Unveiling the Secrets of our Galaxy’s Supermassive Black Hole

July 15th, 2024

Researchers use X-ray observations from NuSTAR to identify nine previously undetected flares from Sagittarius A*, the relatively dormant supermassive black hole at the center of the Milky Way. X-ray echoes from a nearby molecular cloud reveal that 200 years ago the black hole was 10,000 times more active than it is today.

Brightest Cosmic Explosion Ever Detected Had Other Unique Features

June 8th, 2023

When scientists detected the gamma-ray burst known as GRB 221009A on Oct. 9, 2022, they dubbed it the brightest of all time, or BOAT. Most gamma-ray bursts occur when the core of a star more massive than our Sun collapses, becoming a black hole. These events regularly release as much energy in a few minutes as our Sun will release in its entire lifetime.

NASA Study Helps Explain Limit-Breaking Ultra-Luminous X-Ray Sources

April 6th, 2023

In a recent study published in The Astrophysical Journal, researchers report a first-of-its-kind measurement of a ULX taken with NASA's Nuclear Spectroscopic Telescope Array (NuSTAR). The finding confirms that these light emitters are indeed as bright as they seem and that they break the Eddington limit.
