Sloan Digital Sky Survey Extended to Second Run
This image of the galaxy NGC 6070, which is more than 100 million light years away, was taken during the Sloan Digital Sky Survey's first run.
Over the past five years, the Sloan Digital Sky Survey mapped one quarter of the nighttime sky, identifying more than 100 million stars, galaxies and quasars. Now, with additional funding from the NSF, the Alfred P. Sloan Foundation, and participating institutions, the survey will continue through mid-2008, expanding its horizons to study the expansion of the universe and the formation of galaxies.

"This fundamental science will allow us to continue testing cosmological models," said SDSS director Rich Kron, of Fermilab and the University of Chicago.

The extension, which officially began on July 1, has three purposes. The first is to continue mapping the skies to create an even larger, contiguous chart of the heavens. The survey's first run mapped over 7,000 square degrees of the sky in two oval-shaped regions; the second run will fill in the gap between these two areas, creating one large map.

In its second goal, the survey will scan the sky for supernovae to help measure dark energy. By tracking the brightness of supernovae over time, researchers will be able to accurately measure the rate at which the universe expands. Because this expansion is propelled by dark energy, the survey will help quantify the characteristics of dark energy in the universe.

The survey's third and final purpose is to measure the amount of dark matter in the Milky Way. Stars in the outer parts of our Milky Way are observed to travel faster than can be explained by the gravitational pull of other luminous stars alone, suggesting that dark matter also propels their movement. "Along with dark energy, this is the biggest challenge for astrophysics right now," said Fermilab scientist Brian Yanny. By measuring the speeds of these stars, the Sloan Extension for Galactic Understanding and Exploration (SEGUE) will attempt to quantify the amount and distribution of dark matter in our galaxy.

"These three goals make for a very ambitious project," said Steven Kent, the head of survey operations at Sloan and the head of Fermilab's Experimental Astrophysics Group. "We're taking not just one leap forward, but two."

Artists and scientists conspire at conference
Cartoons and morphing software may help to convey scientists' finds.
by Philip Ball
"We must do this more often" was the constant refrain at a gathering of scientists, artists, film makers, designers, writers, editors and art historians at a meeting in Los Angeles. They were there to explore the use of images in science, for both understanding data and communicating it to others.

Image and Meaning 2, held from 23 to 25 June at the Getty art museum, was the successor to the first conference of this sort, staged in 2001 at the Massachusetts Institute of Technology (MIT) in Boston.

Safety Tip
ES&H Concern?
Fermilab's management has set high standards for ES&H performance. One key to success is the prompt resolution of ES&H concerns that are identified by the people who work here. In most cases, such matters can be satisfactorily addressed through interactions at the work-group level - co-workers and supervisors.
"Out of this nettle,
danger, we pluck
this flower, safety."
William Shakespeare
(1564-1616), from
King Henry the Fourth,
Part I.
Sometimes, though, the involvement of ES&H professionals, or people further up the management chain, may be needed to get issues resolved.

Less often, these standard approaches can be ineffective or unusable. For example, the process may simply fail to address the concern, or the identity of the organization that owns the concern may be unclear, or the observer may fear retribution for reporting the concern. Fortunately, there is an electronic reporting system that helps avoid these problems.

Go to the ES&H Section's website and click on the Quick Link labeled Report ES&H Concern. From there you will be given a choice of Safety Concern or Suggestion Box. Click on the Safety Concern link if you are willing to identify yourself. This is the preferred approach. If your identity is known, it makes it easier to understand the issue and make sure the results are reported back to you. By default, the message is routed to your Senior Safety Officer, though you can select another SSO if that seems appropriate.

Alternatively, you can click on the Suggestion Box link if you wish to remain anonymous. Fermilab's management does not want any ES&H issue to go unaddressed for fear of retribution or embarrassment.

Have a great day and let's work safely all week!
