The Loop I Bubble is located roughly 100 parsecs or roughly 330 light years from our Sun.
Famous quotes containing the word bubble:
“While this America settles in the mould of its vulgarity, heavily
thickening to empire,
And protest, only a bubble in the molten mass, pops and sighs out,
and the mass hardens,”
—Robinson Jeffers (1887–1962)
