“For the first time, an instrument onboard an orbiting spacecraft has measured the methane emissions from a single, specific leaking facility on Earth's surface,” NASA announced Tuesday.
Hey Jupiter, I hope you're ready for your close-up.
Recently, I was granted the rare privilege of stepping inside one of the largest cleanrooms at NASA's Jet Propulsion Laboratories. I was there to learn about this year's blockbuster space mission, Juno, and chat with some super smart science and engineering people who worked on the project.
In my weekly segment on KCRW's “Press Play” news program with host Madeleine Brand, we listen to Elon Musk wax poetic about artificial intelligence and whether life might be a dream--and his plans to send humans to Mars by 2025.
New analysis of the dagger buried with King Tut confirms that the weapon was made from an iron meteorite. They used X-ray fluorescence spectrometry to study the dagger, found on Tut's mummified body by Howard Carter in 1925. Daniela Comelli of Milan Polytechnic's department of physics and her colleagues have even identified the most likely meteorite used to forge the dagger.
"We took into consideration all meteorites found within an area of 2,000 km in radius centered in the Red Sea, and we ended up with 20 iron meteorites," Comelli told Space.com. "Only one, named Kharga, turned out to have nickel and cobalt contents which are possibly consistent with the composition of the blade."
The study shows the ancient Egyptians attributed great value to meteoritic iron for the production of precious objects, possibly perceiving those chunks of iron falling from the sky as a divine message.
The most ancient Egyptian iron artifacts, nine small beads excavated from a cemetery along the west bank of the Nile tomb in Gerzeh and dated about 3200 BC, are also made from meteoritic iron hammered into thin sheets.
"It would be very interesting to analyze more pre-Iron Age artifacts, such as other iron objects found in King Tut's tomb. We could gain precious insights into metal working technologies in ancient Egypt and the Mediterranean," Comelli said.
The massive wildfire that continues to burn in the Fort McMurray area of Alberta, Canada has been captured from space by NASA imaging satellites.
For amateur astronomers, tonight is an exciting night.
I'm ashamed to admit that I never learned much about the International Space Station. But after seeing the IMAX 3D documentary A Beautiful Planet, I feel like I spent 45 minutes in it, and it was emotional and thrilling. I'm normally not a big fan of 3D movies, but the quality was so high that it didn't bother me and instead made the experience of learning about life inside the ISS that much better.
I was enthralled the entire time I watched the movie. I felt like I was floating in the ISS, observing the astronauts right in front of me as they ate, cut their hair, made espresso, helped each other get into their spacesuits, and played the bagpipes. I remember reading somewhere that one of the requirements of being an astronaut is that you can't be arrogant or have a big ego because those aren't good traits to have when you live in close quarters for months on end with other people. The astronauts on the ISS all seemed very smart, good natured, and kind. I wanted to hug them all.
The movie, which is narrated by Jennifer Lawrence, is called A Beautiful Planet because the main star of the show is our planet as filmed by crew of the ISS. We've all seen images of the Earth from space, but to see them in 3D on giant screen in crystal clarity is another experience altogether. My 13-year-old daughter was shocked by the nighttime footage of South and North Korea. Read the rest
The European Organization for Nuclear Research, or CERN, has been releasing portions of its research to the public for years. This week's massive 300 terabyte dump of Large Hadron Collider (LHC) data is the biggest yet by a long shot -- and it's all out there, open source, free for the exploration.
Ariel Waldman, creator of Spacehack, has just published a delightful book titled "What's It Like in Space? Stories from Astronauts Who've Been There?" Illustrated by Brian Standeford, it's a fun collection of astronaut anecdotes on everything from sneezing and farting in zero gravity to weird frights and the necessity of Sriracha in space. Here's an excerpt:
The early male astronauts often had leaky space suits. They would frequently complain about their urine leaking into other areas of the suit. For a while, no one could figure out what was wrong with the spacesuits. NASA eventually realized the leaking was due to the oversized condom catheters the astronauts were using. Turns out that when the astronauts were asked by doctors what size they needed, they would often ask for “large.”
"Today, we commit to this next great leap into the cosmos," Stephen Hawking said today in New York. "Because we are human, and our nature is to fly."
Baker/cookbook author Heather Baird was so inspired by a book of photos from the Hubble space telescope that she created a "Black Velvet Nebula Cake" that is studded with edible white confetti sprinkles to create a starscape that shoots right through the whole cross-section, while the surface is intricately painted with gorgeous nebulae made from tinted edible gels.

While performing a spacewalk is an exciting experience, it is also a very serious operation that is meticulously scripted for astronauts. The only time astronauts might get a chance to look around at where they are is when there’s a glitch in equipment and they get a few spare minutes while someone makes a repair. Astronaut Chris Hadfield found an opportunity to look around during one of his spacewalks:
“The contrast of your body and your mind inside . . . essentially a one-person spaceship, which is your space suit, where you’re holding on for dear life to the shuttle or the station with one hand, and you are inexplicably in between what is just a pouring glory of the world roaring by, silently next to you—just the kaleidoscope of it, it takes up your whole mind. It’s like the most beautiful thing you’ve ever seen just screaming at you on the right side, and when you look left, it’s the whole bottomless black of the universe and it goes in all directions. It’s like a huge yawning endlessness on your left side and you’re in between those two things and trying to rationalize it to yourself and trying to get some work done.”
