Mercury wags its tail

The hot planet Mercury has been showing off its comet-like tail to NASA satellites recently. Scientists at Boston University said it has been known that Mercury exhibits comet-like features, with a coma of gas surrounding the planet and a very long tail extending away from the Sun. The scientists have been studying images from NASA's STEREO satellites which are designed to view the escaping atmosphere of the Sun. The new images will let them gain a ton more knowledge about the makeundefinedup of the planet's gases.
