Find the Teapot, and look toward the galaxy’s center

With the moon waning now, it’s time to go out in the country to witness the glorious Milky Way. Want to locate the direction to the galaxy’s center? This post points the way.

Modern stargazers have a hard time seeing a Centaur with a bow and arrow in the constellation Sagittarius. But the Teapot – in the western half of Sagittarius – is easy to make out. The Teapot is an asterism, not a constellation, but a recognizable pattern of stars. It’s best viewed during the evening hours from about July to September. Find the Teapot, and you’ll be looking toward the center of our Milky Way galaxy.

How can you find it? One thing to note is that – unlike some named star patterns – the Teapot actually looks like its name. It really resembles a Teapot:

Raul Cortes in Monterrey, Mexico, caught the moon and the planets Saturn and Mars on August 22, 2018. He also caught the legendary Teapot pattern in the constellation Sagittarius, and the stars Shaula and Lesath in the Tail of Scorpius the Scorpion.

From the Northern Hemisphere, look southward in July and August evenings to see these stars. From the Southern Hemisphere, look generally northward, higher in the sky and turn this chart upside down. Chart via AstroBob.

The center of the galaxy is located between the Tail of Scorpius and the Teapot of Sagittarius. From the Northern Hemisphere, look southward in July and August evenings to see these stars. From the Southern Hemisphere, look generally northward, higher in the sky and turn this chart upside down. Chart via Astro Bob.

Because the sun passes in front of Sagittarius from about December 18 to January 20, the Teapot isn’t visible then. However, about a half year later – on July 1 – the Teapot climbs to its highest point for the night around midnight (1 a.m. daylight saving time), when it appears due south as seen from the Northern Hemisphere or due north as seen from the Southern Hemisphere.

As seen from our mid-northern latitudes, the Teapot rises in the southeast about three hours before it climbs to its highest point, then sets in the southwest about three hours afterwards.

The Teapot returns to the same place in the sky about four minutes earlier with each passing day, or two hours earlier with each passing month. On August 1, the Teapot climbs to its highest point around 10 p.m. (11 p.m. daylight saving time). On September 1, it climbs highest around 8 p.m. (9 p.m. daylight saving time). On October 1, it’s highest around 6 p.m. (7 p.m. daylight saving time).

Another noteworthy point lies in this direction in space, the point at which the sun shines on the December solstice, around December 21 each year.

From the Northern Hemisphere, look southward in July and August to find the Teapot in Sagittarius. Notice 2 points: galactic center and winter solstice.  From the Southern Hemisphere, turn this chart upside down.

From the Northern Hemisphere, look southward in July and August to find the Teapot in Sagittarius. From the Southern Hemisphere, look generally northward, and high in the sky, and turn this chart upside down.

Bottom line: The Teapot asterism in the constellation Sagittarius is easy to spot in a dark sky. When you look in that direction, you’re looking toward the center of our Milky Way galaxy.
