And the music is enjoyable, too. In this video, the music is written in quadruple meter, moves delicately into eight measures of triple meter, returning to quadruple again. The waltz meter is heard twice during the play of the video. Nice and unexpected .

Since the Solar Dynamics Observatory opened its multi-spectral eyes in space about three years ago, we’ve posted numerous videos and images from the mission, showing incredible views of our dynamic Sun. Scott Wiessinger from Goddard Space Flight Center’s Space Visualization Studio has put together great timelapse compilation of images from the past three years, as well as a one composite still image to “try to encapsulate a timelapse into one static graphic,” he told us via email. “I blended 25 stills from over the last year, and it’s interesting to see the bright bands of active regions.” Scott said he was fascinated by seeing the views of the Sun over a long range of time.

Within the video, (below) there are some great Easter egg hunts – things to see like partial eclipses, flares, comet Lovejoy, and the transit of Venus.

How many can you find?



SDO’s Atmospheric Imaging Assembly (AIA) captures a shot of the sun every 12 seconds in 10 different wavelengths, but the images shown here are based on a wavelength of 171 Angstroms, which is in the extreme ultraviolet range. It shows solar material at around 600,000 Kelvin. In this wavelength it is easy to see the Sun’s 25-day rotation as well as how solar activity has increased over three years as the Sun’s solar cycle has ramped up towards the peak of activity in its 11-year cycle.

You’ll also notice that during the course of the video, the Sun subtly increases and decreases in apparent size. This is because the distance between the SDO spacecraft and the Sun varies over time. The image is, however, remarkably consistent and stable despite the fact that SDO orbits the Earth at 6,876 miles per hour and the Earth orbits the sun at 67,062 miles per hour.

See more views, wavelengths and information at this page at the Space Visualization Studio website.

Correction. In the video's soundtrack, the waltz or triple meter is heard not twice but four times: 1) 8 meausres; 2) 24 measures; 3) 8 measures; 4) 15 measures to fade.

Bright Meteor Rocks Argentina Rock Concert
Universe Today, Nancy Atkinson | April 23, 2013

Talk about a light show! A massive bolide was captured on video during a middle-of-the-night rock concert in Argentina on April 21, 2013. The band, Los Tekis performed at an outdoor concert venue and in perfect timing, right after the band concluded a song, the person who shot the video panned out so that the sky was visible — just as the bolide lit up the sky.

News reports say the bright fireball was not only seen in Salta, Argentina, the location of the Zamba Festival, but was seen widely across Santiago del Estero, Corrientes, Córdoba, Chaco and in other locations, even though it was about 3:20 am local time.

The band’s website quotes Matías Díaz, who filmed the event as saying, “People demanded an encore of the Tekis, then they returned to the stage and was at that moment when the sound was cut and decorated the right side was a large green light falling from the sky. People at first did not know it was, thought someone had thrown a vengala but then began to speak of a meteorite.”

Illustration (The Finest Occupation)
Maria Popova, Brain Pickings dot org

A charming tongue-in-cheek testament to the art of taking joy in one’s work.

I recently had the delight of moderating an AIGA conversation on the future of illustration with all-star illustrators Christoph Niemann, Nicholas Blechman, and Jennifer Daniel, in which two things became immediately clear: The borders of what illustration actually is are ever-shifting, and the finest illustrators take enormous pride and pleasure in their work, despite its creative frustrations.

From Temujin Doran — documentarian, illustrator, language-lover, provocateur — comes Illustration (The Finest Occupation), a lovely short film about illustration based on a poem he wrote in his last year of (illustration) school, “a fictitious congratulatory letter written by a proud tutor to a recent graduate.” Doran’s drawings reminiscent of Edward Gorey and tongue-in-cheek rhymes, despite their irreverent tone, deliver the same tremendously important message Ray Bradbury so passionately articulated: Work with joy, always.

This Week in Science and Technology is back! Sponsored by ScienceAlert, the weekly sci-tech news wrapup I do with my friend and biologist, Dr. Carin Bondar, was on hiatus for a while, but we’re back and covering the latest events.

In this week’s TWiST: the epigenetics of anorexia, a mother’s touch, and (me talking about) Comet ISON.


^ Go to YouTube to see this in
higher resolution. ISON is a weird little iceball. It showed a lot of activity early on, but then in the time between my filming this segment and it getting online, I heard the comet seems to have slowed its brightening a bit. By itself, that doesn’t mean much. Comets are notoriously unpredictable when it comes to activity and brightness. It could be that the comet has run out of ice for now, so it’s not getting brighter. Or it could be the brightening we saw earlier was anomalous, due to a big pocket of ice getting loose, sublimating (turning directly from a solid into a gas), and expanding. As the comet gets near the Sun, another one could let go, or maybe not much will happen at all. It’s maddening, but comets are fickle prey for astronomers. Like I say in the video, we’ll just have to see.

