The Synthesis of "radial velocity"

Discover the radial velocity method, a key technique using the Doppler effect to find distant exoplanets by observing tiny stellar 'wobbles'.

What is escape velocity? Discover the speed needed to break free from a planet's gravity and why it's essential for all space exploration.

Discover angular momentum, the property of a rotating object that keeps it spinning. Learn how it shapes everything from ice skaters to galaxies.

Discover right ascension, the celestial equivalent of longitude. Learn how astronomers use this coordinate to map and locate stars, galaxies, and planets.
