Ash cloud from Iceland's spewing volcano halted air traffic across a wide swath of Europe on Thursday.
A plume of volcanic ash rises into the atmosphere from a crater under about 656 feet of ice at the Eyjafjallajokull glacier in Iceland on April 14. After the volcano's second eruption in less than a month, northern Europe turned into a no-fly zone on Thursday, stranding hundreds of thousands of passengers due to the huge amounts of ash.
The West could help solve Africa's energy dilemma by offering the right incentives for its nations to build green energy projects rather than coal plants.
A spreading plume of ash from an erupting Iceland volcano shut all British airports and effected air travel across northern Europe. The precautions reflect protocols developed after volcanic ash almost caused two disastrous crashes in 1982.
The American landscape is becoming less American as plants from Europe and Asia invade open spaces, crowding out native species and lessening the nation's biological diversity.
Former Alaskan governor and 2008 vice presidential candidate Sarah Palin gives her husband, Todd, a thumbs up as she begins to address a crowd at a stop of the Tea Party Express on Boston Common in Boston, Wednesday.
Australian arrested two Chinese sailors over the grounding of the Shen Neng 1 coal carrier on the Great Barrier Reef, and Australian investigators are looking into the extent of the damage when the ship was grounded while taking an illegal shortcut through the protected ecosystem.
Scientists have found a hydrothermal vent community three miles beneath the sea near the Cayman Islands. Other vents have led to the discovery of new and exotic creatures.
This hydrothermal vent emits black smoke. Hydrothermal vents are fissures in the earth's surface, often found in volcanically active areas. Undersea vents support unique and diverse ecosystems. The base of the food chain in submarine undersea vents is chemosynthetic bacteria fed by chemicals dissolved in the vent fluid.
The Chinese coal freighter Shen Neng 1 that grounded on the Great Barrier Reef has been moved to safety. But the incident has made the public aware that freighters routinely take illegal shortcuts through the reef, and politicians are calling for steeper fines and legal action to protect it.
