Thanks to Susan Buchanan over @NYAS for all of the listings this week. I got these choice events from New York Science Academy’s Science and the City email.
Science Performance
Terra Nova: Sinfonia AntarcticaListen to the sounds of glaciers melting at this multimedia performance by Paul D. Miller (DJ Spooky) that’s co-presented with the Margaret Mead Film & Video Festival this month. (continue reading…)

Nasa's Image of the Day
Little Galaxy With a Tail
This infrared portrait of the Small Magellanic Cloud, taken by NASA's Spitzer Space Telescope, reveals stars and dust in this galaxy as never seen before. T The image shows the main body of the Small Magellanic Cloud, which is comprised of the "bar" and "wing" on the left and the "tail" extending to the right. The bar contains both old stars (in blue) and young stars lighting up their natal dust (green/red). The wing mainly contains young stars. The tail contains only gas, dust and newly formed stars. Spitzer data has confirmed that the tail region was recently torn off the main body of the galaxy. Two of the tail clusters, which are still embedded in their birth clouds, can be seen as red dots. The data in this image are being used by astronomers to study the lifecycle of dust in the entire galaxy: from the formation in stellar atmospheres, to the reservoir containing the present day interstellar medium, and the dust consumed in forming new stars. The dust being formed in old, evolved stars (blue stars with a red tinge) is measured using mid-infrared wavelengths. The present day interstellar dust is weighed by measuring the intensity and color of emission at longer infrared wavelengths. The rate at which the raw material is being consumed is determined by studying ionized gas regions and the younger stars (yellow/red extended regions). The Small Magellanic Cloud, and its companion galaxy the Large Magellanic Cloud, are the two galaxies where this type of study is possible. Image Credit: NASA/JPL-Caltech/STScI
