Roger Hayward’s Moon (Griffith Observatory)

29 08 2012

Sculpting the moon’s surface, Griffith Observatory, 1939.

As I was sifting through images of the moon this morning, I found this photo taken at Griffith Observatory in 1939. Shown is Roger Hayward, the artist commissioned in 1934 to create a model of a section of the moon for the observatory. Hayward was trained as an architect, earning his degree from MIT before relocating to Pasadena to pursue a career as a designer. He served as chief designer for the Los Angeles Stock Exchange (1929), designed by his MIT classmate, Sam Lunden, and also contributed to Lunden’s design for the Doheny Library at USC (1930). If you recognize his name, however, I doubt it’s because you’ve been studying his architectural designs. It’s more likely you remember the illustrations he did for the “Amateur Scientist” column in Scientific American magazine between 1949 and 1974, or even more likely, the drawings he did to illustrate Linus Pauling’s research.

How does one make the leap from architect to illustrator of science? In Hayward’s case, it involved a brief stop at the moon. Moving to Pasadena worked out well for him, even though the Great Depression shut down his career as an architect almost as soon as it had begun. When the Stock Market crash put an end to large-scale design projects in southern California, Hayward kept himself busy with painting, puppetry, and physics. Pasadena sits just below Mount Wilson, so when Hayward’s interests expanded to include astronomy and mathematics, he was able to take advantage of the Caltech minds at work at the Mount Wilson Observatory. Various Caltech associates tutored him in atomic theory and he built a few smaller instruments—a 6-inch reflector telescope, a quartz spectograph—by way of educating himself in the field.

The various strands of his formal and self-education came together in 1934, when the Griffith Observatory and Planetarium commissioned him to design “the world’s largest” model of a section of the moon (more images here). As reported in The Literary Digest the next year,

“Most spectacular of the exhibits [at Griffith Observatory and Planetarium] will be in the south gallery—a thirty-eight-foot plaster model of the moon, made to scale from Mt. Wilson Observatory photographs by Roger Hayward, of Los Angeles, an architect by profession and an astronomer by preference, and Caspar Gruenfeld, a sculptor. It will be illuminated by moving lights to produce the effect of sunlight.”[1]

Hayward was given access to the 100-inch telescope on Mount Wilson so he could supplement the observatory’s photographs with first-hand observation of the moon. His design (and Gruenfeld’s sculpting work, Gruenfeld is always left out of the story) was apparently well-received, as the observatory commissioned him to design and build models of Oregon’s Crater Lake and Arizona’s Meteor Crater as soon as he finished the moon section.[2] Adler Planetarium was eager to get in on the action and hired Hayward to design a scale moon model with a 6-foot diameter. Walt Disney eventually saw the financial potential in the projects and commissioned Hayward to duplicate his moons for the “Man in Space” television show and Tomorrowland exhibits.

Although he worked in other fields after finishing the models (he designed a commercial nutcracker, for god’s sake), Hayward continued to advance his studies in astronomy and physics. He partnered with a Caltech associate to design a movie projection screen and write a physics textbook. He must have thought he’d died and gone to heaven when he was offered a position as an optical engineer at Mount Wilson Observatory in 1941. Much top secret stuff in support of the war effort ensued.

After the conclusion of the war, Hayward partnered with Sam Lunden once again, forming the firm of Lunden, Hayward & O’Connor. For architectural historians, Hayward’s story tends to end here: the firm designed the Los Angeles City Health Building, the Mira Costa High School, a VA  hospital in Arizona, the Temple Israel of Hollywood, and several other mid- to high-profile projects in the LA basin. However, although the partnership looked successful from the outside, from the inside, it was obvious that it was flawed almost as soon as the papers were signed by the trio. Hayward and O’Connor in particular didn’t get along and the partnership was dissolved in 1957.[2]

The tension between Hayward and O’Connor probably had something to do with the fact that Hayward’s attention was always directed elsewhere. Specifically, he was more concerned with his delineating work for Scientific American than he was with the success of Lunden, Hayward & O’Connor. He had completed his first job for the magazine in 1948, illustrating George Beadle’s “The Genes of Men and Molds”. The quality of Hayward’s drawings pleased the magazine, the paycheck pleased Hayward. Although he worked on many projects throughout the rest of his career—collaborating with Linus Pauling, for instance—Hayward continued to draw for Scientific American until his health and vision failed him.