Also, we had some audio issues in the past couple of TWiSTs, and hopefully those are being resolved. I’m shopping for a new microphone now, in fact. I have a new camera (a Canon Rebel T4i, if you care) that I like quite a bit, but I’m still learning how to use. Bear with me! And see you next week in a new episode of TWiST.

The Sun Burps Out a Gigantic Rolling Wave
Universe Today, Nancy Atkinson | May 1, 2013

Just in time for May Day, the Sun blasted out a coronal mass ejection (CME) from just around the limb earlier today, May 1, 2013. In a gigantic rolling wave, this CME shot out about a billion tons of particles into space, traveling at over a million miles per hour. This CME is not headed toward Earth. The video, taken in extreme ultraviolet light by NASA’s Solar Dynamics Observatory (SDO), covers about two and a half hours of elapsed time.

Camilla, the rubber chicken mascot for the SDO, said via YouTube that getting this side view shows the power and force behind these solar flares and coronal mass ejections.

This image shows three views of the CME from three different instruments. Left is the SDO image, taken at 02:40 UT. Center is from the SOHO spacecraft, looking through their coronograph instrument. The “mushroom” cloud of plasma leaving the Sun is visible. On the right is the LASCO C2 (red) and C3 (blue) instruments on SOHO, which use a disk to block out the Sun. Visible are the solid occulter disk, used to create a false eclipse; the “pylon”, which is an arm that holds the occulter disk in place; a representation of the Sun in the form of a white disk drawn on the occulter during our image processing and then you can see background stars and the cloud of plasma leaving the Sun.

Blue Flower/Flor Azul Permanent public art piece for George Pearl Hall School of Architecture and Urban Planning at University of New Mexico.
from federico muelas; 1 month ago

VIMEO NOTES. In 2008 New Mexico Arts State agency commissioned artist Federico Muelas to create a permanent Public Art installation for the George Pearl Hall building at the University of new Mexico, which houses the New School of architecture and urban planning.

The selecting committee, formed by school dean Roger Schluntz, UNM faculty, city council members, NMA representatives, New Mexico artists and AIA architects Antoine Predock, Graham Hogan and Jon Anderson asked Federico Muelas to create a piece for the building based on his most recent body of work, that focuses on complex natural systems.

For this project Federico Muelas designed an Art piece titled “Blue Flower/Flor Azul” that displays the image of drops of blue ink expanding in clear water on a 900 sq. foot custom made LCD screen.

A team of 30 people, including electronic and structural engineers, programmers, electricians, fabricators and volunteers worked for four years under the direction of Mr. Muelas to design, implement, fabricate and install the piece that enlivens, since September 2012, the west side facade of the building.

For this piece Federico Muelas studio fully implemented a brand new technology for large format displays based on Electro-responsive LCD film.

The 30 by 30 feet display is powered with a maximum of 9 amps, approximately the energy consumed by two and a half computers, what positions “Blue Flower” screen among the most energy efficient large format displays in the world and it is 34 times more efficient than any LED Screen in the market and at a fraction of the production cost. As requested by the commission the display obtained its UL label in 2012.

During the day the screen renders a low-resolution image of the ink via the 3,740 pixels distributed in a 70 by 70 grid that forms the circular screen. Each pixel is 5” diameter in size, being the largest single pixel ever used in a large format LCD display.

When each pixel is inactive it appears white, when turned ON, the pixel becomes a perfect reflective surface that projects whatever is in front. For example the Sky, the landscape, or the George Pearl Hall building itself. Therefore the aspect of the rendered image on the screen varies with the location of the viewer as well as with the appearance of the surroundings.

At dusk the LCD screen turns OFF becoming a blank projecting surface in which two 12,000 lumens Sanyo projectors, located on the outdoor amphitheater, broadcast the image of the ink in high definition.

“Blue Flower” also incorporates a sound element as the moving image of the ink is translated into sound in real time and locally broadcast on the site.

To accomplish the sound translation of the moving image of the ink an embedded computer lays out a matrix of sensitive nodes over the source image before it is sent to the LCD display or to the projectors.

Each node gets assigned a unique note that creates a sound when the image of the ink passes over its location.

“Blue Flower/Flor Azul” attempts to create an “Imagination screen” for the University community and the visitor and to build a physical and virtual common place to share ideas and nurture dreams. It also tries to recreate the unadulterated pleasure of learning by merely experimenting with the mysterious processes of nature consequently promoting awareness, understanding and stewardship in relation to the natural world.

“I want to create in the observer an alternating range of rational reflections and spontaneous emotions including the feeling of comprehending the indecipherable and making the invisible visible.” Federico Muelas
