Stellar embryos in nearby dwarf galaxy contain surprisingly complex organic molecules

The nearby dwarf galaxy known as the Large Magellanic Cloud (LMC) is a chemically primitive place. Unlike the Milky Way, this semi-spiral collection of a few tens-of-billions of stars lacks our galaxy’s rich abundance of heavy elements, like carbon, oxygen, and nitrogen. With such a dearth of heavy elements, astronomers predict that the LMC should contain a comparatively paltry amount of complex carbon-based molecules. Previous observations of the LMC seem to support that view. New observations have uncovered the surprisingly clear chemical ‘fingerprints’ of the complex organic molecules methanol, dimethyl ether, and methyl formate. Though previous observations found hints of methanol in the LMC, the latter two are unprecedented findings and stand as the most complex molecules ever conclusively detected outside of our galaxy. …read more
