A foundation worth building

Astronomy begins with ideas you can understand.

Orbits, angles, light and scale. Connect classroom concepts to the sky, one short lesson at a time.

NSEA includes substantial physics and mathematics. Astronomy facts alone won’t cover the syllabus.

Explore all lessons
A small question. A useful connection.

Move twice as far from a star. How does its observed flux change?

A   It doubles
B   It becomes one quarter
C   It stays the same

Assume the star’s luminosity is unchanged and space is transparent.
