Numerous failed attempts to find Planet 9—a hypothetical gas giant at the edge of our solar system—have led Taiwanese scientists to rethink their strategy.
For years, astronomers have scanned the sky searching for faint sunlight reflecting off Planet 9, but this method has not been successful.
Now, a team of researchers from Taiwan has adopted a different approach: instead of looking for its light, they are searching for its heat.
Beyond Neptune lies the cold and dark Kuiper Belt, where the orbits of several objects appear to cluster in an unusual way.
The team from Taiwan believes they may have found the strongest evidence yet for the existence of Planet 9.
This difference led the researchers to focus on the planet’s heat signature instead of its light.
These two heat sources appeared exactly where Planet 9 is expected to be, with the right brightness and the predicted motion. »
