Venus spent the last nine months as the Evening Star, but it's now faintly visible to the unaided eye just before sunrise — and possibly also just before sunset on the same day. For telescopic observers, this is the most exciting possible time to view Venus during broad daylight. But when doing this, be super-careful not to look at the Sun and blind yourself!
The Red Planet travels through one of the biggest and brightest star clusters in the sky from May 21st to the 24th. As a warm-up, stargazers watched Mars pass a hair's-breadth north of 5th-magnitude Eta Cancri on the evening of May 19th in easternmost America and the morning of the 20th in western Europe.
Comet C/2007 W1 (Boattini) has reached 5th magnitude as of early June. It's now visible only from the Southern Hemisphere. When it reappears for northerners in July, will it be naked-eye?
