What's Up This Week?
 
Hello skywatchers!

This week's sky is all about bright, beautiful targets, from a dazzling evening planet to a glowing full moon that will light up the start of May.

Look out for bright, brilliant Venus shining low in the western sky after sunset, while Jupiter puts on a subtle but fascinating show as it briefly hides one of its largest moons. As the week draws to a close, the sky delivers a seasonal highlight, the full Flower Moon rising at sunset on May 1.

Elsewhere in this issue, we're looking ahead to the 2026 total solar eclipse with a guide to 15 expert-picked viewing spots across Spain, Iceland and Greenland, alongside a striking astrophotography feature revealing the moon as you've rarely seen it. We're also exploring four fascinating 'firsts' you can spot in the night sky. 

Let's take a look at what to watch for the week ahead.
