Dr Ian 'Astroblog' Musgrave returns with your October 2026 Sky Guide for Australian skies, including Saturn at opposition (October 4), Mars crossing the Beehive Cluster (M44), the Orionid meteor shower, a daylight Lunar X on the 18th, and the occultation of Elnath (Beta Tauri) on October 29–30.

Venus becomes a wire-thin crescent on its way to inferior conjunction on the 24th, Mercury reaches greatest elongation, and T Coronae Borealis still hasn't gone bang.

In the Tangent: could life be hiding in the clouds of Venus? Ian explores the "unknown absorber" in Venus's sulfuric acid clouds, a new peptide candidate, the phosphine debate, and the microbes living in Earth's 'black smokers' (deep ocean vents).
