Spot the comet


Stars in our eyes: Will you spot Comet Lulin?
From roughly the 16th of the month, not only will we be able to see Comet Lulin with the naked eye but also within two degrees of it you will find the ringed planet Saturn. This should be a beautiful sight through binoculars, all you need to do is find it. Look for the constellation Ursa Major, often called The Plough, which most people are familiar with, then find the two pointers which show us the way to the Pole star. If you follow the pointers in the opposite direction of Polaris and continue until you come to the first big constellation, this will be Leo, identified by the back-to-front question mark. Look down and slightly to the left for the brightest object in this constellation, which at the moment is Saturn, and just below this will be Comet Lulin. As the days pass so the comet will start moving upwards and to the right.
Comets originate in a vast region of space which borders our solar system called the Oort Cloud. As they swirl around, some smash into each other and like snooker balls on a table get fired off in a different direction and this starts their long cold journey into our solar system. As they near the sun the ice starts to melt and gas and vapour start streaming out through evaporation; this is how the tail forms, which clearly identifies a comet.
Most Comets that enter our solar system get caught by the gravitational pull of the sun and end up making the same journey back into space. Eventually they come back some time in the future, like the most famous of them all; Halley's Comet, which makes this journey every 76 years. But some comets just fly straight through our system and are never seen again. Comet Lulin looks like it may well be one of these comets.
So if we are fortunate to have clear skies at the end of February, try and catch a glimpse of one of mother nature’s most remarkable phenomena.
