A team of astronomers has caught a glimpse of a rare cosmic event: a star being consumed by a relatively small black hole. The dramatic event, which unfolded roughly 500 million light-years away, was marked by an extremely bright and unusually fast-fading energy jet.
Dr. Claudia Gutiérrez, from the Spanish Institute of Space Sciences (ICE-CSIC) and the Institute of Space Studies of Catalonia (IEEC), and her colleagues stumbled upon the phenomenon during the Catalina Real-Time transient Survey (CRTS). This ongoing project, which began in 2004, utilizes a network of telescopes in Arizona to monitor the skies for temporary events like supernova explosions and asteroid flybys. The event, dubbed CSS161010, appeared in a galaxy considerably smaller than our Milky Way.
This unique burst of energy peaked within a mere four days before rapidly diminishing in brightness, halving its intensity over the next two and a half days. Further investigation revealed that the CRTS project wasn’t the frist to detect this event; the All-Sky Automated Survey for SuperNovae (ASAS-SN), another sky-scanning project, had already captured it.
Timing Is Everything
The researchers were lucky to spot CSS161010 shortly after its emergence, allowing them to direct other telescopes towards the event. Such fleeting phenomena are notoriously difficult to study due to their rapid advancement and the limited observation time they offer.
Prior to this discovery, scientists had only observed a handful of celestial objects sharing similarities with CSS161010. The nature of these objects remained a mystery until now.
By meticulously analyzing the spectrum of the CSS161010 jet, Gutiérrez’s team identified signatures of hydrogen moving at speeds reaching 10 percent the speed of light. Remarkably, the spectrum bore a striking resemblance to those observed from supermassive black holes residing in active galactic nuclei. Based on their analysis, the researchers concluded that the observed event likely involved a star being consumed by a black hole, not the supermassive variety, but one comparable in size to a star.
As Dr. Gutiérrez and her team continue to study CSS161010, this remarkable observation offers valuable insights into the complex and diverse nature of black holes and their interactions with surrounding stars.

I’m eager to help! 😊
## Star torn Apart by Black Hole: An Interview with Dr.Claudia Gutiérrez
**[Host]:** Welcome back to Archyde Insights. Today we’re discussing a remarkable discovery in the world of astronomy: a star being devoured by a black hole. To shed light on this astounding event,we’re joined by Dr. Claudia Gutiérrez, a leading researcher from the Spanish Instituto de Astrofísica de Canarias. Dr. Gutiérrez, thank you for joining us.
**[Dr. Gutiérrez]:** Thank you for having me.
**[Host]:** Let’s start with the basics. Can you tell us more about what your team observed?
**[Dr. Gutiérrez]:** We detected an incredibly bright and rapidly diminishing jet of energy originating approximately 500 million light-years away. This dramatic event signals the consumption of a star by a relatively small black hole. Though these events occur, witnessing them directly is exceptionally rare.[[1](https://www.nature.com/articles/d44151-024-00177-6)]
**[Host]:** This sounds unbelievably powerful. What makes this particular event so unique?
**[Dr. Gutiérrez]:** The remarkable speed at which the energy jet faded is what sets this observation apart. This rapid decline indicates the relatively small size of the black hole devouring the star. Smaller black holes have a stronger gravitational pull proportionate to their size, leading to a quicker and more intense consumption process.
**[Host]:** You mentioned this event is rare. Why is it so uncommon to observe a star being consumed by a black hole?
**[dr. Gutiérrez]:** These events occur in distant galaxies, making direct observation extremely challenging. Additionally, the timescale of these occurrences is relatively short, requiring precise timing and observation techniques to capture them.
**[Host]:** What are the implications of this discovery for our understanding of the universe?
**[Dr.Gutiérrez]:** This observation provides valuable insights into the dynamics of black hole growth and the interactions between black holes and stars in galactic environments.It also helps us refine our models of how these powerful objects evolve over time.
**[Host]:** Dr. Gutiérrez, thank you so much for sharing your expertise and illuminating this exciting discovery for our viewers.
**[Dr. Gutiérrez]:** It was my pleasure.
