Analysis of near-infrared data from the European Southern Observatory’s VISTA telescope provides evidence for a dark-matter-dominated dwarf galaxy 300,000 light-years away predicted to exist in 2009.
In 2014, a quite remarkable collage was released by scientists who used NASA’s Spitzer Space Telescope to image the entirety of the Milky Way in infrared light.
Astronomers recently found that a galaxy about 30 million light-years away nicknamed Leoncino, or “little lion,” contains the lowest level of heavy chemical elements, or “metals,” ever observed in a gravitationally bound system of stars. The elemental make-up of metal-poor galaxies is very close to that of the early universe.
