Galaxies in the Mid-Infrared

The Mid-Infrared is good to study hot gas and dust in close galaxies. The Spitzer Space Telescope did already study the gas in close galaxies, like the spiral Andromeda galaxy or the dwarf galaxies Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC). Beside these very close galaxies, spitzer did image more distant galaxies, as… Continue reading Galaxies in the Mid-Infrared
