SIM will also measure the motions of stars near the center of many galaxies, which should tell us whether they harbor enormous black holes at their core.
Based on data taken by NASA's Chandra X-ray Observatory, the model takes into account how energy flows between two regions around the black hole — an inner core close to the boundary beyond which light can not escape (the event horizon) and an outer ring that extends far out and includes the massive young stars lurking near the black hole.
This unusually compact cloud of dust and gas near the center of the Milky Way in the direction of the constellation Sagittarius is energized by a hot young star at its core, and it's a veritable alphabet soup of molecules.
It spends much of its time monitoring the light from around 60 of the nearest ultracool dwarf stars and brown dwarfs («stars» which are not quite massive enough to initiate sustained nuclear fusion in their cores), looking for evidence of planetary transits.
From Pluto in this scale model, to reach the nearest star system, Alpha Centauri, you'd have to travel some 2900 kilometers: roughly the distance between Memphis and San Francisco, or about how far you'd have to dig straight down into the Earth before reaching its outer core.
