A rare astronomical conjunction will brighten the western sky on 26 August, giving observers a fleeting but dramatic sight. The narrow crescent moon will join the reddish light of Mars, both set in the constellation Virgo.

How close will Mars and the moon appear?
At sunset, Mars will hover less than ten degrees above the horizon. The waxing crescent moon, illuminated at only 11%, will shine less than six degrees to its lower left. To measure the distance, observers can use their hand: a clenched fist at arm’s length spans about ten degrees, while three fingers cover roughly five degrees.

Where should stargazers look for the spectacle?
Viewers will need an unobstructed line of sight towards the western horizon. The pairing will last just over an hour before slipping from view. Through 10x50 binoculars, the lunar surface will reveal the ancient lava plain of Mare Crisium, with Mare Fecunditatis visible further below.

Which stars will complete the scene?
Spica, Virgo’s brightest star, will shine to the upper left of the moon. The dimmer star Porrima will sit about three degrees to the upper right of Mars. By the next evening, the moon will drift past Mars and Spica, continuing towards a meeting with Antares in Scorpius on 31 August, just before the first quarter phase.

The event offers a chance for both casual skywatchers and seasoned photographers to enjoy the August skies. Clear views and patience will reward those who look west at the right time.
