The Skies Of Spring
The days are now getting longer as we pass the vernal (spring) equinox and head toward the summer solstice. Near sunset you can see the planet Venus shining brightly. Around the same time the bright star Sirius will be nearly due south. A little higher in the sky, and to the east, is the planet Jupiter, which is very easily spotted in the constellation of Cancer. With a pair of binoculars one can make out tiny points of light on either side of Jupiter that change from night to night. These 4 bright companions are the 4 largest moons of Jupiter, named after Galileo, who first observed them with his telescope, about 400 years ago!
