🚀 Space Science

• Space science (astronomy) studies everything beyond Earth—planets, stars, galaxies, and the universe itself.

• The universe is about 13.8 billion years old and contains billions of galaxies, each with billions of stars.

• Light from distant stars takes years to reach us—we see the past when we look at the sky!

• Space exploration has given us satellites, GPS, weather forecasting, and dreams of living on other worlds.
