A NASA camera on the Deep Space Climate Observatory (DSCOVR) satellite has returned its first view of the entire sunlit side of Earth from one million miles away. The color images of Earth from NASA’s Earth Polychromatic Imaging Camera (EPIC) are generated by combining three separate images to create a photographic-quality image. The camera takes…
By Glynn Wilson – After a decade-long journey through the solar system, NASA’s New Horizons spacecraft made its closest approach to Pluto on Tuesday, making it the first-ever space mission to explore a world so far from Earth. The craft passed 7,750 miles above the surface of the dwarf planet, roughly the distance from New…
The latest data from NASA shows changes in global temperature and precipitation through the year 2,100 depending on how much greenhouse gas emissions continue to plague the Earth’s atmosphere. The dataset, available to the public, shows projected changes worldwide on a regional level in response to different scenarios of increasing carbon dioxide simulated by 21…
WASHINGTON, D.C. – The National Aeronautics and Space Administration will celebrate the 45th annual Earth Day April 17-22 with a variety of live and online activities to engage the public in the agency’s mission to better understand and protect the planet. The agency uses the vantage point of space to increase understanding of the planet,…
NASA is beginning work on a new satellite mission that will extend critical climate measurements of Earth’s oceans and atmosphere and advance studies of the impact of environmental changes on ocean health, fisheries and the carbon cycle. Tentatively scheduled to launch in 2022, the Pre-Aerosol Clouds and ocean Ecosystem (PACE) mission will study Earth’s aquatic…
By Glynn Wilson – Droughts in the Southwestern United States and the Central Plains during the last half of the 21st century could be drier and longer than conditions in the past 1,000 years, according to a new study just released by the National Aeronautics and Space Administration. The study, based on projections from climate…
By Glynn Wilson – The year 2014 ranks as Earth’s warmest on record since 1880, according to two separate analyses by scientists from NASA and National Oceanic and Atmospheric Administration. The 10 warmest years in the instrumental record, with the exception of 1998, have now occurred since 2000, they say in a release just out…
WASHINGTON, D.C. – NASA launched its sixth consecutive year of Antarctica overflights to study changes that could be a significant harbinger of climate change due to global warming. The science craft measures the ice sheet over all, the glaciers and the surrounding sea ice for changes that could provide scientists with the latest up-to-date information…
Earth’s atmosphere contains an unexpectedly large amount of an ozone-depleting chemical compound from an unknown source, surpassingly, decades after the compound was banned worldwide, according to new research out from NASA published in the Aug. 18 issue of Geophysical Research Letters. Carbon tetrachloride (CCl4), once used in dry cleaning and fire-extinguishers, was regulated in 1987…
A new study by scientists at NASA and the University of California at Irvine finds more than 75 percent of the water loss in the drought-stricken Colorado River Basin since late 2004 came from underground sources. The extent of groundwater loss may pose a greater threat to the water supply of the western United States…
Astronomers using NASA’s Hubble Space Telescope have gone looking for water vapor in the atmospheres of three planets orbiting stars similar to the sun — and have come up nearly dry. The three planets, known as HD 189733b, HD 209458b, and WASP-12b, are between 60 and 900 light-years away from Earth and were thought to…
NASA embarked this week on a coordinated ship and aircraft observation campaign off the Atlantic coast of the United States in an effort to advance space-based capabilities for monitoring microscopic plants that form the base of the marine food chain. Phytoplankton, tiny ocean plants that absorb carbon dioxide and deliver oxygen to Earth’s atmosphere, play…
They may be little, but they pack a big star-forming punch. New observations from NASA’s Hubble Space Telescope show small galaxies, also known as dwarf galaxies, are responsible for forming a large proportion of the universe’s stars. Studying this early epoch of the universe’s history is critical to fully understanding how these stars formed and…
Astronomers using NASA’s Hubble Space Telescope have assembled a comprehensive picture of the evolving universe – among the most colorful deep space images ever captured by the 24-year-old telescope. Researchers say the image, in new study called the Ultraviolet Coverage of the Hubble Ultra Deep Field, provides the missing link in star formation. The Hubble…
A new study by researchers at NASA and the University of California, Irvine, finds a rapidly melting section of the West Antarctic Ice Sheet appears to be in an irreversible state of decline, with nothing to stop the glaciers in this area from melting into the sea. The study presents multiple lines of evidence, incorporating…
NASA’s Wide-field Infrared Survey Explorer and Spitzer Space Telescope have discovered what appears to be the coldest “brown dwarf” known — a dim, star-like body that, surprisingly, is as frosty as Earth’s North Pole. Images from the space telescopes also pinpointed the object’s distance to 7.2 light-years away, earning it the title for fourth closest…
By Glynn Wilson – Earth’s climate will likely continue in a man-made warming trend for the remainder of the 21st century on track with previous estimates, despite the recent slowdown in the rate of global warming, a new NASA study concludes. The latest research hinges on a new and more detailed calculation of the sensitivity…
By Glynn Wilson – Astronomers have accomplished the first direct measurement of the spin of a distant black hole, an important advance for understanding how black holes grow over time, scientists say. The research suggests that this black hole grew by gradually merging material rather than pulling in material in from different directions. NASA’s Chandra…
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…
