Learn what astronomy is, what astronomers study, and how this science explains stars, planets, galaxies, and cosmic events.

Learn why different constellations appear throughout the year, how Earth’s motion changes our night sky, and which star patterns you can see in each season.

Learn how the Moon orbits Earth, why its path is not a perfect circle, and how that motion drives phases, eclipses, and tides.

A clear look at the training, simulations, and teamwork that prepare astronauts to fly and operate complex spacecraft safely.

Explore how astronauts learn space medicine, from emergency care and physiology to simulation training and medical decision-making in microgravity.

Learn why light pollution harms astronomy, what it does to telescopes and observatories, and how smarter lighting can help.

Explore how astronauts prepare for space through physical training, simulations, survival drills, and mission-specific practice.

Astronomers study light because it carries information from distant objects, revealing composition, motion, temperature, and age across the universe.

Learn how to use right ascension and declination to locate stars, planets, and deep-sky objects with clarity and confidence.

Discover how radio telescopes reveal invisible cosmic phenomena, from cold gas and pulsars to black holes, and why they’re essential in modern astronomy.
