Hypernovae are ultra-powerful supernovae occurring when massive stars collapse, releasing 100 times more energy than normal supernovae. These explosions produce black holes and gamma-ray bursts, shaking the very fabric of the cosmos.

Gamma-ray bursts are the most energetic explosions, emitting intense radiation in seconds. Some bursts release as much energy as the Sun will in its entire lifetime, making them the brightest events ever recorded in space.

The biggest explosion of all, the Big Bang, created the universe around 13.8 billion years ago. It expanded space from a singularity, forming all matter, energy, and cosmic structures we see today, continuing to shape our existence.

SN 1998bw was a rare supernova linked to a gamma-ray burst. This explosion, occurring 120 million light-years away, was one of the most energetic ever observed, challenging scientists’ understanding of supernovae and high-energy astrophysics.

SN 1006 exploded in the year 1006 and became so bright it was visible in daylight. This Type Ia supernova, 7,200 light-years away, left behind a vast remnant still expanding today, marking one of the most luminous stellar deaths in history.

A collision between Andromeda and another galaxy triggered immense shockwaves, setting off powerful bursts of star formation and radiation. This event reshaped Andromeda’s structure, showing how galactic interactions fuel cosmic destruction.

Some quasars release colossal bursts of energy as matter falls into their supermassive black holes. These outbursts can outshine entire galaxies, expelling energy equivalent to trillions of Suns and shaping the evolution of surrounding space.

This explosion, detected in the Ophiuchus galaxy cluster, was the largest known cosmic explosion since the Big Bang. It released energy equivalent to hundreds of millions of supernovae, carving a massive void in intergalactic gas.

When two neutron stars collide, they unleash titanic explosions called kilonovae. These events generate heavy elements like gold and platinum, sending gravitational waves rippling through space and creating spectacular bursts of light.

Eta Carinae, one of the most massive stars, erupted in the 19th century in a colossal explosion called a supernova impostor event. Though it didn’t fully explode, the eruption was so powerful it temporarily became one of the brightest stars in the sky.
