Scientists discover 'Earth-like' planet

Scientists scouring the sky have discovered an 'Earth-like' planet in the habitable zone.

The new planet, dubbed Kepler-186f, was discovered using NASA's Kepler telescope, which was launched in March 2009 to search for Earth-sized planets in our corner of the Milky Way Galaxy.

A habitable zone planet orbits its star at a distance where any water on the planet's surface is likely to stay liquid. Since liquid water is critical to life on Earth, many astronomers believe the search for extraterrestrial life should focus on planets where liquid water occurs.

"Some people call these habitable planets, which of course we have no idea if they are," astronomer Stephen Kane said. "We simply know that they are in the habitable zone, and that is the best place to start looking for habitable planets."

A computer breakdown at the International Space Station may require a spacewalk by astronauts.

Nasa said a back-up computer on the outside of the orbiting lab was not responding to commands.

The main computer, called an MDM or multiplexer-demultiplexer, is working and the six-man crew is in no danger. But the computers control some robotic functions that would be needed for next week's planned visit by a private SpaceX supply ship.

Mission Control will decide shortly as to whether the computer can be repaired or must be replaced.

Dramatic image of powerful cyclone captured by Nasa

A dramatic image of powerful Tropical Cyclone Ita as it hit land in Australia has been captured by a Nasa satellite.

The satellite passed over the cyclone as it hit the Eastern Cape York Peninsula of Queensland. Scientists said the image indicates the eye is 9.2 miles wide.

Warnings remain place with the centre of Ita expected to remain at hurricane strength as it moves in a southerly direction, staying just west of Cairns for another day.

Life on Mars? 'Lights' in Nasa pictures explained

Images captured by Nasa's Mars Curiosity rover have sparked debate among UFO believers, with some suggesting they "could indicate that there is intelligent life below the ground" on the planet.

The pictures, taken on April 3 by the Curiosity rover's right-hand navcam, appear to show a light in the distance, flaring upwards from behind the hillside.

But the theories have been dispelled by imaging expert Doug Ellison from JPL, Nasa's robotic exploration wing. Speaking to NBC News, he blames the glimmer on a "cosmic ray hit" - when high energy particles hit a surface.

Channel 4 to show video of 9/11 attack from space

Video footage of the aftermath of the 9/11 terror attacks in New York which was filmed from space is to be broadcast in full on UK TV for the first time.

The footage, which shows a plume of smoke stretching from the site of the devastated World Trade Centre towers, was filmed from the International Space Station by astronaut Frank Culbertson.

Hours after the attack Mr Culberston discovered his friend Chic Burlingame was one of the pilots killed, when his plane was hijacked by terrorists.

It will be shown next week as part of Channel 4'S 'Live From Space' season, featuring a number of documentaries about astronauts and a two-and-a-half hour live broadcast from the ISS and Mission Control in Huston, Texas on Sunday March 16.

Images from a NASA satellite shows the progress of the huge weather systems which has battered the UK.

The outline of the UK can be seen on the right underneath the blanket of clouds in both images.

Yesterday three swirling weather systems could be seen heading to the UK across the Atlantic.

Curiosity tweets picture of Earth from surface of Mars

The Mars Curiosity Rover has tweeted an image of the twilight sky and Martian horizon which includes Earth as the brightest point of light in the night sky.

Earth sits left of centre in the picture, with moon is just below.

The view was captured about 80 minutes after sunset on the 529th Martian day, or sol, of the rover's work on Mars (31st January 2014). The image has been processed to remove effects of cosmic rays.

A human observer with normal vision, if standing on Mars, could easily see Earth and the moon as two distinct, bright "evening stars."

'Closest' stellar explosion pictured by NASA spacescraft

An exceptionally close stellar explosion discovered on January 21 has become the focus of observatories around and above the globe, including several NASA spacecraft.

The blast, named SN 2014J, occurred in the galaxy 'M82' and lies about 12 million light-years away. This makes it the nearest optical supernova in two decades and potentially the closest type of supernova to occur during the life of currently operating space missions.

NASA photographs 'Hand of God' after star explodes

NASA has captured an impressive image of a cloud of material in space nicknamed the Hand of God.

The space matter was ejected from an exploded star, NASA said, and photographed using X-ray technology.

NASA calls the formation a "stellar corpse", identified as PSR B1509-58, and says it spins around at seven times per second, firing out material as it goes.
