New pictures of water ice at Mercury’s north pole — the first such optical images ever — could help scientists better understand how water came to planets in the rest of the Solar System, including Earth. The image...

It's been less than a month since NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft slipped into orbit. But it's already provided mission scientists their first look at Mars' tenuous atmosphere. "Everythin...

An Ariane 5 has lifted off from Europe's Spaceport in Kourou, French Guiana and delivered two telecom satellites, Intelsat-30/DLA-1 and Arsat-1, into their planned orbits.

Today: Extravehicular Activity (EVA) 28: Wiseman and Wilmore completed EVA 28 today. Hatch opening was on time at 7:15am CDT and the EVA was completed with a planned Phased Elapsed Time (PET) of 6 hours and 35 minutes. A...

If or when we make contact with extraterrestrials, the effect on our religious sensibilities will be profound, says astronomer David Weintraub   --

An international team of scientists has succeeded in explaining the formation and propagation over astronomical distances of jets of matter emitted by young stars--one of the most fascinating mysteries of modern astronom...

A group of researchers led by Melina Bersten of Kavli IPMU recently presented a model that provides the first characterization of the progenitor for a hydrogen-deficient supernova. Their model predicts that a bright hot ...

Why is the Sun's million-degree corona, or outermost atmosphere, so much hotter than the Sun's surface? This question has baffled astronomers for decades. Today, a team led by Paola Testa of the Harvard-Smithsonian Cente...

Experts will debate whether or not life is likely to exist on planets orbiting red dwarf stars during a live event tonight. Watch it here at Space.com.

NASA's Goddard Space Flight Center: In the Oct. 17, 2014, issue of Science magazine, five papers based on NASA IRIS data highlight different aspects of the energy's journey from the sun's surface to its atmosphere.

Using instruments aboard the Cassini spacecraft to measure the wobbles of Mimas, the closest of Saturn's regular moons, a Cornell University astronomer publishing in Science, Oct. 17, has inferred that this small moon's ...

We told you earlier this year about an astrophotography contest held by Ciel et Espace Photos in France, called the Photo Nightscape Awards. This is the first year of the competition and the winners have now been announc...

A NASA probe has peered into the sun's atmosphere and found 'bombs' of plasma, jets that affect solar wind and nanoflares that rapidly accelerate particles.

Harvard-Smithsonian Center for Astrophysics: Why is the Sun's million-degree corona, or outermost atmosphere, so much hotter than the Sun's surface? This question has baffled astronomers for decades.

There's something strange going on below the surface of Saturn's Death Star-looking moon Mimas, a new study suggests.

Using the NASA/ESA Hubble Space Telescope astronomers have made what may be the most reliable distance measurement yet of an object that existed in the Universe's formative years. The galaxy is one of the faintest, small...

Instruments aboard NASA's Interface Region Imaging Spectrograph (IRIS) spacecraft have delivered imagery of super heated plasma and jets in a hard-to-study region of the Sun's atmosphere.
