A pawful of stardust
Though our stable Solar System is now thousands of light years from any star-forming action, we humans have understood the basics of how stars are born since at least the days of Immanuel Kant. In 1755, he suggested that clouds of space matter slowly gathered into very dense clumps, eventually becoming heavy enough to form the sun and later the planets. Called the nebular hypothesis, this is still the best-supported model of how planetary systems form, and it appears all across the universe. This image—captured by the James Webb Space Telescope—details the Cat's Paw Nebula, an active stellar nursery over 4,000 light years away.
