NGC1499, California Nebula

Discovered by Edward Barnard in 1885, the California nebula is a large and relatively close nebula in the Orion Arm of our Galaxy. The nebula glows because of the radiation from the intensely hot, class O star, Xi Persei which is the brightest star in this picture. It extends across 100 light years of space.The distance to the California nebula is not known very precisely, although it definitely lies within the Orion Arm and most estimates place the nebula about 1500 light years away. The most accurate distance to Xi Persei from the Hipparcos Catalogue puts the star roughly 1800 light years away, although it could easily be 500 light years nearer or further.

California Nebula

The California Nebula (NGC 1499) is an emission nebula located in the constellation Perseus. It is so named because it appears to resemble the outline of the US State of California on long exposure photographs. It is almost 2.5° long on the sky and, because of its very low surface brightness, it is extremely difficult to observe visually. It can be observed with a Hβ filter (isolates the Hβ line at 486 nm) in a rich-field telescope under dark skies.^[1] It lies at a distance of about 1,000 light years from Earth. Its fluorescence is due to excitation of the Hβ line in the nebula by the nearby prodigiously energetic O7 star, xi Persei (also known as Menkib, seen at center below it in the inset at right).

The Gegenschein Over Chile

Image Credit & Copyright: Yuri Beletsky (Las Campanas Observatory, Carnegie Institution)

Is the night sky darkest in the direction opposite the Sun? No. In fact, a rarely discernable faint glow known as the gegenschein (German for “counter glow”) can be seen 180 degrees around from the Sun in an extremely dark sky. The gegenschein is sunlight back-scattered off small interplanetary dust particles. These dust particles are millimeter sized splinters from asteroids and orbit in the ecliptic plane of the planets. Pictured above from last year is one of the more spectacular pictures of the gegenschein yet taken. Here a deep exposure of an extremely dark sky over Las Campanas Observatory in Chile shows the gegenschein so clearly that even a surrounding glow is visible. Notable background objects include the Andromeda galaxy, the Pleiades star cluster, the California Nebula, the belt of Orion just below the Orion Nebula and inside Barnard’s Loop, and bright stars Sirius and Betelgeuse. The gegenschein is distinguished from zodiacal light near the Sun by the high angle of reflection. During the day, a phenomenon similar to the gegenschein called the glory can be seen in reflecting air or clouds opposite the Sun from an airplane.
