Tomorrow morning, our Moon will pass directly in front of Aldebaran , the brightest star in this picture and in entire constellation of Taurus . Aldebaran is visible to the left and below Comet Hale-Bopp in the above photograph , which was taken on April 30th in Tenerife , Spain. This occultation is valuable because disappearance times from different locations can be used to map the height of the lunar terrain at the occultation points. You can help by clicking here , where a site will detail how to tape a familiar cable channel and then take your still-running camcorder outside to tape the occultation of Aldebaran by the Moon. You can then donate your VCR tape to science by mailing it to this address .
