583 - How do scientists study distant planets and stars?

Scientists use several methods to study distant planets and stars:

1. Telescopes: They look through big lenses or mirrors that help them see faraway objects in space.
2. Spacecraft: They send spacecraft to fly close to planets and stars to take pictures and collect information.
3. Satellites: They put satellites in space that can look at the planets and stars from up high.
4. Radio signals: They use special machines that can hear radio signals coming from space, which can tell them about the planets and stars.
5. Computer simulations: They use computers to create pretend models of the planets and stars to see what they might look like and how they work.

By combining all these methods, scientists can learn a lot about distant planets and stars, even if they're too far away to visit in person.
