This image of a circular depression on the surface of Mars was acquired on Jan. 5, 2015 by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter (MRO). The spacecraft has been orbiting Mars since March 2006 and completed its 40,000th orbit around Mars on Feb. 7, 2015.

The moon passed between Nasa's Deep Space Climate Observatory and the Earth, allowing the satellite to capture this rare image of the moon's far side in full sunlight. We normally don't see this side of the moon. As the moon is tidally locked to the earth and doesn't rotate, we only ever see the one face from the earth. Awesome shot!
The N44 has a smaller bubble structure inside known as N44F. The superbubble structure of N44 itself is shaped by the radiation pressure of a 40-star group located near its center; the stars are blue-white, very luminous, and incredibly powerful. N44F has been shaped in a similar manner; it has a hot, massive central star with an unusually powerful stellar wind that moves at 7 million kilometers per hour.

The “Black Widow” Pulsar is moving through the galaxy at a speed of almost a million kilometers per hour. Its high-energy wind also has a dramatic effect on its companion star, which orbits the pulsar every 9.2 hours. (Credit: NASA/CXC/M.Weiss)...

Endless: This all-sky view of the entire near-infrared sky reveals the distribution of galaxies beyond the Milky Way. The image is derived from the 2MASS Extended Source Catalog, which contains more than 1.5 million galaxies, and the Point Source Catalog, which holds nearly 500 million stars within the Milky Way. The galaxies are color coded for distances obtained by various surveys. The nearest sources are blue, moderately distant sources are green, and red represents the farthest so

The Orion Nebula is in fact part of a much larger nebula that is known as the Orion Molecular Cloud Complex, which extends throughout the constellation of Orion and includes Barnard's Loop, the Horsehead Nebula, M43, M78 and the Flame Nebula. - Astrophotography by Roth Ritter - http://www.darkatmospheres.com/astro/gallery/nebulae/enlarge.php?fileBase=nebulae_10

The Medialuna Nebula, cataloged as NGC 6888, also called Crescent Nebula or Caldwell 27, is an emission nebula in the constellation of the Swan, located 6º southwest of the star Sadr γ Cygni. The image is of the astrophotographer Sara Wager and collected in its web SwagAstro. It is at a distance of the Earth of about 4700 light-years, within our galaxy, the Milky Way.
