A Celestial 2 for 1

   Saturday evening May 2nd the waxing gibbous Moon will be within a few degrees from the bluish-white star Spica in the constellation Virgo the Maiden. Both will easily fit in the field of view of binoculars. And while you are looking at this part of the sky direct your view up to the left from Spica to find the reddish star Arcturus in the constellation Bootes the Herdsman. If you continue looking up to the left you will find the 3 stars making the curved handle of the Big Dipper asterism. If you reverse your viewing then you can do as this astronomical mnemonic suggests, “Follow the Arc to Arcturus, then speed to Spica.”

    Also, on May 2nd the outer planets Mars and Saturn will be on opposite sides of the Sun in an arrangement known as heliocentric opposition.


Caution: Objects viewed with an optical aid are further than they appear.
