Gamma-ray burst is one of the brightest in decades
A gamma-ray burst (GRB) that has confounded astronomers is one of the brightest cosmic light shows in the past 20 years. Although the cosmic explosion first appeared inexplicably weak, researchers now believe it actually shot about one billion years’ worth of solar energy into the cosmos through a beam no thicker than a pencil. “We see hundreds of GRBs every year, but the oddballs are the most informative ones,” said Roberto Ricci, a radioastron…
This gamma-ray burst emitted an amount of energy comparable to the amount of energy the Sun produces in a billion years.
When NASA's Fermi Space Telescope recorded the GRB 260310A explosion on March 10, it seemed too weak to impress.
A comparatively weak gamma flash from March 2026 left behind one of the brightest aftershocks ever observed. The light curves suggest that the Earth did not look directly into the bundled matter beam of the explosion. A renewed lightening in the X-ray could also indicate a particularly energetic core of this jet. Rome (Italy). When a massive star at the end of its [...] The post Weak gamma flash left one of the brightest aftershocks ever observe…
