This galaxy is so large, so fully-formed, astronomers say it shouldn’t exist at all. It’s called a “grand-design” spiral galaxy, and unlike most galaxies of its kind, this one is old. Like, really, really old. According to a new study conducted by researchers using NASA’s Hubble Telescope, it dates back roughly 10.7-billion years — and that makes it the most ancient spiral galaxy we’ve ever discovered.
"The fact that this galaxy exists is astounding," said University of Toronto’s David Law, lead author of the study. "Current wisdom holds that such ‘grand-design’ spiral galaxies simply didn’t exist at such an early time in the history of the universe."
The reason Stephen Hawking bet against the Higgs Boson is the same reason BX442 is the best kind of discovery; not only does this galaxy set a new benchmark by way of its cosmic seniority, it’s also super weird — weirder than what anyone thought was possible. In science, these are the finds that help us rework our understanding of nature, the discoveries that force us to step back from what we thought we knew, re-assess our preconceived notions, and bring forth a newer, more fully formed view of our Universe..
