One of the constellations of the zodiac

Sagittarius with Jupiter and Saturn

Sagittarius is a prominent constellation located in the southern sky, best visible during the summer months in the Northern Hemisphere. It is one of the 12 constellations of the zodiac and is traditionally represented as a centaur archer, drawing a bow. Despite this mythological image, the stars of Sagittarius form a much more recognizable pattern known as “The Teapot”, an asterism that resembles a teapot with a handle, spout, and lid. This part of the sky is especially rich in celestial objects, as it lies in the direction of the center of the Milky Way galaxy.

Astronomically, Sagittarius is home to many fascinating deep-sky objects due to its position in a densely packed region of the Milky Way. Some of the most notable include the Lagoon Nebula (M8), Trifid Nebula (M20), Omega Nebula (M17), and the Sagittarius Star Cloud (M24)—all of which are star-forming regions and can be seen with binoculars or a small telescope. Also within Sagittarius lies Sagittarius A*, a powerful radio source that marks the location of the supermassive black hole at the center of our galaxy. This makes the constellation especially important in both amateur astronomy and professional astrophysics.

In mythology, Sagittarius is associated with the centaur Chiron or sometimes Crotus, a skilled archer and companion to the Muses. The constellation has been recognized by many ancient cultures and is often linked to themes of strength, wisdom, and exploration. Today, Sagittarius remains a favorite for stargazers not only because of its mythological significance but also for the wealth of celestial wonders it contains, particularly when viewed from dark-sky locations during summer nights.

Where to Find It

Find the Constellation Sagittarius

To find the constellation Sagittarius in the night sky, look toward the southern sky during summer months in the Northern Hemisphere, especially from June to August, when it is highest after sunset. Begin by locating the bright constellation Scorpius, with its distinctive curved tail and red supergiant star Antares. Just to the left (east) of Scorpius lies Sagittarius. Look for a teapot-shaped pattern of stars, commonly referred to as “The Teapot” asterism, which represents the main part of the constellation. The spout of the teapot points toward the center of the Milky Way galaxy, making this area of the sky rich with star clusters and nebulae. Sagittarius is best viewed from dark locations away from city lights, and a star map or app can help you identify it more easily among the crowded stars of the Milky Way.
