The star, which was 2.5 times brighter than the Sun, left no trace behind
Largest star and 2.5 times brighter than the sun? Nope, that fails the common sense test. Editor gets an F in science.
Other real science sites say it was 2.5 MILLION times as bright as the sun. That makes sense to be seen from 75 million light years.
My partner found the same BIG figure at another site also.
