Analyse Observations

How do we find asteroids?

Galaxies are collections of millions, or billions of stars. The Milky Way is the galaxy in which we live, orbiting around it’s centre in a distant spiral arm.

Have you ever wondered how big a galaxy is? They contain millions to billions of stars but what does that really mean for size?

Reading about sizes in a book is one thing, but what if you could make an observation of a galaxy and then measure its size?

Have you ever wondered how big each of the planets is? Bigger or smaller than the Earth?

The Sun is a constant presence in our life on Earth. It gives us the heat and light we need to survive. But it is not a stable place. The Sun is a ball of hot plasma which is constantly changing.

Asteroids are small, rocky objects that orbit the Sun. Most are located between the orbits of Mars and Jupiter. This area of our Solar System is known as the Asteroid Belt.

Go Observing includes advanced options where you get to decide the exposure time of the observation and the filter the telescope uses.
