Venus has returned

Over the past 3 months, Venus has swung around the far side of the sun and appears now in our western sky just after sunset. In June it was positioned behind the sun and was impossible to see. Now, it has moved away from the sun so it can be glimpsed in the bright evening twilight.

Look tonight to the west about 8:15 p.m. You should see a steady "star" — Venus — close to the horizon. Look at it again, this time through binoculars. At the lower left edge of the field lies another object, Mercury. By 8:30 at both Mercury and Venus begin to hug the horizon, dimmer Mars pops into view to Mercury's upper left. There you have the first four planets in our solar system: Mercury, Venus, Earth (you are standing on it) and Mars. Directly south glows bright Jupiter, number 5 from the sun.

Such is our view from Earth ...
