Image description: NASA announces that Voyager 1 is officially the first human-made object to venture into interstellar, or “deep” space.
The 36-year-old probe is 12 billion miles from our sun, and has been traveling in plasma present in the space between stars for about a year.

Image description: This photo of star trails was taken by Expedition 31 Flight Engineer Don Pettit on the International Space Station.
Pettit used the following photographic techniques to create the images: “My star trail images are made by taking a time exposure of about 10 to 15 minutes. However, with modern digital cameras, 30 seconds is about the longest exposure possible, due to electronic detector noise effectively snowing out the image. To achieve the longer exposures I do what many amateur astronomers do. I take multiple 30-second exposures, then ‘stack’ them using imaging software, thus producing the longer exposure.”

Image description: NASA engineer Acey Herrera checks out copper test wires inside the thermal shield of the Mid-Infrared Instrument, known as MIRI, that will fly aboard NASA’s James Webb Space Telescope.
The shield is designed to protect the vital MIRI instrument from excess heat.
At the time of the photo, the thermal shield was about to go through rigorous environmental testing to ensure it can perform properly in the extreme cold temperatures that it will encounter in space. Learn more about the tests.
