Satellite images captured an unusual blue feature that researchers are still working to explain.

Astronomers have recently spotted something unusual in space: a blue-tinged interstellar comet named 3I/ATLAS that has stood out in telescope and satellite images as it speeds through our solar system.
First detected in July 2025 by the ATLAS survey telescope in Chile, this object is only the third known visitor from outside our star system. Its strange characteristics, including its unexpected blue tint and unusual motion, have prompted scientists to take a closer look and sparked debate about what is driving these features.
