Google buys Titan Aerospace, maker of atmospheric satellites

NEW YORK, N.Y. - Google has bought Titan Aerospace, a maker of solar-powered drones, saying it could help bring Internet access to remote parts of the world as well as solve other problems. Financial terms were not disclosed. Google Inc. said Monday that atmospheric satellites could also be used in disaster relief and assessing environmental damage.

Mexican Nobel laureate inducted into French Legion of Honor

Mexico City, Apr 11 (EFE).- Mexican scientist Mario Molina, winner of the 1995 Nobel Prize in Chemistry, was decorated with the Knight medal of the Legion of Honor by French President Francois Hollande in recognition of his services to humanity. The induction ceremony took place at Club France in the Mexican capital, where Hollande arrived Thursday for an official visit to the Aztec nation.

Hidden ocean on Saturn's moon bolsters life theory

Saturn's moon Enceladus is home to an ocean of melted water beneath its surface, and could be a source for alien microbes, scientists said Thursday. The first measurements of the subsurface water at the south pole of the small and icy moon were made by the US space agency's Cassini spacecraft, and are described in the journal Science. The body of water is about the size of Lake Superior, the second largest lake on Earth, and has a rocky bottom which could create conditions that allow tiny life forms to thrive.

Did microbes cause mass extinction?

Volcanoes and asteroids are sometimes blamed for wiping out nearly all life on Earth 252 million years ago, but US research Monday suggested a more small-time criminal: microbes. These microbes, known as Methanosarcina, bloomed in the ocean on a massive and sudden scale, spewing methane into the atmosphere and causing dramatic changes in the chemistry of the oceans and the Earth's climate, according to the new theory put forth by scientists at the Massachusetts Institute of Technology and colleagues in China.

Step aside Saturn: Little asteroid has rings too

By Irene Klotz CAPE CANAVERAL, Florida (Reuters) - It is not just Saturn and the giant gas planets of the solar system that bear rings. For the first time, rings have been found around an asteroid, a study published on Wednesday shows. The asteroid, known as Chariklo, is more than 621 million miles (1 billion km) from Earth, circling the sun in an orbit between Saturn and Uranus.

Astronomers find mini-planet in solar system's backyard

By Irene Klotz CAPE CANAVERAL, Florida (Reuters) - Astronomers have found a dwarf planet far beyond the orbit of Pluto and can only guess how it got there. The diminutive world, provisionally called "2012 VP 113" by the international Minor Planet Center, is estimated to be about 280 miles in diameter, less than half the size of a neighboring dwarf planet named Sedna discovered a decade ago.

Astronomers ring in startling asteroid find

Astonished astronomers said Wednesday they had found rings around an asteroid, the smallest object known to have this feature and only the fifth after Jupiter, Saturn, Uranus and Neptune. The twin rings around a rock called Chariklo were spotted in June last year as it passed in front of a star, scrutinised by seven telescopes dotted over a 1,500-kilometre (930-mile) stretch of South America.

Western U experts say meteorites may contain valuable info about solar system

ST. THOMAS, Ont. - University researchers say at least one chunk of a meteorite may have landed in southwestern Ontario this week — and more rocks may also be waiting to be found. Astronomers from Western University are asking people to check their properties for any remnants of the basketball-sized meteor they say likely came down near St. Thomas, Ont. In Canada, landowners who find a meteorite on their property own it — but the researchers say they'd love to have a look at what they call a "Rosetta Stone" of scientific information.

Planet X myth debunked

It was an elusive planet that for 200 years appeared to explain Uranus's wobbly orbit. And there was the sister sun theorized to be near our solar system that caused asteroids to swerve toward Earth. There is just one problem: neither "Planet X" nor "Nemesis" ever existed, researchers now say. Or probably not.

Dinosaur-killing impact acidified oceans

The space rock that smashed into Earth 65 million years ago, famously wiping out the dinosaurs, unleashed acid rain that turned the ocean surface into a witches' brew, researchers said Sunday. Delving into the riddle of Earth's last mass extinction, Japanese scientists said the impact instantly vaporised sulphur-rich rock, creating a vast cloud of sulphur trioxide (SO3) gas. This mixed with water vapour to create sulphuric acid rain, which would have fallen to the planet's surface within days, acidifying the surface levels of the ocean and killing life therein.
