It also had the brightest UVOT afterglow ever recorded once corrected for extinction. [46] It had the largest amount of energy ever recorded in the TeV range, [47] and had the most energetic photons ever recorded for a GRB, peaking at 18 TeV. [25] [20] The burst was ten times brighter than any previous GRB detected by the Swift mission. [48]
South Carolinians may soon have the chance to view a spectacular stellar event that happens once a generation. According to NASA, the T Coronae Borealis, nicknamed the Blaze Star, lies 3,000 light ...
A rare cosmic eruption is expected to occur in the Milky Way in the coming months — an outburst so bright that a “new” star will seemingly appear for a short time in the night sky.
NASA has predicted that a "once-in-a-life-time" star explosion -- or nova -- will be visible to the naked eye sometime this summer.
First long GRB from a binary neutron star merger [11] GRB 221009A: R.A. 19 h 13 m 03.48 s Decl. 19° 46′ 24.6″ z = 0.151: Swift: One of the closest GRB and was the most energetic and brightest GRB ever recorded, deemed the "B.O.A.T.", or Brightest Of All Time. It had 18 TeV, a record. GRB 230307A: Fermi Second only to GRB 221009A in terms ...
At 15:44:06 UT on 7 Mar 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230307A . [6] at the same time, the Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor light curve shows a roughly fast rise and exponential decay (FRED) shape with a possible precursor, with a total duration of ~100 sec. [7] At 2023-03-07T15:44:09Z UT (Solar Orbiter onboard ...

A number of close or well-known stars have been identified as possible core collapse supernova candidates: the high-mass blue stars Spica and Rigel, [238] the red supergiants Betelgeuse, Antares, and VV Cephei A; [239] [240] [241] the yellow hypergiant Rho Cassiopeiae; [242] the luminous blue variable Eta Carinae that has already produced a ...
