A new exhibition connecting art and science opens May 12th outdoors in the garden of the John Nicholas Brown Center at Brown University in Providence, RI. The exhibition features X-ray images of the cosmos from NASA’s orbiting Chandra X-ray Observatory, X-ray images of paintings from the Harvard Art Museum, as well as pieces by artist Roxanne Crocker of the Rhode Island School of Design. Entitled "Sight Lines: Looking Back, Seeing Through," the exhibition is free and open to the public during daylight hours from May 12 through May 31, 2010.
Scientists have used NASA's Chandra X-ray Observatory and ESA's XMM-Newton to detect a vast reservoir of gas lying along a wall-shaped structure of galaxies about 400 million light years from Earth. In this artist's impression, a close-up view of the so-called Sculptor Wall is depicted. Spiral and elliptical galaxies are shown in the wall along with the newly detected intergalactic gas, part of the so-called Warm Hot Intergalactic Medium (WHIM), shown in blue. This discovery is the strongest evidence yet that the "missing matter" in the nearby Universe is located in an enormous web of hot, diffuse gas.
For those of you who are still making 4th of July plans and might be in Washington, DC, for the holiday, here's something to consider. There will be a Chandra exhibit at this summer’s Smithsonian Folklife Festival from July 3-5. Why, you might ask?
This composite image of the nearby starburst galaxy M82 shows Chandra X-ray Observatory data in blue, optical data from the Hubble Space Telescope in green and orange, and infrared data from the Spitzer Space Telescope in red. The pullout is a Chandra image that shows the central region of the galaxy and contains two bright X-ray sources -- identified in a labeled version, roll your mouse over the image to view -- of special interest.
Maybe it's the large number of the pre-school people that we spend time with these days, but we see shapes all over the place. Hoping to go beyond the snack-and-nap crowd, we like to look for similar shapes in very unexpected places.

Since the dawn of the Internet, there have been countless things that have come and gone. To some of them, we can easily say good riddance (flashing rainbow icons? the used-to-death phrase of the "information superhighway"?)
In other words, not many vestiges of the Internet circa 1996 remain, but one important one does: the Webby awards. Presented by the International Academy of Digital Arts and Sciences, the Webbies are still one of the most prestigious digital awards around.
Two different teams have reported using Chandra observations of galaxy clusters to study the properties of gravity on cosmic scales and test Einstein's theory of General Relativity. Such studies are crucial for understanding the evolution of the universe, both in the past and the future, and for probing the nature of dark energy, one of the biggest mysteries in science.
A new image from NASA's Chandra X-ray Observatory and Spitzer Space Telescope shows the dusty remains of a collapsed star. The dust is flying past and engulfing a nearby family of stars. Scientists think the stars in the image are part of a stellar cluster in which the a supernova exploded. The material ejected in the explosion is now blowing past these stars at high velocities.
Richard Dawkins, the Oxford zoologist and author, once said that "science is the poetry of reality", an observation that inspired a new video from the people who run the Symphony of Science project.
Another link can be made between science and poetry when scientific discoveries inspire people to write poems. Jonathan Taylor, a Senior Lecturer in Creative Writing at De Montfort University in the UK, wrote a poem about the deep note generated by a black hole in the Perseus galaxy cluster.
