SpaceTime Series 27 Episode 144*Young Exoplanet Challenges Planet Formation TheoriesAstronomers have discovered an exoplanet, Taade 1b, that is just 3 million years old, challenging our current understanding of the speed at which planets form. This young planet, orbiting its star every seven Earth days, offers a unique glimpse into the early stages of planetary formation. The study, led by Madison Barber from the University of North Carolina, highlights the surprising rapidity of Taade 1b's formation compared to Earth's estimated 10 to 20 million-year formation period. The discovery provides new insights into the differences between our solar system and those hosting close-in giant planets like Taade 1b.*Photon Shape Revealed by New Quantum TheoryA groundbreaking theory has allowed scientists to define the precise shape of a photon for the first time. Reported in Physical Review Letters, this research explores how photons, as particles of light, interact with matter at the quantum level. The study reveals tha
