Based on a new model that draws from research in diverse fields including petrology, geodynamics, volcanology and geochemistry, the findings of Earth scientists from Rice University, Yale University and the University of Toky
Microscopic "timers" have revealed the likely source of galactic radiation that we detect at Earth. Most of the cosmic rays originated relatively recently in the nearby clusters of massive stars, according to new results from
Astronomers have created a virtual Earth-space radio telescope more than 100,000 miles across - a super-high resolution that reveals new details of a quasar and our Milky Way. The researchers were surprised when their Earth-s
There is strong evidence that the Earth is already one degree Celsius hotter than at the start of the 20th century - and the past four years have been the hottest on record. All this is a a foretaste of a hotter, drier and we
Scientists have identified a common ancestral gene that enabled the evolution of advanced life more than a billion years ago, and without which life on our planet would probably still be bacterial slime. The gene, found in al
Why have we not received any call from the aliens out there yet? What if extraterrestrial observers called but nobody on Earth heard? As scientists step up their search for other life in the universe, two astrophysicists from
A team of scientists has accurately detected a structure in the innermost region of a quasar at a distance of more than five billion light-years from Earth. It's the most accurate measure achieved until now of such a small an
Meteorite death in India: Scientists at the US space agency NASA have discounted reports that an Indian bus driver in Tamil Nadu was killed by a meteorite, saying he was likely hit by a land based explosion.
The interior structure of rocky exoplanets orbiting other stars will have interiors very similar to Earth -- a thin outer crust, a thick mantle, and a Mars-sized core, researchers have shown using a computer model.
Researchers have discovered two new fossil fish species that could swing the jaws open extra wide, like a parachute, from the Cretaceous Period, about 92 million years ago, when dinosaurs roamed Earth.
The US space agency NASA on Tuesday said its new rocket for deep space mission, the Space Launch System (SLS), will carry 13 small satellites along with an uncrewed Orion spacecraft during its first flight in 2018.
Activities like growing plants in space can help astronauts reduce stress, suggests NASA's Behavioural Health and Performance team after pictures of the solitary orange zinnia astronaut Scott Kelly tweeted last week caught th
Astronomers from the California Institute of Technology claim to have find an evidence of a new giant planet that has a mass about 10 times that of Earth and can bring the tally of planets in our solar system back to nine.
