Is Anybody Out There? Spitzer Explores the Universe to Understand Planet Formation

NASA’s Spitzer Space Telescope is exploring the universe using infrared light which reveals the composition of objects within the solar system as well as detecting the material that may be forming worlds around other stars.

Launched in August 2003, the fi rst Spitzer images have arrived and are being analyzed by University researchers. Among them are graduate student Michael Kelley, Prof. Chick Woodward and Prof. Bob Gehrz. By studying the images and spectra of comets and their dust trails, they will be able to better understand how planets form. Comets are key to understanding how the universe developed because they represent the original material that formed planets.

Chick Woodward compared this to making bread. “There is a lot of material that is left over and didn’t get into the loaf. You bake the bread and change its appearance. But you put the leftovers in the freezer and it remains unchanged. Comets are the frozen leftovers.” Spitzer continued on p. 5

THANKS! Often, in the fl urry of com-puter and budget crashes, endless proposal writ-ing and confusing research results, we forget how wonder-ful it is, and how privileged we are to

be engaged in exploring the mysteries of the universe. And we can do this because you, as taxpayers and as supporters of our Department, make it possible. So I hope you enjoy this little newsletter to talk about the wonderful things we’re discovering, and a bit about the people engaged in this adventure.

This year we saw Spirit and Opportunity scoot around Mars, fi nding more and more evidence that liquid water was once plentiful on its surface. And the Cassini mission to Saturn treated us to spectacular new looks at the rings, and the fi rst ever pictures of the surface of Titan from the Huygens probe.

Minnesota astronomers have been pushing back the frontiers on all scales. In our own solar system, observations with the new Spitzer infrared telescope showed the con-nections between dust in the Hale-Bopp

First Light LBT Update

Construction continues full steam ahead on the Large Binocular Telescope (LBT) on Mt. Graham’s Emerald Peak in Arizona. The fi rst engineering test images from a single mirror have been obtained, and the offi cial “fi rst light”, signifying the LBT’s readiness for scientifi c studies, should occur next year. On October 15, 2004, the Telescope Dedication was held in Tucson, followed by a tour of the LBT the next day. Representing the University’s partnership in this effort were Len Kuhi and E.

Thomas Sullivan, the U’s new Senior Vice President and Provost.

This last year presented many challenges for the telescope construction crew. Moving the fi rst primary mirror and its bell jar aluminizing enclosure up the steep and narrow road of Mt. Graham was a harrowing experience that took several days. To the delight of everyone involved, the fi rst mirror was inserted into its cell on March 16, 2004 and then integrated with the telescope structure shortly thereafter. After polishing, the

second mirror will repeat the trek up the mountain in September, 2005. In between, the site was threatened by the Nuttall Complex Fire, (see www.fi reteam-sw.com/oltrogge/incidents/nuttall) but thanks to the diligent work of fi refi ghters and observatory staff, neither the enclosure nor telescope were damaged. Almost-live views of telescope construction are available at: abell.as.arizona.edu/~hill/latesth.cgi .

The Astronomy Department continues to need signifi cant capital and operating funds to secure our partnership in this exciting project, and to match the Hubbard challenge grant. We are extremely grateful for the gifts and support we have received so far, and we look forward to “First Light” and the advances that this telescope will bring to the Department and to everyone’s knowledge about this wondrous universe.

In the Dark Liliya L.R. Williams

Though protons, neutrons and electrons make up only about 3 percent of the total mass-energy content of the Universe, most astronomers study only these particles, paying little attention to the dark sector, which accounts for the remaining 97 percent. In a desperate attempt to correct this highly skewed situation, I have focused on topics in astronomy which have the word “dark” in their names. I concentrate mostly on dark matter and its detailed distribution in galaxies and clusters of galaxies.

Eric Barnes, research associate and Crystal Austin, graduate student and I approach these studies by performing calculations about the behavior of dark matter using fundamental physical laws. We have spent the last year generating and analyzing galaxy-sized dark matter halos using an “analytical” technique which still often involves complex calculations on the computer. These calculations will help us understand the dark matter halos of real galaxies, especially dwarf galaxies and those of low surface brightness. Other researchers use what are called “N-body” simulations on the computer, where they watch the behavior of large groups of dark matter particles as they form into galaxy halos. We use our own calculations to explore the physical processes driving the evolution of these computer simulated halos.

Another project of mine is to analyze images of real galaxies and clusters of galaxies whose light has been distorted by intervening dark matter (gravitational “lenses”, see fi gure). This analysis allows me to reconstruct the detailed distribution of the dark matter, even though it cannot be seen. The method I am developing allows me to study even small, very faint features within galaxies, such as the dark matter gravitational forces associated with bars, spiral arms, and satellite dwarf galaxies. Results of this work will be used to test cosmological models, study the dynamics of galaxies, and place constraints on the properties of dark matter.

comet and dusty disks around other stars that have not yet formed planetary systems. And across the universe, distortions in the light of distant galaxies have enabled us to map out the invisible ‘dark matter’, whose nature is still a mystery. Please explore around our web site (www.astro.umn.edu) to see all the exciting things going on.

