[Astronomy Answers] [Dictionary] [AnswerBook] [Universe Family Tree] [Science] [Starry Sky] [Planet Positions] [Calculate] [Colophon]

This page shows the starry sky for 50° north latitude at 0 hours sidereal time. It is approximately 0 hours sidereal time at 0 hours local time at the end of September, at 18 hours local time at the end of December, at 12 hours local time at the end of March, and at 6 hours local time at the end of June.

The black disk indicates the sky, in stereographical projection. The circle at the outer edge of the disk is the horizon. The middle of the disk is the zenith. North is up, east to the left, south at the bottom, and west to the right. The white dots are stars of magnitude 3.5 and brighter. The larger the dot, the brighter the star.

The blue lines indicate the official boundaries of the constellations, with the official latin names also in blue.

The white line indicates the celestial equator (declination 0°) from the equatorial coordinate system. The red line indicates the ecliptic (ecliptical latitude 0°) from the ecliptical coordinate system. The ecliptic is the approximate path of the Sun, Moon, and planets. The purple line shows where the Milky Way is.

At 0 hours sidereal time, Orion rises in the east, with the star Betelgeuse to the upper left from the three stars of Orion's belt, and the star Rigel to the lower right. The Big Dipper (part of the official constellation of the Great Bear [Ursa Major]) is low in the North. The "W" of Cassiopeia is almost straight overhead (in the zenith). The Summer Triangle (made up of the star Deneb in the Swan [Cygnus], Vega in the Lyre [Lyra], and Altair in the Eagle [Aquila]) is in the west. The star Formalhaut in the constellation of the Southern Fishes (Piscis Australis) is low in the south. The Milky Way runs from the eastern horizon through the zenith to the western horizon.
