Radio emissions from deep in space have scientists baffled. What could this mean for us all in the future?
These unidentified radio emissions were recorded in July by a new radio telescope in British Columbia. While it is just a mere 20 seconds, it is still quite a mystery to us all. These emissions are known as fast radio bursts and they are the first ever that the Canadian Hydrogen Intensity Mapping Experiment (CHIME) has detected thus far.
For those who might not be aware, FRBs are milliseconds-long bursts of radio emissions that come from sources we are unable to identify across the Universe. CHIME has been present for less than a year and was designed to gather data on these kinds of FRBs. The FRBs detected, in this case, are referred to as FRB 180725A and is quite unique because of the low frequency it comes with. It had a frequency as low as 58p Mhz. You see, no FRB has ever been detected below a frequency of 700 Mhz until now.
While these kinds of signals are not necessarily rare, we haven’t known about them for long. They have only been recorded in the past decade or so and that means we have really been missing out. There is a lot of mystery surrounding them.
These kinds of things come from far beyond our home galaxy and can hold a lot of interesting things for us if we can figure out how to uncover their secrets. While there could be several possible explanations for these kinds of signals, nothing has been set in stone just yet. Perhaps they come from exploding black holes or even have something to do with aliens trying to make contact? We can only hope to figure things out in the future.
This most recent discovery was reported in an online ‘Astronomer’s Telegram’ post, one in which other astronomers were told to begin searching for repeated bursts and wavelengths. What do you think this could mean?