The burning question of the day: what happened to the lunar section Hayward and Gruenfeld built at Griffith Observatory? Many (mistaken) bloggers attribute the moon currently on display at the observatory to the hand of Hayward, but that’s a much more recently produced object and at any rate, not a section model, but a smallish moon (there’s no way Hayward could perch on top of it and sculpt the Mare Imbrium region). According to a comment that appears to have been written by someone associated with Griffith Observatory, the Crater Lake and Meteor Crater models are in storage.[3] But where’s the lunar section? Contacting the observatory is on my list of things to do, but in two days, I’m moving halfway across the country, so that list is going to have to wait awhile. If you know, drop me an e-mail and I’ll update this with the information.

ETA: Here’s a link to a few construction photos of Griffith Observatory and Planetarium. You’re welcome.

Today’s wallpaper features a couple of my favorite things: the Paranal Observatory and a full moon. Gianluca Lombardi took this photo of one of the Auxiliary Telescopes (AT) at Paranal, using the colors of the sunset to their best advantage. Visit the ESO website to read more about light scattering, the red moon effect, and the role of the AT in the VLT Interferometer (VLTI).

NuSTAR

Bringing Black Holes Into Focus. Image credit: ESA/NASA/JPL-Caltech

While I was off doing other things in June, NASA successfully launched the Nuclear Spectroscopic Telescope Array (NuSTAR) from a carrier aircraft somewhere over the Pacific Ocean. I mention this now because earlier this week, JPL announced that NuSTAR passed its Post-Launch Assessment Review. This means that although it has been observing X-ray sources for the past few weeks, the instrument has been cleared officially to enter the “science operations phase” of its two-year mission.

Here’s mission description from the Cal Tech website:

“NuSTAR will open a new window on the Universe by being the first satellite to focus high-energy X-rays into sharp images. NuSTAR’s high-energy X-rays eyes will see with more than 100 times the sensitivity of previous missions that have operated in this part of the electromagnetic spectrum, and with 10 times better resolution. NuSTAR will shed light on some of the hottest, densest, and most energetic objects in the universe.”

Sounds cool, all that sharpness and sensitivity, but what does it all mean? What will those super sharp images tell us?

The magic words: black holes and stellar explosions.

NuSTAR’s super optics permit the observations of active galaxies with black holes at their core (much like the Fermi Large Area Telescope and the Chandra X-Ray Observatory). Some of this is just a more complex form of census taking, looking closely at the center of our own galaxy and surveying the black holes and collapsed stars.  On top of that is the added objective of mapping the composition of the youngest supernova. The hope is by identifying and locating all the materials in a supernova, we will come to a better understanding of the explosive process and how it creates the elements that make up our universe.

The third layer of the science objectives has to do with “relativistic jets.”[1] I find relativistic jets both easy and incredibly difficult to understand. On one hand, a relativistic jet is just a super intense steam of plasma (partially ionized gas) jetting out of the center of active galaxies/black holes/neutron stars. On the other hand, what the heck? You might remember the Internet buzz about this time last summer, when a black hole was observed “devouring” a star. Astronomers stumbled on that example by sheer luck: the Swift satellite was in the right place at the right time—in the path of the star’s remains in the form of a relativistic jet. It’s not so much that we don’t know these jets exist, but the theory of how they exist is still being polished by physicists. NuSTAR observations should help with that.

To keep track of NuSTAR’s discoveries, visit the News and Updates section of the mission site.

[1] If you’re wondering why they use the word “relativistic,” it’s because the particles move at almost the speed of light (0.99995c!).





