It's Official: Uranus Smells Like Farts

Poor Uranus: After years of being the butt of many schoolyard jokes, the planet's odor lives up to the unfortunate name. According to a new study by researchers at the University of Oxford and other institutions, published in the journal Nature Astronomy, the upper layer of Uranus's atmosphere consists largely of hydrogen sulfide—the same compound that gives farts their putrid stench.

Scientists have long suspected that the clouds floating over Uranus contained hydrogen sulfide, but the compound's presence wasn't confirmed until recently. Certain gases absorb infrared light from the Sun. By analyzing the infrared light patterns in the images they captured using the Gemini North telescope in Hawaii, astronomers were able to get a clearer picture of Uranus's atmospheric composition.

On top of making farts smelly, hydrogen sulfide is also responsible for giving sewers and rotten eggs their signature stink. But the gas's presence on Uranus has value beyond making scientists giggle: It could unlock secrets about the formation of the solar system. Unlike Uranus (and most likely its fellow ice giant Neptune), the gas giants Saturn and Jupiter show no evidence of hydrogen sulfide in their upper atmospheres. Instead they contain ammonia, the same toxic compound used in some heavy-duty cleaners.

"During our solar system's formation, the balance between nitrogen and sulfur (and hence ammonia and Uranus’s newly detected hydrogen sulfide) was determined by the temperature and location of planet’s formation," research team member Leigh Fletcher, of the University of Leicester, said in a press statement. In other words, the gases in Uranus's atmosphere may be able to tell us where in the solar system the planet formed before it migrated to its current spot.

From far away, Uranus's hydrogen sulfide content marks an exciting discovery, but up close it's a silent but deadly killer. In large enough concentrations, the compound is lethal to humans. But if someone were to walk on Uranus without a spacesuit, that would be the least of their problems: The -300°F temperatures and hydrogen, helium, and methane gases at ground level would be instantly fatal.

These Rugged Steel-Toe Boots Look and Feel Like Summer Sneakers

Thanks to new, high-tech materials, our favorite shoes are lighter and more comfortable than ever. Unfortunately, one thing most sneakers are not is durable. They can’t protect your feet from the rain, let alone heavy objects. Luckily, as their name implies, Indestructible Shoes has come up with a line of steel-toe boots that look and feel like regular sneakers.

Made to be incredibly strong but still lightweight, every pair of Indestructible Shoes has steel toes, skid-proof grips, and shock-absorption technology. But they don't look clunky or bulky, which makes them suitable whether you're going to work, the gym, or a family gathering.

The Hummer is Indestructible Shoes’s most well-rounded model. It features European steel toes to protect your feet, while the durable "flymesh" material wicks moisture to keep your feet feeling fresh. The insole features 3D arch support and extra padding in the heel cup. And the outsole features additional padding that distributes weight and helps your body withstand strain.

There’s also the Xciter, Indestructible Shoes’s latest design. The company prioritized comfort for this model, with the same steel toes as the Hummer, but with additional extra-large, no-slip outsoles capable of gripping even smooth, slippery surfaces—like, say, a boat deck. The upper is made of breathable moisture-wicking flymesh to help keep your feet dry in the rain or if you're wearing them on the water.

If you want a more breathable shoe for the peak summer months, there's the Ryder. This shoe is designed to be a stylish solution to the problem of sweaty feet, thanks to a breathable mesh that maximizes airflow and minimizes sweat and odor. Meanwhile, extra padding in the midsole will keep your feet protected.

NASA Names Washington, D.C., Headquarters After ‘Hidden Figure’ Mary Jackson

In the past, NASA’s headquarters building in Washington, D.C., was simply known as “NASA Headquarters” or “Two Independence Square” (the name of that particular piece of real estate). This week, the agency officially named it the “Mary W. Jackson NASA Headquarters,” after NASA’s first Black female engineer.

Jackson worked as a math teacher and U.S. Army Secretary before NASA—called the National Advisory Committee for Aeronautics at the time—recruited her as a research mathematician for its segregated West Area Computing Unit in 1951. After completing a training program in 1958 (which she needed special permission to attend, since it took place at a whites-only high school), she was promoted to engineer.

In the following decades, Jackson studied wind tunnels and air behavior around aircraft, and she was also instrumental in helping the U.S. pull forward in the Space Race of the 1960s. But Jackson’s legacy goes beyond her own engineering efforts: Between 1979 and 1985, she participated in the Federal Women’s Program at NASA’s Langley Research Center, where she advocated for the hiring and promotion of more female scientists.

“Mary W. Jackson was part of a group of very important women who helped NASA succeed in getting American astronauts into space,” NASA administrator Jim Bridenstine said in a press release. “Mary never accepted the status quo; she helped break barriers and open opportunities for African Americans and women in the field of engineering and technology.”

Jackson died in 2005, and her story was largely unknown until the release of Margot Lee Shetterly’s 2016 book Hidden Figures and subsequent film of the same name, which chronicled the contributions of Jackson and her colleagues Katherine Johnson, Dorothy Vaughan, and Christine Darden. In 2019, Congress passed a bipartisan bill to rename the part of E Street SW where NASA’s headquarters is located to Hidden Figures Way, and the women were also awarded Congressional Gold Medals.

“We are honored that NASA continues to celebrate the legacy of our mother and grandmother Mary W. Jackson,” Jackson’s daughter Carolyn Lewis said in the press release. “She was a scientist, humanitarian, wife, mother, and trailblazer who paved the way for thousands of others to succeed, not only at NASA, but throughout this nation.”
