What is the biggest supernova explosion?
supernova SN 2006gy
First observed in September 2006, the supernova SN 2006gy, which occurred in a galaxy called NGC 1260 (240 million light-years away), is the largest and, until confirmation of luminosity of SN 2005ap in October 2007, the most luminous supernova ever observed.

What is the most powerful supernova?
SN2016aps
Now, researchers have announced the discovery of SN2016aps — the brightest, most energetic and probably the most massive supernova ever observed, reports Ryan Mandelbaum for Gizmodo. Supernovae are huge explosions caused by the deaths of stars at least five-times the mass of our sun, according to NASA.
How strong is a Hypernova?
Hypernovas are the most powerful supernova explosions in the universe, 10 to even up to 100 times brighter than a typical supernova.
When was the last black hole?
On the one end, there are the countless black holes that are the remnants of massive stars. Peppered throughout the Universe, these “stellar mass” black holes are generally 10 to 24 times as massive as the Sun….Recent Discoveries.

Can we see supernova explosions?
The light from a supernova can be as bright as an entire galaxy for a short period of time. Some supernovae in our galaxy have been so bright they have been visible during the day! Unfortunately, supernovae visible to the naked eye are rare.
What is the most powerful explosion in the universe?
gamma ray bursts
One of the greatest mysteries of all is what causes gamma ray bursts. These bursts are the most powerful explosions in the Universe and occur about once a day.
How powerful is a Hypernova?
Is it possible that Betelgeuse already exploded?
For all we know, Betelgeuse may have already exploded, but if it has, the light of its supernova hasn’t reached us yet. In Betelgeuse’s case, it’s reached a stage where its puffed-up outer layers are unstable.
