LIFE IN SPACE?: Unknown radio signals from distant galaxy found

One of the newly detected bursts is a rare "repeater" - researchers saw six flashes coming from the same spot in the sky, which they hope will make it easier to pin down the source of the signal.

A telescope in Canada picked up mysterious signals emanating from a distant galaxy.

The findings were announced by Deborah Good, an astronomer at the University of British Columbia in Vancouver, at a meeting of the American Astronomical Society in Washington on Wednesday.

Of the FRBs observed to date, repeating bursts from a single source had been found only once before - a discovery made by the Arecibo radio telescope in Puerto Rico in 2015. "And with more repeaters and more sources available for study, we may be able to understand these cosmic puzzles - where they're from and what causes them", astrophysicist Ingrid Stairs told the Independent. It was one of 13 new FRBs the team detected during three weeks in the summer of 2018. Scientists are still debating whether repeating FRBs come from the same source as the one-time flashes, or instead represent a distinct type of event. "We would like to know what kinds of objects these are and how they are related to other explosions and objects that we know of (gamma-ray bursts, supernovae, neutron stars etc)", Tendulkar said.

Shepard Smith conducted a rapid-fire rebuttal of some of the president's claims during his coverage on the Fox broadcast network. As of Tuesday morning, all the major cable and broadcast networks have confirmed that they will carry the Democratic speech.

One hypothesis is that powerful astrophysical phenomena are causing them.

Scientists have scores of theories about what might create such stupendous signals - spinning cores of collapsed stars, powerful magnetic fields around black holes, the fog of dust and gas from which new stars form.

The telescope only got up and running previous year, detecting 13 of the radio bursts nearly immediately, including the repeater.

The CHIME researchers are working with an array of antennas in central New Mexico to pin down the galaxy to which the second repeater belongs.

The team still believes Parsons will have value as an expiring contract, even if it takes into the offseason to make a deal. The 30-year-old Parsons signed with Memphis before the 2016-17 season on a four-year, $94 million contract.

While most FRBs have been spotted at wavelengths of a few centimetres, the latest FRBs were detected at wavelengths of almost a metre, which opens up new lines of inquiry, according to the CHIME team.

The CHIME team, which designed and built the telescope, includes 14 scientists from the University of B.C. alongside others from McGill University, the University of Toronto, the Perimeter Institute for Theoretical Physics and the National Research Council of Canada. "The closest analogs we have in our own galaxies (pulsars) are more than a trillion times fainter", Tendulkar said about the repeating FRB.

The FRBs show various temporal scattering behaviours, with the majority significantly scattered, and some apparently unscattered to within measurement uncertainty even at our lowest frequencies. The unexpectedly low 400 MHz frequency suggests FRBs might be detected at even lower frequencies, but another instrument would have to be used for that, as this is as low as CHIME can go.

"[We now know] the sources can produce low-frequency radio waves and those low-frequency waves can escape their environment, and are not too scattered to be detected by the time they reach the Earth", said Tom Landecker, a CHIME team member.

The Australian newspaper reported he left his hotel and "ran through the streets, bawling and hysterical". That moment sparked a late-career resurgence including back-to-back Australian Open titles.
