Mysterious 'ball' on Mars: Where did it come from?NASA says that a remarkably spherical rock spotted by the Curiosity Mars rover is a sign that the Red Planet harbored water in its ancient past.
Some of Earth's water is actually older than the sun, say scientistsUp to half of the water in Earth's oceans is older than the sun and the rest of the solar system, finds new research that suggests that water might be more plentiful in young solar systems than previously thought.
- Which came first, Earth's water or the sun?
New research suggests that a significant amount of water found on Earth today likely formed outside the solar system before the birth of our sun.
Scientists unveil plans for DIY 'invisibility cloak'Researchers at the University of Rochester in New York have unveiled instructions to create a cloaking device capable of rendering a 3-dimensional object invisible.
- Earthquake swarm: Why 600 mini-quakes hit Mammoth Lakes, Calif.
Earthquake swarm: Hundreds of small earthquakes over two days near Mammoth Lakes do not appear to be a precursor to a big quake or a volcanic eruption.
Rosetta orbiter has a date with history on Nov. 12The European Space Agency announced Friday that the Rosetta orbiter will attempt to land on comet 67P/Churyumov-Gerasimenko on Nov. 12. A successful touchdown would be the first time any spacecraft landed on a comet.
Curiosity takes its first bite out of Mars' mountainNASA scientists hope that samples taken from the base of Mt. Sharp will provide clues about Mars' environment during the mountain's formation.
Astronomers detect water molecules on Neptune-sized exoplanetExoplanet HAT-P-11b is the smallest exoplanet in which astronomers have been able to detect water molecules.
Precision toolmaking arrived independently in Eurasia and Africa, say scientistsArtifacts uncovered at a 325,000-year-old archeological site in Armenia suggest that, contrary to what scientists previously thought, Homo sapiens were not the first to develop precision tools.
Earth's water is pretty old. Does that make alien life more likely?Scientists have determined that Earth's water could not have formed after the birth of our solar system, and instead was inherited as ice from interstellar space.
Despite broken solar panel, Soyuz docks safely with space stationOnce the US/Russia crew assuaged concerns about a stuck solar array, the astronauts aboard Soyuz experienced a smooth ride to the International Space Station Thursday night.
Ancient Africans weren't only ones to fashion advanced stone toolsScientists examined about 3,000 stone artifacts at an Armenian archaeological site and discovered that early hominids were using the same sophisticated toolmaking method used by early Homo sapiens in Africa.
Alaska earthquake: Powerful temblor rattles AnchorageAlaska's earthquake had a preliminary magnitude of 6.2. It lingered for at least a minute in some areas, and was felt across much of the state.
Our water is older than our sun, say scientistsScientists have traced the origins of water in our solar system to before the formation of the sun, indicating that other solar systems may contain a similar abundance of the life-friendly substance.
NASA's MAVEN orbiter snaps its first photos of MarsJust eight hours after entering the Red Planet's orbit, NASA's MAVEN orbiter has sent back it's first images of Mars's upper atmosphere.
Mysterious spherical fossils could be oldest known animalsA series of bizarre spherical fossils unearthed in China and dating back 600 million years could be the remains of some of the earliest animals.
- Scientists discover water vapor on distant, Neptune-esque alien planet
Astronomers say they have spotted water vapor in the atmosphere of a Neptune-sized planet some 124 light years away, making it the smallest planet beyond our solar system to show signs of water.
India reaches Mars: Why it mattersMore than half of all Mars missions fail, but India's Mars Orbiter Mission was not one of them, an extraordinary feat for a mission that began just three years ago.
Clear skies on HAT-P-11b pull back curtain on potentially habitable planetsHAT-P-11b isn't habitable, but it's relatively small and cool and has clear skies. If other, more-promising planets its size have similarly clear skies, they could provide evidence of life.
- Has cosmic inflation theory been deflated?
Researchers have found that the highly publicized BICEP2 findings, which lent support to the theory that the universe rapidly expanded in the first few moments after the Big Bang, might be flawed.
