A rare spiral structure was identified within the disk of forming planets.
Recently analyzed lava samples suggest water was present when the planets were just beginning to form.
After examining the geophysical and geochemical characteristics of Earth's core and mantle, researchers now believe there are higher oxygen concentrations than previously thought. This sheds light on Earth's formation 4.56 billion years ago.
A planetary scientist explains that, with some adaptations, life-forms similar to Earth's could live on other planets' environments as well.
The largest of planets may have formed very differently from what we've thought all along.
It is no secret that more experts than you can count have turned their attention to the stars, searching for planets that would support Earth-like life. The recent discovery of Kepler 452b, the most Earth-like exoplanet ever found, has even sparked a great deal of public interest. However, it's still unclear if any discovery could actually support life. Now a pair of researchers are claiming to have identified a new way to ensure a little more certainty in this exciting hunt.
In work that will likely have far-ranging implications for colloids, nanoparticles, and molecules, researchers at University of Chicago were for the first time able to observe particles gathering in a planetary-formation type process.
On March 18, 2011, NASA's MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft finally inserted itself into orbit around Mercury after six and a half years of traveling across our solar system. Now the 11-year-old spacecraft is finally retiring, with plans to end its career by leaving its mark on the planet it observed for so long.
Normally when we see pictures from space, they are in black and white, causing many to think that any world that isn't a planet must have dusty and colorless landscapes in the otherwise brilliant heavens. Now, however, new images from NASA's Dawn spacecraft challenge that notion, showing us that the massive asteroid known as Ceres is far more colorful than initial black-and-white images suggest.
The Moon: it's a heavenly body of changing faces and meaning. It's commonly associated with horror, romance, and above all, mystery. And even answers concerning how it came to be have remained unknown... until now.
Not too long ago, scientists on the hunt for habitable worlds and extraterrestrial life would have said that the best bet is to look for where there is water. However, they now understand that this sole condition really doesn't do much to narrow things down, as the Universe may very well be awash with the stuff.
An analysis of water vapors from comet 67P/Churyumov-Gerasimenko, the quarry of the Rosetta Spacecraft and its history-making Philae lander, has revealed that its water is not at all like Earth's. This revelation casts some serious doubt on one theory of how our oceans formed, and raises many new questions.
NASA's Dawn spacecraft has the protoplanet Ceres in its sight, and soon will have a close encounter with this unusual alien world. Still, before Dawn get's there, it may help to answer some questions such as "what exactly is Ceres?"
Uranus has always been a pretty lonely planet. The seventh planet from the Sun, this "ice giant" made primarily of ice particles, hydrogen, and helium is relatively unique, drifting around our solar system in an unusual elliptical orbit at a stunning 99 degrees axial tilt. Now, however, researchers are saying that the baby-blue planet has an unlikely twin 25,000 light-years away.
Experts have found evidence of ancient pools of water untouched since Earth's earliest years. These primordial oases could provide researchers clues about our planet's earliest forms of life, serving as windows for peering into the dawn of creation.
