Astrochemistry
<p><b >Astrochemistry</b> is the study of the abundance and reactions of <a href="http://en.wikipedia.org/wiki/Chemical_element" title="Chemical element" >chemical elements</a> and <a href="http://en.wikipedia.org/wiki/Molecule" title="Molecule" >molecules</a> in the universe, and their interaction with<a href="http://en.wikipedia.org/wiki/Radiation" title="Radiation" >radiation</a>.<sup class="Template-Fact" >[<i><a href="http://en.wikipedia.org/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed" >citation needed</a></i>]</sup> The discipline is an overlap of <a href="http://en.wikipedia.org/wiki/Astronomy" title="Astronomy" >astronomy</a> and <a href="http://en.wikipedia.org/wiki/Chemistry" title="Chemistry" >chemistry</a>. </p>
<p>
The word "astrochemistry" may be applied to both the <a href="http://en.wikipedia.org/wiki/Solar_System" title="Solar System" >Solar System</a> and the <a href="http://en.wikipedia.org/wiki/Interstellar_medium" title="Interstellar medium" >interstellar medium</a>. The study of the abundance of elements and isotope ratios in Solar System objects, such as <a href="http://en.wikipedia.org/wiki/Meteorite" title="Meteorite" >meteorites</a>, is also called <a href="http://en.wikipedia.org/wiki/Cosmochemistry" title="Cosmochemistry" >cosmochemistry</a>, while the study of interstellar atoms and molecules and their interaction with radiation is sometimes also called molecular astrophysics. The formation, atomic and chemical composition, evolution and fate of <a href="http://en.wikipedia.org/wiki/Molecular_cloud" title="Molecular cloud" >molecular gas clouds</a> is of special interest, because it is from these clouds that solar systems form.
