This evening will be an excellent opportunity to discuss the upcoming Total Solar Eclipse on Monday, April 8th.  We will discuss the best places in the area to view the eclipse and how to view it safely.  Eclipse glasses will be available.

The Moon will be in a waxing gibbous phase, so we will have a beautiful Moon to go with the planets for this session.  We will be looking for many features along the terminator, the line between shadow and light. In these areas, mountains and craters really stand out.

Venus, Mars, Mercury and Saturn will all again be below the horizon, leaving Jupiter, Uranus and Neptune as the planets to view for this session.  All four of the Galilean moons of Jupiter will be visible.

The “Celestial Six-Pack” of winter constellations consisting of Auriga, Canis Major, Canis Minor, Taurus, Orion and Gemini are in great position and will be with us for the next couple of months. They are marked by the stars Sirius, Procyon, Pollux, Caster and Capella as well as Betelgeuse, Rigel and Aldebaran.  Leo, with it’s bright star Regulus is also up in the east. 

We will look at the Pleiades or M45 in Taurus, M36, M37 and M38 in Auriga, M42 the Great Orion Nebula in Orion, M44 the Beehive Cluster in Cancer, and M35 in Gemini.   M31, the Andromeda Galaxy, our nearest neighbor and the Double Cluster will also be possible targets.

Come spend the evening viewing the cosmos with your family, residents and non-residents are welcome!  Students, who are accompanied by their parents, are especially welcome!  Please take note that the dome is not heated or cooled, so pay attention to the weather and dress in a manner that is appropriate for the evening temperature conditions.  If it is raining or cloudy, a planetarium program will be presented instead.
