Last chance to suggest NASA's message to Voyager 1

Last chance to suggest NASA's message to Voyager 1

Technology
It's the final day for internet users to suggest a message for NASA to beam to the Voyager 1 space probe.The craft is currently almost 13 billion miles from Earth - making it the most distant human-made object ever.It was launched on 15 September 1977 and in order for a message to be beamed to it in time for the 40th anniversary of the mission, NASA is closing the date for suggestions on Tuesday.The space agency is seeking suggestions via Twitter, Instagram, and Facebook for a 60-character message to send to the unmanned Voyager 1.At the end of the entry period, the public will be allowed vote on what short message should be sent to the probe.Public polls can be a risky business in the age of the internet, with the public last year opting to name the UK's new polar research ship Boaty McBo...

The British cyber-security researcher, charged in the US with creating and selling malware, has returned to Twitter to thank his supporters.It is the first time Marcus Hutchins has spoken publicly since his arrest earlier this month in Las Vegas.Earlier on Monday the 23-year-old pleaded "not guilty" during a court hearing in Milwaukee, Wisconsin.A trial has been scheduled for October.

Arctic voyage finds global warming impact on ice, animals

Arctic voyage finds global warming impact on ice, animals

Technology
The email arrived in mid-June, seeking to explode any notion that global warming might turn our Arctic expedition into a summer cruise. "The most important piece of clothing to pack is good, sturdy and warm boots. There is going to be snow and ice on the deck of the icebreaker," it read. "Quality boots are key." The Associated Press was joining international researchers on a month-long, 10,000 kilometer (6,200-mile) journey to document the impact of climate change on the forbidding ice and frigid waters of the Far North. But once the ship entered the fabled Northwest Passage between the Atlantic and the Pacific, there would be nowhere to stop for supplies, no port to shelter in and no help for hundreds of miles if things went wrong. A change in the weather might cause the mercury to drop ...
Scientists find 91 volcanoes under Antarctic ice

Scientists find 91 volcanoes under Antarctic ice

Technology
The largest volcanic region on Earth has been found thousands of meters below the surface of the ice sheet covering Antarctica.A survey of the region of the West Antarctic Rift System has revealed 91 new volcanoes hidden within the ice.The new volcanoes are on top of the 47 whose peaks are above the ice and were already known about.The volcanoes range in height from 100m to a towering 3,850m tall.Geologists say the range has similarities to east Africa's volcanic ridge, which was previously thought to have the densest concentration of volcanoes in the world.Image:The survey was suggested by an undergraduate student at the University of EdinburghIt is unclear whether the Antarctic volcanoes are active, but previous studies have suggested that during warmer periods volcanic activity does occ...

Massive Perseid meteor shower thrills stargazers

Technology
Stargazers were given a treat on Saturday night and in the early hours of Sunday as the Perseid meteor shower dazzled the sky.Meteors are small fragments of interplanetary debris and dust that enter the Earth's atmosphere at such a high speed that they usually burn up, producing the shooting stream of light.The Perseid meteor shower, one of the best-known of the meteor showers, is active from mid July until 24 August but its peak was expected to be this weekend, particularly Saturday night and in the pre-dawn hours of Sunday.One of those who stayed up was Twitter user John-GM7PBB who lives on the Isle of Lewis in Scotland.He told Sky News that he had set his camera up at about 11pm on Saturday and was rewarded with two beautiful images of a meteor above the horizon.His window of opportunit...
