The most energetic photon associated with a gamma-ray burst survived a journey that, according to standard models, it could not survive.
It ran on October 9, 2022 when the Swift and Fermi space telescopes captured the brightest gamma-ray burst ever recorded. Astronomers, with such a taste for resounding nicknames, named it GRB 221009A, although today it is known mostly by its nickname: Boat, the name "most [...]
In 2022, astronomers discovered an absurdly bright and long-lasting gamma-ray burst, GRB 221009A, nicknamed "BOAT," or "Brightest of All Time."
To answer strange questions, sometimes it is necessary to get strange answers (reasonably). In 2022, astronomers detected an explosion of absurdly bright and lasting gamma rays, the GRB 221009A, nicknamed "Boat", by "Brightest of All Time", the brightest ever (really). The rain of photons was so old and so powerful that, in theory, it should not have arrived on Earth. And yet it did. But how? In an article published on Tuesday in Physical Review…
