Astronomers have found the brightest explosion in the universe

Astrophysicists stumble upon an explosion brighter than most supernovae, challenging our understanding of the universe's brightest events.


Outshining the stars, a novel celestial explosion has seized the attention of the global astronomy community. Labelled as the “Luminous Fast Cooler” (LFC), this new discovery surpasses even the most brilliant supernovae, prompting researchers to dive deep into its mysterious origins.

For a long time, supernovae held the title of the universe’s brightest explosions, resulting from stars depleting their fuel and subsequently erupting in a radiant explosion of light and energy. Their frequency and brightness have made them an observational cornerstone. However, this newly discovered LFC might be the new contender for the crown.


During their routine data analysis from the ATLAS network of robotic telescopes, researchers stumbled upon this extraordinary explosion. As they tracked its evolution, they recognized that its characteristics diverged significantly from a typical supernova. Not only was the LFC exceptionally bright, but it also emanated from an unexpected location—a galaxy teeming with sun-sized stars, an unlikely spot for supernovae.


Unprecedented Brightness and Speed

What sets the LFC apart is its rapid progression. Unlike a supernova, which reaches its pinnacle in about 20 days and then slowly diminishes, the LFC peaks in just 15 days and almost vanishes within a month.

Dumbfounded by this discovery, the team delved into historical telescope data. Their pursuit bore fruit as they identified two similar past occurrences—one from 2020 and another from 2009. These revelations cemented the notion of the LFC as a distinct type of explosion, the origins of which remain enigmatic.

While the precise causes of these LFC events remain under wraps, the researchers have theories. One possibility is the catastrophic collision between a star and a black hole. But this is merely a hypothesis, and thorough investigations are crucial to unravel the true nature of these spectacular explosions.
