MESSENGER reveals Mercury's magnetic field secrets
New data from MESSENGER, the spacecraft that orbited Mercury for four years before crashing into the planet a week ago, reveals Mercury's magnetic field is almost four billion years old. The discovery helps ...
Ancient star raises prospects of intelligent life
Can life survive for billions of years longer than the expected timeline on Earth? As scientists discover older and older solar systems, it's likely that before long we'll find an ancient planet in a habitable ...
Fresh evidence for how water reached Earth found in asteroid debris
Water delivery via asteroids or comets is likely taking place in many other planetary systems, just as it happened on Earth, new research strongly suggests.
Astrophysicists offer proof that famous image shows forming planets
A recent and famous image from deep space marks the first time we've seen a forming planetary system, according to a study by University of Toronto astrophysicists.
Astronomers find first evidence of changing conditions on a super Earth
Astronomers have detected wildly changing temperatures on a super Earth – the first time any atmospheric variability has been observed on a rocky planet outside the solar system – and believe it could ...
New exoplanet too big for its stars
The Australian discovery of a strange exoplanet orbiting a small cool star 500 light years away is challenging ideas about how planets form.
Astronomers probe inner region of young star and its planets
Astronomers have probed deeper than before into a planetary system 130 light-years from Earth. The observations mark the first results of a new exoplanet survey called LEECH (LBT Exozodi Exoplanet Common ...
Irradiating formamide with meteorite dust can lead to synthesis of prebiotic compounds
'Dwarf planet' Ceres spawns giant mystery (Update)
First classified a planet, then an asteroid and then a "dwarf planet" with some traits of a moon—the more scientists learn about Ceres, the weirder it becomes.
Complex organic molecules discovered in infant star system
For the first time, astronomers have detected the presence of complex organic molecules, the building blocks of life, in a protoplanetary disk surrounding a young star, suggesting once again that the conditions ...
New group seeks to timeline the Anthropocene—when humans became the dominant force on Earth
Model shows how gas giants could have survived and spun away from their star
Comet dust—planet Mercury's 'invisible paint'
A team of scientists has a new explanation for the planet Mercury's dark, barely reflective surface. In a paper published in Nature Geoscience, the researchers suggest that a steady dusting of carbon from p ...
Rocky planets may orbit many double stars
Luke Skywalker's home in "Star Wars" is the desert planet Tatooine, with twin sunsets because it orbits two stars. So far, only uninhabitable gas-giant planets have been identified circling such binary stars, ...
