E. E. BARNARD
E. E. BARNARD
USA (1857 - 1923)
Best known for his discovery of Barnard's star in 1916, Edward Emerson Barnard was a gifted astronomer who grew up with little formal education. In 1876, he purchased his first telescope, a 5-inch refractor and discovered his first comet in 1881. In 1892, he discovered Amalthea, the fifth moon of Jupiter, making him the first to discover a new Jovian moon since Galileo in 1609. After joining Yerkes Observatory at the University of Chicago in 1895, Barnard spent great amounts of time photographing the Milky Way. Posthumously, his photographs were published in 1927 as A Photographic Atlas of Selected Regions of the Milky Way.

ALMA's spectrum range
Catherine Cesarsky - International Astronomical Union

ALMA will work at the millimeter and sub-millimeter range, which means the wavelengths, these are microwaves and their wavelength is of that size, between one millimeter to a tenth of a millimeter, .3 millimeters, actually, for ALMA. This is a wavelength that has been least explored in astronomy these days, and so the potential for discovery is absolutely enormous.
