Oftentimes astronomers focus on distant galaxies in an effort to better understand the layout of the universe, and perhaps even tell us something about how our own galaxy has evolved over time. A large galaxy lurking far in the cosmos recently caught the eye of scientists for a completely different reason: It sent a signal that we were able to detect here on Earth
The galaxy, carrying the complex scientific label DES J214425. 25-405400.81, is a whopping 4 billion light-years away, but it has been pegged as the source of a single, non-repeating fast radio burst (FRB) that was heard loud and clear by an array of radar dishes in Australia. 19659003] Upon its detection, researchers began investigating the possible source of the FRB, managing to find the galaxy that was beamed from, but narrowing the source to a rather specific spot within the galaxy itself. research paper, scientists who hunted down the source of the radio signal revealed that the signal originated some 1
Hearing that we have detected that an intergalactic radio signal might make your mind wander a bit, but before you go to dream of aliens trying to hail other civilizations, you should know that scientists are taking a much more measured approach to things
It's likely, researchers say, that the signals are produced by one of several possible stellar phenomena. The collapse of stars or even black holes of tearing stars apart could possibly explain these radio blasts, but right now there is no definitive answer.
