Drudis [3] Explanation: Massive stars profoundly affect their galactic environments. Churning and mixing interstellar clouds of gas and dust, stars -- most notably those upwards of tens of times the mass of our Sun -- leave their mark on the compositions [4] and locations [5] of future generations of stars [6] . Dramatic evidence of this is illustrated in our neighboring galaxy, the Large Magellanic Cloud [7] (LMC), by the featured nebula, Henize 70 [8] (also known as N70 and DEM301). Henize 70 [9] is actually a luminous superbubble of interstellar gas about 300 light-years in diameter, blown by winds [10] from hot, massive stars and supernova explosions [11] , with its interior filled with tenuous hot and expanding gas. Because superbubble [12] s can expand through an entire galaxy, they offer humanity [13] a chance to explore the connection between the lifecycles of stars and the evolution of galaxies [14] ..
