Seen in a composite picture released November 7, the star cluster Cygnus
OB2—the closest massive stellar nursery to Earth—glows with the energy of
hundreds of young stars.For
the picture, NASA's Chandra
X-ray Observatory stared across some 5,000 light-years and captured 1,500 stars
pumping out x-rays (shown in blue). The Spitzer Space
Telescope offered infrared imagery (red), and the Earth-based Isaac Newton Telescope
provided optical wavelength-views (orange). (See the same view in x-ray,
infrared, or optical wavelengths.)
Fascinating, not even the most advanced in my youth could have thought this
would be possible! Takes my breath away......
