Whippet: A Giant TDE Shocks the Cosmos with 400 Billion Suns of Energy
What is the Whippet and why does it matter? The Whippet is a remarkable tidal disruption event (TDE) that has captured the attention of astronomers worldwide. In a TDE, a star ventures too close to a supermassive black hole and is ripped apart by extreme gravity. The shredded stellar material becomes energized, emitting light and…

Whippet: The Tidal Disruption Event That Blasted 400 Billion Suns’ worth of Energy
What is the Whippet and why it matters The cosmos delivered a jaw-dropping spectacle recently when astronomers observed a tidal disruption event (TDE) nicknamed the “Whippet.” In a TDE, a star wanders too close to a supermassive black hole, gets torn apart by gravity, and some of its stellar debris is flung outward. The Whippet…

Mysterious Blue Cosmic Explosions: Black Holes Shredding Stars and a New Mystery Unfolding
What Are LFBOTs and Why They Shine Blue Astronomers are studying a rare, ultra-bright class of cosmic events known as Luminous Fast Blue Optical Transients (LFBOTs). These explosions stand out because they explode with incredible energy in a short time and emit a distinctly blue glow, unlike most supernovae we have observed. The bright blue…

Blue Blaze: What LFBOTs Reveal About Black Holes Shredding Stars
Introduction: A New Class of Cosmic Light In the vastness of space, some events blaze with a brightness so intense that they momentarily outshine entire galaxies. Among these are Luminous Fast Blue Optical Transients, or LFBOTs, a rare class of stellar explosions characterized by their striking blue color and rapid evolution. Scientists have long debated…
