The scientists are now talking with colleagues who build gamma-ray telescopes to judge the feasibility of launching one or a fleet of such telescopes to cover 100% of the sky 24/7 and be assured of catching any gamma-ray burst.

If this had been a short gamma-ray burst, caused by two colliding neutron stars, the collision would have created gravitational waves and have an afterglow in X-rays and visible light.

In this case, had the observations been performed even just a day later, there would not have been such strong proof that this was indeed a magnetar and not a gamma-ray burst.

"In fact, this was one of the narrowest jets seen for a gamma-ray burst so far, which gives us a hint as to why the afterglow appeared as bright as it did. There may be other factors responsible as well, a question that researchers will be studying for years to come."

The massive explosion unleashed a gamma-ray burst, GRB230307A, the second brightest in 50 years of observations and about 1,000 times brighter than a typical gamma-ray burst.
