Dark comets have been observed by many telescopes over the years, but this time, NASA is uncertain about their origin. Unlike regular comets, these objects resemble an asteroid, but move like comets.

NASA's GRACE satellite detected a large gravity anomaly over the Atlantic Ocean. Meanwhile, Earth-based observatories saw a rapid shift in the planet's geomagnetic field.

In May 1964, Arno Penzias and Robert Wilson were testing how radio waves bounced off balloon satellites developed by Bell Telephone Laboratories. But they kept getting an unpleasant hissing noise, in ...
