The cooperation of people and machines pays off. Discover thousands of new galaxies

During the National Astronomy Meeting that ended yesterday, there was an important announcement regarding the so-called ring of galaxies. It turned out that thanks to human-computer cooperation, about 40,000 structures of this type previously unknown to science have been identified.

The project known as Galaxy Zoo. Its creators created a website where willing people could identify galaxies based on data from telescopes. One of the interesting things is stars whose orbits have been perturbed by colliding galaxies and energy emissions from supermassive black holes.

This is obviously a very daunting task, because the classification of individual organisms is based on millions of measurements. As a result, there is a lot of data that a group of people may have trouble sorting out in their lives. But what is artificial intelligence?

The algorithm that took on this task was named zobot And he can do some really cool things. It is about predicting how a person will interpret a particular piece of information or where an error will occur. Machine learning is the cornerstone of these activities. As Mike Walmsley from the University of Manchester explains, Zoobot allows humans and machines to work together to advance astronomy.

40,000 galaxies discovered thanks to new approach

The effects of this collaboration are impressive. About 40,000 ring galaxies have been discovered. This is six times the number of such structures classified so far. The data collected will be especially useful in the context of a better understanding of the evolution of these organisms. It is distorted and destroyed as a result of collision with other galaxies.

Machine learning is great for analyzing huge amounts of data. Identifying galaxies is not the only area where such solutions exist. Space researchers do not intend to limit themselves and want to use artificial intelligence even in the search for extraterrestrial life. Suffice it to say that only a few days ago, the discovery of a specific Martian meteorite was announced on Earth about 10 years ago. Nothing but artificial intelligence helped.
