In conjunction with Galileo's birthday on Feb. 15, NASA is releasing images from its Great Observatories -- the Hubble Space Telescope, Spitzer Space Telescope, and Chandra X-ray Observatory -- to more than 100 planetariums, museums, nature centers, and schools across the country.
The selected sites will unveil a large, 9-square-foot print of the spiral galaxy Messier 101 that combines the optical view of Hubble, the infrared view of Spitzer, and the X-ray view of Chandra into one multiwavelength picture. "It's like using your eyes, night vision goggles, and X-ray vision all at the same time," said Dr. Hashima Hasan, lead scientist for the International Year of Astronomy at NASA Headquarters in Washington.
Participating institutions also will display a matched trio of Hubble, Spitzer, and Chandra images of Messier 101. Each image shows a different wavelength view of the galaxy that illustrates not only the different science each observatory conducts but also how far astronomy has come since Galileo.
Messier 101 is a spiral galaxy about 22 million light-years away in the constellation Ursa Major. It is larger than our own Milky Way galaxy but similar in many ways. Hubble's visible-light view shows off the swirls of bright stars and glowing gas that give Messier 101 its nickname "the Pinwheel Galaxy." In contrast, Spitzer's infrared-light image sees into the spiral arms and reveals the glow of dust lanes where dense clouds can collapse to form new stars. Chandra's X-ray uncovers the high-energy features in the galaxy, such as remnants of exploded stars or matter zooming around black holes. The juxtaposition of observations from these three telescopes provides an in-depth view of the galaxy for both astronomers and the public.
"The amazing scientific discoveries Galileo made four centuries ago are continued today by scientists using NASA's space observatories," said Denise Smith, the unveiling's project manager at the Space Telescope Science Institute in Baltimore. "NASA's Great Observatories are distributing huge prints of spectacular images so the public can share in the exploration and wonder of the universe."
The unveilings will take place Feb. 14-28 at 76 museums and 40 schools and universities nationwide, reaching both big cities and small towns. Sites are planning celebrations involving the public, schools, and local media.
The Astrophysics Division of NASA's Science Mission Directorate supports the International Year of Astronomy Great Observatories image unveiling. The project is a collaboration among the Space Telescope Science Institute, the Spitzer Science Center in Pasadena, Calif., and the Chandra X-ray Center in Cambridge, Mass.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
