Astronomers found an alien world with glowing water atmosphere

Science
Aug. 2 (UPI) -- Scientists have discovered evidence of a stratosphere surrounding a large exoplanet located 900 light-years from Earth.A team of astronomers from the University of Exeter and the University of Maryland discovered glowing water molecules while surveying Hubble's observations of WASP-121b's atmosphere."When it comes to distant exoplanets, which we can't see in the same detail as other planets here in our own solar system, we have to rely on proxy techniques to reveal their structure," Drake Deming, a professor of astronomy at Maryland, said in a news release. "The stratosphere of WASP-121b so hot it can make water vapor glow, which is the basis for our analysis."Water molecules interact with certain wavelengths of light in predictable ways. At cooler temperatures, water molec...
Unexpected life found at bottom of High Arctic lakes

Unexpected life found at bottom of High Arctic lakes

Science
Aug. 1 (UPI) -- In the shallow, frigid waters of Nunavut's Ward Hunt Lake, something mysterious lingers at the lake floor. It's fuzzy, it's bright orange - and it's alive.For more than 50 years, scientists from around the world have traveled to Ward Hunt Lake, the northernmost lake in the Canadian Arctic, to study the region or launch expeditions to the North Pole.Until recently, the prevailing notion was that come wintertime, when night casts a long shadow over the island, the waters would freeze up, and the microbial creatures of the deep that inhabit the lake bottom would all but disappear. But surprisingly, a recent study by researchers at Université Laval, Quebec City found just the opposite.Rather, Ward Hunt Lake is no longer freezing up entirely in the polar night, and as a result,
Dinosaur-era plant found growing in Wisconsin lakes

Dinosaur-era plant found growing in Wisconsin lakes

Science
July 31 (UPI) -- Scientists have found a surprise algae species growing in Wisconsin lakes, a species most thought was existent from the Americas.Lychnothamnus barbatus is a tall algae species. It has previously been found in Europe and Australasia. Cretaceous-era fossils unearthed in Australia offer the only evidence of the species in the Americas.Having disappeared from the scientific record, most assumed it had died out with the dinosaurs. But now, researchers have found the unique algae species living in the Midwest."This means mainly that we don't know as much about what's out there as we could," Richard McCourt, a professor of botany at Drexel University, said in a news release. "Lychnothamnus barbatus' survival isn't, per se, ecologically earth-shaking, but it changes our view of wh...
Organic compounds found by Saturn moon mission

Organic compounds found by Saturn moon mission

Technology
Scientists have urged caution after finding organic compounds around Saturn's moon Enceladus.Enceladus was discovered by the British astronomer William Herschel in 1789 using what was then the largest telescope in the world, measuring 1.2m across.Almost 230 years later, the Cassini spacecraft conducted another fly-past of its southern pole, travelling through one of the mysterious cryovolcanic plumes which had been discovered to be erupting from the moon.Cassini sampled the water-rich plumes, suspected to originate from a vast liquid ocean beneath the surface of Enceladus, and discovered organic compounds - molecules which contain carbon and are essential to all known life.These compounds, including the molecule methanol, have now been detected in a much more massive quantity than previous...
More oil found in the Barents Sea

More oil found in the Barents Sea

Business
July 3 (UPI) -- Norwegian oil company Statoil said Monday it was anticipating more potential near its promising Johan Castberg field after finding oil in a frontier area.The Norwegian Petroleum Directorate, the nation's energy regulator, confirmed the presence of oil in a well drilled about 14 miles southwest of the Johan Castberg field in the Barents Sea. The discovery was made in a wildcat well, one drilled in an area not previously known to hold hydrocarbons."We are particularly pleased to have proven resources in a type of play that has not been explored before," Jez Averty, senior vice president for regional exploration, said in a statement. "This opens interesting opportunities."The NPD put the preliminary size of the discovery, dubbed Kayak, at between 25 million and 50 million barr...
