Herschel Telescope Detects Water Vapor on Dwarf Planet

ceres1

Scientists using the Herschel space observatory have made the first definitive detection of water vapor on the largest and roundest object in the asteroid belt on a dwarf planet, a body in the solar system bigger than an asteroid but smaller than a planet, called Ceres. Plumes of water vapor are thought to shoot up…

NASA Confirms Sustained Long-Term Climate Warming Trend

2013updates_nodates_lastStep_2009_2013

By Glynn Wilson – Scientists now say 2013 tied with 2009 and 2006 for the seventh warmest year since 1880, continuing a long-term trend of rising global temperatures, according to a new report out from the National Aeronautics and Space Administration (NASA). With the exception of 1998, the 10 warmest years in the 134-year record…

NASA Spacecraft Spots Its First New Asteroid Near Earth

By Glynn Wilson – A reactivated NASA spacecraft designed to identify the population of potentially threatening near-Earth objects has spotted a new asteroid about 27 million miles (43 million kilometers) from Earth. Based on its infrared brightness, scientists estimate it to be roughly 0.4 miles (650 meters) in diameter and extremely dark, like a piece…

NASA’s Cassini Spacecraft Gets High Resolution Views of Saturn Hexagon

pia17652-640

NASA’s Cassini spacecraft has obtained the highest-resolution movie yet of a unique six-sided jet stream, known as the hexagon, around Saturn’s north pole. This is the first hexagon movie of its kind, using color filters, and the first to show a complete view of the top of Saturn down to about 70 degrees latitude. Spanning…

NASA’s Hubble Photographs Asteroid Spouting Six Comet-Like Tails

NASA_asteroids1013a

Astronomers viewing the solar system’s asteroid belt with NASA’s Hubble Space Telescope have seen for the first time an asteroid with six comet-like tails of dust radiating from it like spokes on a wheel. Unlike all other known asteroids, which appear simply as tiny points of light, this, designated P/2013 P5, resembles a rotating lawn…

NASA Study Reveals Industrial Soot’s Role in Glacier Retreat

A NASA-led team of scientists has uncovered strong evidence that soot from a rapidly industrializing Europe caused the abrupt retreat of mountain glaciers in the European Alps that began in the 1860s, a period often thought of as the end of the Little Ice Age, according to a new peer reviewed study published Sept. 3…

Tropical Ecosystems Boost Carbon Dioxide as Temperatures Rise

By Glynn Wilson – NASA scientists and an international team of researchers have found tropical ecosystems can generate significant carbon dioxide when temperatures rise, unlike ecosystems in other parts of the world, further exacerbating global warming and climate change, according to a new study. The researchers discovered a temperature increase of just 1 degree Celsius…

Climate Scientist James Hansen Announces Retirement from NASA

Pledges Full Time Activism on Climate Change Policy – By Glynn Wilson – James E. Hansen, perhaps the most outspoken scientist on global warming, is stepping down from his federal position at NASA’s Goddard Institute for Space Studies after 46 years at the agency to engage full time on the issue, citing a moral obligation…

NASA Cams Capture Massive Sun Storm

No Threat to Earth, This Time – NASA/SDO – The National Aeronautics and Space Administration captured video footage of massive storms on the sun last week that could have caused major problems on earth, including shutting down entire electrical grids – if it had occurred on the other side. The action was captured Nov. 16…

On the South Lawn, A White House 'Star Party'

A reader from Montana with a relative in attendance sent us this link this morning, an amazing piece of footage showing we now have a president in the White House who not only knows who Galileo was, but opens up the White House lawn to kids interested in something other than Easter eggs — the…

Water Geysers on Saturn Moon Suggest Life?

NASA Spray Above Enceladus III, NASA Images The orbiting Cassini spacecraft has spotted what appear to be water geysers on one of Saturn’s icy moons, raising the tantalizing possibility that the celestial object harbors life, according to the Associated Press. The surprising images from the moon Enceladus represent some of the most dramatic evidence yet…
