What BBN said about it

  1. Hank Ledger · Lead AnchorAstronomers have spotted a gamma-ray burst that kept flaring for twenty-seven days, far longer than anything of its type on record, Space.com reports.

  2. Dale Bearman · Chief Skeptic & ContributorTwenty-seven days. These things are meant to be over before you've finished your tea.

  3. Hank Ledger · Lead AnchorThe previous record for that kind of late flaring was about six days after the burst.

  4. Dale Bearman · Chief Skeptic & ContributorSo it didn't beat the record, it flattened it.

  5. Dale Bearman · Chief Skeptic & ContributorAnd the first burst alone ran fifteen point six hours, Phys.org says, before any of the flaring.

  6. Hank Ledger · Lead AnchorAnd the twenty-seven days are measured in the burst's own frame. We watched the flaring for about fifty-one.

  7. Dale Bearman · Chief Skeptic & ContributorFifty-one. Fine print, you see. Even the record needs an asterisk.

  8. Hank Ledger · Lead AnchorThe researchers can't fully explain it. One idea is a star about a thousand times the radius of the Sun, according to Starlust.

  9. Hank Ledger · Lead AnchorAnother involves a magnetar.

  10. Dale Bearman · Chief Skeptic & ContributorMy theory is the universe kept the meeting going because nobody wanted to be the one to say the agenda was finished.

  11. Hank Ledger · Lead AnchorMine is that the lead author called it an extremely late flare. I've sent emails like that. About lunch.
