Score for Ander Mikalson's Big Bang piece

Choral Performance of Primordial Sound of the Big Bang

On Friday April 13, at 7:30pm there was a performance by the VCU Commonwealth Singers of a new choral work to recreate the primordial sound that accompanied the birth of the Universe. UVa astronomer Mark Whittle has worked to reconstruct the sound waves that were present in the first million years of the Universe’s life and sound artist Ander Mikalson has created an eight-part choral work that is both honest to our scientific understanding of the primordial sound, and also fascinating and moving to listen to.

The event, which is free and open to the public, will be held at St. James Episcopal Church in Richmond this Friday April 13th, starting at 7:30pm. In addition to the performance of the piece, there will be a discussion with Mark Whittle as well as the composer Ander Mikalson, along with the conductor and a soloist from the VCU Commonwealth Singers, followed by a "tour through the early universe" led by Mark Whittle.



Caroyl Gooch at McCormick Observatory

Article by Geneviève de Messières on the History of McCormick Observatory in July 2011 Griffith Observer

UVA Astronomy graduate student Geneviève de Messières won first prize in the 2011 Science Writing Awards, sponsored by Boeing and conducted by the Griffith Observatory, for her article on the history of the astronomy program at Leander McCormick Observatory. She joined senior scientist Ricky Patterson in giving a tour of the observatory to Caroyl Beddow Gooch, a Charlottesville resident who worked there as a computer in the 1940s as a young woman. The article, which appears in the July 2011 issue of the Griffith Observer, includes Gooch’s recollections of her time at McCormick as well as perspective on the role of women in that era of astronomy and the significance of the parallax program at McCormick Observatory.





Astronomy Club’s Book Helps Kids Shoot for the Stars

Last year, University of Virginia astronomer Kelsey Johnson and a team of student volunteers established an astronomy club, called "Dark Skies, Bright Kids," in rural southern Albemarle County elementary schools.

They are seeking to spark early interest in astronomy among children who live far enough away from bright city lights to actually get a great view of the night sky. They hold weekly after-school meetings, and, every other Friday night, set up telescopes on school grounds for family-oriented sky gazing.

The schools there have a large Hispanic population, so Johnson and her team - drawn mostly from the Astronomy department - also are reaching out to students whose native language is Spanish.

They now have a bilingual astronomy art book, "Snapshots of the Universe," which they hope to distribute to all Virginia 3rd grade classrooms and elementary school library. You can help by "voting" for their project at the Pepsi Refresh website. You can vote throughout the month of August.

Record seasonal snowfall at McCormick Observatory this winter

McCormick Observatory sees record snowfall this winter

On February 10, 2010 at 8:00 am, a snowfall of 3.8 inches was recorded at the McCormick Observatory weather station. This brought the seasonal total to 55.0 inches for this station, and broke the previous record of 54.7 inches set during the winter of 1995-96. Accumulation from two storms this winter rank them in the top ten overall since 1894 at McCormick Observatory, and there have been three events with more than ten inches of accumulation each. Snowfall varies widely from year to year in Virginia, but seasonal snowfall is typically around 18 inches for this station.

McCormick Observatory, which celebrates its 125th anniversary this April 13th, has served as the weather station of record for the Charlottesville area since before 1894, as a National Weather Service Cooperative Observing Station as well as a member of the United States Historical Climatology Network. Members of the Astronomy Department have carried out these measurements for more than a century.



Tidal Debris aids in Determination of Size and Shape of Milky Way Dark Matter Halo

Tidal Debris aids in Determination of Size and Shape of Milky Way Dark Matter Halo

UVa Astronomer Steven Majewski and colleagues have used observations of the Milky Way Galaxy’s interaction with a disintegrating dwarf galaxy to model the shape of the dark matter halo of the Milky Way. The Sagittarius dwarf galaxy is being shredded by the tidal force of the Milky Way, and the remnants of the dwarf galaxy are now distributed across much of the sky. It is possible to infer the orbital motion of these fragments, and this allowed Majewski and colleagues to measure the size and shape of the halo of our own galaxy. A Milky Way with a halo of a different size and shape would affect the "tidal debris" from Sagittarius in a different way, causing the orbit to change. Therefore, sufficiently sensitive observations of the motions of this tidal debris allow strict limits to be placed on the actual size and shape of the halo of the Milky Way. Because the tidal debris is reacting to the entire mass of the Milky Way, most of which is in the form of Dark Matter, Majewski and collaborators were able to determine the shape of the dark and luminous matter halo of the Milky Way.

