91 Aquarii (Psi1 Aquarii): A Mulitple Star System

Zeta Aquarii, a binary star system in Aquarius, is about 92 light-years away. First identified by William Herschel in 1777, it appears as a single point to the naked eye. Both stars are similar F-type main-sequence stars, orbiting each other every 587 years, exhibiting complexity beneath their apparent simplicity. This post explores the star and illustrates what it looks like in the telescope. Also known as: STF 2909, SAO 146108, HIP 110960, GC 31398, HR 8558, Zet1 Aqr, 55 Aquarii, HD 213052, 55 Aqr

The Helix Nebula: The “Eye of God” Looks Back at You

In late summer and autumn, the constellation Aquarius, known as the Water Bearer, is prominent in the southern skies of the Northern Hemisphere. Among its features is the Helix Nebula, one of the closest planetary nebulae to Earth. It’s also known as NGC 7293, Caldwell 63, Arp 336.

NGC 7009: The Saturn Nebula

The Saturn Nebula, also known as Caldwell 55, is a planetary nebula viewable in the northern night sky in autumn in constellation Aquarius. Even though dim nebulas like NGC 7009 can be challenging to view in suburban backyards because of light pollution, astronomers should not loose heart. This nebula is pretty easy to spot on a moonless night with a smaller telescope. It will appear light-blue or green and as a small smudge in the scope.
