See the Serpent's Star City

摘要

The most impressive regions of the Milky Way return to prominence during the warm nights of early summer. The section surrounding our galaxy's center in Sagittarius teems with glowing clouds of gas and dust - stellar nurseries like the one that gave birth to our sun some 4.6 billion years ago. But this area also harbors an often-overlooked component of the Milky Way. Globular star clusters - vast collections that hold anywhere from tens of thousands to a few million suns - roam the periphery of our galaxy's central bulge. One of the best reaches its peak in the southern sky late on June evenings.
