Hubble has spotted an ancient galaxy that shouldn’t exist
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..

Another Look at the Newly Discovered Hot Pink Slug form Australia
by Carrie Arnold
He’s big. He’s slimy. And he’s … neon pink?! Meet Triboniophorus aff. graeffei, a new species of 8-inch-long (20-cm-long) slug that’s found only on one Australian mountain.
Scientists already knew that a bright-pink slug lived on Mount Kaputar (map), thinking it was a variety of the red triangle slug, a species common along the east coast of Australia. But new research shows that the colorful critter is actually its own species, said Australia’s National Parks and Wildlife Service ranger Michael Murphy.
“Recent morphological and genetics work by a researcher working on this slug family—the Athorcophoridae—has indicated the Kaputar slugs are a unique species endemic to Mount Kaputar and the only representative of this family in inland Australia,” said Murphy, who’s been stationed on Mount Kaputar for 20 years…
