Astronomers using NASA’s Hubble Space Telescope have imaged what may be water vapor plumes erupting off the surface of Jupiter’s moon Europa. This finding bolsters other Hubble observations suggesting the icy moon erupts with high altitude water vapor plumes.

Tectonically Active Planet Mercury
New NASA-funded research suggests that Mercury is contracting even today, joining Earth as a tectonically active planet. Images obtained by NASA’s MESSENGER spacecraft reveal previously undetected small fault scarps— cliff-like landforms that resemble stair steps.

Practicing Orion Spacecraft Recovery After Splashdown
A group of U.S. Navy divers, Air Force pararescuemen and Coast Guard rescue swimmers practice Orion underway recovery techniques in the Neutral Buoyancy Laboratory at NASA’s Johnson Space Center to prepare for the first test flight of an uncrewed Orion spacecraft with the agency’s Space Launch System rocket during Exploration Mission (EM-1).

One Billion Base Pairs Sequenced on the Space Station
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.

NASA's IceBridge Observes Effects of Summer Melt on Greenland Ice Sheet
NASA’s IceBridge, an airborne survey of polar ice, flew over the Helheim/Kangerdlugssuaq region of Greenland on Sept. 11, 2016. This photograph from the flight captures Greenland’s Steenstrup Glacier, with the midmorning sun glinting off of the Denmark Strait in the background.

Infrared Echoes of a Black Hole Eating a Star
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.
