Neptune will reach opposition this month on the 14th Sept, when it lies opposite to the Sun in the sky. Lying in the constellation Aquarius, it will be visible for much of the night, reaching its highest point in the sky around midnight local time.

From Manchester, it will be visible between 22:16 and 03:57. It will become accessible around 22:16, when it rises to an altitude of 21° above your south-eastern horizon. It will reach its highest point in the sky at 01:07, 32° above your southern horizon. It will become inaccessible around 03:57 when it sinks below 22° above your south-western horizon

Constellation of the Month: Aquarius (shown 15th September 00:00)


Aquarius constellation is located in the southern hemisphere. It is one of the 12 zodiac constellations. The constellation’s name means “the water-bearer” (or “cup-bearer”) in Latin

Aquarius lies in the region of the sky which is sometimes referred to as the Sea, because it contains a number of other constellations with names associated with water; Pisces (the fish), Eridanus (the river), and Cetus (the whale), among others. Like other zodiac constellations, Aquarius was catalogued by the Greek astronomer Ptolemy in the 2nd century

Aquarius contains the famous supergiant stars Sadalsuud (Beta Aquarii) and Sadalmelik (Alpha Aquarii), and a number of notable deep sky objects: the globular clusters Messier 2 and Messier 72, the asterism Messier 73, the Aquarius Dwarf Galaxy, Atoms for Peace Galaxy (NGC 7252) and two well-known nebulae: the Saturn Nebula and the Helix Nebula. As well as hosting Neptune during it's opposition this month.
