China’s new AI tool maps 27 million cosmic objects to spot stars, galaxies, quasars

SMRTR summary

A groundbreaking AI tool developed by Chinese astronomers has just mapped 27 million cosmic objects, revolutionizing how we see the universe. This neural network, trained to recognize subtle differences between stars, galaxies, and quasars, combines visual and spectral data to achieve unprecedented accuracy.

"This MNN successfully leverages both morphological and SED information to enable efficient and robust classification," the researchers note, highlighting the AI's dual-input approach.

The model's prowess was evident when it correctly identified 99.7% of stars in the Gaia mission dataset and an equal percentage of galaxies and quasars in the GAMA survey. It even spotted and corrected misclassifications in existing catalogs.

As astronomy enters an era of data deluge, with billions of celestial objects to be observed in coming years, this AI assistant arrives just in time. While not replacing traditional methods, it dramatically expands our ability to process photometric data, potentially uncovering rare cosmic phenomena and deepening our understanding of universal evolution.
