Astronomers Unveil Youngest Known Planet, Challenging Formation Theories

Astronomers have discovered one of the youngest planets ever, TIDYE-1b, at just 3 million years old, using NASA's TESS telescope. This discovery challenges existing models of planetary formation, as TIDYE-1b is visible despite being surrounded by a protoplanetary disc, which usually obscures such young planets. The planet's tilted orbit relative to its star and disc offers new insights into early planet formation, suggesting planets can form earlier than previously thought.
