Star Map May 2015Mercury is low in the west-northwest, below and slightly to the right. It remains visible for the first half of May before returning towards the Sun.

Venus is in the west at dusk. Look high over the point of sunset for the brightest thing there. 

Jupiter is now high in the west as soon as night falls. Jupiter outshines all stars we ever see at night, so it will be obvious when you look up at dusk.   

Saturn enters the evening sky this month. It rises May 1 by 9:40 p.m. By May 22, it is up literally all night; it rises at sundown and sets at sunrise. This is because Earth is aligned between the Sun and Saturn on that date. We therefore say that Saturn is at opposition. 

Mars is lost in the glare of the Sun.

A swath of brilliant winter stars sets in the west at dusk. Orion, the Hunter, is still visible in the west as May begins. His two dogs, represented by Sirius and Procyon, are to his left.  Gemini, the Twins, are above Orion. The Big Dipper is above the North Star, with its handle pointing to the right. From that handle, you can ‘arc to Arcturus’ and then ‘speed on to Spica’; those stars are high in the east and in the south, respectively, at dusk. Leo, the Lion, passes almost overhead at dusk.

As Orion and Taurus set, look for Antares, brightest star of Scorpius, the Scorpion, to rise in the southeast. Saturn will be right on the Scorpion’s head, above Antares. At the same time, Vega, brightest star of the Summer Triangle, appears low in the northeast. These stars remind us that summer is on the way.Phases10-9x-3w

In case you missed the news, the main telescope at George Observatory is once again fully operational. Thanks in large part to public support, we were able to get our mirror cleaned and then reinstalled. The newly refurbished mirror was opened to the public last weekend. Come join us on clear Saturday nights at the George!

On most clear Saturday nights at the George Observatory, you can hear me do live star tours on the observation deck with a green laser pointer.  If you’re there, listen for my announcement. I generally do one such tour on short May evenings.

Clear skies!
