Welcome to the Daily Telescope. There is a little too much darkness in this world and not enough light, a little too much pseudoscience and not enough science. We’ll let other publications offer you a daily horoscope. At Ars Technica, we’re going to take a different route, finding inspiration from very real images of a universe that is filled with stars and wonder.<\/p>\n
Good morning. It\u2019s January 16, and today we\u2019re traveling 2,600 light-years outward into space to the Cygnus Wall.<\/p>\n
Although this sounds like some kind of intergalactic barrier, the Cygnus Wall\u2019s nomenclature has a more mundane origin\u2014it looks like a wall and is located in the Cygnus constellation. It is the brightest region of the so-called North American Nebula, which in some photographs looks like the outline of North America.<\/p>\n
The Cygnus Wall, if you use your imagination, somewhat resembles Central America and Mexico. It is a region of vigorous star formation with lots of hydrogen and sulfur, which produce the reddish hues in this image, and oxygen, shown in blue. This feature measures about 20 light-years across, or more than six times the diameter of our Solar System.<\/p>\n
