Shooting stars under Spain's skies Tonight is the night of the shooting stars; the phenomenon is caused by the wake created by comets. Specifically, because comets leave wakes of dust and particles as they approach the sun.
The annual Perseids meteor shower will reach its peak on Wednesday 12 August between 11.30-14.00 hours GMT. The best time to view from the UK will be after dark on 12 August. At the maximum there may be up to 80-100 meteors per hour.
The early morning sky above the emirates will be lit with the light of hundreds of falling meteors on Wednesday. The event, generated by the annual passing of a comet, has been attracting many stargazers and astronomers as Dubai Astronomy Group (DAG) has arranged an open to all facility to enjoy the natures firework near Dubai.
Southern sky holds fuzzy delights This week, stargazers can tour one of the richest pieces of celestial real estate: the Milky Way. Viewing the Milky Way with the unaided eye is a marvellous experience. Wispy clouds of stars so tightly compressed that they appear to the eye as a milky band of light are punctuated not only by bright individual stars, but tiny regions that appear as hazy clumps. Aim binoculars toward these fuzz balls and you will walk the same path followed by Charles Messier 250 years ago.
Members of the public will have a unique opportunity to observe an astronomical highlight of 2009 as the Earth passes through the debris of comet 'Swift-Tuttle', according to a Press release issued by The Society of the Sun on Saturday.
The Perseid meteor showers will peak on the nights of Aug. 11 and 12. Bill Weller, president of the Nanaimo Astronomy Society, said those who want to stay up late can get a fantastic view. Weller recommends finding a remote area where it is darker than urban settings, preferably one with a clear horizon. After that, said Weller, do no more than set up a lawn chair and look up.
