Key Facts About the Detection of the Largest Flare from a Distant Black Hole

• Largest flare detected from a supermassive black hole 10 billion light-years away.
• First observed in 2018.
• Responsible for the brightest flare ever recorded.
• Linked to a tidal disruption event (TDE) from star consumption.
• TDE occurs when a star is torn apart by a black hole's gravity.
• Flare intensified by 40 times over several months.
• Peaked at 30 times the brightness of previous flares.
• Released energy equivalent to 10 trillion suns.
• 2023 data from Keck Observatory confirmed intense energy.
• Ruled out the possibility of a supernova.
• Star consumed was 30 times the mass of the Sun.
• Significantly larger than stars in previous TDEs.
• Black hole's gravity causes cosmological time dilation.
• Time dilation allows researchers to observe events at a slower pace.
• Offers insights into black hole dynamics.
• Recent discoveries highlight the significance of tidal disruption events.
