The solar-sailing spacecraft LightSail 2 has sent a selfie home as it completes its third year in orbit around Earth.
Meteors, also known as shooting stars, are pieces of dust and debris from space that burn up in Earth's atmosphere, where they can create bright streaks across the night sky. When Earth passes through the dusty trail of a comet or asteroid's orbit, the many streaks of light in the sky are known as a meteor shower. Particularly large chunks of material can create an extra-bright fireball streak, but most meteors are still small enough to entirely burn up in Earth's atmosphere. If a meteor makes it to Earth it's known as a meteorite. Before they hit atmosphere the objects are called meteoroids.
A new analysis of a Martian meteorite is challenging current thinking about how terrestrial planets acquired volatile elements early in their formation.
