NASA’s Cassini spacecraft and Hubble Space Telescope capture unique view of Saturn’s Auroras

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA trained several pairs of eyes on Saturn as the planet put on a dancing light show at its poles.

While NASA’s Hubble Space Telescope, orbiting around Earth, was able to observe the northern auroras in ultraviolet wavelengths, NASA’s Cassini spacecraft, orbiting around Saturn, got complementary close-up views in infrared, visible-light and ultraviolet wavelengths. Cassini could also see northern and southern parts of Saturn that don’t face Earth.

NASA astronomers to use Hubble, Spitzer, Herschel space telescopes to examine Burned Out Elliptical Galaxies

 

Written by Whitney Clavin

NASA - National Aeronautics and Space AdministrationPasadena, CA – Astronomers using NASA’s Hubble and Spitzer space telescopes, and Europe’s Herschel Space Observatory, have pieced together the evolutionary sequence of compact elliptical galaxies that erupted and burned out early in the history of the universe.

Enabled by Hubble’s infrared imaging capabilities, astronomers have assembled for the first time a representative spectroscopic sampling of ultra-compact, burned-out elliptical galaxies — galaxies whose star formation was finished when the universe was only 3 billion years old, less than a quarter of its current estimated age of 13.8 billion years.

This graphic shows the evolutionary sequence in the growth of massive elliptical galaxies over 13 billion years, as gleaned from space-based and ground-based telescopic observations. The growth of this class of galaxies is quickly driven by rapid star formation and mergers with other galaxies. Image Credit: NASA, ESA, S. Toft (Niels Bohr Institute), and A. Feild (STScI)

NASA says 2013 continued Climate Warming Trend

 

NASA’s Goddard Institute for Space Studies

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA scientists say 2013 tied with 2009 and 2006 for the seventh warmest year since 1880, continuing a long-term trend of rising global temperatures.

With the exception of 1998, the 10 warmest years in the 134-year record all have occurred since 2000, with 2010 and 2005 ranking as the warmest years on record.

NASA’s Kepler space telescope provides data on distant planets

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – More than three-quarters of the planet candidates discovered by NASA’s Kepler spacecraft have sizes ranging from that of Earth to that of Neptune, which is nearly four times as big as Earth.

Such planets dominate the galactic census but are not represented in our own solar system. Astronomers don’t know how they form or if they are made of rock, water or gas.

NASA’s Hubble Space Telescope discovers Asteroid with six tails similar to a Comet

 

Written by Dr. Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Astronomers viewing our 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. Designated P/2013 P5, the asteroid resembles a rotating lawn sprinkler.

“We were literally dumbfounded when we saw it,” said lead investigator David Jewitt of the University of California at Los Angeles. “Even more amazing, its tail structures change dramatically in just 13 days as it belches out dust. That also caught us by surprise. It’s hard to believe we’re looking at an asteroid.”

This NASA Hubble Space Telescope set of images reveals a never-before-seen set of six comet-like tails radiating from a body in the asteroid belt, designated P/2013 P5.

NASA’s Dawn Spacecraft observations of asteroid Vesta help scientists determine accuracy of Space and Ground based Telescopes

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – Tantalized by images from NASA’s Hubble Space Telescope and ground-based data, scientists thought the giant asteroid Vesta deserved a closer look. They got a chance to do that in 2011 and 2012, when NASA’s Dawn spacecraft orbited the giant asteroid, and they were able to check earlier conclusions.

A new study involving Dawn’s observations during that time period demonstrates how this relationship works with Hubble and ground-based telescopes to clarify our understanding of a solar system object.

One Man’s Medal: The Story of George Nishimura-Part 4

 
George Nishimura

George Nishimura

Clarksville, TN – In researching this story, and getting to know the life of George Nishimura, I’ve learned so much about World War II that I have never known before.  His personal handwritten account of his life is an amazing recollection of what it was like growing up in a country that came under attack from the Japanese, and how he wanted to “do something” to help the Americans fight back.

George Nishimura served his country in the best way he knew how.  He followed orders and did what he was told.  The Japanese-American soldiers who volunteered to serve, were treated differently.  There was a feeling of apprehension by most Americans, who wondered how can the “Japs” be the good guy and bad? «Read the rest of this article»
