Scientists uncover deep ocean current near Antarctica

Scientists have discovered a fast-moving deep ocean current with the volume of 40 Amazon Rivers near Antarctica that will help researchers monitor the impacts of climate change on the world’s oceans. A team of Australian and Japanese scientists, in a study published in Sunday’s issue of the journal Nature Geoscience, found that the current is a key part of a global ocean circulation pattern that helps control the planet’s... [more]

NASA presents first images from solar observatory

Nasa has unveiled the first images from a new satellite designed to predict disruptive solar storms, and scientists say they are already learning new things. Researchers have showed off brightly coloured images and short movie clips of the sun from the Solar Dynamics Observatory in a webcast. The satellite was launched on 11 February. Dean Pesnell, the chief scientist, says it has already disproved at least one theory, but he did not give... [more]

US confident it could intercept an Iranian missile

Mexico set to enter the space race

Mexican politicians approved the creation of a space agency that will seek to bolster research and raise Mexico’s scientific profile. The lower house of Mexico’s Congress voted to support the agency, which was endorsed by the Senate in 2008. The proposal will now go to President Felipe Calderon for final approval. Politicians said in a statement that if approved by Mr Calderon, the agency will have to convoke Mexican and foreign... [more]

Space shuttle Discovery, crew of 7 back on Earth

Shuttle Discovery and its astronauts returned safely to Earth on Tuesday after making a rare flyover of America’s heartland to wrap up their 15-day, 6 million-mile journey to the International Space Station. The touchdown was delayed by rain and fog that dissipated as the sun rose, allowing Mission Control to take advantage of the morning’s second landing opportunity.

Dutch secret service warns against foreign threat

Foreign secret services are trying to gain access to sensitive Dutch information by sending out e-mails containing Trojan horses, the Dutch intelligence service (AIVD) says in its annual report, published on Tuesday.

The Times said it obtained... [more]

Volcano emitting 150-300,000 tonnes of CO2 daily

Iceland’s Eyjafjoell volcano is emitting between 150,000 and 300,000 tonnes of carbon dioxide (CO2) per day, a figure placing it in the same emissions league as a small-to-medium European economy, experts said on Monday. Assuming the composition of gas to be the same as in an earlier eruption on an adjacent volcano, “the CO2 flux of Eyjafjoell would be 150,000 tonnes per day,” Colin Macpherson, an Earth scientist at Britain’s... [more]

Mysterious New Object Discovered in Space

A strange and mysterious new object in space may the brightest and long-lasting “micro-quasar” seen thus far, a miniature version of the brightest objects in the universe. The object suddenly began pumping out radio waves last year in the relatively nearby galaxy M82, some 10 million light-years away. Its discovery was announced Tuesday. “The new object, which appeared in May 2009, has left us scratching our heads —... [more]

Obama sets new course to conquer the final frontier

President Barack Obama set a bold new course for the future of US space travel when he announced plans to send US astronauts into the orbit of Mars within the next three decades.
