Star Breaks Free From Supermassive Black Hole—And It’s Not Done Yet


A star narrowly escapes the deadly grip of a supermassive black hole, defying the odds.




In a remarkable twist of fate, a star has defied the odds by escaping the destructive grasp of a supermassive black hole, only to return for a second encounter. This rare event, captured by astronomers, challenges long-standing theories about how black holes interact with stars.

A Star That Defied The Odds

The cosmic drama began when a distant supermassive black hole tried to devour a star from a galaxy millions of light-years away. Instead of succumbing to the black hole’s gravitational forces, the star managed to escape, sparking interest among researchers. The first clue came in the form of a flare, a sudden burst of light signaling the star’s first brush with destruction. Astronomers were surprised when, about 700 days later, a second flare appeared, nearly identical to the first.

The phenomenon was officially named AT 2022dbl, and the team behind the discovery was quick to dismiss the possibility that two different stars were involved. Instead, they concluded that the flares were caused by the same star enduring two separate “bites” from the black hole.

What Are Tidal Disruption Events (TDEs)?

To understand the significance of this discovery, it’s important to know about tidal disruption events (TDEs), a phenomenon that occurs when a star ventures too close to a supermassive black hole. Black holes, which reside at the centers of most large galaxies, have such strong gravitational pulls that anything that crosses a certain threshold gets pulled apart.

As a star gets too close, the black hole’s gravity stretches and tears it apart in a process known as spaghettification. Some of the star’s material falls into the black hole, while the rest is flung out into space, often producing spectacular flares of light.

For years, scientists have observed TDEs, but these events have typically been seen as one-time occurrences, with stars destroyed in a single dramatic event. The flares that follow such disruptions can last weeks to months, illuminating the region around the black hole. But recently, some TDEs have exhibited behavior that didn’t quite match expectations.

A Star’s Return: What’s Next?

AT 2022dbl raises the possibility that not all TDEs result in the complete destruction of the star. Instead, it suggests that some black holes may prefer a slower, more drawn-out “meal” rather than immediately consuming their prey. If this star survived its second encounter, it could return for a third round of flares, continuing the cosmic spectacle.

Researchers now eagerly await the next flare, which they expect in early 2026. If a third flare appears, it would confirm the idea that the star wasn’t fully destroyed during its second encounter, leading to a reevaluation of the nature of tidal disruption events.

However, if no flare appears, it would indicate that the star met its end during the second round, though the similarities between the first two flares would suggest that partial and full disruptions might look the same. This would provide strong evidence that not all TDE flares are caused by total stellar destruction, a discovery that could change how scientists interpret these events.

"Explore the Fourth Dimension"

Fourth Dimension   The fourth dimension is a fascinating concept that has captured the imaginations of scientists, mathematicians, and artists for centuries. Unlike our three-dimensional world, which is limited by the linear flow of time, the fourth dimension is a realm of space and time that exists beyond our everyday experience. One way to visualize the fourth dimension is through the use of a hypercube, also known as a tesseract. A hypercube is a cube within a cube, with additional lines and edges connecting the vertices of the two cubes. It's impossible to construct in our three-dimensional world, but it provides a glimpse into what the fourth dimension might look like. Another way to understand the fourth dimension is through the concept of a wormhole, a theoretical passage through space-time that connects two distant points in the universe. A wormhole is like a shortcut through the fabric of space-time, allowing us to travel vast distances in an instant. While there is no de...

Physicists observe a new form of magnetism for the first time

MIT physicists have demonstrated a new form of magnetism that could one day be harnessed to build faster, denser, and less power-hungry " spintronic " memory chips. The new magnetic state is a mash-up of two main forms of magnetism: the ferromagnetism of everyday fridge magnets and compass needles, and antiferromagnetism, in which materials have magnetic properties at the microscale yet are not macroscopically magnetized. Now, the MIT team has demonstrated a new form of magnetism , termed "p-wave magnetism." Physicists have long observed that electrons of atoms in regular ferromagnets share the same orientation of "spin," like so many tiny compasses pointing in the same direction. This spin alignment generates a magnetic field, which gives a ferromagnet its inherent magnetism. Electrons belonging to magnetic atoms in an antiferromagnet also have spin, although these spins alternate, with electrons orbiting neighboring atoms aligning their spins antiparalle...

Quantum Tunneling Breakthrough: Technion Scientists Move Atoms With Precision

In a groundbreaking experiment at the Technion Faculty of Physics , researchers demonstrated the transfer of atoms via quantum tunneling using optical tweezers. This novel method, which strategically avoids trapping atoms in the middle tweezer, represents a notable stride toward innovative quantum technologies. Quantum Tunneling in Optical Tweezers A new experiment at the Technion Faculty of Physics demonstrates how atoms can be transferred between locations using quantum tunneling with optical tweezers. Led by Prof. Yoav Sagi and doctoral student Yanay Florshaim from the Solid State Institute, this research was published recently in Science Advances. The experiment relies on optical tweezers , a powerful tool that uses focused laser beams to trap and manipulate tiny particles like atoms, molecules, and even living cells. Here’s how it works: when light interacts with matter, it creates a force proportional to the light’s intensity. This force, though too weak to impact larger objects,...
