Boiling water may have carved mysterious streaks on Mars, study finds
Those mysterious dark lines that grow and fade on some of the Red Planet’s slopes might not have all been caused by water flowing on the surface, but violently boiling off of it, a new laboratory study finds.The findings, published in the journal Nature Geoscience, reveal the potential pitfalls of judging Martian geology by Earthly standards — and could alter our understanding of water's role in shaping the surface of our rusty, dusty neighbor. Planetary scientists have long been entranced by d..>> view originalTailless Comet C/2014 S3 Could Provide Vital Information About Solar System: Research
Scientists have discovered a new type of comet that is almost tailless. The comet has been named as Manx object, after Manx cats, which are almost tailless. Scientists said that the newly found class of comet may help solve the mystery of as to how the solar system has been formed. In fact, the discovery of new type of comets might even provide clues about the building blocks of earth. Study’s lead author Karen Meech, an astronomer at the University of Hawaii said that most known comets are fr..>> view originalThree newly discovered Earth-sized planets may be prime spot to hunt alien life
CAPE CANAVERAL, Fla. – Astronomers searching for life beyond our solar system may need to look no farther than a little, feeble nearby star. A Belgian-led team reported Monday that it's discovered three Earth-sized planets orbiting an ultra-cool dwarf star less than 40 light-years away. It's the first time planets have been found around this type of star — and it opens up new, rich territory in the search for extraterrestrial life. Because this star is so close and so faint, astronomers can st..>> view originalGlobal Warming Is Starving West Coast Waters of Oxygen

Cold currents from deep valleys wash nutrients between the Channel Islands, fertilizing plants that are eaten by fish. The fish are eaten by dolphins and pelicans and served with fries to diners watching ocean sunsets from Venice Beach. Rockfish populations that crashed off the southern Californian coast in the 1990s have been protected by fishing..>> view originalIntelligent Alien Life Almost Certainly Existed Somewhere Else, Study Says
A long time ago, on a planet far, far away, intelligent life almost certainly existed, new research suggests. In a study published late April in the journal Astrobiology, researchers Adam Frank and Woodruff Sullivan revised the famous Drake equation, formulated by scientist Frank Drake in 1961. This equation sought to answer the question: Does intelligent life currently exist in the universe? But Frank and Sullivan decided to attack the problem by asking a different question: Has intelligent..>> view originalEurope and Russia move their ExoMars mission launch to 2020
In the statement the ESA released, the agency says they've assessed the situation and "concluded that, taking into account the delays in European and Russian industrial activities and deliveries of the scientific payload, a launch in 2020 would be the best solution." The ExoMars project has been difficulties from the start due to the lack of a proper budget. As the BBC noted, the ESA even teamed up with NASA at one time. But like many relationships, that one ended when they found themselves wit..>> view originalA Rare Celestial Crossing: Mercury Will Transit the Sun on May 9
A snapshot of the November 2006 transit of Mercury. The rocky planet appears as a clean-edged disc in the lower hemisphere of the sun. Clusters of sunspots can also be seen near the right and left edges of the sun. Credit: TheBrockenInAGlory Next week, on Monday, May 9, skywatchers on Earth will be able to see Mercury make its way across the surface of the sun. The so-called transit of Mercury occurs only about 13 times every century, and the next one won't take place until 2019. Cred..>> view originalMethane's role in global warming
It’s perhaps the most contentious issue in U.S. climate change policy right now: How can we deal with emissions of methane, a powerful if short-lived greenhouse gas, which has many sources but appears to be leaking into the air in considerable volumes from U.S. oil and gas operations? The Obama administration is expected to release new methane regulations for new sources of emissions soon, and the EPA recently revised upwards, considerably, its estimates of how much methane is leaking into th..>> view originalBribery for services rampant in Mideast, North Africa, research finds
NEW YORK, May 3 (Thomson Reuters Foundation) - Roughly one in three people in the Middle East and North Africa has recently paid bribes to public officials and for services such as medical care and electricity, and most people say corruption is growing, a watchdog group said on Tuesday.Only a fifth of people who paid a bribe reported the incident, and twice as many said they suffered retaliation when they did report corruption, according to Transparency International.Bribery is common in obtai..>> view originalNASA's Destination Station to stop at sites across Triangle
