Nasa have announced official confirmation of the first Earth-like planet orbiting in the habitable zone of another star.
Thousands of stargazers have captured the total lunar eclipse, or 'Blood Moon,' across the Americas early this morning.
An ocean of water that could support life lies under the surface of Saturn's tiny moon Enceladus, scientists have confirmed.
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.
Nasa research scientist Tom Barclay has said that the hopes of the Kelper team have been answered with the discovery of Kepler-186f.
The discovery of the Earth-like planet orbiting star Kepler has demonstrated the existence of planets that could potentially hold life.
Lewis Vaughan Jones reports:
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 lunar eclipse has unfolded for over three hours across American timezones, after the moon began moving into the earth's shadow.
The moon fully eclipsed between the colours of orange, red and brown glows.
The below image was taken while the moon glowed red in Buenos Aires:
Tuesday's eclipse will be the first of four total lunar eclipses that will take place between 2014 to 2015.
Two significant events will take place simultaneously as Mars reaches its closest point to Earth while the Moon will be totally eclipsed, causing the whole moon to turn red.
The expected lunar eclipse can be seen in North America and on the YouTube channel below from 07:00am UK time.
The live image stream will be hosted by Slooh Observatory Director Paul Cox and Slooh astronomer Bob Berman, who will be reporting live from Prescott Observatory in Prescott, Arizona.
The International Space Station has been photographed soaring over England by cameraman Peter Rossiter.
Stargazers in the UK have been glued to the skies this winter to see the ISS orbiting above.
With clear skies the best times to see the man-made object should be between 9.04pm and 10.40pm.
A competition has been launched asking people to name astronaut Tim Peake's mission to the International Space Station.
Peake, who is set to become the first Briton to visit the ISS, took time out from his training to talk to school groups and hear some of their suggestions for the mission's name.
Minister for Universities and Science David Willetts said: "The naming competition is just one of many opportunities for young people to get involved in a mission that will shape the future of Britain’s space programme and inspire generations.”
Peake said: “The ISS is a cutting edge research laboratory that is pushing the boundaries of what is scientifically, technically and humanly possibly. My 6 month stay onboard mankind's outpost in space is going to be both challenging and incredibly exciting."
The winning entrant will see their suggested name become the mission's official title and they will receive a signed mission logo.
