LBN 534 (GAL 110-13) and vdB 158 in Andromeda

Copyright Scott Rosen. Website: http://www.astronomersdoitinthedark.com/

Image
Full Resolution Version

LBN 534 (aka GAL 110-13) is a molecular cloud stretching across more than 1 1/2 degrees of sky in the constellation of Andromeda. The cloud is believed to be part of the star forming Lacerta OB1 association and is about 1,400 light years from us. At the southern end of the cloud (bottom in this image) is the blue reflection nebula, vdB 158.

NGC 1499 - The California Nebula in HaOIIIRGB

Copyright Scott Rosen. Website: http://www.astronomersdoitinthedark.com/

Image

Full Resolution Version

The California Nebula, NGC 1499, is a large HII nebula lying in the constellation of Perseus. The nebula is illuminated by the star, Xi Persei (the bright star just below the main nebula). Although most HII nebulae are illuminated by stars that have formed from within the nebula, Xi Persei did not originate from NGC 1499. Rather, Xi Persei is believed to be a star that was ejected from some other grouping and has "collided" with NGC 1499. These types of stars are known as "runaway" stars.

NGC 1499 is located about 1500 light years away from us in the same Orion arm of the Milky Way that contains our Solar System. The nebula itself is about 100 light years long and covers approximately 4 degrees by 1 degree in the sky (about 8 Full Moons by 2 Full Moons). This image has a field of view a little over 9 degrees by 6 degrees and shows some of the faintest outer parts of the nebula as well as some of the surrounding dusty regions.

Summer Triangle and Milky Way by Andre van der Hoeven, on Flickr

In this image we see the Summer Triangle as seen from Austria in the summer of 2015.
The image was taken using a Nikon D810a equipped with a Nikkor 14-24mm lens.

The Summer Triangle is a Northern Hemisphere asterism (stars of similar brightness recognized in a distinctive shape). Unlike many other asterisms, the Summer Triangle is actually an amalgamation of stars from three separate constellations.

Three stars make up the triangle: Deneb, Vega and Altair. Deneb is the farthest away from Earth among these three, and is the brightest star in the constellation Cygnus; it forms the tail of the Swan. Coincidentally, Deneb is also the head of another asterism known as the Northern Cross, which is contained in Cygnus.

Vega is the brightest star of an otherwise dim and small constellation, Lyra (the Harp). Vega is one of the brightest stars in the night sky. (Sirius is the brightest in the night sky, but appears in the winter of the Northern Hemisphere.) About 12,000 years ago, it used to be the North Star due to an effect called precession, where the Earth's north-pointing direction changes due to a wobbling axis. Rounding out the asterism is Altair, which is the brightest star in the constellation Aquilia (the Eagle.) Altair is one of the brightest close stars to Earth.

The term Summer Triangle was popularized by American author H.A. Rey and British astronomer Sir Patrick Moore in the 1950s. The name can be found in constellation guidebooks as far back as 1913. The Austrian astronomer Oswald Thomas described these stars as Grosses Dreieck (Great Triangle) in the late 1920s and Sommerliches Dreieck (Summerly Triangle) in 1934. The asterism was remarked upon by J. J. Littrow, who described it as the "conspicuous triangle" in the text of his atlas (1866), and Bode connected the stars in a map in a book in 1816, although without label. These are the same stars recognized in the Chinese legend of The Weaver Girl and the Cowherd, a story dating back some 2,600 years, celebrated in the Qixi Festival. In the mid- to late-20th century, before INS, GPS and other electronic/mechanical equipment took their places in military aircraft, United States Air Force navigators referred to this asterism as the "Navigator's Triangle".

Near midnight, the Summer Triangle lies virtually overhead at mid-northern latitudes during the summer months, but can also be seen during spring in the early morning to the East. In the autumn the summer triangle is visible in the evening to the West well until November. From the southern hemisphere it appears upside down and low in the sky during the winter months.
