For thousands of years, fluffy white dogs could be found across the Pacific Northwest. Their exceptionally soft, crimpy hair was shorn like sheep’s wool, spun into yarn, and woven into blankets and robes by indigenous women who carefully tended them in communities across Coast Salish territory. But a hundred years ago, the woolly dog quietly vanished. Why?

Today, the only known pelt of this extinct breed is in the collections of the Smithsonian’s National Museum of Natural History, and it might hold some answers. Through collaborate research combining Western science with Indigenous knowledge, we delve into this animal’s genome to learn the real story of the woolly dog’s disappearance.

Hitch a ride on the Chandra X-ray Observatory as it scours deep space for some of the most enigmatic and misunderstood objects in the universe: black holes. What are they good for? Absolutely something.

This is the second episode of a two-part journey celebrating the 25th anniversary of the Chandra X-ray Observatory and the Smithsonian Astrophysical Observatory's operation of the space telescope.

Join us this summer for a cosmic journey full of events and virtual resources from around the Smithsonian that will transport you from our closest star, the sun, to the far reaches of the universe.

Black holes could unlock the mysteries of creation and live at the heart of nearly every galaxy. But these invisible balls of extremely dense matter have never been fully understood, especially when they were only a theory. We travel through a cosmic wormhole back to the 1930s to learn how the first astrophysicist to successfully theorize a black hole, Subrahmanyan Chandrasekhar, was ridiculed and rejected by his scientific community.
