Australian telescope detects more mysterious radio signals

A newly discovered radio burst 6 billion light years away has further puzzled astronomers about the source of the signal.

Just four days after starting the study, the Australian Square Kilometre Array Pathfinder (ASKAP) telescope located near Murchison, Western Australia, detected a rare burst of radio waves, also known as a radio burst, coming from the constellation Leo, Longroom reported yesterday.

These unique signals, lasting only a few milliseconds, are thought to originate billions of light years away. However, scientists still don't know exactly what causes them.

A team from the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Curtin University and the International Centre for Radio Astronomy Research (ICRAR) discovered the new burst using just eight telescope dishes.

The ASKAP telescope is equipped with a total of 36 dishes, which can observe a single location in the sky or point in different directions. When using 8 dishes, the device can simultaneously monitor a 240-degree coverage.

The new burst, FRB170107, is extremely bright and therefore easy to spot. By using more dishes, the team may be able to detect more bursts. The latest burst comes from the edge of the constellation Leo.

FRB170107 likely traveled through the universe for 6 billion years at the speed of light before being detected by telescopes. Its brightness and distance suggest that the burst was associated with a huge energy source.

But the new findings make it even harder to pinpoint the source of the signal. "We're making a difficult problem even harder," said Dr. Ryan Shannon, who analyzed the strength and location of the bursts.
