Hubble detects protective shield defending a pair of dwarf galaxies
For billions of years, the Milky Way's largest satellite galaxies—the Large and Small Magellanic Clouds—have followed a perilous journey. Orbiting one another as they are pulled in toward our home galaxy, they have begun to unravel, leaving behind trails of gaseous debris. And yet—to the puzzlement of astronomers—these dwarf galaxies remain intact, with ongoing vigorous star formation.
Hubble Detects Protective Shield Defending a Pair of Dwarf Galaxies
Recent theoretical predictions suggest that the Large and Small Magellanic Clouds must be protected by a pervasive shield that prevents the Milky Way from removing their essential star-forming gas.
