The last-quarter Moon will pass through the Hyades star cluster this weekend, on September 4-5, and for observers in eastern North America and western Europe, the Moon will pass in front of the adjacent bright star Aldebaran, the brightest star in the constellation Taurus. During this occultation, the star will disappear behind the lit edge of the Moon, then reappear nearly an hour later, rather dramatically, from behind the dark edge, apparently reemerging out of nowhere. If you’re not in the right place this month, the video above shows Aldebaran as it emerged from behind a waning crescent Moon during an occultation last month [Read more…] about Waning Moon Occults the Star Aldebaran Share This:
The Delta Aquarid meteor shower peaks this year around July 28. This annual event favors observers in the southern hemisphere and southerly latitudes in the northern hemisphere, though all observers can see some of these slow-moving meteors. The meteors of the Delta Aquariids appear to radiate from a point near the star Skat (δ Aquarii) in the constellation Aquarius. The shower peaks around July 27-30, but unlike most meteor showers, the Delta Aquarids lack a sharp peak so meteors are visible from mid-July through early August. The maximum hourly rate can reach 15-20 meteors in a dark sky. Because of their angle of entry into the atmosphere, the Delta Aquariids tend to leave long lingering trails which sets them apart from most other meteors.
