Key aspects of this event:
"Boring" to "Bursting":
The black hole was previously inactive for decades, with no noticeable emission, before suddenly becoming highly active.
Quasiperiodic Eruptions (QPEs):
The black hole is emitting intense bursts of X-rays at regular intervals.
Unprecedented X-ray Flares:
The bursts are longer and more luminous than previously observed QPEs, according to a team at the Massachusetts Institute of Technology.
Active Galactic Nucleus:
The black hole's activity has classified the central region of the galaxy as an active galactic nucleus.
Real-Time Observation:
Astronomers are observing the black hole's evolution in real-time, as reported by MSN providing a unique opportunity to study black holes and their behavior.
Location:
SDSS1335+0728 is a distant galaxy located about 300 million light-years away in the constellation Virgo.
