In the night sky: Orion

You’ll examine one of the most famous constellations, Orion, who the Ancient Greeks believed was a huntsman placed among the stars by Zeus himself.

Starting with its famous nebula where new stars and planets are being formed, you’ll take a look at the seven brightest stars that make up this constellation, including the supergiants Rigel and Betelgeuse, using high-quality images from telescopes such as the Hubble Space Telescope.

You’ll find out about exoplanets, planets that orbit other stars just as we orbit the Sun and may hold the secrets to life outside of the solar system. Finally you’ll think about the Milky Way, the galaxy of which our solar system is but one small part, and consider the history of the universe from the Big Bang to the present.
