Bright Transient Survey Bot (BTSbot)

October 17, 2023

On October 5, 2023, a groundbreaking moment in the field of astronomy occurred when an artificial intelligence (AI) system named Bright Transient Survey Bot (BTSbot) autonomously detected, identified, and classified its first supernova, marking a significant milestone in the realm of space exploration.

AI Redefines Supernova Discovery

Traditionally, the process of discovering supernovae has been time-consuming and labor-intensive. It involves the use of robotic telescopes to capture repetitive images of various sections of the night sky. Astronomers then visually inspect these images to identify new sources of light. If a potential supernova is found, follow-up observations are conducted to confirm its classification.

Meet BTSbot: The AI Game-Changer

BTSbot emerged from the laboratories of Northwestern University in the United States, developed by a team of scientists. This AI system was trained using an extensive dataset comprising over 1.4 million images of supernovae and celestial objects, drawn from nearly 16,000 sources.

The Unveiling of BTSbot’s Supernova Discovery

The momentous event occurred when BTSbot identified a new supernova, aptly named SN2023tyk. The AI system spotted this celestial phenomenon in data collected by the Zwicky Transient Facility (ZTF), a robotic camera stationed in California that systematically scans the northern sky every two days.

BTSbot seamlessly initiated the process by requesting the potential supernova’s spectrum from Palomar Observatory. Another robotic telescope, the Spectral Energy Distribution Machine (SEDM), conducted an exhaustive observation to acquire the necessary spectrum. The data was then transmitted to SNIascore, a tool created by Caltech astronomer Christoffer Fremling, which determined the supernova’s type.

AI’s Pivotal Role in Astronomy

The discovery of a supernova by BTSbot holds immense significance in the field of astronomy for several reasons:

Revolutionizing Supernova Discovery: AI has showcased its potential to revolutionize the way astronomers detect and study supernovae. It enables the rapid and efficient scanning of extensive data from robotic telescopes, reducing the risk of false positives.
Enhancing Supernova Exploration: With AI’s assistance, astronomers can potentially discover a greater number of supernovae, including those that are faint or distant. This accelerates our understanding of these cosmic phenomena.
Accelerating Research: By automating the discovery process, AI allows researchers more time to analyze their observations and formulate hypotheses about the origin of cosmic explosions.
