Postal Service Makes the Sun Shine Bright With Forever Stamps
The U.S. Postal Service issued the Sun Science stamps last month! Via usps
The Postal Service highlights stunning images of the sun that celebrate the science behind the ongoing exploration of our nearest star.
Printed with a foil treatment that adds a glimmer to the stamps, the images on these stamps come from NASA’s Solar Dynamics Observatory, a spacecraft launched in February 2010 to keep a constant watch on the sun from geosynchronous orbit above Earth. The striking colors in these images do not represent the actual colors of the sun as perceived by human eyesight. Instead, each image is colorized by NASA according to different wavelengths that reveal or highlight specific features of the sun’s activity.
One of the stamps highlights sunspots, two feature images of coronal holes, two show coronal loops, two depict plasma blasts, one is a view of an active sun that emphasizes its magnetic fields, and two show different views of a solar flare.