The work was carried out with collaborators David Law (UCLA) and Kathryn Johnston (Columbia), and was presented at the January meeting of the American Astronomical Society.



Astronomers Use Radio Telescope to Find Rare Supernova Explosion

Chevalier and Collaborators Identify Rare Type of Supernova Explosion

UVa Astronomer Roger Chevalier graduate student Ori Fox, former UVa Postdoc Poonam Chandra, along with an international team of astronomers led by Alicia Soderberg of the Harvard-Smithsonian Center for Astrophysics, used the Very Large Array radio telescope to identify a rare type of supernova.

Their results were published in the journal Nature on January 28th. The supernova, SN2009bb, appears to be of a type previously only discovered through the presence of extremely energetic gamma rays. In the caseof SN2099bb, the presence of very low energy radio waves (detected at the Very Large Array) were used to infer the presence of vast amounts of energy, similar to that seen in the gamma-ray blasts. These observations suggest the presence of a "central engine" (either a black hole or neutron star) which accelerates the material up to speeds approaching the speed of light.








Giant Intergalactic Gas Stream Longer Than Previously Believed

Giant Intergalactic Gas Stream Longer Than Previously Believed

UVa Astronomy Research Associate David Nidever and Professor Steven Majewski, along with their colleagues Butler Burton (NRAO) and Lou Nigra (U. Wisconsin), used the Green Bank Telescope to show that a giant intergalactic gas stream is longer and older than previously thought. The Magellanic Stream flows from the Milky Way’s two largest satellite galaxies, the Magellanic Clouds, and stretches over 200 degrees across the sky. The astronomers presented their findings to the American Astronomical Society’s meeting in Washington, DC and submitted their work for publication in The Astrophysical Journal.

It is hoped that the spacecraft will pass through the plumes from the ice fountains, allowing it to sample the particles and determine their composition. Anne is an associate member of the Cassini team, and studies the icy bodies of the outer Solar System.




Dark Skies, Bright Kids

Dark Skies, Bright Kids program started by Kelsey Johnson

University of Virginia Astronomy Professor Kelsey Johnson has started an astronomy club called "Dark Skies, Bright Kids" at a local elementary school. The after-school program at Red Hill Elementary School designed to expose rural elementary school students to the science behind Albemarle County’s unpolluted and clear dark nighttime skies.

One of Johnson’s motives in implementing the club at Red Hill was the rural school’s high percentage of low-income families. She noted that 50 percent of elementary school students in southern Albemarle County qualify for free or reduced lunch, an indicator of the area’s socioeconomic status. According to Johnson, the NSF grant-backed club will boost the "science education of the ‘rural poor.’"








Saturn’s Largest Ring

Solar System’s Largest Planetary Ring Discovered by UVa Astronomers

UVa Astronomy’s Anne Verbiscer and Mike Skrutskie, along with their colleague Douglas Hamilton (U. Maryland) have used the Spitzer Space Telescope to discover the largest planetary ring in the Solar System. The ring, which orbits the planet Saturn, is 13 million kilometers in radius, or about 200 times the radius of the giant planet itself. Verbiscer, Skrutskie and Hamilton have also shown how repeated impacts on Saturn’s moon Phobe can keep the ring supplied with dust. The ring may also be the cause of the two tone coloration on the surface of another Saturnian moon, Iapetus.

Their results are presented in this week’s Nature. More details can also be seen on our Picture of the Month page.

NGC 2770

LBT First Binocular Light

The Large Binocular Telescope has successfully achieved first “binocular” light. UVa is a partner in the LBT, which has two 8.4-meter mirrors that combine to give the light gathering power of a single 11.8-meter mirror, making the LBT the largest single telescope in the world. Eventually, the two separate mirrors will work to combine the light interferometrically, and the LBT will have the resolution of a telescope equivalent to a 22.8-meter mirror (far exceeding that of the Hubble Space Telescope).

This image of NGC 2770 (by Vincenzo Testa of Rome Observatory) was made by combining images taken in three different filters. The total observation time was about 12 minutes.
