For the first time in 11 years, Mercury, Venus, Mars, Jupiter and Saturn will be visible at the same time in the sky. All five planets will be seen just before dawn at 6.50am ET on Wednesday, January 20. Hold your arm up straight from the moon to the horizon and the five planets should fall along that line.
If you want to see these aligned planets in all their glory, find a place with very little light pollution, wake up an hour before dawn, and whip out that telescope that you never use. You have about a month to see it happen, so take advantage of this rare moment!
