Exoplanets Soon to Gleam in the Eye of NESSI

The New Mexico Institute of Mining and Technology’s 2.4-meter (7.9-foot) Magdalena Ridge Observatory in Socorro County, N.M. Image credit: New Mexico Tech  The New Mexico Exoplanet Spectroscopic Survey Instrument (NESSI) will soon get its first “taste” of exoplanets, helping astronomers decipher their chemical composition. Exoplanets are planets that orbit stars beyond our sun. NESSI got its first peek at the sky on April 3, 2014. It looked at Pollux, a star in the Gemini constellation, and Arcturus, in the Boötes constellation, confirming that all modes of the instrument are working. “After five years of development, it’s really exciting to turn…
