Astronomers have just watched a supermassive black hole tear apart a gigantic star, releasing a burst of light so intense it rivaled the combined output of hundreds of billions of suns. The event, nicknamed “Whippet,” turned a distant galaxy into a brief cosmic lighthouse and gave researchers an unusually close look at how black holes feed. For a few dazzling moments, the black hole treated a “Super” sized star like a quick snack, and the universe lit up with the consequences.
What made this feast extraordinary was not only its raw power but the level of detail scientists could capture as it unfolded. By tracking the flare from first detection to fading embers, they could watch gravity, magnetism and stellar debris interact in real time, turning a violent death into a laboratory for extreme physics.
The Whippet event and a star brighter than 400 billion suns
At the heart of the story is a transient event that astronomers have labeled the Whippet, a sudden flash that erupted when a supermassive black hole ripped into a massive star. As the star was shredded, the system released as much energy as 400 billion suns, a figure that puts it among the most luminous explosions ever recorded and firmly in the realm of the universe’s most violent outbursts, according to Astronomers. Researchers quickly realized they were not looking at a typical supernova but at a black hole in the act of tearing a star apart and flinging its remains outward in powerful jets.
The star itself has been described as a “Super” sized object, far more massive than the kind of stars that usually fall victim to such encounters. As it spiraled inward, its outer layers were stretched into a glowing stream, while its core was crushed and heated to extraordinary temperatures. Reporting on the flare notes that the outburst was so bright and so fast that it immediately stood out from the background of other cosmic flashes, prompting teams to focus their telescopes on the ‘Super star’ and its black hole predator.
How telescopes caught a black hole in the act
Capturing an event like Whippet requires a global network of instruments that can scan the sky quickly and respond in minutes when something unusual appears. The initial alert came from wide-field surveys that constantly monitor the heavens for new points of light, the same kind of automated searches carried out by facilities such as the Zwicky Transient Facility. Once the flare was flagged, larger observatories swung into action, gathering data across optical, X-ray and radio wavelengths to piece together a full picture of the black hole’s meal.
As the observations accumulated, scientists noticed that the Whippet event did not behave like a standard stellar explosion. Instead of a smooth rise and fall in brightness, the light curve showed rapid changes and an unusually hot, blue spectrum. That pattern led Jan and colleagues to classify Whippet as a Rare and Awe inspiring phenomenon, a kind of extreme transient that sits at the intersection of black hole physics and stellar death. The coordinated campaign turned a fleeting flash into a richly documented case study.
A Luminous Fast Blue Optical Transient with a twist
As I look at the data and the interpretations, what stands out is how Whippet blurs the boundaries between known categories of cosmic explosions. Astronomers suspect that the event might be a Luminous Fast Blue Optical Transient, or LFBOT, a relatively new class of outburst that brightens and fades in days rather than weeks and shines with an intense blue hue. LFBOTs are already rare, but seeing one apparently powered by a black hole shredding a star is rarer still, suggesting that multiple extreme processes can produce similar flashes.
In this case, the star did not simply explode and disperse; it whirlpooled into the black hole, forming a hot, swirling disk and launching jets that carved through surrounding gas. As the material spiraled inward, it created shock waves and high-energy radiation that matched the fast, blue signature associated with LFBOTs. Visualizations of the process show the star stretching into a luminous ribbon, a picture echoed in descriptions that compare the debris to a whirlpool of light, as highlighted when Astronomers described how the star whirlpooled like water down a drain. That combination of rapid evolution, blue color and black hole involvement makes Whippet a crucial test case for theories about these enigmatic transients.
Shock waves, jets and the physics of a cosmic snack
Beyond its brightness, Whippet is valuable because it reveals how black holes can sculpt their surroundings with shock waves and jets. Further investigation of the Whippet flare uncovered a powerful shock wave propagating outward from the central source, a blast front racing through interstellar gas like the bow wave of a supersonic aircraft. The reporting likens the energy involved to the roar of a General Dynamics F-16 jet fighter, a comparison that hints at just how violent the interaction became as stellar debris slammed into the surrounding medium.
Inside that expanding bubble, the black hole’s gravity was still at work, pulling in some of the star’s remains while flinging other fragments outward in narrow, relativistic jets. The team studying the event, including Team members such as R. Michael Rich at the University of California, Los Angeles, or UCLA, argue that this combination of inflow and outflow may explain why the flare was so luminous and so brief. As the jets drilled through the star’s outer layers, they converted gravitational energy into radiation with remarkable efficiency, then faded as the fuel supply dwindled.
Black holes twisting spacetime and snacking on stars
Whippet does not stand alone. It joins a growing list of events that show black holes as dynamic, sometimes messy eaters rather than silent cosmic drains. Earlier this year, Astronomers Watch Black 100 Years Ago, with work led By Cardiff University January, confirmed that material near a black hole can experience frame dragging, where spacetime itself is twisted by the object’s rotation. That effect shapes how gas falls in and how jets are launched, and it likely played a role in focusing the beams that made Whippet so bright.
Other observations show black holes in different feeding moods. NASA, through work highlighted by Jet Propulsion Laboratory Recent studies, has used the Hubble Space Telescope to watch a black hole slowly eat a wandering star, a quieter but still dramatic process that reveals how these objects can devour a bypassing star over time. In another case, astronomers reported the Biggest black-hole outburst ever seen, a Nov event described as a superflare 10 trillion times brighter than the sun, which recorded the death throes of a star and showcased the wild physics at galactic cores, as detailed in Breaking space reports.
From record flares to runaway black holes
Whippet also fits into a broader pattern of increasingly detailed case studies of stellar destruction. In a separate Nov event, astronomers documented a supermassive black hole tearing apart a Huge Star in a Record Flare, with models indicating that the victim likely had between three and 10 solar masses. That work, described in analyses of a Star Torn apart, showed how the brightness and timing of the flare can reveal the star’s mass and the black hole’s appetite. Together with Whippet, it suggests that black holes can produce a spectrum of flares depending on how much material they capture and how efficiently they convert it into light.
In another striking case, a runaway black hole was caught in the act of devouring a star, producing Two distinct radio flares that signaled Tidal disruption and separate, powerful outflows months apart. That pattern shows how even a single encounter can unfold in stages, with the black hole launching multiple bursts as it processes the incoming debris.
