By Will Dunham WASHINGTON (Reuters) – Observations by the James Webb Space Telescope are giving scientists a fuller understanding about the composition and evolution of Pluto’s moon Charon, the largest moon orbiting any of our solar system’s dwarf planets. Webb for the first time detected carbon dioxide and hydrogen peroxide – both frozen as solids – on the surface of Charon, a spherical body about 750 miles (1,200 km) in diameter, researchers said on Tuesday. […]
by Daniel Lawler Agence France-Presse PARIS, France (AFP) – Strange lumpy terrain on Pluto unlike anything previously observed in the solar system indicates that giant ice volcanoes were active relatively recently on the dwarf planet, scientists said on Tuesday. The observation, which was made by analysing images taken by NASA’s New Horizons spacecraft, suggests that Pluto’s interior was hotter much later than previously thought, according to a new study in the Nature Communications journal. Rather than […]
TAMPA, United States (AFP) — Pluto is covered with surprising dunes made of methane ice, which have formed relatively recently despite the frigid dwarf planet’s very thin atmosphere, international researchers said Thursday. Pluto’s atmosphere has a surface pressure 100,000 times lower than Earth’s, which researchers suspected might be too little to allow tiny grains of solid methane to mobilize and become airborne. Yet mild winds blowing across Pluto’s surface at speeds of some 19-25 miles […]
Reuters — A team of scientists seeking to restore Pluto to planet hood launched a campaign on Tuesday (March 21) to broaden the astronomical classifications which led to its demotion to a “dwarf planet” a decade ago. Six scientists from institutions across the United States argued that Pluto deserves to be a full planet, along with some 110 other bodies in the solar system, including Earth’s moon. In a paper presented at an international planetary […]
Reuters — NASA has brought Pluto into focus for earth dwellers with a stop-motion video of over 100 colour images taken by the agency’s New Horizons spacecraft. The photographs showing the approach to the dwarf planet were released on January 19 and were taken over six weeks in the summer of 2015. The New Horizons spacecraft flew for more than nine years and three billion miles to visit the Pluto system. “The challenge […]
JULY 16 (Reuters) — NASA’s New Horizons science team revealed new images of distant Pluto on Wednesday (July 15), revealing methane gas, and topography complete with mountains and water “in great abundance.” A U.S. spacecraft sailed past the tiny planet Pluto in the distant reaches of the solar system on Tuesday (July 15), capping a journey of 3 billion miles (4.88 billion km) that began nine and a half years ago. The NASA New Horizons […]
(REUTERS) NASA’s New Horizons spacecraft is poised to become the first probe to visit distant Pluto, capping a reconnaissance of the solar system that began more than 50 years ago. NASA said images they are recieving from New Horizons, taken on July 9 from 3.3 million miles (5.4 million kilometers) away, are “tantalizing signs of geology on Pluto”. “It is just amazing what we are seeing now. It was a gradual approach and every […]
APRIL 30 (Reuters) — National Aeronautics and Space Administration’s (NASA’s) Pluto-bound New Horizons spacecraft has spotted surface features on the icy world, including a possible polar cap, images released on Wednesday show. With 60 million miles (97 million km) left to go before its July 14, 2015, encounter, New Horizons already has been able to make out surprising light and dark patches on the surface of Pluto, which is currently more than 32 times farther away from […]
