Scientists have discovered the youngest known exoplanet, a baby planet named Elias that is less than one million years old and is still forming around its young star.
The planet, Elias 2-24 b, is about the size of Jupiter and is located roughly 450 light-years from Earth. Researchers say the discovery offers a rare opportunity to study the earliest stages of planet formation.
Astronomers detected the planet in a prominent gap in the gas-and-dust disk surrounding its young host star. The gap is believed to have been created as the growing planet gathers material from the disk.
The discovery could help scientists better understand how giant planets such as Jupiter form and evolve. Previous record holders for the youngest known exoplanets were more than five million years old, making Elias 2-24 b significantly younger.
Researchers said studying the newly discovered world could provide valuable clues about the processes that shape planetary systems during their earliest stages.
