The most massive known star weighs about 200 Suns

R136a1 sits in the Large Magellanic Cloud, a small galaxy next door to ours. It shines several million times brighter than the Sun. A star like that burns through its fuel so fast that it will live only a few million years, against roughly ten billion for the Sun. Its winds strip away so much matter that it was probably even heavier at birth.

The water in your glass is older than the Sun

A large share of Earth's water molecules formed in the interstellar cloud that existed before the Sun was even born, more than 4.6 billion years ago. You are literally drinking a cosmic fossil.

On Mars, sunsets are blue

By day, the Martian sky looks butterscotch because of fine dust hanging in the air. But at dusk, those same grains scatter blue light forward, creating a bluish glow around the Sun. Rovers have photographed these blue sunsets: the exact reverse of what we see on Earth.
