Mars may have lost much of its original atmosphere, but what's left remains quite active, recent findings from NASA's Mars rover Curiosity indicate.
The Small Magellanic Cloud (SMC) is one of the Milky Way's closest galactic neighbors.
Visible as a small, sparkling hook in the dark sky, the beautiful object below snapped by NASA's Hubble Space Telescope is known as J082354.96+280621.6, or J082354.96 for short.
NASA's Hubble Space Telescope has broken its own record in the quest to find the furthest supernova of the type used to measure cosmic distances.
When a current passes between two electrodes - one thinner than the other - it creates a wind in the air between. If enough voltage is applied, the resulting wind can produce a thrust without the help of motors or fuel.
An instrument mounted aboard the International Space Station (ISS) may have detected its first hint of dark matter.
Astronomers from the University of Maryland at College Park (UMCP) and Lowell Observatory have deployed NASA's Swift satellite to explore comet C/2012 S1 (ISON), which may become one of the most dazzling in decades when it rounds the sun later this year.
Our very own Milky Way is likely a spiral galaxy. Indeed, our solar system and Earth reside somewhere near one of its filamentous, swept-back arms.
Astronomers are observing a black hole that woke up from a decades-long slumber to feed on a low-mass object - either a brown dwarf or a giant planet - that strayed too close.
The Universe is a considerably old neighbourhood, weighing in at approximately 13.8 billion years old. Our galaxy, the Milky Way, is also ancient - as some of its stars are more than 13 billion years old.
Messier 77 is a galaxy in the constellation of Cetus, located approximately 45 million light-years away from Earth.
A recently completed analysis of data from NASA's Cassini spacecraft suggests that Saturn's moons and rings can best be described as gently worn vintage goods from around the time of our solar system's birth.
The European Space Agency's (ESA) Herschel observatory has captured a new view of a vast star-forming cloud called W3.
The privately owned SpaceX Dragon fired its engines for the last time Tuesday at 11:42 a.m. EDT - sending it through the Earth’s atmosphere for a spectacular splashdown in the Pacific Ocean at 12:34 p.m.
The bright galaxy pictured below, known as IRAS 23436+5257, was captured by the NASA/ESA Hubble Space Telescope.
University of Colorado Boulder astronomers studying one of the brightest quasars glowing in the universe some 11 billion years ago say "sideline quasars" likely teamed up with it to heat abundant helium gas billions of years ago, preventing small galaxy formation.
An international team of scientists at the Planck observatory has made the closest reading yet of the most ancient story in our universe: the cosmic microwave background (CMB).
35 years after its momentous launch, Voyager 1 appears to have travelled beyond the influence of the Sun and exited the heliosphere.
Astronomers have identified some of the youngest stars ever seen, thanks to the European Space Agency's (ESA) Herschel space observatory.
NASA's Mars Curiosity rover has identified evidence of water-bearing minerals in rocks near where it had previously found clay minerals inside a drilled rock.
