The Ellensburg, WA sky for the week of October 11, 2025

Saturday: “I’m a little teapot, short and stout. The galactic center, I pour it out.” (I’m a Little Teapot, astronomy version, 2025.) Despite its enormous size and importance, the center of our Milky Way galaxy and its giant black hole remain hidden to the naked eye behind thick clouds of gas and dust. By plotting the orbits of stars near the middle of the galaxy, astronomers have determined that the black hole’s mass is equal to about 4.5 million Suns. While you can’t see the actual galactic center, you can gaze in the direction of the center by looking just to the right of the teapot asterism in the constellation Sagittarius. This point is about a half a fist above the south-southwestern horizon at 8:00 p.m., in line with the moon in the sky.

Sunday: It is good to plan ahead so start thinking about the Orionid meteor shower. This shower, which consists of the earth colliding with pieces of the remains of Halley's Comet's tail, peaks on the morning of October 21 but produces meteors from early October until early November. These meteors appear to come from a point in Orion, the hunter. This point is about one fist above the eastern horizon at midnight. You can follow this point throughout the night as it will remain near the prominent reddish star Betelgeuse (pronounced Bet'-el-jews). The Orionid meteors are fast - up to 40 miles per second.

Monday: Saturn is three fists above due southeast at 9:00 p.m.

Tuesday: Jupiter is to the upper right of the waning crescent moon in the southeastern sky at 6:00 a.m. At this same time, Venus is half a fist above the eastern horizon.

Wednesday: Look up in the sky. It’s a bird. It’s a plane. It’s a dolphin. A dolphin? The constellation Delphinus the dolphin is nearly six fists above due south at 8:00 p.m. The constellation’s two brightest stars are called Sualocin and Rotanev, which is Nicolaus Venator spelled backwards. Venator worked at the Palermo Observatory in Italy in the mid nineteenth century. He slipped these names into Giuseppe Piazzi’s star catalog without him noticing. Sort of like when you would sneak cookies into your parent’s shopping cart, hoping they would not notice.

Thursday: Comet Lemmon (C/2025 A6) may be one of the brightest comets of the year. At 6:00 a.m., it is near the star Cor Caroli, about two and a half fists above the northeastern horizon. First, find the star at the bottom of the Big Dipper handle. Cor Caroli is about one fist to the right of that star. Comet Lemmon will be a little above Cor Caroli. Comet Lemmon will be closest to Earth on October 21. Read more about it at https://earthsky.org/space/comet-lemmon-best-comet-of-2025-finder-maps/.

Friday: Rho Cassiopeiae is the most distant star that can be seen with the naked eye by most people. It is about 8,200 light years away. That means that the light that reaches your eyes from that star left over 8,000 years ago, before the beginning of time according to the Byzantine calendar. Rho Cassiopeiae is nearly straight overhead at 11:00 p.m., just above the zigzag line that marks the constellation Cassiopeia.
