A scientific team led by University of Louisville doctoral student Karen Collins has discovered a hot Saturn-like planet (KELT-6b) in another solar system 700 light-years away.
NASA's Hubble Space Telescope will have two opportunities in the next few years to hunt for Earth-sized planets around the red dwarf Proxima Centauri.
Although nearly a thousand exoplanets have been detected indirectly — most using the radial velocity or transit methods — and many more candidates await confirmation, only a dozen exoplanets have been directly imaged.
Water-rock reaction may provide enough hydrogen 'food' to sustain life in the ocean's crust or on Mars.
A new series of images from Gemini Observatory shows Comet C/2012 S1 (ISON) racing toward an uncomfortably close rendezvous with the Sun. In late November the comet could present a stunning sight in the twilight sky and remain easily visible, or even brilliant, into early December of this year.
Despite satellite images that illustrate vast networks of channels, past Mars rover missions have shown limited evidence for flowing water on Mars.
Researchers from Northeastern University are among the many scientists helping NASA use the weightlessness of space to design stronger materials here on Earth.
Researchers at the University of Southampton have taken a significant step in a project to unravel the secrets of the structure of our Universe.
Astronomers using NASA's Swift X-ray Telescope have observed a spinning neutron star suddenly slowing down, yielding clues they can use to understand these extremely dense objects.
The Mighty Eagle, NASA's robotic prototype lander managed out of the space agency's Marshall Space Flight Center, recently completed a test series to monitor its systems functionality after coming out of winter storage.
The beautiful, glittering swirl picture belowed is named, rather un-poetically, J125013.50+073441.5.
NASA astronaut Karen Nyberg, Russian Federal Space Agency cosmonaut Fyodor Yurchikhin and European Space Agency (ESA) astronaut Luca Parmitano joined their Expedition 36 crewmates when the hatches between their Soyuz TMA-09M spacecraft and the International Space Station opened at 12:14 a.m. EDT Wednesday.
Computer simulations of galaxies growing over billions of years have revealed a likely scenario for how they feed: a cosmic version of swirly straws.
NASA and a Texas company are exploring the possibility of using a "3D printer" on deep space missions in a way where the "D" would stand for dining.
On May 31, 2013, asteroid 1998 QE2 will sail serenely past Earth, getting no closer than about 3.6 million miles (5.8 million kilometers), or about 15 times the distance between Earth and the moon.
How much light has been emitted by all galaxies since the cosmos began? After all, almost every photon (particle of light) from ultraviolet to far infrared wavelengths ever radiated by all galaxies that ever existed throughout cosmic history is still speeding through the Universe today.
Magnetars – the dense remains of dead stars that erupt sporadically with bursts of high-energy radiation - are some of the most extreme objects known in the Universe.
Researchers at the Universities of Leeds and Chicago have uncovered an important mechanism behind the generation of astrophysical magnetic fields such as that of the Sun.
The Ring Nebula's distinctive shape makes it a popular illustration for astronomy books. But new observations by NASA's Hubble Space Telescope of the glowing gas shroud around an old, dying, sun-like star reveal a new twist.
The ESA (European Space Agency) has inaugurated a new hub that will strengthen Europe’s contribution to the global hunt for asteroids and other hazardous natural objects that may strike Earth.
