Astronomers have spotted the "Godzilla" of all Earths, a huge rocky planet orbiting a star 560 light years away that is changing scientists' understanding of the origins of the universe.
A Russian Proton rocket carrying a European-built satellite fell back to Earth on Friday shortly after liftoff in the latest accident to hit the country's once-proud space industry.
Europe on Thursday launched the first in a constellation of hi-tech satellites designed to monitor Earth for climate change and environmental damage and help disaster relief operations.
When stars explode, it's a messy business. But the massive blasts are also useful, seeding the universe with such key elements as calcium, iron and titanium.
Something wiped out nearly all life on Earth more than 250 million years ago, and whatever unleashed this mass die-off acted much faster than previously thought.
More than 1,000 candidates -- from 200,000 hopefuls -- have been chosen to train for a private Mars colonisation mission to be partly funded by a reality-TV show following their training and subsequent steps, organisers said Thursday.
India's Mars spacecraft suffered a brief engine failure Monday as scientists tried to move it into a higher orbit around Earth, but controllers denied any setback to the ambitious low-cost mission.
A science satellite dubbed the "Ferrari of space" for its sleek, finned looks will shortly run out of fuel and fall to Earth after a successful mission, the European Space Agency (ESA) says.
Earth was cooling until the end of the 19th century and a hundred years later, the planet's surface was on average warmer than at any time in the previous 1,400 years.
Scientists said Sunday they had discovered an unexpectedly large and active community of single-cell organisms living on the Pacific sea floor at the deepest site on Earth.
