Astrophysicists from the universities of Warwick and Cambridge in the UK have found evidence of what was once a water-rich rocky planet outside our solar system, by analysing the atmosphere of white dwarf star GD 61.
The science community has been abuzz with rumours recently that Mars Curiosity rover had found something big on Mars but in a briefing at the fall meeting of the American Geophysical Union, NASA scientists played down the hype.
In a study released last week, scientists attached to Nevada’s Desert Research Institute (DRI) revealed the existence of bacteria in one of Earth’s most alien habitats, 20 metres below a frozen lake in Antarctica.
NASA talked tantalisingly about a discovery made by its Mars Curiosity Rover this week that could "get in the history books" but finding out what exactly that discovery may be will have to wait a few weeks until NASA has checked results.
Australia and South Africa agreed in the Netherlands Friday of sharing the Square Kilometre Array (SKA) telescope, the world's most powerful radio telescope. The SKA telescope is believed to be strong enough to detect extraterrestrial life.
A new estimate of habitable planets orbiting red dwarf stars, considered the most common in our galaxy, indicates there may be "tens of billions" of rocky planets like our Earth in the Milky Way galaxy alone and about 100 in the Sun's neighborhood.
Our sun's sibling HD 162826 is not visible to the unaided eye, but can be seen with low-power binoculars near the bright star Vega in the night sky.
