AI detects “supernova” on its own for the first time in the world Both taking photos – confirming – publishing without any humans involved at all Scientists spend much of each day trying to spot the death of stars known as ‘supernovae.’ Seeing them helps researchers understand more about stellar evolution. Astronomers will look for points of light that never existed in the sky. It then asked various observatories to confirm and compile various data to classify them. They then publish (publish) their findings. But with the advent of “artificial intelligence,” or AI, scientists hope it will cut down on the time required. So they developed a new tool called ‘Bright Transient Survey Bot’ (BTSbot), an AI that learns from more than 1.4 million images from nearly 16,000 sources to look for one thing: supernovae. And they succeeded in the real world on October 3rd. The astronomical observation center ‘Zwicky Transient Facility’ (ZTF) is also an automated telescope. A photo of one area of the sky was captured and stored in the data. Just two days later, on October 5, BTSbot was able to detect the newly formed spot of light. and named it ‘SN2023tyk’.But instead of just informing astronomers, Artificial intelligence has made contact with another automated telescope called SEDM (Spectral Energy Distribution Machine) at Palomar Observatory. to collect spectral data for classification and to confirm it from other sources. Once the supernova was all confirmed, BTSbot published its findings on the International Astronomical Union’s website on October 7, without humans. The discovery indicates that it was a type 1 supernova about 760 million light years from Earth. “This is the first time that a suite of robots and AI algorithms have observed The supernova was then identified and communicated with another telescope to confirm the supernova’s discovery,” said Adam Miller, AI project leader at Northwestern University. In the case of a type LA supernova, it is an explosion from a white dwarf that pulls in the material of its companion star. When a large amount of matter flows in, The white dwarf will burn up and explode, destroying them both. And it creates a light that may be brighter than all the surrounding stars combined. Yet it is extremely difficult for humans to observe. “We have achieved the world’s first fully automatic detection, identification and classification of a supernova. ” added Nabeel Rehemtulla, a scientist on the AI development team. “This provides more data to study large supernovae. It will help us better understand the life cycle of stars and the origins of the elements that supernovae produce, such as carbon, iron and gold.” These artificial intelligences will allow scientists to spend more time on other analysis. and make astronomy work more efficient and let the AI do its job.” We don’t really do anything,” Rehemtulla said. “We go to sleep at night and in the morning we see BTSbot and these other AIs doing their jobs continuously.” This system It was developed by researchers from many institutions including: Northwestern University It collaborates with astronomers at Caltech, the University of Minnesota, Liverpool John Moores University and Stockholm University.
