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…
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…
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 – 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…
