Headline: Unlocking Cosmic Secrets: The Power of Collaboration in Galaxy ClassificationIn the vast expanse of the night sky, countless galaxies whirl and dance, each with its own unique story to tell. But with billions of these celestial wonders, astronomers face an overwhelming task in deciphering their secrets. That's where citizen astronomers and artificial intelligence (AI) step in, forming a powerful alliance that's transforming our understanding of these cosmic behemoths.

Citizen astronomers and AI discover 30,000 ring galaxies

Citizen Science and AI: A Cosmic Collaboration

Citizen science projects like "GALAXY CRUISE" have revolutionized astronomy by engaging thousands of volunteers to classify galaxies. Armed with nothing more than their computers and a keen eye, these citizen astronomers have played a pivotal role in sifting through vast databases, providing astronomers with invaluable data.

Meanwhile, AI has emerged as a formidable tool for astronomers. Trained on labeled data provided by humans, AI algorithms can now classify galaxies with remarkable accuracy and speed, freeing astronomers from the time-consuming task of manual classification.

A Breakthrough Discovery

Combining the power of citizen scientists and AI, a team of researchers led by Rhythm Shimakawa from Waseda University embarked on a groundbreaking study using data from the Subaru Telescope. Using an AI trained on 20,000 human-classified galaxies, they classified a staggering 700,000 galaxies.

Their findings were astounding: the team discovered approximately 400,000 spiral galaxies and 30,000 ring galaxies. This vast sample of ring galaxies, which account for just 5% of all galaxies, is now large enough for meaningful statistical analysis.

What the Galaxies Reveal

Statistical analysis of the ring galaxies revealed that they display characteristics intermediate between spiral and elliptical galaxies. This finding aligns with the predictions of supercomputer simulations, suggesting that ring galaxies may be the result of mergers or other interactions between galaxies.

Expert Tips for Aspiring Galaxy Classifiers

  • Join a citizen science project: GALAXY CRUISE is just one of many projects that allow you to contribute to astronomy research.
  • Use reliable resources: familiarize yourself with the classifications used by astronomers.
  • Seek guidance: Don't hesitate to ask questions or join online forums for citizen astronomers.


The collaboration between citizen astronomers and AI is a testament to the power of human ingenuity and technology. By combining our strengths, we are unlocking the secrets of the cosmos, one galaxy at a time. I encourage you to join this exciting journey, whether as a volunteer, researcher, or simply an avid stargazer. Together, let's continue to explore the wonders of our universe.
