Analysis and Evaluation

Many years ago, a mathematician named Johannes Kepler created a set of rules explaining planets' movement in our Solar System.

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.

Did you know that what you weigh depends on the strength of gravity? And did you know that the strength on gravity on other planets is not the same as on Earth?

You have likely heard about the Universe expanding. Or that redshift can tell us about the movements of galaxies. Both are difficult ideas to imagine and understand.

Every year, the Earth completes one orbit of the Sun and every year, you have a birthday! And during a year, the Earth rotates 365 times on its axis and we experience 365 sun rises and sun sets.
