How Does a Solar System Form?

The James Webb Space Telescope, due to launch in 2018, will push aside the curtain to watch the process of stellar birth. In largely opaque regions called nebulae, dust and gas swirl together to create stars and proto-planetary systems. The Hubble Space Telescope has peered into these regions, but the JWST, optimized to see infrared light that penetrates the dust, will give astronomers a better view of these baby solar systems than ever before.
