SPHERE Snaps Stunning Photos Of Budding Solar Systems

What makes a planet different from a star? A star shines generates its own light by fusing hydrogen atoms in its core. The energy escapes the star from its surface as heat and light. Planets are too small burn elements. They may heat up but they don’t shine. Instead, a planet is visible by the…
