Black Holes

Think about a massive star — far bigger than our Sun — living its life by burning fuel in its core. This burning creates pressure that pushes outward, while gravity pulls inward. As long as these forces balance, the star lives. When the fuel runs out, the outward pressure disappears. Gravity wins.

Kepler-22b

At 2.4 times Earth’s radius, Kepler-22b sits in a curious category between rocky and gaseous worlds. Astronomers call these “super-Earths” or “mini-Neptunes,” planets that may possess thick atmospheres or vast global oceans.

White Dwarf Stars

When stars die, they don’t all go out in a blaze of glory. Some fade away — quietly, beautifully — leaving behind a glowing core that tells the story of…
