Scary Barbie – The Largest Cosmic Explosion

May 13, 2023

Astronomers recently made an extraordinary discovery, identifying the largest cosmic explosion ever observed. This colossal fireball, affectionately nicknamed “Scary Barbie,” has captivated scientists and enthusiasts alike.

Unveiling the Magnitude: 100 Times Larger Than Our Solar System

The scale of this cosmic explosion is mind-boggling. Comparisons indicate that the fireball is a staggering 100 times larger than our Solar System. To comprehend the sheer enormity of Scary Barbie is to marvel at the wonders of the universe.

A Phenomenon Beyond Three Years

While most supernovae last only a few months before fading away, Scary Barbie has endured for more than three years, defying conventional expectations. This remarkable longevity has piqued the curiosity of astronomers, compelling them to further investigate this unprecedented event.

The Brightest of All Time: BOAT vs. Scary Barbie

The gamma-ray burst named BOAT (Brightest Of All Time) made headlines for its luminosity; however, Scary Barbie has outshone it in terms of duration. Although BOAT was brighter, its short-lived intensity pales in comparison to the sustained brilliance of Scary Barbie.

An Unfathomable Distance: 8 Billion Light Years Away

AT2021lwx, the explosion’s scientific designation, originates from an astonishing distance of approximately 8 billion light years away. This reveals that the event occurred when the universe was approximately 6 billion years old, offering valuable insights into the cosmos during its early stages.

Unraveling the Mystery: A Supermassive Black Hole’s Role

Astronomers have postulated a captivating explanation for this extraordinary explosion. It is believed that a supermassive black hole played a pivotal role in disrupting a vast cloud of gas, potentially thousands of times larger than our sun. This violent encounter between the cloud and the black hole resulted in the awe-inspiring display we observe today.

Detection and Recognition: Zwicky Transient Facility

The Zwicky Transient Facility in California first detected AT2021lwx, setting in motion an array of research and observation. This state-of-the-art facility’s meticulous monitoring allowed astronomers to witness the birth and evolution of Scary Barbie, adding to our understanding of these rare cosmic events.

Radiance That Defies Comparison: 2 Trillion Times Brighter Than the Sun

One can hardly fathom the immense brightness emitted by Scary Barbie. Estimates suggest that this cosmic explosion shines approximately 2 trillion times brighter than our Sun, a truly awe-inspiring revelation that accentuates the unprecedented nature of this phenomenon.

Not a Tidal Disruption Event: Exploring Alternatives

While scientists explored multiple possible explanations, a tidal disruption event—when a star is torn apart by a supermassive black hole—did not align with the characteristics of Scary Barbie. Its luminosity surpassed that of such events by a factor of three, steering researchers toward other compelling hypotheses.

The Quasar Comparison: Flickers vs. Sustained Brilliance

In attempting to find a somewhat comparable cosmic event, astronomers turned to quasars. However, unlike the intermittent fluctuations in brightness exhibited by quasars, Scary Barbie emerged suddenly and has continued to blaze with unwavering intensity for over three years. This distinction further underscores the uniqueness of this cosmic explosion.
