AN August 2026

Two weeks later comes a dramatic partial eclipse of the Moon, while the annual Perseid meteor shower enjoys especially favourable conditions, with no moonlight to spoil the show.

Also in this issue, we mark 20 years since Pluto’s demotion and ask what really makes a planet. Should a world’s status be decided by its orbit and gravitational dominance, or by its geology and character as a world? It is a debate that reaches far beyond Pluto itself.

We also look to the Moon’s future and ask whether lunar astronomy can survive the human return. The lunar far side could be astronomy’s greatest refuge from Earth’s radio noise, but as landers, bases, satellites and rocket debris begin to crowd the Moon, astronomers are racing to protect its most precious observing sites.

In the news pages, discover evidence that Mars once hid a vast underground magma system, why the Bullet Cluster still matters in the dark-matter debate, how SETI researchers are updating the rulebook for first contact, and why two newly confirmed planets are lighter than candy floss.

Plus, Colin Stuart explains how stars form, Martin Howe shows how to take astrophotos on holiday with a digital camera, Jamie Gregory-Macdougall tests Acuter’s Solarus 80 and Sky-Watcher’s SolarQuest, Nik Szymanek reviews new AI-assisted noise-reduction software, and our observing section guides you through the August night sky, from Vulpecula’s Dumbbell Nebula to the month’s eclipses, planets, comets and deep-sky highlights.
