Often, astronomers focus on distant galaxies to better understand the structure of the universe, and may even tell us something about how our own galaxy has evolved over time. A large galaxy lurking far in the cosmos has recently caught the attention of scientists for a very different reason: it sent a signal that we could detect here on Earth.
The galaxy bearing the complex scientific label DES J214425. 25-405400.81, is a whopping 4 billion light-years away, but was considered to be the source of a single, non-repeating, rapid radio burst (FRB) that was heard loud and clear by a number of radar courts in Australia.  After their discovery, the researchers began to investigate the possible source of the FRB. In addition to finding the galaxy from which it was broadcast, they narrowed the source to a specific point within the galaxy itself.
In a recent research, scientists who tracked down the source of the radio signal found that the signal was about 1
We've found that an intergalactic radio signal makes your thoughts a little confused, but before you dream of aliens trying to hail other civilizations, you should know that scientists are taking a much more measured approach.
It is likely that researchers say that the signals are generated by one of several possible stellar phenomena. The collapse of stars or even the breaking of stars through black holes could possibly explain these radio beams, but at present there is no definitive answer. Whatever it is, they are probably not aliens.
