Albert Einstein, the Humanitarian

Along with his renowned scientific accomplishments, Albert Einstein should be acknowledged for his humanitarian struggles to achieve peace and international cooperation.

This eerie photograph is a close-up of the inner parts of the Crab nebula. The Crab pulsar (seen here at the left of the pair of stars near the center of the frame) is the collapsed core of the exploded star. The pulsar itself is a rapidly rotating neutron star, an object only about 10 kilometers (6 miles) across, but containing more mass than our Sun.
