SAGITTARIUS

Overview

Sagittarius lies in the summer southern sky, overlapping the densest part of the Milky Way. Because the center of our galaxy lies in this direction, the region is rich with nebulae and star clusters. Its main stars form the well-known Teapot asterism.

The brightest star is Kaus Australis (epsilon, mag 1.85), marking the bottom of the Teapot. Sagittarius is the 15th largest constellation by area.

The center of our Milky Way (Sagittarius A*) lies in this direction, roughly 26,000 light-years away. The supermassive black hole imaged by the Event Horizon Telescope in 2022 was captured looking right through this constellation.

How to Find It

On summer evenings (June through September), look east of Antares in Scorpius for the Teapot shape. It transits around 9 PM in early August. From mid-northern latitudes it stays rather low, so an unobstructed southern horizon helps.

Under dark skies, the Milky Way appears to rise like steam from the Teapot's spout — a remarkable sight. The Teapot's spout, lid, and handle form a distinctive pattern that is easy to recognize once spotted.

Mythology and Culture

In Greek mythology, Sagittarius represents the wise centaur Chiron drawing his bow at Scorpius. Raised by Apollo and Artemis, Chiron was the noblest centaur — master of medicine, music, and martial arts. He mentored heroes including Heracles, Achilles, and Jason.

When one of Heracles' poisoned arrows accidentally struck Chiron, the immortal centaur suffered incurable agony and chose to surrender his immortality to Prometheus. Zeus honored Chiron's virtue by placing him among the stars.

In Babylonian records, the figure appears as "Pabilsag" (the divine archer) over 5,000 years ago, making it one of the oldest zodiac constellations. In Chinese astronomy, the Teapot stars form part of "Dou" (the Dipper/Ladle), known as the Southern Dipper of six stars.

Star Trivia

Kaus Australis (ε Sgr) — About 143 light-years away. A B-type giant at magnitude 1.85, marking the Teapot's base. The name comes from Arabic meaning "southern [part of the] bow." Luminosity ~375× solar.

Nunki (σ Sgr) — Roughly 228 light-years distant. A B-type subgiant at magnitude 2.05 forming the Teapot's handle. Its name comes from Sumerian, making it one of the oldest star names still in use.

Sagittarius A* (Sgr A*) — The supermassive black hole at the Milky Way's center, with ~4 million solar masses. In 2022, the EHT released an image of its "shadow," making worldwide headlines.

Nebula Treasure Trove — The Lagoon Nebula (M8), Trifid Nebula (M20), and Omega Nebula (M17) are all here — famous deep-sky objects for astrophotographers. M8 is visible with binoculars, and a telescope can keep you busy for hours in this region alone.

In Gravity Weaver

Sagittarius is the seventh constellation, with 5 stages. Starting from Nunki, stages progress through Kaus Borealis, Albaldah, Kaus Australis, and Alnasl.

The signature gimmick returns from Scorpius: the Gravity Stream. Across five stages, the current's direction and its relationship to each goal keep shifting.

Deliberately balance riding the current for fast clears with using Gravity Wells to break free of headwinds. Five stages is a long run — losing Solar Shards early makes the later stages unforgiving.