Greenwich Observatory

I’ve yet to talk about my own research on this site, mostly because I’d like this to remain a ‘fun’ space, related to—but not dominated—by my real work. I’ve had an article on the relationship between Empire and the first Astronomer Royal under review for most of the past year, making me even more reluctant to write here about the Greenwich Observatory (RGO) for fear of scooping/contradicting/boring myself. But the observatory has been on my mind this week, so I decided to throw up a few photos I took during a winter visit.

Once you climb to the top of Observatory Hill (because of course you’re going to want to walk up there from Greenwich), you enter the observatory through an iron gate. To the right of the gate is the 24-hour Shepherd Clock, designed in 1852. Originally, the clock displayed astronomical time, but now it shows Greenwich Mean Time (of course). It may or may not reflect your time of arrival accurately, since it doesn’t keep track of British Summer Time. The Shepherd Clock is a slave clock, meaning that it’s controlled by a master clock elsewhere in the observatory.[1] Flamsteed would have been a lot less frustrated if the clock had existed during his tenure at the observatory. On the other hand, he had two Thomas Tompion clocks at hand, making him one of the most time-rich observers in London at the time.

If there’s one thing visitors know about the RGO, it’s that a brightly colored “time ball” drops every day at 13:00 GMT (BST in the summer). In theory, boaters on the Thames can synchronize their timepieces by the daily ball drop. In practice, boaters stopped looking to the observatory for this soon after the Great War, when the radio started providing time pips.

This unassuming patch of gravel is one of my favorite parts of the observatory. Once upon a time, this was the site of the well telescope.  For many years, the existence of a well telescope at Greenwich was a matter of debate:  did Flamsteed actually sink a shaft, install spiral stairs, and make nightly observations from the floor of the well? P.S. Laurie argued for the existence of a hole in which Flamsteed placed a telescope with a 87.5 foot focal length (seriously!).[1] In theory (again), Flamsteed used the instrument to observe gamma Draconis as it crossed the zenith, with the intent of compiling enough observations to calculate the star’s annual parallax. In practice, the well telescope was a failure. For one thing, Flamsteed had to lie on his back to use it. There’s no comfort to be found in lying on one’s back in the middle of the night at the bottom of the well. For another thing, the lens was chipped and cloudy and of little use to the astronomer.[2]

If I described all of the nifty things to see at the RGO (the time galleries, the camera obscura, the 28-inch refractor), you’d be reading this page for another several hours. You won’t be bored, and the planetarium and the Astronomy Centre have plenty of interactive exhibits to entertain the children. I’m not a child, but I spent quite a bit of time crashing imaginary spacecraft the last time I was in the Astronomy Centre. But take heed:

At the moment, the observatory is closed to the public. Why? Take a look at the view from the north side of Flamsteed House.

If you’ve been watching the 2012 Olympics, you probably recognize that Neoclassical building. The garden facade of the Queen’s House is getting quite a bit of air time, serving as a backdrop to the dressage and other equestrian events. Behind the Queen’s House and the National Maritime Museum, across the Thames, loom the Docklands. Just to the left of the Queen’s House, above the colonnade, you can see the line of the river and the embankment of the Isle of Dogs. If you cross to the Isle of Dogs and travel north past the skyscrapers (the building with the pyramidal top is the Canary Wharf Tower), across the A11, you will soon find yourself in Olympic Park.

The good news—if you’re in town for the duration of the Olympics, you need only hang on until August 4, when the RGO opens again to the public. Have a nice visit and say hello to the shell of Herschel’s telescope for me.

Astronomer’s Paradise

4 07 2012

And speaking of time lapse videos… I could have sworn I posted this one earlier this year, but I can’t find it in the archive, so maybe I made my students watch in class instead of talking about it here. “Astronomer’s Paradise” is the first of a planned three episodes in the Atacama Desert Starry Nights series. If you’d like to know more about the creation of the video or the European Southern Observatory, both National Geographic and Nikon Rumors covered the release of the video back in February.

Visnjan observatory timelapse teaser from Romulic & Stojcic on Vimeo.

As far as I know, Romulic and Stojcic have yet to release the full version of this time lapse of Višnjan Observatory in Istria, Croatia. The two minutes and thirty-six seconds that they did release is pretty sweet, though.
