Unveiling Cosmic Wonders: How Spotify-like AI Discovered a New Supernova Amidst a Star’s Attempt to Devour a Black Hole

Scientists may have discovered a new type of supernova using a unique AI system. This powerful tool, inspired by Spotify, scans the skies for unusual activity. Recently, it detected signs of a massive star potentially exploding while trying to consume a black hole.

The event, named SN 2023zkd, was identified in July 2023 by the Zwicky Transient Facility at California’s Palomar Observatory. The AI behind this discovery helps pinpoint cosmic events by analyzing light patterns, much like how Spotify recommends new music. This capability allowed researchers to catch the signs of the supernova early, leading to vital observations before and during the explosion.

Study leaders Alex Gagliano, a researcher at the Institute for AI and Fundamental Interactions, and Ashley Villar from the Harvard-Smithsonian Center for Astrophysics, highlighted the importance of these early alerts. The quick notifications enabled multiple observatories to gather valuable data across various wavelengths. This teamwork is crucial for understanding how supernovas develop and fade.

The AI, called Lightcurve Anomaly Identification and Similarity Search (LAISS), found unusual brightness in the weeks leading up to the explosion. Gagliano noted that this suggests the interaction between the star and black hole was complex. They propose that the massive star’s gravitational pull might have caused it to explode.

Interestingly, the AI’s analysis revealed that the star had retained some outer material before it blew up. “This finding hints that interactions in binary systems could be more complicated than we thought,” said Gagliano. Understanding these events can help researchers better predict future supernova explosions.

The light pattern of SN 2023zkd exhibited strange behavior, first brightening, then fading, and finally brightening again—indicative of potential interactions with surrounding materials. This brightening was attributed to the shockwave from the explosion colliding with lower-density gas nearby.

In terms of technology, AI like LAISS is revolutionizing astronomy. It allows scientists to discover rare cosmic events without relying solely on luck. “Without the AI, we would have missed crucial details about the black hole’s presence and the disk of material around the star,” Gagliano stated.

This research underscores the growing synergy between AI and astronomy, allowing quicker and more precise discoveries. You can read more in the recent study published in The Astrophysical Journal.
