AN May 2026

Elsewhere in the issue, we travel to the very edge of the Sun’s domain to explore the vast boundary between our Solar System and interstellar space, and the mission that aims to map it. We also examine a puzzling phenomenon on Mars, where landslips appear to defy the Red Planet’s low gravity, and discover how scientists are recreating these events here on Earth to understand what is really happening.

For observers and imagers, this month’s Smartscope feature takes a major step forward, showing how modern image-processing techniques are transforming what can be achieved with compact, automated telescopes. It is a practical guide to getting the very best from your data, whether you are just starting out or refining an established workflow.

We have our comprehensive guide to May’s night skies, with Mark Armstrong and our team of experts highlighting the best targets for the weeks ahead, alongside the latest Moonwatch in collaboration with the British Astronomical Association and a host of deep-sky objects to explore.

In our equipment section, we put the HAC125DX and Syncam 585C through their paces, assessing this fast, compact imaging system and what it can deliver in real-world use. There are also the usual regular columns, features and a selection of stunning images from around the world.
