Imagine a cosmic belch so powerful it rivals the energy of a Death Star explosion—but instead of a sci-fi weapon, it’s a supermassive black hole that’s been burping out the remains of a shredded star for four years and counting. This is the mind-bending story of ‘Jetty McJetface,’ a black hole that’s defying all expectations and rewriting the rules of astrophysics.
But here’s where it gets even stranger: while most black holes devour stars in a dramatic but brief spectacle, this one is still brightening years later, leaving scientists scratching their heads. University of Oregon astrophysicist Yvette Cendes and her team are on the case, tracking this bizarre behavior in a new study published in The Astrophysical Journal. Their findings? The black hole’s radio blast could keep climbing until it peaks in 2027—a cosmic light show that’s anything but ordinary.
‘This is really unusual,’ Cendes notes. ‘I’d be hard-pressed to think of anything rising like this over such a long period of time.’ Officially known as AT2018hyz, the black hole earned its playful nickname ‘Jetty McJetface’ as a nod to the internet-famous research vessel Boaty McBoatface. But don’t let the name fool you—this is serious science with a side of humor.
The drama begins with a star wandering too close to a supermassive black hole. Gravity stretches and tears the star apart in a process so extreme it’s called ‘spaghettification.’ Typically, telescopes spot a bright flash of light that quickly fades. But AT2018hyz? It started as a ‘boring, garden-variety event’ in 2018, only to surprise researchers years later with a surge in radio waves. And this is the part most people miss: radio signals tell a different story, hinting at winds or jets slamming into nearby gas.
Cendes, a radio astronomer, uses massive telescopes in New Mexico, South Africa, and beyond to track these signals. Her team’s data reveals a light curve that just keeps climbing—from 1.4 millijanskys in 2019 to a staggering 33.3 millijanskys today. That’s 50 times brighter, with energy output rivaling a gamma-ray burst. To put it in perspective, this black hole is emitting at least a trillion times the energy of the Star Wars Death Star.
But here’s the controversial part: what’s actually causing this? Scientists have two theories. One suggests a delayed, spherical outflow of material moving at one-third the speed of light. The other? A jet launched early but seen from an extreme angle, making it appear weaker until now. Which is it? The answer could reshape our understanding of black hole behavior.
The team is now watching for a turning point, expected in early 2027, that could settle the debate. Meanwhile, Cendes is hunting for other black holes that might pull off similar delayed fireworks. But securing telescope time is a challenge—who expects a years-long encore after an explosion?
This research isn’t just cool science; it’s practical. It’s pushing astronomers to monitor ‘quiet’ events longer, especially with radio and millimeter telescopes. It’s offering new insights into how black holes launch jets and outflows. And if the signal peaks in 2027 as predicted, it will give scientists a rare chance to test their theories in real time.
So, here’s the question for you: Do you think this black hole’s behavior is a one-off oddity, or a sign that we’ve been missing something fundamental about these cosmic monsters? Let’s debate in the comments—the universe is waiting!
