A Creator's Possible Calling Card

The cosmic microwave background (CMB) is leftover radiation from the Big Bang redshifted (stretched) by the universe's expansion into the microwave region of the spectrum. In this image NASA's Wilkinson Microwave Anisotropy Probe (WMAP) records minuscule temperature fluctuations in the CMB as different colors. In principle, an advanced civilization could…

Bursting Neutron Star Mystery

An artist depicts a neutron star. These objects are the dead cores of stars that exploded as supernovae. They cram more than a Sun's worth of mass into a ball only about 20 kilometers (12 miles) across, achieving extraordinarily high densities. Powerful magnetic field lines (blue) thread through these objects.…
