NASA’S NEW SPACE TELESCOPE TO RE­VEAL THE LAST DE­TAILS

Science Illustrated - - SPACE -

When NASA’s James Webb space telescope is launched next year, the anal­y­sis of the plan­ets' at­mos­pheres will be­gin. The method is spec­troscopy, by which the telescope mea­sures the wave­lengths of the light from the star that passes through a planet's at­mos­phere. Dif­fer­ent mol­e­cules ab­sorb and dim spe­cific wave-lengths of the light. Based on this, sci­en­tists can tell the sub­stances in the at­mos­phere such as meth­ane, which is emit­ted by bac­te­ria.
