World's oldest water estimated

World's oldest water estimated

The world's oldest water, which is locked deep within the Earth's crust, is present at a far greater volume than was thought, scientists report. The liquid, some of which is billions of years old, is found many kilometres beneath the ground. Researchers estimate there is about 11m cubic kilometres (2.5m cu miles) of it -...

Methane 'belches' detected on Mars

Methane 'belches' detected on Mars

Nasa's Curiosity rover has detected methane on Mars - a gas that could hint at past or present life on the planet. The robot sees very low-level amounts constantly in the background, but it also has monitored a number of short-lived spikes that are 10 times higher. Methane on the Red Planet is intriguing because...

Mysterious US spaceplane returns to Earth

Mysterious US spaceplane returns to Earth

A US plane on a top-secret, two-year mission to space has returned to Earth and landed in California. The aircraft, resembling a miniature space shuttle and known as the Orbital Test Vehicle or X-37B, spent 674 days in orbit around the planet. It touched down at Vandenberg Air Force Base on Friday morning. The purpose of...

Bioluminescent trees could light up our streets

Bioluminescent trees could light up our streets

Dutch designer Daan Roosegaarde’s team – who have conceptualised smart, interactive highways and parks that remove smog particles – are turning their attention to bioluminescent jellies and bacteria. By merging their light producing compound with plants, the team envisions illuminating city streets with trees that glow at night according to a report earthwareone.com. The...

Mars Maven mission arrives in orbit

Mars Maven mission arrives in orbit

The US space agency's (Nasa) latest Mars satellite has arrived successfully in orbit above the planet. Hurtling through space for the past 10 months, the Maven craft slammed on the brakes by firing its thrusters. The 33-minute burn removed sufficient speed to allow the satellite to be captured by Mars' gravity. We made it to Mars...

11b by 2100

The world population may grow larger than previously estimated, reaching 11 billion by century's end, according to a UN-led analysis published Thursday. That would mean two billion more people on Earth than expected by 2100, largely due to high birth rates in Africa, said the report in the US journal Science. "The consensus over the past 20 years or so was that world population, which is currently around seven billion, would go up to nine billion and level off or probably...

Supermoon Sunday will be biggest moon of 2014

Supermoon Sunday will be biggest moon of 2014

On Sunday, Aug. 10, we’ll be treated to a special cosmological treat. The year’s biggest and brightest full moon will rise, reports The Washington Post. Technically there’s only one supermoon a year, and this is it. The term refers to the time when the moon, which orbits Earth in a slightly elliptical trajectory, is...

Ants help cool Earth's climate

Ants help cool Earth's climate

Ants may be cooling the Earth by helping trap carbon dioxide from the environment, a new study has claimed. A long-term experiment tracking the ants' effects on soil suggests they cooled Earth's climate as their numbers grew. "Ants are changing the environment," said lead study author Ronald Dorn, from the Arizona State University in...

Nasa aims to land on asteroids

Nasa aims to land on asteroids

Nasa's mission to land on an asteroid could help save the Earth, the space agency has revealed. The mission is expected to test an 'enhanced gravity tractor' that could be used to push away an asteroid on a collision course with Earth. The technique would use a robotic probe to fly alongside a space...

Mini-planet found in solar system's backyard

Mini-planet found in solar system's backyard

Astronomers have found a dwarf planet far beyond the orbit of Pluto and can only guess how it got there. The diminutive world, provisionally called "2012 VP 113" by the international Minor Planet Center, is estimated to be about 280 miles (450 km) in diameter, less than half the size of a neighboring dwarf...
