First Ever Picture of a Baby Planet!
For the first time ever, astronomers have captured a direct image of a newly forming planet orbiting around a newly forming star. It’s a stunning photograph, not only for the science and what was observed, but what it means for the future of exoplanetary astronomy.

Awesome!!!
This video make me think of something I'm not clear about on solar system formation; When a proto-planetary disc is forming around a star, I understand that matter wants to clump together over time via gravity. But what makes rock actually melt together, rather than just being a lump of loose gravel like a lot of asteroids? Is it just that if the lump gets to be the size of Ceres or bigger, nothing more than the gravity of it's own mass causes enough pressure at the center to "melt" the rock to become one single object? How do you end up with enough heat so that something the size of Earth is ENTIRELY molten beneath a solid crust?
