Over the weekend I had a fantastic view of the stars so with my digital camera I took the above photo using an 8 second time-lapse exposure. Then using Wikipedia I researched who each of those stars were.
What I didnt realise at the time was that I had just taken a picture of four Main sequence stars (the same type of star as our sun), a Red giant,
a Variable star and a Binary star.
It is also in the plough asterism (ursa major constelation) that on the 15th of January 1996, Mr Hubbles telescope looked back billions of years and in taking just 342 separate exposures gave us a snapshot containing over 3000 galaxies out of just two parts in a million of the whole sky.
