In this image, one of the radiation detectors for the Radi-N2 experiment floats in the space station. This device will help researchers explore the radition risk to humans in space. Neutrons make up a significant part of the radiation exposure in low-Earth orbit, but have not been well characterized. Radi-N2, a Canadian Space Agency investigation, uses bubbl...
This image from the NASA/ESA Hubble Space Telescope features the spectacular galaxy NGC 2442, nicknamed the Meathook galaxy owing to its extremely asymmetrical and irregular shape. This galaxy was host to a supernova explosion spotted in March 2015, known as SN 2015F, that was created by a white dwarf star. The white dwarf was part of a binary star system an...
The crew aboard the International Space Station spotted Hurricane Genevieve off Mexico’s Pacific coast on Aug. 19, 2020. NASA’s Suomi NPP satellite also kept an eye on Hurricane Genevieve overnight and provided infrared imagery to forecasters who were monitoring the storm’s strength, structure and size. Because Genevieve is close to the coast of ...
We’re celebrating National Aviation Day! After all, we are the National Aeronautics and Space Administration. Aviation and aeronautics are as much a part of our mission as space travel. This visualization is generated from a supercomputer simulation of the X-57 “Maxwell” electric experimental aircraft. Just as electric cars are becoming more and more c...
Eleven years after the launch of the first H-II Transfer cargo vehicle (HTV) to the International Space Station, the Japan Aerospace Exploration Agency’s (JAXA’s) HTV-9 will depart the orbital laboratory Tuesday, Aug. 18. This will be the final station departure of JAXA’s Kounotori, or “white stork,” model cargo craft, nine of which have delivered more than ...
Hi-RISE, the High-Resolution Imaging Science Experiment camera aboard NASA’s Mars Reconnaissance Orbiter (MRO) captured this avalanche plunging down a 1,640-foot-tall (500-meter-tall) cliff on May 29, 2019. The image also reveals layers at Mars’ north pole during spring. As temperatures increase and vaporize ice, the destabilized ice blocks break...
We all have to do our housekeeping chores, even when we command the crew aboard the International Space Station. This past weekend, NASA astronaut and Expedition 63 Commander Chris Cassidy was no exception as he collected trash for disposal during weekend housekeeping activities.

Technicians at NASA’s Kennedy Space Center in Florida are working to install an adapter that will connect the Orion spacecraft to its rocket for the Artemis I mission around the Moon. This is one of the final major hardware operations for Orion inside the Neil Armstrong Operations and Checkout Building prior to integration with the Space Launch System (SLS) ...
As of March 2020, our Mars Odyssey spacecraft has captured these six views of the Martian moon Phobos. The orbiter’s infrared camera, the Thermal Emission Imaging System (THEMIS), is used to measure temperature variations that provide insight into the physical properties and composition of the moon. Chronologically, the views represent waxing, waning a...
If humans could travel to this giant planet, we would see a world still glowing from the heat of its formation with a color reminiscent of a dark cherry blossom, a dull magenta. Using infrared data from the Subaru Telescope in Hawaii, astronomers discovered this gas giant orbiting a bright star named GJ 504 in 2013. Several times the mass of Jupiter and simi...
