Interstellar Cloud

NASA’s Hubble Space Telescope captured this photo of a Wolf-Rayet star named WR 31a, encircled by a deep blue cloud of dust, hydrogen, and other gases that’s expanding at about 136,700 miles per hour. The star only has a lifespan of a few hundred thousand years, which is, as NASA put it, “the blink of an eye in cosmic terms.”

Gorilla Survives Rare C-section

A baby western lowland gorilla at Bristol Zoo Gardens was born via a rare emergency c-section, a procedure that has only been performed on gorillas a handful of times, the zoo says. Both mother and child survived, and a team of gorilla-keepers are hand-rearing the baby to ensure her continued well-being.

Life Blooms in the Face of Death

Death Valley, one of the driest, hottest regions in the United States, is experiencing an unusually spectacular display of wildflowers after a particularly rainy October. The blooms are some of the best the park has experienced in a decade, according to the National Park Service.

Top of the World

Scott Kelly’s nearly year-long mission in space is almost over, but hopefully he’ll continue to post stunning images like this one of the Himalayas until the very end.

Starry Night

The European Southern Observatory released a photo mapping the entire Milky Way as seen from Chile. The photo was taken using the APEX telescope, a tool that astronomers use to study the cold universe, regions of the galaxy where gas and dust are only a few degrees above absolute zero.

A Fruity Snack

Symbio Wildlife Park released a video of baby cotton top tamarin monkeys cooling off in Sydney’s blistering heat with a fruit popsicle.

Technicolor Cell

Researchers captured highly detailed, color-coded photos of cells’ borders by freezing the cells and slicing them into slivers just a few hundred nanometers wide. Their detailed images could help scientists better understand how cell parts fit together and function as a whole.

Baby Indian Rhino

The Toronto Zoo announced the birth of a baby Indian rhinoceros this week, an exciting development given that the species is considered vulnerable. Although the rhino species once populated the entire northern portion of the Indian subcontinent, there are now only about 2,000 left in the wild, according to the zoo.

American Lobster Larva

This incredible photo of a three-week-old lobster larva captures all the details of the tiny organism right down to the whisper-thin hairs on its legs. The photo is one of the winners of the 2016 Vizzies, a Popular Science and National Science Foundation contest celebrating the year’s best science imagery.

Frozen Canyons

NASA released an enhanced photo of Pluto’s icy canyons on its northern pole.
