“Dr Heisenberg’s Magic Mirror of Uncertainty” is the name of a series of photographs taken in 1999 by the American photographer Duane Michals. The picture over at that link is lovely, but I don’t really see the connection to quantum mechanics. I suspect my artist friends would accuse me of being a scientific literalist, which doesn’t bother me one bit.
More to my liking are the graphics pictured above, which have been created by Ariel Waldman and Lisa Ballard. The pair run a website called spaceprob.es, which “catalogues the active human-made machines that freckle our solar system and dot our galaxy”. Here is their page on Voyager 2, which is packed with facts about the mission’s instruments and many accomplishments. These and other illustrations of space missions can be bought as stickers and posters – the perfect gift for the space enthusiast in your life.

After two days of getting to grips with biophysics – see here and here for my experiences – I was ready for a change of scene. And a visit to the Space Telescope Science Institute (STScI), co-located with the Johns Hopkins University in Baltimore but operated on behalf of NASA, was just what I needed.
The STScI is home to many of the scientists and engineers who made the Hubble Space Telescope possible, and who have been working for many years to design the optics and instrumentation for its successor – the James Webb Space Telescope (JWST), which is due to be launched in 2018. The institute also runs the science operations for Hubble and soon will for the JWST, providing software tools for astronomers to make their observations and processing the raw data acquired by the onboard instruments to make it ready for scientific analysis.

Giving a fired-up talk at a physics conference is a good way for aspiring researchers to make themselves known to the community, but unless you have a natural gift, lots of practice is required. That’s why many universities and labs host “slams” to encourage staff and students to talk about their research to a broader audience. Above is a video of the sold-out Fermilab Physics Slam 2014, which was held last week at the lab on the outskirts of Chicago.

Whatever punters make of the Manchester International Festival (MIF) next year, they certainly won’t be able to accuse it of thinking small. Among the first commissions announced today is a “world-first show about the origin of the universe and everything within and without it”.
The Age of Starlight will be presented by the physicist and TV personality Brian Cox, who will tell the story of the unlikely events that have led to our existence. Details of the show are still scarce but we do know that the space bonanza will feature computer-generated imagery created by the Oscar-winner Tim Webber and the special-effects team behind the film Gravity. The event will be brought to life with technologies developed by Magic Leap, a Florida-based IT company that specializes in “magical” computing solutions.

Besides the great views of the Earth, one of the best things about being on the International Space Station (ISS) must be messing around in near-zero gravity. In the above video on Science Friday the American astronaut Don Pettit describes an “experiment” that he did on the ISS using candy corn, which are kernel-like sweets. He begins with a blob of floating water into which he inserts the candy corn pointy-end first. The points are hydrophilic so they tend to stay in the water, and eventually Pettit has a sphere of candy corn packed around the water. The flat ends of the candy corn have been soaked in oil to make them hydrophobic so the candy corn layer acts like a detergent film or one half of a cell membrane. It’s a fun video and I wonder how he got the idea in the first place?

With space agencies across the world planning manned missions to Mars in the coming decades, pondering what one would eat while on Mars seems like a sensible thing to do. SpaceX engineer Andrew Rader helps us out with this difficult question in the video above, sharing gems like “chickens can’t swallow in space.” In the video, titled “Cooking on Mars” Rader cooks and eats a seemingly unappetizing option – bugs and insects – and makes it clear that is the fare future astronauts will be partaking in.

Has the Voyager spacecraft left the solar system and entered interstellar space? I don’t know about you, but I’m getting a teensy weensy bit bored by this question, which has been going on for years now.
Previous to that, though, there had been other reports that no it hadn’t (June 2013), it really, definitely is getting near the edge, but hang on actually not yet (March 2013), we’re not quite sure (June 2011), of course it’s definitely heading for interstellar space (November 2009), it’s already right near the edge (or possibly not) (November 2003).

“I wanted to make a film about an old space cowboy” is how British director Mark Craig introduced his new film on Sunday afternoon here at Sheffield Doc/Fest. The Last Man on the Moon takes a fresh look at the the Apollo era through the story of Eugene Cernan, who was the last person to set foot on the lunar surface when he did so in 1972 as commander of Apollo 17.
The documentary interleaves a profile of “Gene” Cernan with NASA archive footage and special effects, focusing on the personal stories of the astronauts and their families. To give you a flavour, the film opens in the present day with close-ups of Cernan’s facial reactions at a rodeo event as he admires the spectacle and the bravery of the men being thrown around on the back of bulls. Later in the film, Cernan recounts his experiences of being rotated rapidly in space during the Gemini 9A and Apollo 10 missions.
Immediately after the showing, Cernan and Craig stayed for a Q&A session and the audience gave an extended standing ovation as the 80-year-old astronaut walked to the front of the auditorium. I was fortunate to catch up with the pair this morning to get some insights into the inspiration for the film and how it was adapted from the book Cernan co-authored in 1999.

While you would not actually be able to hear the uplifting notes of the music in the vast emptiness of space, a newly composed string and piano orchestral piece has unexpected ties to the cosmos. That’s because it is based on 36 years’ worth of data from NASA’s Voyager 1 and 2 spacecraft. Domenico Vicinanza, a trained musician with a PhD in physics who works at GÉANT, a European data-network company, says that he “wanted to compose a musical piece celebrating Voyager 1 and 2 together, so I used the same measurements (proton counts from the cosmic-ray detector over the last 37 years) from both spacecrafts, at the exactly same point in time, but at several billions of kilometres of distance [of] one from the other”. The result of this “data sonification” is a rather beautiful piece of music – one of the best examples of physics and the arts coming together that we have heard. Of course, the story garnered considerable interest…you can read more about on the Wired and Guardian websites.

Early this week, a story in the Telegraph caught our eye – NASA is planning on sending turnip, cress and basil seeds to the Moon to germinate them! This is most definitely not the first time that plants have been grown beyond the realms of Earth. Indeed, potatoes were grown on board during a 1995 Space Shuttle mission and many experiments involving germinating seeds were done on the International Space Station. The goal of these studies was to understand the effects of microgravity on plant growth. But now, NASA plans to take this one step further in 2015 with their Moon Express mission, which will include the Lunar Plant Growth Chamber that will carry seeds and enough air and nutrients to allow the seeds to sprout and grow. Will fresh salad be on an astronaut’s menu soon?
