Scientists have discovered what appear to be ice-spewing volcanoes on the surface of Pluto Vans Old Skool Pro Marine Bleu Pas Cher , raising questions about how the tiny, distant world has been so geologically active, according to research presented on Monday.
The findings, released at an American Astronomical Society meeting in National Harbor, Maryland, paint a far more complicated picture of Pluto and its moons than scientists imagined.
"The Pluto system is baffling us Vans Old Skool Canvas Burgundy Blanche Pas Cher ," planetary scientist Alan Stern, with the Southwest Research Institute in Boulder, Colorado, told reporters during a webcast news conference.
Stern heads the team working on NASA's New Horizons spacecraft, which made an unprecedented pass by Pluto on July 14.
Pictures and measurements taken during the encounter are still being transmitted back to Earth.
Among 50 reports that New Horizons scientists will present this week is a startling look at two mountains on the surface of Pluto, each measuring more than 100 miles (161 km) in diameter and several miles (km) in height. The tops of the mountains have depressions similar to volcanoes found on Mars and Earth.
"Nothing like this has ever been seen in the outer solar system Vans Old Skool Grise Blanche Pas Cher ," said New Horizons scientist Oliver White, with NASA's Ames Research Center in Moffett Field, California.
Rather than spewing molten rock, volcanoes on Pluto would have released frozen water, and other ices such as nitrogen, ammonia or methane.
White admits the idea of volcanoes on Pluto Vans Old Skool Classic Bleu Blanche Pas Cher , which is about 30 times farther away from the sun than Earth, sounds crazy, "but it's the least crazy thing we can thing of" to explain the mountains.
"Whatever they are, they're definitely weird," White said.
New Horizons also found several deep fractures in Pluto's surface, the largest of which spans more than 200 miles (322 km)in length. The top of the fracture is about 2.5 miles (4 km)higher than the base - more than twice as high as walls of the Grand Canyon.
"The fact that there are so many large faults in this part of Pluto indicates that the crust has experienced a major extension at some point in its history Vans Old Skool Pro Rouge Pas Cher ," White said.
Scientists suspect the decay of naturally occurring radioactive elements in Pluto's core was the heat source for its transformation.
New Horizons is on track for a possible January 2019 pass by another frozen mini world in the Kuiper Belt region of the solar system, which is home to Pluto, its moons and thousands of other icy bodies.
BEIJING, Nov. 25 (Xinhua) -- China's securities regulator has approved five IPO applications, which will raise up to 3.2 billion yuan (about 484 million U.S. dollars) in the A-share market.
Two companies will be listed on the Shanghai Stock Exchange, two on the Shenzhen small and medium enterprise board Vans Old Skool Reissue Blanche Pas Cher , and one on the ChiNext, a NASDAQ-style board, according to the China Securities Regulatory Commission (CSRC).
The firms and their underwriters will confirm dates and publish prospectuses following discussion with the exchanges.
New shares are subject to official approval under the current IPO system, which is gradually moving to a more market-oriented system.
Since suspending IPOs between July and November 2015, China has sought to normalize IPOs to improve financing efficiency and direct more money into the real economy.
LONDON, Nov. 16 (Xinhua) -- UN Secretary General Antonio Guterres on Thursday highlighted China's efforts in combating terrorism Vans SK8 Hi Slim Lerather Blanche Pas Cher , encouraging China to continue its role in international cooperation against terrorism.
"China is dedicated in United Nations to international cooperation against terrorism, I strongly encourage China to go on play that role," Guterres made the remarks in London when answering a question from Xinhua after he gave a lecture on counter-terrorism and human rights at the School of Oriental and African Studies of the University of London.
Guterres stressed the need for much stronger international cooperation in terms of counter-terrorism. He announced in his speech that he intends to convene the first-ever UN summit of heads of counter-terrorism agencies next year to forge new partnerships and build relationships of trust.
The UN chief also underlined the "urgent need" for governments and security agencies to collaborate more effectively in fighting terror.
He called on UN Member States to increase international efforts to address terror financing, and improve information exchange among security services.
"I heard this message loud and clear. During the high-level week of my first General Assembly in September, 152 leaders - 80 percent of all Members of the United Nations - highlighted the need to step up the exchange of information," he said.
Noting that at least 11 Vans Sk8 Hi Reissue Leather Blanche Pas Cher ,000 terrorist attacks occurred in more than 100 countries last year, Guterres warned that terrorism had become "an unprecedented threat to international peace, security and development."
"Terrorism has been unfortunately with us in various forms across ages and continents. But modern terrorism is being waged on an entirely different scale, and notably its geographic span. No country can claim to be immune," he said.
But he pointed out that developing countries suffered the most despite the truth that terror attacks in the west drew more spotlight.
"Although the spotlight tends to focus on terrorism in the west, we should never forget that the vast majority of terrorist attacks take place in developing countries Vans Old Skool Pro Noir Pas Cher ," he said.
Indicating that nearly three-quarters of all deaths caused by terrorism were in just five states, namely Iraq, Afghanistan, Syria, Nigeria and Somalia, Guterres said economic impact of terrorism is also huge.
In 2015 Vans Old Skool Reissue Noir Pas Cher , terrorism costs amounted to 17.3 percent of gross domestic product (GDP) in Iraq and 16.8 percent in Afghanistan. The global economic impact of te.
