Example Sentences

The Large Magellanic Cloud, located about 160,000 light-years from Earth, is an ideal environment for studying how stars form in conditions resembling those of the early universe.

From Science Daily

"The detection of icy COMs in the Large Magellanic Cloud provides evidence that these reactions can produce them effectively in a much harsher environment than in the solar neighborhood."

From Science Daily

"We currently only have one source in the Large Magellanic Cloud and only four sources with detection of these complex organic molecules in ices in the Milky Way. We need larger samples from both to confirm our initial results that indicate differences in COM abundances between these two galaxies," Sewilo said.

From Science Daily

"What we learn in the Large Magellanic Cloud, we can apply to understanding these more distant galaxies from when the universe was much younger. The harsh conditions tell us more about how complex organic chemistry can occur in these primitive environments where much fewer heavy elements like carbon, nitrogen and oxygen are available for chemical reactions."

From Science Daily

Methanol and methyl formate had already been observed in the gas phase within the Large Magellanic Cloud, but this is the first evidence that such molecules are also forming in the solid ice itself.
