Today’s Astronomical Events – May 24th, 2015

Draco the Dragon is at its best visibility of the year tonight. From northern Europe and Canada, the constellation never sets below the horizon and is, therefore, known to be circumpolar. In other words, if you could see the stars throughout the entire day, you’d see Draco spin about the pole star like the planets orbiting the Sun.

Draco is home to a fine double star, Nu Draconis, also known as Kuma. If you have a good pair of binoculars or a small telescope, you should be able to split the star into a pair of equally bright, white stars that some call “the eyes of the dragon.” Located about 100 light years away, one of the stars is actually double itself, although its companion is too close to be seen with amateur telescopes.

The view above represents the sky from North America at 1:00am; observers in the United Kingdom will see a similar view but the constellation will be a little higher in the sky. If you can’t stay up that late, try looking for the dragon earlier in the evening. It should be visible once twilight comes to an end, about an hour and half to two hours after sunset.
