An international team of astronomers has identified fast radio bursts (FRBs) lasting only one millionth of a second, a fraction of the duration previously observed. The team's astonishing revelation may now shed new light on these enigmatic cosmic phenomena.
"By coincidence, I found out that there was a public dataset that we could use for this," stated lead author Mark Snelders, an astronomer at the University of Amsterdam.
The newly detected ultra-short bursts were traced back to the source FRB 20121102A, situated an astounding three billion-light years away from Earth. Previous observations had missed these microsecond pulses because data collection methods were not sensitive enough.
Officials have likened the discovery to searching for specific rocks in a pile of sand with a strainer, with the holes in the strainer being far too large to capture the sought-after objects.
The research team utilized data originally collected by the Green Bank Telescope, part of the Breakthrough Listen project, which initially aimed to search for radio signals from intelligent extraterrestrial life.
The unique characteristic can be leveraged to map out the otherwise difficult-to-observe regions between stars and galaxies, offering a more comprehensive understanding of how galaxies gather gas from the cosmos.

The discovery of these microsecond FRBs could potentially provide an even more precise tool for interstellar mapping, akin to upgrading one's prescription glasses for a clearer view of the universe.
With this groundbreaking finding, astronomers are eager to uncover more sources of the ultra-short bursts, which could further illuminate the cosmic mysteries that continue to captivate the scientific community.
The findings of the study were published in the journal Nature Astronomy.
