All new satellites built for the U.S. Air Force must be compatible with an experimental ground system that was designed primarily for research missions and is viewed as a steppingstone to a common ground architecture for...

This is not as odd a question as it sounds, and by next week I reckon a good lot of you will be pondering it. Why? Well the 30th September sees the opening of The Martian in Australia, director Ridley Scott's latest offe...

Orbital ATK will be the sole provider of solid-rocket boosters for United Launch Alliance's Atlas 5 and next-generation Vulcan rockets starting around 2019, the companies announced Sept. 22. SpaceNews.com

This weekend's rare supermoon total lunar eclipse offers a mix of risk and scientific opportunity for NASA's Lunar Reconnaissance Orbiter, which has been studying Earth's nearest neighbor up close since 2009.

The Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft arrived in orbit around the Red Planet on Sept. 21, 2014, 10 months after blasting off from Florida's Cape Canaveral Air Force Station.

The winning images from the Insight Astronomy Photographer of the Year competition were announced last week, and the list is an awe-inspiring collection of celestial awesomeness.

The request for information is one of the first steps to commercialize some of the service's satellite operations and transfer others to a new common ground system. SpaceNews.com

The Sunday evening eclipse is the last in a "tetrad" -- a term for four total lunar eclipses happening at six-month intervals -- that has been stunning skywatchers across the United States for the past 18 months,

Self-described "Hubble hugger" John Grunsfeld is at the tiller of NASA's $5 billion-a-year Science Mission Directorate at a time when the agency is celebrating great mission successes, recovering from great planning fail...

Three orbiting X-ray space telescopes have detected an increased rate of X-ray flares from the usually quiet giant black hole at the center of our Milky Way galaxy after new long-term monitoring. Scientists are trying to...

The most luminous galaxies in the universe likely formed slowly via gradual accretion of gas, rather than rapidly via mergers with other galaxies, new research suggests.

This Sunday night moon observers have the chance to see a lunar triple treat, weather permitting. Not only is it a Harvest Full Moon, but also a so-called supermoon and total lunar eclipse.

Extremely luminous early galaxies - such as those simulated here in infrared light - established the structure of galactic clusters observed today by sub-millimeter wavelength telescopes.

ESA's Rosetta spacecraft has provided evidence for a daily water-ice cycle on and near the surface of comets....

Observations by the European Space Agency's Rosetta spacecraft show that surface ice on Comet 67P/Churyumov-Gerasimenko, which Rosetta has been orbiting since August 2014, appears and disappears on a daily cycle tied to ...

This new image of the rose-coloured star forming region Messier 17 was captured by the Wide Field Imager on the MPG/ESO 2.2-metre telescope at ESO's La Silla Observatory in Chile....

The brightest galaxies in our universe are fuelled by what their gravity sucks in, not through explosive mergers of star systems as scientists previously argued, researchers said Wednesday.
