“It is the only X-ray telescope sensitive enough to detect the fainter X-ray background light between the bursts,” Hernández-García explains. By measuring how dim Ansky became between each ...

A sudden, record-breaking gamma-ray burst lit up the cosmos—leaving scientists stunned and searching for answers. the powerful flash, brighter than anything seen before, could change what we know ...

Before this research, scientists didn't recognize that some nearby gamma-ray bursts are also part of this massive structure. The finding is extraordinary because the Hercules-Corona Borealis Great ...

It is the only X-ray telescope sensitive enough to detect the fainter X-ray background light between the bursts. With XMM-Newton we could measure how dim Ansky gets, which enabled us to calculate ...
