This coming April we have the Lyrid meteor shower, which will peak on the nights 21st / 22nd and 22nd / 23rd. A meteor shower is named after the constellation from where the meteors appear to come from. In this case the constellation of Lyra the Lyre. A meteor shower is formed from the dust trail left by a comet as it travels around the Sun. A comet is essentially a dirt snowball travelling through space. When the Earth passes through these dust streams we see lots of meteors. These dust grains can hit the atmosphere with speeds of anywhere between 20 and 50 miles per second.
