Image description: Brand new manufactured parts give off gases from chemicals and residual solvents involved in their manufacture in a process known as outgassing. These gases filling your cabin are the cause of that familiar “new car smell.”
However, if your new car were actually a new spaceship full of extremely sensitive instruments and astronauts unable to roll down the windows, those gases could be a big problem.
In this image, a NASA technologist studies a paint sample as part of research that has resulted in a low-cost technique for preventing damage from outgassed contaminants. Find out more.

Image description: This collage of solar images from NASA’s Solar Dynamics Observatory (SDO) shows how observations of the sun in different wavelengths helps highlight different aspects of the sun’s surface and atmosphere. (The collage also includes images from other SDO instruments that display magnetic and Doppler information.) Credit: NASA/SDO/Goddard Space Flight Center.

Image description: Camelopardalis, or U Cam for short, is a star nearing the end of its life. As stars run low on fuel, they become unstable. Every few thousand years, U Cam coughs out a nearly spherical shell of gas as a layer of helium around its core begins to fuse. The gas ejected in the star’s latest eruption is clearly visible in this picture as a faint bubble of gas surrounding the star.
