'There's a reasonable chance this is the brightest gamma-ray burst to hit Earth since human civilization began.'
"If it's there, it's very faint," Andrew Levan, a professor of astrophysics at Radboud University in the Netherlands, said in a."We plan to keep looking, but it's possible the entire star collapsed straight into the black hole instead of exploding."GRB jets tend to be relatively narrow, so most of them don't sweep over Earth. But these astrophysical events, though extreme, are common enough to be observed in bulk.
"When you compare the energy in this jet, it's very similar to the energy of jets we've seen in other GRBs," Kate Alexander, an assistant professor of astronomy at the University of Arizona, said during Tuesday's press conference.

Insight-HXMT and GECAM-C observations of the brightest-of-all-time GRB 221009AGRB 221009A is the brightest gamma-ray burst ever detected since the discovery of this kind of energetic explosions. However, an accurate measurement of the prompt emission properties of this burst is very challenging due to its exceptional brightness. With joint observations of \textit{Insight}-HXMT and GECAM-C, we made an unprecedentedly accurate measurement of the emission during the first $\sim$1800 s of GRB 221009A, including its precursor, main emission (ME, which dominates the burst in flux), flaring emission and early afterglow, in the hard X-ray to soft gamma-ray band from $\sim$ 10 keV to $\sim$ 6 MeV. Based on the GECAM-C unsaturated data of the ME, we measure a record-breaking isotropic equivalent energy ($E_{\rm iso}$) of $\bf \sim 1.5 \times 10^{55}$ erg, which is about eight times the total rest-mass energy of the Sun. The early afterglow data require a significant jet break between 650 s and 1100 s, most likely at $\sim950$ s from the afterglow starting time $T_{AG}$, which corresponds to a jet opening angle of $\sim {0.7^\circ} \ (η_γn)^{1/8}$, where $n$ is the ambient medium density in units of $\rm cm^{-3}$ and $η_γ$ is the ratio between $γ$-ray energy and afterglow kinetic energy. The beaming-corrected total $γ$-ray energy $E_γ$ is $\sim 1.15 \times10^{51} \ (η_γ n)^{1/4}$ erg, which is typical for long GRBs. These results suggest that this GRB may have a special central engine, which could launch and collimate a very narrowly beamed jet with an ordinary energy budget, leading to exceptionally luminous gamma-ray radiation per unit solid angle. Alternatively, more GRBs might have such a narrow and bright beam, which are missed by an unfavorable viewing angle or have been detected without distance measurement.
