A Clear Voice for Science
It is lucky the moon and planet Venus rank as the second- and third-brightest celestial bodies after the sun. Otherwise, we would have little chance of catching either object in the glow of morning twilight tomorrow (Thursday morning, November 4).
The moon will be the easier of the two worlds to see. Given a clear sky and an unobstructed eastern horizon, people everywhere around the word should be able to spot the thin waning crescent moon an hour or more before sunrise.
Everywhere around the world, Venus rises after the moon. Although Venus rises some 40 to 45 minutes before the sun from most places worldwide, far northern latitudes suffer a disadvantage because Venus stays so close to the horizon. The tropical and southern temperate latitudes see Venus higher in the sky. At our mid-northern latitudes, Venus may be high enough in the sky to see 30 or so minutes before sunup. It will be a challenge, though, and we may need binoculars to do it.
Each month, the moon is said to be reborn at new moon – or when the moon passes from the morning to the evening sky. The moon will turn new by around the start of the weekend. Therefore, the old moon will be seen in the east before sunrise on Thursday – and possibly Friday – and in a few days after that, the young moon will first appear in the western evening dusk on Sunday or Monday.
