Robert Leighton used military surplus photocells to cheaply construct a telescope that observed in this region of the EM spectrum and discovered new classes of protostars and supergiants. For 10 points each:
[10m] What region of the spectrum contains the J and K bands? The Roman Space Telescope will observe this region of the spectrum.
ANSWER: infrared [or IR]
[10h] Leighton further advanced observational astronomy by improving the design of Horace Babcock’s solar magnetograph, which led to his discovery of these phenomena. These seismic phenomena are caused by the Sun’s internal p-modes and are named for their period.
ANSWER: solar 5-minute oscillations [prompt on oscillations]
[10e] Later in his career at this lab, Leighton was Team Leader of the Imaging Science Investigations on the Mariner 4, 6, and 7 missions to Mars. This Pasadena-based lab is owned by NASA and administered by Caltech.
ANSWER: Jet Propulsion Laboratory [or JPL]
