Aurora borealis, and its southern counterpart, aurora australis, account for some of the most stunning natural events on Earth—but the phenomenon isn't limited to our planet. The European Space Agency and NASA recently released images captured by the Hubble Space Telescope of electric-blue rings lighting up Saturn's northern pole.

On Earth, auroras occur when electrons from the Sun collide with oxygen and nitrogen in the atmosphere, thus transferring some energy to the gas molecules. The gases eventually release the energy as photons, or light particles, which can take the form of colorful waves of light in the sky. This effect is amplified by the Earth's magnetic field, which is why auroras appear visible at the north and south poles where the magnetic field is strongest.

This same process plays out 746 million miles away on the ringed planet. One major difference is that Saturn's atmosphere is largely composed of hydrogen, which means its auroras are most visible in ultraviolet light. These images of Saturn's lights were taken with UV light over a seven-month period in 2017. Other gas giants in our solar system—Jupiter, Uranus, and Neptune—host their own polar light shows as well.

Astronomers observed that Saturn's northern lights peak twice during its short 11-hour day: once at dawn and once before midnight. You can view a time-lapse of the images below.

Neil Armstrong’s Spacesuit Will Go Back on Display for Apollo 11's 50th Anniversary

Neil Armstrong made history when he became the first person to walk on the Moon 50 years ago. Space exploration has changed since then, but the white space suit with the American flag patch that Armstrong wore on that first walk is still what many people think of when they picture an astronaut. Now, after sitting in storage for a decade, that iconic suit is ready to go on display, according to Smithsonian.

NASA donated Neil Armstrong's suit to the Smithsonian shortly after the Apollo 11 mission. For about 30 years, it was displayed at the National Air and Space Museum in Washington, D.C. Then, in 2006, the museum moved the artifact to storage to minimize damage.

Even away from the exhibit halls, the suit was deteriorating, and the Smithsonian knew it would need to be better preserved if it was to be shown to the public again. In 2015, the institution launched its first-ever Kickstarter campaign and raised more than $700,000 for conservation efforts.

After a multi-year preservation project, the suit will finally return to the museum floor on July 16, 2019—the date that marks 50 years since Apollo 11 launched. This time around, the suit will be displayed on a structure that was custom built to support its interior, protecting it from the weight of gravity. Climate-controlled air will flow through the gear to recreate the stable environment of a storage unit.

Even if you can't make it to the National Air and Space Museum to see Armstrong's space suit in person, soon you'll be able to appreciate it from home in a whole new way. The museum used various scanning techniques to create an intricate 3D model of the artifact. Once the scans are reconfigured for home computers, the Smithsonian's digitization team plans to make an interactive version of the digital model freely available on its website.

What Is the Kitchen Like on the International Space Station?

Clayton C. Anderson:

The International Space Station (ISS) does not really have a "kitchen" as many of us here on Earth might relate to. But, there is an area called the "galley" which serves the purpose of allowing for food preparation and consumption. I believe the term "galley" comes from the military, and it was used specifically in the space shuttle program. I guess it carried over to the ISS.

The Russian segment had the ONLY galley when I flew in 2007. There was a table for three, and the galley consisted of a water system—allowing us to hydrate our food packages (as needed) with warm (tepid) or hot (extremely) water—and a food warmer. The food warmer designed by the Russians was strictly used for their cans of food (about the size of a can of cat food in America). The U.S. developed a second food warmer (shaped like a briefcase) that we could use to heat the more "flexibly packaged" foodstuffs (packets) sent from America.

Later in the ISS lifetime, a second galley area was provided in the U.S. segment. It is positioned in Node 1 (Unity) and a table is also available there for the astronauts' dining pleasures. Apparently, it was added because of the increasing crew size experienced these days (6), to have more options. During my brief visit to ISS in 2010 (12 days or so) as a Discovery crewmember, I found the mealtimes to be much more segregated than when I spent five months on board. The Russians ate in the Russian segment. The shuttle astronauts ate in the shuttle. The U.S. ISS astronauts ate in Node 1, but often at totally different times. While we did have a combined dinner in Node 1 during STS-131 (with the Expedition 23 crew), this is one of the perceived negatives of the "multiple-galley" scenario. My long duration stint on ISS was highlighted by the fact that Fyodor Yurchikhin, Oleg Kotov, and I had every single meal together. The fellowship we—or at least I—experienced during those meals is something I will never, ever forget. We laughed, we argued, we celebrated, we mourned …, all around our zero-gravity "dinner table." Awesome stuff!
