On the mornings of January 9, 10 and 11, 2021, you can watch as the waning crescent moon sweeps past a bright star – Antares in the constellation Scorpius – and an even brighter planet, Venus. Look east before the sun comes up. You can’t miss them if your sky is clear.

EarthSky’s lunar calendar shows the moon phase for every day in 2021. Order yours before they’re gone!

Antares is a red star and represents the Scorpion’s Heart. We in the Northern Hemisphere consider it a summer star, because it’s visible on summer evenings. But it’s up before the sun on cold northern winter mornings. Skywatchers in the Southern Hemisphere can see this star even better than we in the north. From there, it make a grand high arc across the sky. For a specific view of Antares, the moon and Venus on these January mornings, from your location on the globe, try Stellarium.

If you contrast the star Antares with the planet Venus, you’ll find that Antares twinkles fiercely, while Venus shines more steadily. But Venus might be twinkling a bit now, too, because it’s getting so low in the sky before the sun comes up. Venus is much closer to the sun on our sky’s dome than it was a few months ago. And it’s not going to get any higher in the predawn sky between now and sometime in February, when it’ll disappear into the sun’s glare.
