Change the common sense of celestial observation or discover unknown celestial bodies on AI October 1st, 6:04
AI = artificial intelligence may change the common sense of astronomical observation.
Research teams such as the University of Tokyo have developed the world's first observation device that quickly finds unknown celestial bodies by photographing the night sky with a special telescope and analyzing the enormous amount of data from AI. Observations will begin in October. It was decided.
Developed by research teams such as the University of Tokyo, this observation system is an astronomical telescope with 84 high-performance video sensors attached to it. It was named.
The observation system changes the direction of the telescope little by little every 6 seconds and takes a video of the entire night sky over a period of 2 hours. AI = artificial intelligence is used to detect slight changes in light and star position shifts. Find out in real time.
Since the amount of video shot overnight is 30 terabytes, or 10,000 movies, it is possible to analyze such a large amount of data in a short time only by using AI. about it.
According to the research team, it is the world's first effort to comprehensively observe the night sky with videos, so using this observation system, the stars suddenly shine brightly, about 1000 `` supernovas '' annually,
The goal is to find about 100 unknown asteroids annually.
Assistant Professor Shigeyuki Sakamu of the University of Tokyo, who is the team leader, says, “I want to capture the small changes in the universe that humankind has never seen, and make new discoveries.”
Already discovered supernova
We don't know when and where new celestial bodies such as supernovae that start to shine brightly after a big explosion of stars, undiscovered comets, and asteroids will appear.
In order to find new celestial bodies efficiently, it is necessary to observe as wide a range as possible and check for changes in the light of the stars, but as the range is expanded, the number of stars increases. It will be difficult.
The newly developed “Tomo Egozen” will shoot 100 million stars in a video every night. It is AI = artificial intelligence that analyzes the enormous amount of data.
The AI of “Tomo Gozen” means that it can analyze images in just 10 minutes and detect celestial bodies that move specially or appear suddenly.
There are a lot of data that can be confused with astronomical phenomena, such as atmospheric fluctuations and noise in electrical signals, but the research team has learned this data in advance by AI so that it can be removed automatically.
The results are sent to the laboratory in Mitaka City, Tokyo, in real time, and displayed in the form of scores in the order in which they are likely to be new objects.
In addition to discovering one supernova that appeared in the direction of Leo in experimental observations so far, it is also possible to capture the appearance of the Japanese X-ray observation satellite “Hitomi” that has become uncontrollable. Has succeeded.
“We can make a lot of data valuable by using AI. By applying big data methods to astronomy, we can surpass the human imagination. I hope I can make a discovery. "
