The Hyades Star Cluster – The “Raining Stars”

The famed V-shaped head of the constellation Taurus is dominated by a lovely collection of blue and orange stars of the Hyades star cluster. Often overshadowed by the smaller and more famous Pleiades, the Hyades are visible high in the northern sky this time of year. They’re visible from the southern hemisphere, too, perhaps 20° above the northern horizon just after sunset in South Africa, Australia, and New Zealand.

The Hyades have been known since antiquity. The cluster’s name comes from the Greek legend of the seven Hyads, the daughters of the titan Atlas and Aethra. Atlas was busy because he had seven more daughters by another wife, Pleione. These daughters were called the Pleiades. So by legend, the Pleiades and the Hyades are half-sisters. Unlike the Pleiades star cluster, the stars of the Hyades are not named after the sisters. And the Hyades contains some 20 stars visible to the naked eye; the Pleiades have just six [Read more…] about The Hyades Star Cluster – The “Raining Stars”

The waxing gibbous Moon will pass in front of the bright star Aldebaran, the brightest star in the constellation Taurus, during the evening of January 19-20, 2016. The event will be visible for all of Canada and the continental U.S. as well as northwestern Europe (see map above). During this occultation, Aldebaran will dramatically disappear behind the darkened edge of the Moon. Then it will suddenly reappear nearly an hour later from behind the lit edge. Exact timing is highly dependent on location, but the event begins between 2h and 3h Universal Time on Jan. 20. You can look up the more precise timing for your location at the Lunar-Occultations.com website. The event is easily visible without optical aid, but a pair of binoculars or a small telescope give you a better view [Read more…] about The Moon Occults Aldebaran on January 19-20

Venus and Saturn Meet in the Morning Sky

January 7, 2016 by Brian Ventrudo Filed Under: Solar System

Venus and Saturn move within 1/2 of a degree of each other on the morning of January 9, 2016.
Venus and Saturn move within 1/2 of a degree of each other in the southeastern predawn sky on the morning of January 9, 2016.

Look to the southeastern sky before dawn on January 9 to see Venus and Saturn make a close approach to each other before sunrise. Venus is the brighter of the two, about 60x brighter than Saturn. The two planets make their closest approach at about 4h Universal Time when they are just 1/10 of a degree apart. This timing favors observers in Europe and Africa. As dawn arrives in the Americas and Australia and New Zealand, the planets will be slightly farther apart but still quite striking. Binoculars will give a good view of the two planets, and a telescope at low-to-medium power will give an excellent view of the face of Venus, which is about 77% illuminated, and the rings and brightest moons of Saturn.

The Dark Universe

It’s been too long since I’ve been in a good planetarium, but this past weekend I saw the splendid “Dark Universe” show at the Hayden Planetarium (pictured) in New York. With dazzling graphics, a lapidary script by Timothy Ferris and narration by Neil deGrasse Tyson, the movie summed up in style the most important discoveries in cosmology over the past 100 years. If you’re visiting NYC, skip an afternoon of shopping and go to the Hayden. It’s worth the trip.

When you know where to look and what to look for, any clear night is a good night for stargazing. Yet some nights– and even days– hold extraordinary events worth an extra glance or perhaps a trip around the world with your telescope and camera in tow. As you plan your stargazing (and other aspects of your life) for 2016, here are 12 celestial events to watch for in the new year [Read more…] about The 12 Best Stargazing Events of 2016
