This week, the planet Mars will pass through the Beehive star cluster, also known as Messier 44, in the constellation Cancer. The cluster, visible in the night sky, has been recognized since ancient times and was historically referred to by its Latin name Praesepe, meaning "manger" or "crib," due to its hazy appearance.

Despite being one of the brightest star clusters, the Beehive can be challenging to locate because Cancer lacks prominent stars to serve as reference points. This week, Mars acts as a helpful guide, appearing as a moderately bright red object near the cluster. Observers in dark locations should be able to spot a faint, misty patch close to Mars, marking the position of the Beehive cluster.

The optimal viewing time is during the early morning hours; for example, at 2 a.m. British Summer Time on October 13th, the cluster and Mars are visible looking east from London. Observers are advised to allow at least 20 minutes for their eyes to adjust to the darkness before attempting to observe the cluster, and to avoid looking at bright screens during this period, as the light can impair night vision.

Using binoculars can significantly enhance the viewing experience by resolving the Beehive’s indistinct haze into numerous individual stars. However, light pollution may hinder visibility, making it more difficult to see the cluster clearly in urban or brightly lit areas.
