Astronomers Unveil Youngest Known Exoplanet Orbiting Nearby Star

Astronomers have discovered a newborn planet, IRAS 04125+2902 b, in the Taurus Molecular Cloud, using the transit method with NASA's TESS satellite. This 3-million-year-old planet is unusually visible due to a warped debris disk, allowing for detailed observations. The planet, with a mass about a third of Jupiter's but a similar diameter, suggests a low density and an inflated atmosphere, potentially evolving into a mini-Neptune or super-Earth. The discovery raises questions about the causes of disk warping in stellar nurseries.
