Mars and Jupiter presently lie inside a binocular field-of-view, although you’ll have to rise early to catch them mendacity round 20° excessive at about 3am BST. Each planets are hosted by the intense stars of the constellation of Taurus, the Bull, which offer a suitably gorgeous backdrop main as much as and through shut method.

Mars lies west of Jupiter, mendacity round 5° above orange-red Aldebaran (alpha Tauri) on the morning of seven August. Aldebaran, marking the Bull’s proper eye, dominates the acquainted and vivid ‘V’ form define of the Hyades open cluster, although its not a member of the cluster. As likelihood would have it, each Mars and Aldebaran shine at round magnitude +0.9, and with an identical coloration. Jupiter dazzles at magnitude – 2.2, completely dominating the morning scene.

A small telescope offers an awesome view of the conjunction of Mars and Jupiter. Mars and Jupiter lie round 23’ aside on the morning of 14 August. That is the view via a 80mm (~three-inch) telescope at low energy. There’s a second likelihood to see them as shut on the next evening.

Over the course of the subsequent week, Mars’ extra fast easterly movement via Taurus attracts the purple planet ever nearer to Jupiter. The planetary pair lie inside 1.3° of one another between the mornings of twelfth to seventeenth August.

That is the closest that Mars and Jupiter have been since they had been round 13’ aside within the pre-dawn sky on 7 January 2018.
