“One Billion Base Pairs Sequenced on the Space Station” was uploaded to Flickr

NASA astronaut Kate Rubins checks a sample for air bubbles prior to loading it in the biomolecule sequencer. When Rubins’ expedition began, zero base pairs of DNA had been sequenced in space. Within just a few weeks, she and the Biomolecule Sequencer team had sequenced their one billionth base of DNA aboard the orbiting laboratory. via NASA ift.tt/2cRwlW4

“Infrared Echoes of a Black Hole Eating a Star” was uploaded to Flickr

This illustration shows a glowing stream of material from a star, disrupted as it was being devoured by a supermassive black hole. The feeding black hole is surrounded by a ring of dust. This dust was previously illuminated by flares of high-energy radiation from the feeding black hole, and is now shown re-radiating some of that energy. via NASA ift.tt/2cIf9V1
