Seven superclouds sit just beyond the solar system

SMRTR summary

Scientists discovered seven massive gas structures called superclouds just beyond our solar system. These parallel, wave-patterned strings of gas (five newly identified) are likely "mothers" to star-forming regions and represent our largest cosmic neighbors. The superclouds range from 3,000-8,000 light-years long with masses up to 3.5 million times the sun's, containing most nearby stellar nurseries along their central axes.
