," said Williams.