This year Chair Len Kuhi retired after a long and distinguished career as a scholar, teacher and administrator. His latest achievement was establishing a partnership with the Large Binocular Telescope project in Arizona, through the generous challenge grant by Stan Hubbard. Many challenges remain in solidifying this partnership through matching endowment funds and dealing with the dramatic cuts in the University’s state funding. But our thoughts continue to soar high, and with your support, we’ll continue to bring the wonders of the Universe down to Earth! Lawrence Rudnick

Freshman Seminars

Since the initiation of freshman seminars in 1998, the Astronomy Department offerings have been very popular with students. The seminars offer close contact between freshmen and faculty, a sense of belonging among students and valuable mentoring opportunities. As communication-intensive experiences that emphasize speaking, writing, and critical thinking, the seminars provide skills central to learning at any level and excellent preparation for advanced courses. Here are some of the seminars that we have offered:

ET Call Home: The Search for Len KuhiExtraterrestrial Intelligence

This seminar reviews the history of searches for extraterrestrial intelligence, and discusses the astronomical background necessary to understand those searches, e.g., planetary formation, conditions for life, NASA exploration of the planets in our solar system, discovery of planets around other stars, odds for fi nding life elsewhere in our galaxy, diffi culties of space travel, present-day searches and successful searches based on the SETI Project. Students also read the book "Contact" by Carl Sagan and take a critical look at popular ET mythology such as prehistoric contacts, crop circles and UFOs.

Cosmic Impacts: Scars on the Earth Terry Jones

Particpants in this seminar explore the dangerous world of our solar system and discuss the answers to the following questions: What happens when a large object smashes into the Earth? Did a comet or asteroid kill off the dinorsaurs? What would happen to humanity in such a calamity?

Nothing Larry Rudnick

Just imagine a class where you study “nothing”! It doesn’t take much probing to realize that “nothing” is just about the richest source of ideas about how we and the Universe work. In this course, we study the nature of the vacuum (it’s not possible!), the intriguing history of the number zero, and the emergence of the entire universe out of nothing. Guest lecturers explore with the students the use of empty space in design, placebos as medical treatment, how blind people perceive the world, and the fascination with nothing found in King Lear. The students leave the course much enthralled and illuminated by absolutelynothing! Students in Larry Rudnick's "Nothing"

seminar experience hearing, speaking, and seeing nothing.

At the January 2005 American Astronomical Society meeting in San Diego, Mike Kelley presented a poster on Comet Encke which orbits the sun every 3.3 years and has exhausted its supply of fi ne particles. It is now giving off larger particles the size of pea gravel. The comet is basically “Riding a Trail of its own Debris” as it orbits. Each October, the Earth passes through Encke’s dust trail, producing celestial fi reworks called the Taurid meteor shower.

Until recently, astronomers could only study comets that periodically came blazing into our solar system. But those comets are not representative of all comets. The Spitzer telescope

dramatically expands our research options by allowing us to see phenomena that the Hubble cannot, including comets that have been in a deep freeze for long periods of time. Once comets approach the solar systems, they are heated by solar radiation and begin to shed ice, gases and grains of rock. Comet debris also includes organic materials and water. By studying the infrared “signatures” of elements shed by a wide variety of comets, scientists will be able to determine how similar or dissimilar they are to those found on earth.

This image was captured by Spitzer’s multiband imaging photometer when Encke was 2.6 times farther away than Earth is from the Sun. It is the best yet mid-infrared view of the comet at this great distance. Images like this are helping astronomers understand how rotating comets eject particles as they circle the Sun. On a larger scale, they expand our picture of the universe as a whole.

Len Kuhi Retires to Wine Country

Len Kuhi retired after teaching the Fall 2004 semester and is building a home in Cloverdale in the wine country of Sonoma County, California where he will live with his wife Mary Ellen, four dogs, and two horses. A farewell reception was held for Len at the Campus Club on November 17th and was well attended by University administrators and faculty. Following a nice reception and dinner, the evening featured a farewell speech by V. Rama Murthy, friend and fellow ex-VP for Academic Affairs, who made light of life in Morrill Hall. Then an exam committee took the stage to drill Len before he was allowed to retire. The panel consisted of: his wife Mary Ellen, development and home life expert, Ginny Olson, expert administrator, and Terry Jones, Bob Gehrz, and Chick Woodward, expert astronomers. Len was very quick to offer witty replies and he was "passed" unanimously by the assembled guests.

Born in Hamilton, Ontario, Len attended the University of Toronto and University of California, Berkeley, where he received a Ph.D. in Astronomy. He then started a brilliant career as a Professor at Berkeley, where he did research on T Tauri and Wolf-Rayet stars. In 1975 he became the Chairman of the Astronomy Department at Berkeley, then Dean of Physical Sciences in 1976, and fi nally, Provost and Dean of the College of Letters and Science from 1983-1989, before coming to Minnesota to be the Senior Vice President for Academic Affairs under President Nils Hasselmo. After his tenure as VP, Len soon became Chair of the Astronomy Dept., which lasted until this fi scal year, when he turned the reins over to Larry Rudnick. While Chair, Len was actively involved on several faculty committees, including the Senate Research Committee, Faculty Consultative Committee, and the Senate Committee for Finance and Planning. He was also very active nationally, as Treasurer of the American Astronomical Society, Chair of the AURA Board of Directors, and a member of the AIP Board of Directors.

Len was an excellent teacher and more than willing to carry twice the load of other faculty, when necessary. A sampling of student quotes include, “His ability to present his knowledge in a language us 'non-astronomers' can understand, is commendable.” And “Good experience, great teacher, great guy.” He was also instrumental in fundraising, getting us the capital needed to buy into the LBT Telescope and advance our Department to another level. We will all miss him!
