The artist conception shows a newly formed star surrounded by a swirling protoplanetary disk of dust and gas. Debris coalesces to create rocky 'planetesimals' that collide and grow to eventually form planets. The results of this study show that small planets form around stars with a wide range of heavy element content suggesting that their existence might be widespread in the galaxy.

Conservation of Angular Momentum

Check out this and other cool science experiments at http://www.stevespanglerscience.com/experiments/ Ice skaters are not only talented on the ice, but they also have a great understanding of physics as the jump, twist and spin. If you've ever seen seen an ice skater start to spin slowly on the tip of their skate and then speed up into an incredible blur of a spin, the secret is pure science. The best part is that you don't have to be on the ice to test out the science behind the spin. Find an office chair that spins easily and a few weights and you're ready to make yourself dizzy sick. But it's all in the name of science.
