Extraterrestrial Substances

(Extra Credit)

Many of the substances found on the Earth are also found on other planets as well as in or on moons, comets, asteroids, meteors and stars, Some of these substances have even been found in interstellar space. Helium was originally discovered as being one of the elements making up our Sun before helium deposits were located on the Earth.

Different types of telescopes have now been joined by probes and rovers, like Pathfinder and Spirit on Mars, in the search for extraterrestrial substances.
