Physics In Vogue - Discoverer of Worlds

September 12, 2012  •  1 Comment
 

September 12, 2012:

I am happy to announce that after imaging the Venus transit and Cygnus constellation with HiMARC technology and Dr. Natalie Batalha and the Kepler Spacecraft model in the studio, the first exhibition piece for Physics In Vogue, Discoverer of Worlds, is ready! The image below features NASA's Kepler Space Telescope Mission and its method for discovering extra-solar planets by photometric transit detection.

 

Discoverer of Worlds

Discoverer of Worlds - Featuring original HiMARC imagery, Dr. Natalie Batalha and NASA's Kepler Mission

Discoverer of Worlds Description I was inspired to feature the Kepler Mission as Physics In Vogue's first piece as I know firsthand just how difficult it is to do this kind of science and thanks to a once-in-a-lifetime opportunity to image the Venus transit. It takes painstaking dedication, brilliant minds and years of precision analysis to accomplish what the Kepler team has in so short a time. You can learn about the technology I developed behind the imagery on the HiMARC page.  Check out the Get Involved page to learn how you can be a part of the extra-solar planet discovery process. Here is a color-coded breakdown of the components in Discoverer of Worlds  (see map on right): The Kepler Space Telescope is NASA's first mission capable of finding Earth-size planets around other worlds. The real spacecraft would not fit in my studio and is currently in a heliocentric orbit, so I brought in the hand-built model and overlaid it with solar cell scraps for a look like the genuine spacecraft. Discovering a planet with the transit method is a particularly low-reward science as only about 5% of star systems are in such a favorable alignment so as to have transits. To contend with this, the Kepler Space Telescope stares at an area of the sky in the Cygnus Constellation to avoid the Sun, point out of the ecliptic plane and include a large number of stars in the field of view. I captured this background of the Cygnus constellation by combining more than 8-hrs of exposure time at Humboldt State Park and used my HiMARC algorithms for processing. A bear nearly ate my dog in the process, but it turns out he was more interested in the berries. Red clouds of ionized Hydrogen gas form the emission nebulas, including the North American nebula (flipped for composition) while the Milky Way's dust lanes and stars dominate the frame. On June 5th 2012, among the rarest of predictable astrological events occurred as the planet Venus’ normal orbit brought it to pass between the Earth and the Sun.  Kepler relies on such transits to occur light-years away and though unable to view the exoplanet directly, infers its presence by a tiny dip in the amount of light coming from its hosts star. Repeat transits are needed to insure it was not a giant space bug flying in front of the lens (among other things). This year astronomers were lucky to see the transit only eight years after the previous occurrence in 2004, but the world will have to wait until 2117 to see Venus pass before the Sun again. For me and the rest of the HiMARC team, the transit provided a great opportunity to test our Atmospheric Lensing technology using a narrowband (7 nm) etalon interferometer tuned to the hydrogen alpha emission line on a 90mm refractor (this means we were able to filter out most of the light spectrum and only photograph a narrow portion in which hydrogen emits light. This allows you to see the rich textures of hydrogen on the Sun’s surface that would otherwise be obscured.) Solar features including filaments, flares, sunspots and prominences are visible. More than 1 Terabyte of data were recorded to produce this unprecedented high-resolution result! Dr. Natalie Batalha, Co-investigator on the Kepler Mission and Professor of Physics & Astronomy at San Jose State University, unassumingly brings the Vogue element to the piece and poses in the studio as I explain she should be reaching for the next new world with her right hand. As a member of the Kepler team, Dr. Batalha is responsible for the selection of the more than 150,000 stars the spacecraft monitors and works closely with team members at Ames to identify viable planet candidates from Kepler photometry. 

Final assembly, color, contrast and brightness adjustments made in Photoshop, nothing else. 48'' x 120'' framed canvas print (available in multiple formats).

Here are some shots from the production: 


Annular Solar Eclipse - Time-Lapse Panorama

May 30, 2012  •  Leave a Comment

 

Full Annular Eclipse Timelapse

 

   What’s so special about an annular solar eclipse? Unlike a total eclipse—where the Sun is eventually blocked out entirely by the moon—with an annular eclipse the moon appears slightly smaller and never fully covers the Sun, even when the two are completely aligned. Such an event usually occurs with striking visual effect: in the moment of perfect alignment the Sun looks like a glowing golden ring with a hollowed-out core.

 

Annular Eclipse Path

Ved and the HiMARC crew travelled to a park in Northern California in order to be along the path of the annular eclipse

 

   On May 20th, 2012, Ved and the HiMARC team set out for Lassen Peak in Northern California where they knew the path of the eclipse would run. By setting up their telescopic equipment on this location they could assure that their images of the event would turn out like few others’—only along this path would the solar ring surrounding the moon appear with equal thickness.

   To capture the perfect image, Ved used a hydrogen-alpha bandpass filter, through  which the details of the swirling hydrogen surface of the Sun is most visible. And for each phase of the eclipse, nine different shots were made with varying levels of exposure. By doing this, he could then digitally process the nine photographs, ultimately creating a single high dynamic range composite image. 

   You can see photographs from the HiMARC team's trip to Mt. Lassen below, as well as additional high dynamic range images of the eclipse. 

   


Uxmal, Magician's Pyramid

March 30, 2012  •  158 Comments

The Magician's Pyramid

 

   The ruins of the ancient Mayan city, Uxmal, go from impressive to unbelievable when you consider that these large stone structures were constructed without the use of wheels. It makes the myth surrounding the Pyramid of the Magician—that the structure was conjured by a dwarf over a single night—seem almost comparably plausible.  

   Today the ancient city is well preserved, though photography has been greatly limited by the Mexican government. Capturing this panoramic, high dynamic range shot of the ruins was a very unique opportunity, and no other known photograph of such resolution and quality now exists. The photograph represents a stitched composite of over 5000 shots projected on an equirectangular plane, allowing you to not only appreciate the full 360° experience, but also enjoy the many fine details of the carved stone.

Mayan Pyramid of Oxkintok

   What does the world look like from the top of the ancient Mayan pyramid of Oxkintok? Well, something like this. Thousands of images were captured and stitched together to create this stereographic projection of the full view from up top. 

 

The Pyramid at Oxkintok

 

   In the past few years, more and more ruins like Oxkintok have been discovered after centuries of being covered by thick jungle foliage. Assisted by high resolution satellite imaging, archeologists have been able to pinpoint locations where vegetation has grown up over limestone due to its slightly different coloring only discernable through multi-spectral imaging.

Mayan Ruins of Kabah, Mexico

Mayan Ruins at Kabah

   

   18 kilometers south of the more famous Uxmal, via an anciently constructed pedestrian causeway, are the ruins of Kabah. The buildings here can be easily identified as distinct among Mayan architecture for the repetition of a single pattern along the façade. These tiles of carved stone have been extremely well preserved for over 1000 years and are well documented in this high-resolution panoramic image of one of the city’s buildings.

 

Mexico Kabah Uxmal

 

   Restrictions on photographing Mayan ruins by the Mexican government have made large panoramas such as this very rare. This image is an HDR composite of over 5000 individual shots projected onto a equirectangular plane.
