On Earth, they record hundreds of strange explosions similar to those discovered in the depths of the universe

Bright flashes of light burn for a few milliseconds before disappearing without a trace.
An international team of scientists has discovered more than 500 mysterious fast radio bursts (FRBs) coming from the depths of the universe, Communication This Wednesday the Massachusetts Institute of Technology in the United States.
FRBs are Strange flashes of light, which were recorded in the radio range of the electromagnetic spectrum and glowed for a few milliseconds before disappear without a trace. These explosions were detected in different and distant parts of the universe, as well as in our galaxy. Its origins are unknown and its appearance is unpredictable.
Since the beginning Radio blast In 2007, only about 140 other such eruptions were seen. but with the help fixed wireless telescopelocated in the Canadian province of British Columbia 535 new FRBs During its first year of operation, between 2018 and 2019.
Importance of FRBs
Also, these downloads throw some Evidence about its properties. For example, they seem to fall into two categories: frequent bursts and non-recurring bursts. Eighteen frequently erupted FRBs have been identified, while the rest appear to be unique. Also, the repetition of flashes lasts a little longer and sounds More focused radio frequencies of individual bursts.
This leads scientists to assume that the two types of eruptions It arises from different mechanisms and astrophysical sources. These discoveries are expected to help not only understand where FRBs come from and their properties, but also to measure other important features of the universe such as mapping gas distribution all over the universe.
“With all of these sources, we can really start to build a picture What do FRBs look like? Taken together, what astrophysics might drive these events and how they might be used to study the universe “In the future,” said study co-author Caitlin Shen of the Massachusetts Institute of Technology.
