Researchers have managed to find that mysterious radio pulses may exist for a much shorter period of time than expected.
According to a study published in the journal Nature Astronomy, astronomers have discovered a new type of mysterious cosmic phenomenon called fast radio bursts. These are ultra-fast ballistic missiles that last only one ten-millionth of a second. Previously, scientists had only found longer-lasting bursts of energy from deep space, ScienceAlert writes.

Fast radio bursts (FRBs) are bright and extremely short-lived bursts of radio emissions that release in a fraction of a second the same amount of energy that the Sun produces in several days. Most BRVs appear only once, but there are some that occur repeatedly. They were first discovered just 16 years ago.
These are some of the most mysterious radio signals in the Universe, coming to us mostly from outside our galaxy. Scientists don’t know exactly what triggers these high-energy events, which last for a fraction of a second, but some theories suggest they may be related to magnetars, which are neutron stars with the strongest magnetic fields in the Universe. To date, scientists have been able to detect the appearance of more than a thousand FRBs, and only 25 of them are repeating fast radio bursts.
Scientists thought FRBs could exist in a thousandth of a second, but a new study has shown that they can actually only exist in a millionth of a second. The discovery was made as part of a study of five hours of observational data from a known FRB, called FRB 20121102A, discovered in 2012. Just last year, astronomers discovered that this FRB was the first known repeating fast radio burst. The source of this radio emission is 3 billion light years away.
The study authors used the first 30 minutes of data and divided each second into 500 thousand separate images. They then used artificial intelligence to process the results. As a result, 8 ultrafast radio bursts were discovered simultaneously, existing for only one ten-millionth of a second, that is, 0.0000001 seconds.
Thus, scientists concluded that a new type of FRB exists and that they occur much more frequently and with greater diversity than previously thought. This affects the understanding of the nature of these mysterious events.
But the question of how such ultrafast radio bursts arise still remains unanswered, but according to scientists, further observations may clarify the situation. However, there is little FRB observation data that can be split into hundreds of thousands of images per second.
In more detail about what FRBs are according to modern research, Focus already wrote.
Moreover Focus wrote about the results of a recent study in which scientists searched for the source of the origin of BRV.
