TruthLens AI Summary

This week, the focus turns to the constellation Boötes, a prominent feature in the northern hemisphere's spring night sky. Recognized as one of the 48 constellations cataloged by the ancient astronomer Ptolemy in the 2nd century, Boötes has maintained its status as one of the 88 official constellations acknowledged by the International Astronomical Union today. Traditionally referred to as the herdsman, Boötes is often depicted in various mythologies as a ploughman, guiding the constellation of Ursa Major, also known as the great bear, around the celestial pole. In some narratives, Ursa Major is transformed into an ox and plough, showcasing the rich tapestry of stories associated with this constellation. Additionally, Boötes shares a connection with the nearby constellation Canes Venatici, which represents hunting dogs, further illustrating the interconnectedness of these celestial figures in historical star maps where Boötes is often shown holding the dogs on a leash.

The constellation Boötes is particularly notable for its brightest star, Arcturus, which is classified as a red giant and ranks as the fourth brightest star visible in the night sky. Although Arcturus has a mass comparable to that of the sun, it has expanded to an impressive 25 times its original size and emits approximately 170 times more light than the sun. For stargazers in London, a clear view of Boötes can be observed looking south-east at around 22:00 BST on May 19, with this view remaining largely unchanged throughout the week. Interestingly, Boötes is also visible from the southern hemisphere, where it appears close to the northern horizon, inviting a wider audience to appreciate its celestial beauty and the stories that it holds.

This week, we track down another prominent constellation in the northern hemisphere’s spring night sky: Boötes, the herdsman. Listed as part of the 48 constellations described by Ptolemy in the 2nd century, it is now one of the International Astronomical Union’s 88 official constellations.

Although known as the herdsman, some stories associated with the constellation depict him as more of a ploughman, driving the constellation of Ursa Major, the great bear, around the pole. In these stories, Ursa Major is changed into an oxen and plough.

The nearby constellation of Canes Venatici, the hunting dogs, is also said to be associated with Boötes. On many old star maps, he is depicted as holding these dogs on a leash.

The chart shows the view looking south-east from London at 22.00BST on 19 May, although the view will remain essentially unchanged all week.

The brightest star in Boötes is the red giant star Arcturus, which is the fourth brightest star in the night sky. Although it has about the same mass as our sun, it has swollen to 25 times its size and now pumps out around 170 times more light.

Boötes is also visible from the southern hemisphere, where it will appear quite close to the northern horizon.
