Astronomers discover a new, rapidly formed planet that challenges existing theories on planetary formation.

Astronomers have found a new planet, named IRAS 04125+2902 b or TIDYE-1b, that formed in just 3 million years, half the time it took Earth. Located 520 light-years away, this planet orbits closer to its star than Mercury does to the Sun and has a diameter 11 times larger than Earth's. Its discovery, made by observing dips in the star's brightness, challenges current theories on how quickly planets can form.
