Astronomy Picture Of the Day (APOD)
Big Dipper, Deep Sky
23.01.2016
The Big Dipper is an easy to recognize, well-known asterism in northern skies, though many see the Plough or Wagon. Famous bright nebulae of the north can also be found along its familiar lines, highlighted in this carefully composed scene with telescopic insets framed in the wider-field skyview.
International Space Station Transits Saturn
22.01.2016
From low Earth orbit to the outer Solar System, this remarkable video frame composite follows the International Space Station's transit of Saturn. On January 15, the well-timed capture from a site near Dulmen, Germany required telescope and camera to be positioned along the predicted transit centerline, a path only 40 meters wide.
The View Toward M101
21.01.2016
Sweeping through northern skies, Comet Catalina (C/2013 US10) made its closest approach on January 17, passing about 6 light-minutes from our fair planet. Dust and ion tails clearly separated in this Earth-based view, the comet is also posed for a Messier moment, near the line-of-sight to M101, grand spiral galaxy in Ursa Major.
Stars and Globules in the Running Chicken Nebula
20.01.2016
The eggs from this gigantic chicken may form into stars. The featured emission nebula, shown in scientifically assigned colors, is cataloged as IC 2944 but known as the Running Chicken Nebula for the shape of its greater appearance. Seen toward the top of the image are small, dark molecular clouds rich in obscuring cosmic dust.
A Dark Sand Dune on Mars
19.01.2016
What is that dark sand dune doing on Mars? NASA's robotic rover Curiosity has been studying it to find out, making this the first-ever up-close investigation of an active sane dune on another world.
Proxima Centauri: The Closest Star
18.01.2016
Does the closest star to our Sun have planets? No one is sure -- but you can now follow frequent updates of a new search that is taking place during the first few months of this year. The closest star, Proxima Centauri, is the nearest member of the Alpha Centauri star system.
The Galactic Center in Infrared
17.01.2016
The center of our Galaxy is a busy place. In visible light, much of the Galactic Center is obscured by opaque dust. In infrared light, however, dust glows more and obscures less, allowing nearly one million stars to be recorded in the featured photograph.
The View Toward M106
16.01.2016
A big, bright, beautiful spiral, Messier 106 is at the center of this galaxy filled cosmic vista. The two degree wide telescopic field of view looks toward the well-trained constellation Canes Venatici, near the handle of the Big Dipper.
Wright Mons in Color
15.01.2016
Informally named Wright Mons, a broad mountain about 150 kilometers across and 4 kilometers high with a wide, deep summit depression is featured in this inset image captured during the New Horizons flyby of Pluto in July 2015.
Infrared Portrait of the Large Magellanic Cloud
14.01.2016
Cosmic dust clouds ripple across this infrared portrait of our Milky Way's satellite galaxy, the Large Magellanic Cloud. In fact, the remarkable composite image from the Herschel Space Observatory and the Spitzer Space Telescope show that dust clouds fill this neighboring dwarf galaxy, much like dust along the plane of the Milky Way itself.
