      Some constellations are really hard to see at night, it makes you wonder what the people who first named them were thinking! Some of this difficulty is because in cities it’s never really that dark due to too many lights around, so the best way to spot them is to get out into the country. This is what the bear, called Ursa Major (larger bear in Latin), looks like:

      Orion is a fairly easy one because it has three bright stars lined up very nicely (his belt) and three more nearby (his sword). It looks like this:

      You won’t always be able to see these constellations though, just like the Sun isn’t always up, neither are particular stars and constellations. For constellations their visibility at night changes throughout the year because the Earth is moving around the Sun, so at night we’re looking at different parts of the sky.

      Did you know that where I am, in Chile, the constellation of Orion is upside-down compared to what you see?? I still find that very weird after living here for a year! I think you have much better constellations in the Northern hemisphere… The only ones I know from the Southern hemisphere are upside-down Orion, one of the ‘dippers’, and the Southern Cross (the main one).

      The Southern Cross is even on the logo for my institute, ESO!
