In 2019, the Event Horizon Telescope revealed the first image of a black hole, at the heart of galaxy M87, 55 million light-years away. To get that sharpness, radio telescopes on several continents observed together, forming a virtual instrument as wide as our planet. That black hole weighs about 6.5 billion Suns.
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.
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.
