1545 - How can astronomical observations be conducted?

Astronomical observations can be conducted in several ways:

1. Telescopes: Using big tubes with lenses or mirrors to see far-away objects like stars, planets, and galaxies.
2. Spacecraft: Sending robots into space to collect data and take pictures of the universe.
3. Satellites: Orbiting the Earth with special machines that look at the universe.
4. Observatories: Special buildings with big telescopes for stargazing.
5. Binoculars: Even small handheld binoculars can be used to see some stars and planets.
6. Camera Traps: Some scientists use cameras to take pictures of the sky for long periods of time.
7. Radar and Radio Waves: Scientists can also use special machines to detect objects in space using radio waves.

These are just a few examples, and scientists often use a combination of these methods to learn more about the universe.
