More telescopes are being built across North America – which could help locate FRBs in the future, because they would be operating together, he added. ![]() What's everyone talking about?: Sign up for our trending newsletter to get the latest news of the day The team doesn't know which galaxy FRB 20191221A originates from, but they estimate that it's about 1 billion light-years away. Still, Michilli said, that's a "very rough estimate," and much remains unknown. Neutron stars are formed after giant stars die and the cores collapse.įRB 20191221A was first detected in December 2019 by a radio telescope called Canadian Hydrogen Intensity Mapping Experiment, or CHIME, at the Dominion Radio Astrophysical Observatory in British Columbia, Canada. Like other FRBs, the source of FRB 20191221A is a mystery – but the researchers noted that its emissions are similar to a radio pulsar or a magnetar, two types of neutron stars. In addition, the researchers found that the radio wave bursts repeated every 0.2 seconds, similar to the pattern of a "heartbeat." Typical FRBs "last about a millisecond, so much shorter than the blink of an eye," Michilli noted. FRB 20191221A has a duration of three seconds, about 1,000 times greater than the average. Repeating FRBs: Scientists detect an unexplainable radio signal from outer space that repeats every 16 daysīut the FRB detected in the new study, labeled FRB 20191221A, is particularly unique – for both how long the signal lasts and its pattern. And sometimes, some huge explosions happen that emit huge blasts of radio waves," Daniele Michilli, a postdoctoral scholar at MIT’s Kavli Institute for Astrophysics and Space Research and one of the study's authors, told USA TODAY. "We don't know what these explosions are, (but) they are so powerful that we can see them from across the universe."ĭeepest look into the cosmos: NASA releases 'sharpest' images of the universe from James Webb Space Telescope The exact origins of FRBs are unknown, but hundreds have been detected across the universe since the first FRB was discovered by scientists in 2007, according to a news release from the Massachusetts Institute of Technology. It also displays the clearest periodic pattern for an FRB found so far.įRBs are intense, very quick flashes of radio waves in space that are visible from billions of light-years away, the researchers note. In their findings, published in the peer-reviewed journal Nature on Wednesday, the researchers noted that the signal – classified as a fast radio burst, or FRB – is the longest-lasting of its kind ever detected. Policymakers are increasingly using satellite observations of methane emissions as curbing these releases - from fossil fuel production, agricultural activity and landfills - is one of the fastest and cheapest ways to reign in scorching temperatures within decades.Watch Video: A mysterious radio burst is sending signals to Earth every 16 daysĪstronomers have detected a mysterious radio burst, with a pattern similar to a beating heart, from a far-away galaxy. The initiative currently uses observations from satellite operators including Planet Labs PBC and Maxar Technologies Inc. to augment NASA’s own Earth observations.Īs the planet rapidly warms triggering extreme weather events from wildfires to heat waves, countries are getting more serious about tracking and halting avoidable leaks of methane, which has more than 80 times the warming power of carbon dioxide during its first 20 years in the atmosphere. Scientists at NASA’s Earth Science Division will evaluate the data under its commercial small satellite data acquisition program and assess if it can help achieve the agency’s wider goals, which include mapping the climate effects from human activity, according to a GHGSat statement Wednesday. in the latest sign governments are looking to curb leaks of the potent greenhouse gas.
