Scientists alarmed at short-term ozone-eroding gases

Scientists alarmed at short-term ozone-eroding gases

Environmental scientists raised concern Monday at rising levels of gases that attack Earth's protective ozone layer, including manmade chemicals not covered by a key UN treaty. Researchers at Leeds University in northern England said two computer models highlighted the impact of so-called "very short-lived substances" -- VSLS -- that deplete the stratospheric shield. New ozone-destroying...

Triple solar eclipse on Jupiter

Triple solar eclipse on Jupiter

The Hubble space telescope peers hundreds, thousands, millions of light-years into the universe to study novas, quasars and nebulas. But weeks ago, it pulled its focus way in close -- to just light-minutes away -- to view a rare and beautiful spectacle at the planet Jupiter. Three big moons crossed past it at the same...

4.4byr-old Martian meteorite is piece of planet's crust: Study

New research on a unique 4.4 billion-year-old Martian meteorite reveals it to be a piece of planet Mars, the first of its kind to reach Earth, reports the International Business Times. The Brown University study suggests the Martian landscape is made largely of such composite rocks rather than the igneous type. NWA 7034, the meteorite...

It’s turning out to be a stellar year for the future of autonomous driving as Nasa's Ames Research Center and Nissan North America announced they’re teaming up to develop their own self-driving vehicles that can navigate streets on earth and the surface of Mars. The five-year R&D partnership was announced on Thursday, and engineers...

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...
