If we all woke up one morning to find the Moon missing, most of us probably wouldn’t notice. Those who live near the oceans would find the tides reduced, but not completely absent. While the Moon does ...

Apollo mission lunar samples provided crucial data, initially intended to test existing Moon formation theories (capture, co-formation, fission), but ultimately leading to the development of the Giant ...

Stars move slowly across the sky over very long periods. The closer a star is, the more easily we can see its movement. Stellar parallax is a shift in a star's apparent position due to Earth's orbit.
