Stars in the Milky Way tend to revolve around the center of the galaxy, bobbing slightly above and below the galactic plane as if in a perpetual cosmic merry-go-round. But sometimes a star gets catapulted across the sky by a close gravitational interaction with another star.  One of the best-known “runaway stars” lies in the constellation Auriga, the Charioteer. Known as AE Aurigae, this blazing star is passing by chance through a cold cloud of interstellar gas. The result is ‘accidental’ emission nebula cataloged as IC 405, but more commonly called the Flaming Star Nebula [Read more…] about The Flaming Star Nebula

Venus, the Hyades, and the Pleiades at Sunset

by Brian Ventrudo Filed Under: Deep Sky, Solar System

Venus-Pleiades-2

The brilliant planet Venus is just over 2° from the Pleiades star cluster, while the V-shaped Hyades star cluster, which makes up much of the constellation Taurus, is to the left of Venus in this image. The constellation Orion is at extreme left. This image taken after sunset over the Ottawa River on a pleasant spring night on April 12, 2015.

Shining at magnitude -4.1 for most of the month, Venus is easy to find high above the western horizon as the Sun goes down. It outshines every object in the sky except for the Sun and Moon. The planet moves a little higher each night until early June.
