Nola was born in the southern savanna woodlands of Sudan. In the mid-1970s she was captured to protect her from poachers, and in 1989 she moved to the San Diego Zoo. She shared her enclosure with buffalo, giraffes and gazelles, and enjoyed daily belly scratches. 

In 1990, a male rhinoceros named Angalifu joined Nola in San Diego, but she wasn’t interested in him. After hormone treatments, she mated with another male named Saut, but never became pregnant.

Saut died in 2004. Angalifu died last year. Nola was getting older, and suffering from a bacterial infection. Yesterday the zoo announced:

In the last 24 hours, Nola’s condition worsened and we made the difficult decision to euthanize her. We’re absolutely devastated by this loss, but resolved to fight even harder to #EndExtinction.

With the death of Nola this weekend, the northern white rhinoceros inches closer to true extinction. But it became extinct in the wild 2008, and the remaining rhinos all have issues that prevent them from reproducing. Still, there are plans to resurrect the subspecies using a preserved egg and sperm. The San Diego Zoo’s Institute has pledged $2 million to this difficult project. 

And there is reason to be hopeful. A cousin subspecies, the southern white rhino, has seen its population blossom from 20 to 20,000 in the last century thanks to the intervention of humans.

skunkbear:

Vox’s Joss Fong put together a beautiful video pairing the images from the Voyager Golden Records (learn more about them here) with words from Carl Sagan and music from Blind Willie Johnson. The first image was a simple “calibrating circle” used in this post’s title.

There’s something powerful about this collection of images – this small attempt to sum up human existence. Carl Sagan said:

The spacecraft will be encountered and the record played only if there are advanced space-faring civilizations in interstellar space. But the launching of this ‘bottle’ into the cosmic ‘ocean’ says something very hopeful about life on this planet.

If we sent a time capsule to the aliens today, what would you want to include?
