Astronomers find 'tilted' planets even in pristine solar systems
Scientists have long puzzled over why all of the planets in Earth's solar system have slightly slanted orbits around the sun. But a new, Yale-led study suggests this phenomenon may not be so unusual after all. Even in "pristine" solar systems, planets exhibit a bit of a tilt. Astronomers had long assumed that planets with pitchy, angled orbits - orbits that don't align with the spin axis o
