Kepler-186f planet 'could support life'

An Earth-like planet confirmed by Nasa in the habitable zone around the Kelper-186 star has 'potential' to host liquid water - one of the pre-requisites for life as we know it to exist.

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."

Computer breakdown may force space walk

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.
