Look into the western sky this week to see an eye-catching conjunction between Mars and Regulus, the brightest star in the constellation of Leo, the lion. The chart shows the view from London at 2300 BST on 16 June 2025. The pair of celestial objects will be separated by less than a degree, less than twice the apparent diameter of the full moon. This means that as well as being an easy spot with the naked eye, they are close enough to fit into the same field of view when viewed through binoculars.

Summer in the UK and similar northern latitudes is the best time of year to catch sight of the zodiacal constellation Scorpius, the scorpion. The constellation contains the beautiful star Antares. Shining blood-red just above the southern horizon, Antares is a prize well worth tracking down and this week, the moon helps point it out. The chart shows the view looking south from London at 23:00 BST on 9 June.

It’s time to watch for the beautiful cloud formations known as noctilucent clouds. Latin for “night shining”, noctilucent clouds are seasonal and become visible in the northern hemisphere from late spring/early summer. Although unpredictable, when they do appear they will be seen in the western sky about half an hour after the sun sets. As the sky darkens into night, they will shine with an extraordinary electric blue colour.
