Scientists have recorded the most powerful burst of energy in space ever observed.

Scientists have recorded an unprecedented burst of gamma rays (GRB), which at some wavelengths looked brighter than any similar burst of energy observed before. The burst was named GRB 221009A and was first detected by the Fermi Gamma Ray Space Telescope, a joint project between NASA and the US Department of Energy, as well as the space agencies of France, Italy, Japan and Sweden… Detail: https://bitcoingrandee.com/news NEWS

In 2017, an extremely strong burst of radiation called a gamma ray burst (top panel) was detected from a galaxy 🌌 (NGC 4993) far far away. . Located 144 light years away, NGC 4993 contained two high density neutron stars (bottom panels) that merged together. Not only did the merger result in the subsequent release of gamma rays, but also sent ripples in spacetime that reached Earth as gravity waves. . Gamma ray bursts are the most energetic events in the known universe. It is thought that one occurring in the Milky Way and pointing directly at Earth could cause mass extinctions. . Thus, all known gamma ray bursts so far have been detected outside of our galaxy. .

Moving Closer to Understanding of Universe's Most Powerful Explosions

Good fortune and cutting-edge scientific equipment have allowed scientists to observe a Gamma Ray Burst jet with a radio telescope and detect the polarization of radio waves within it for the first time - moving us closer to an understanding of what causes the universe's most powerful explosions. Gamma Ray Bursts (GRBs) are the most energetic explosions in the universe, beaming out mighty jets which travel through space at over 99.9% the speed of light, as a star much more massive than our Sun collapses at the end of its life to produce a black hole. The study was published in Astrophysical Journal Letters.

CLICK IMAGE TO ENLARGE Studying the light from Gamma Ray Burst jets as we detect it travelling across space is our best hope of understanding how these powerful jets are formed, but scientists need to be quick to get their telescopes into position and get the best data. The detection of polarized radio waves from a burst's jet, made possible by a new generation of advanced radio telescopes, offers new clues to this mystery. The light from this particular event, known as GRB 190114C, which exploded with the force of millions of Suns' worth of TNT about 4.5 billion years ago, reached NASA's Neil Gehrels Swift Observatory on Jan 14, 2019. A rapid alert from Swift allowed the research team to direct the Atacama Large Millimeter/Sub-millimeter Array (ALMA) telescope in Chile to observe the burst just two hours after Swift discovered it. Two hours later the team was able to observe the GRB from the Karl G. Jansky Very Large Array (VLA) telescope when it became visible in New Mexico, USA. Combining the measurements from these observatories allowed the research team to determine the structure of magnetic fields within the jet itself, which affects how the radio light is polarized. Theories predict different arrangements of magnetic fields within the jet depending on the fields' origin, so capturing radio data enabled the researchers to test these theories with observations from telescopes for the first time. The research team, from the University of Bath, Northwestern University, the Open University of Israel, Harvard University, California State University in Sacramento, the Max Planck Institute in Garching, and Liverpool John Moores University discovered that only 0.8% of the jet light was polarized, meaning that jet's magnetic field was only ordered over relatively small patches - each less than about 1% of the diameter of the jet. Larger patches would have produced more polarized light. These measurements suggest that magnetic fields may play a less significant structural role in GRB jets than previously thought. This helps us narrow down the possible explanations for what causes and powers these extraordinary explosions. First author Dr. Tanmoy Laskar, from the University of Bath's Astrophysics group, said: "We want to understand why some stars produce these extraordinary jets when they die, and the mechanism by which these jets are fuelled - the fastest known outflows in the universe, moving at speeds close to that of light and shining with the incredible luminosity of over a billion Suns combined. "I was in a cab on my way to O'Hare airport in Chicago, following a visit with collaborators when the burst went off. The extreme brightness of this event and the fact that it was visible in Chile right away made it a prime target for our study, and so I immediately contacted ALMA to say we were going to observe this one, in the hope of detecting the first radio polarization signal. "It was fortuitous that the target was well placed in the sky for observations with both ALMA in Chile and the VLA in New Mexico. Both facilities responded quickly and the weather was excellent. We then spent two months in a painstaking process to make sure our measurement was genuine and free from instrumental effects. Everything checked out, and that was exciting. Dr. Kate Alexander, who led the VLA observations, said: "The lower frequency data from the VLA helped confirm that we were seeing the light from the jet itself, rather than from the interaction of the jet with its environment." Dr. Laskar added: "This measurement opens a new window into GRB science and the studies of energetic astrophysical jets. We would like to understand whether the low level of polarization measured in this event is characteristic of all GRBs, and if so, what this could tell us about the magnetic structures in GRB jets and the role of magnetic fields in powering jets throughout the universe." Professor Carole Mundell, Head of Astrophysics at the University of Bath, added: "The exquisite sensitivity of ALMA and rapid response of the telescopes has, for the first time, allowed us to swiftly and accurately measure the degree of polarization of microwaves from a GRB afterglow just two hours after the blast and probe the magnetic fields that are thought to drive these powerful, ultra-fast outflows." The research team plans to hunt for more GRBs to continue to unravel the mysteries of the biggest explosions in the universe. Read the full article

lol no, this is about two of the smallest-mass mergers found in LIGO operating run 3. they happened 18mos ago, and even the largest ones involve detecting movement less than the width of a proton. these two were also like 280-300 megaparsecs away. this could happen in our own galaxy and still not affect us much, i think (there's little to no risk of cosmic radiation or whatever)

they are of interest because a neutron star/black hole merger had never previously been observed (and still hasn't been observed optically, only gravitationally), so the amount of these events that were found in O3 (several!) is revising the estimate of how much this type of merger can occur (neutron stars and black holes probably form in more similar environments than previously thought)

the g in gcn is actually for gammaray and i forget what the other two are. communications network? it's the realtime mailing list for gamma ray burst transient events, and gravitational wave events got added to the same mailing list when LIGO started

oh it's "circular network" so "gcn circulars" is really "gammarayburst circular network circulars." why they didn't call them GRB circulars, i don't know

the paper says they are unable to place any constraints on the spin, tidal deformation, or gender of either of the neutron stars. the black holes have some spin constraints

unmodeled event detected at LIGO yesterday and a massgap event today. somebody at the university of paris suggested the unmodeled event may be consistent with a core collapse supernova, which is, wildly, observable as light from (faster than light) cherenkov radiation for the brief period of milliseconds during collapse, when the supernova emits electron antineutrinos

Regrann from @nasahubble - Don’t be fooled! The cosmic swirl of stars in this Hubble image may seem tranquil and unassuming, but this spiral galaxy, known as ESO 580-49, actually displays some explosive tendencies. In October of 2011, a cataclysmic burst of high-energy gamma-ray radiation — known as a gamma-ray burst, or GRB — was detected coming from the region of sky containing ESO 580-49. Astronomers believe that the galaxy was the host of the GRB, given that the chance of a coincidental alignment between the two is roughly 1 in 10 million. At a distance of around 185 million light-years from Earth, it was the second-closest gamma-ray burst (GRB) ever detected. Gamma-ray bursts are among the brightest events in the cosmos, occasionally outshining the combined gamma-ray output of the entire observable Universe for a few seconds. The exact cause of the GRB that probably occurred within this galaxy, cataloged as GRB 111005A, remains a mystery. Several events are known to lead to GRBs, but none of these explanations appear to fit the bill in this case. Astronomers have therefore suggested that ESO 580-49 hosted a new type of GRB explosion — one that has not yet been characterized.
