The latest observations from Insight-HXMT were published online in Nature Astronomy on Feb. 18. Insight-HXMT has discovered the very first X-ray burst associated with a fast radio burst (FRB) and has identified that it originated from soft-gamma repeater (SGR) J1935+2154, which is a magnetar in our Milky Way.

A brief history: What we know so far about fast radio bursts across the universe
Fast radio bursts are one of the great mysteries of the universe. Since their discovery, we have learned a great deal about these intense millisecond-duration pulses. Source: https://phys.org/news/2021-02-history-fast-radio-universe.html…
China’s huge FAST telescope to open to international observers
FAST’s 500-meter (1,640-foot) dish makes it the world’s largest single-dish radio observatory. It’s expected to open to international observers in 2021. Source: https://earthsky.org/space/worlds-largest-radio-telescope-china-fast…
Hubble sees the brightest kilonova yet
Observations by the Hubble Space Telescope reveal intense infrared radiation from an unusual kilonova probably created by the collision of neutron stars. Source: https://earthsky.org/space/unusual-kilonova-infrared-light-neutron-stars-grb…
Cosmic flashes come in all different sizes
By studying the site of a spectacular stellar explosion seen in April 2020, a Chalmers-led team of scientists have used four European radio telescopes to confirm that astronomy’s most exciting puzzle is about to be solved. Fast radio bursts, unpredictable millisecond-long radio signals seen at huge distances across the universe, are generated by extreme stars called magnetars—and are astonishingly diverse in…
Repeated radio bursts from nearby star suggest such signals are common
The first source of fast radio bursts inside our galaxy is also producing much weaker signals, suggesting FRBs could be common throughout the universe Source: https://www.newscientist.com/article/2259924-repeated-radio-bursts-from-nearby-star-suggest-such-signals-are-common/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Astronomers discover clues that unveil the mystery of fast radio bursts
Fast radio bursts, or FRBs—powerful, millisecond-duration radio waves coming from deep space outside the Milky Way Galaxy—have been among the most mysterious astronomical phenomena ever observed. Since FRBs were first discovered in 2007, astronomers from around the world have used radio telescopes to trace the bursts and look for clues on where they come from and how they’re produced.

Fast radio burst is traced back to its source
For the first time, astronomers have traced a fast radio burst (or FRB) back to its original source – a magnetar. Fast radio bursts, which last mere m… Source: https://www.unexplained-mysteries.com/news/340628/fast-radio-burst-is-traced-back-to-its-source…
We Finally Know What’s Been Making Fast Radio Bursts
Today, researchers are announcing they’ve solved one of the questions that’s been nagging them over the past decade: what exactly produces the weird phenomena known as fast radio bursts (FRBs)? From a report: As their name implies, FRBs involve a sudden blast of radio-frequency radiation that lasts just a few microseconds. We didn’t even know that FRBs existed until 2007 but…
Weird space radio signal tracked to its source for the first time
Strange blasts of radio waves called fast radio bursts have been spotted all over the cosmos, and now astronomers have figured out where one came from Source: https://www.newscientist.com/article/2258758-weird-space-radio-signal-tracked-to-its-source-for-the-first-time/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
