Some of the universe's most extreme explosions leave behind almost no trace. The original explosion is unseen, but our observations can capture the long-lived echo it leaves behind as the shock front ...

Astronomers have detected the radio afterglow of a powerful space explosion that went unseen, possibly an orphan gamma-ray burst or a rare blackhole event 1.7 billion light-years away ...

A newly detected X-ray transient may reveal the first direct evidence of an intermediate-mass black hole consuming a white dwarf. A newly observed cosmic outburst is giving astronomers a rare glimpse ...

A mysterious cosmic explosion linked to gravitational waves may reveal a previously unknown type of supernova event - a ...

It was only last October that telescopes spotted a gamma ray burst—caused by the collapse of a black hole —that was so powerful astronomers quickly dubbed it BOAT, for “Brightest of all Time.” That ...

NASA has detected a precursor or progenitor to a supernova for the first time – and it's all thanks to old photos. Researchers have now been able to study some of a supernova's progression by ...

The James Webb Space Telescope spots evidence of a stellar explosion that could help solve the cosmic mystery of "missing red supergiants." ...

Caltech astronomer Mansi Kasliwal and her colleagues were not expecting to chase a mystery that blurred the line between a supernova and a kilonova. Yet that is where the evidence has led after an ...

A strange cosmic blast that lit up the sky in two distinct acts is forcing astronomers to rethink how stars live and die. The event, tagged AT2025ulz, appears to be the first known case where a ...
