...great interstellar clouds also contain another kind of fertilizer. In 1963 a team of researchers from the Massachusetts Institute of Technology and the Lincoln Laboratory used a radio telescope to discover the hydroxyl radical (two-thirds of the water molecule) in space. Since then, more than three dozen molecules have been found floating in the galactic clouds, including those of methane, formaldehyde, ammonia, hydrogen cyanide, ethyl alcohol and carbon monoxide...

...Frank J. Kerr of the University of Maryland. What makes the situation even worse, he explains, is that the satellites use a portion of the radio spectrum especially important to radio astronomy. SMS-1, for instance, operates near the 18-cm. band, which is the natural wave length of hydroxyl, one of the first molecules discovered in space. It is from the signals of the hydroxyl molecule (which consists of one atom of hydrogen and one of oxygen) that radio astronomers have been learning about star formation and the nature of the clouds of gases between the stars...

...single antenna with a diameter equal to the distance between the two antennas (up to 3,500 ft.). Then, aiming his twin instruments at two particularly powerful sources of radio energy, the galaxies M82 and NGC 253, * he quickly found what he was looking for: the characteristic signature of hydroxyl radicals, simple molecules composed of a single hydrogen and a single oxygen atom...
