14 lis 2023 · The artistic impression depicts the effect of a powerful blast of gamma rays that provoked a significant disturbance in our planet’s ionosphere. This is the result of a gamma-ray burst (GRB) from a star’s supernova explosion, in a galaxy almost two billion light-years away.
Explanation: Gamma-ray burst GRB 221009A likely signals the birth of a new black hole, formed at the core of a collapsing star long ago in the distant universe. The extremely powerful blast is depicted in this animated gif constructed using data from the Fermi Gamma Ray Space Telescope.
13 wrz 2024 · Hundreds of gamma-ray bursts (GRBs) have been recorded as part of an enormous global effort so extensive it 'rivals the catalog of deep-sky objects created by Messier 250 years ago',...
23 wrz 2024 · Astronomers have cataloged a stunning treasure trove of over 500 of the universe's most powerful explosions. These so-called gamma-ray bursts, or GRBs, are so energetic that if just one of...
17 sie 2024 · The GRB 221009A burst, which occurred on October 9, 2022, dubbed the brightest of all time (BOAT), was the strongest gamma-ray burst ever recorded. Observations made by the Swift-BAT...
26 lip 2021 · Each jet drills through the star, producing a pulse of gamma rays – the highest-energy form of light – that can last up to minutes. Following the burst, the disrupted star then rapidly expands as a supernova.
7 gru 2022 · A classic short gamma-ray burst begins with two orbiting neutron stars, the crushed remnants of massive stars that exploded as supernovae. As the stars circle ever closer, they strip neutron-rich material from each other.
