Events/Opportunities

Building Information Technology Skills through Astronomy
The National Optical Astronomy Observatory (NOAO) is pleased to announce a new program (BITS through Astronomy) offering Arizona middle school science teachers help in preparing students for science career pathways. Through the excitement of astronomical image processing, teachers can introduce their students to analytical computer skills, including interpreting graphs, using statistics, and understanding equations. We will offer selected middle school teachers: four multi-day summer workshops, the first beginning in June 2007, collaborative work via telecommunication with astronomers and other teachers and on-going connections during the school year, stipends to cover time spent on this project, and laptops for implementing image processing projects in their classroom. We invite interested teachers to email us, telling why they are interested in this program, and how they think it could benefit their students. Please give details of your school and student population, and outline what computer support is offered at your school. This program is only open to teachers in the state of Arizona. For more information, email Dr. Katy Garmany at Garmany@noao.edu, or call her at 520-318-8526.

Mission News and Science

The Brightest Supernova Ever
Modified from http://science.nasa.gov/headlines/y2007/07may_bigsupernova.htm?list812372

Artist's illustration of supernova SN 2006gyThe brightest stellar explosion ever recorded may be a long-sought new type of supernova, according to observations by NASA's Chandra X-ray Observatory and ground-based optical telescopes. This explosion was a hundred times more energetic than a typical supernova, from an enormous star 150 times the mass of our Sun . The observations indicate that the explosions of extremely massive stars in the early universe were a different more violent type of supernova than those usually observed in the modern universe.

Astronomers think many of the first stars in the Universe were this massive, and this new supernova may thus provide a rare glimpse of how those first generation stars died. The observations of the supernova, known as SN 2006gy, provide evidence that the death of such massive stars is fundamentally different from theoretical predictions. Supernovas usually occur when massive stars exhaust their fuel and collapse under their own gravity. In the case of SN 2006gy, however, astronomers think that a very different effect may have triggered the explosion. Under some conditions, the core of a massive star produces so much gamma ray radiation that some of the energy from the radiation converts into particle and anti-particle pairs. The resulting drop in energy causes the star to collapse under its own huge gravity. After this violent collapse, runaway thermonuclear reactions ensue and the star explodes, spewing the remains into space. The SN 2006gy data suggest that spectacular supernovas from the first stars that spew their remains - rather than collapsing to a black hole as theorized - may be more common than previously believed.

NASA Antenna Cuts Mercury to Core, Solves 30 Year Mystery
Modified from http://www.jpl.nasa.gov/news/news.cfm?release=2007-050

Diagram showing the interior structure of Mercury. The metallic core extends from the center to a large fraction of the planetary radius. Radar observations show that the core or outer core is molten.Researchers working with high-precision planetary radars have discovered strong evidence that the planet Mercury has a molten core, changing our view of Mercury’s composition and how Mercury and the other planets in our Solar System first formed. The molten core explains the weak magnetic field around Mercury detected by the Mariner 10 spacecraft in 1974 and 1975.

Among Mariner 10’s discoveries was that Mercury had its own weak magnetic field - about one percent as strong as that found on Earth. This was unexpected—scientists believe that Earth’s magnetic field is generated by a rotating molten outer core, and Mercury was believed too small to have a molten core. Scientists theorized that Mercury consisted of a silicate mantle surrounding a solid iron core. This iron was considered solid - or so the theory went - because small planets like Mercury cool off rapidly after their formation. If Mercury followed this pattern, then its core should have frozen long ago.

In 2002, scientists began pointing some of our most powerful antennas at Mercury. Using the radar echoes off of Mercury’s surface, scientists calculated Mercury's spin rate to an accuracy of one-thousandth of a percent. With these data the science team was able to detect tiny twists in Mercury's spin as it orbited the Sun. These small variations were double what would be expected for a completely solid body. This finding ruled out a solid core, so the only logical explanation remaining was that the core - or at the very least the outer core - is molten and not forced to rotate along with its shell.

Maintaining a molten core over billions of years requires that it also contain a lighter element, such as sulfur, to lower the melting temperature of the core material. The presence of sulfur supports the idea that radial mixing, or the combining of elements both close to the Sun and farther away, was involved in Mercury's formation process.

Flyby of Jupiter
Modified from http://science.nasa.gov/headlines/y2007/01may_fantasticflyby.htm?list812372

Jupiter's Little Red SpotNASA has released stunning new images of Jupiter and its moons taken by the New Horizons spacecraft. Views include a movie of a volcanic eruption on Jupiter's moon Io; a nighttime shot of auroras and lava on Io; a color photo of the "Little Red Spot" churning in Jupiter's cloudtops; images of small moons herding dust and boulders through Jupiter's faint rings--and much more.

New Horizons came within 1.4 million miles of Jupiter on Feb. 28 in a gravity assist maneuver designed to trim three years off its travel time to Pluto. For several weeks before and after this closest approach, the probe trained its cameras and sensors on Jupiter and its four largest moons.

A highlight of the flyby was the first close-up color scan of the Little Red Spot. This storm is about half the size of Jupiter's larger Great Red Spot and about 70 percent of Earth's diameter. It formed in the late 1990s when three smaller storms collided and merged. The combined storm started out white, but began turning red about a year ago. Using New Horizons data, scientists will be able to search for clues about how these great storm systems form and why they change colors.

Tvashtar volcano and plume on IoOf Jupiter's four largest moons, the team focused much attention on volcanic Io, the most geologically active body in the solar system. New Horizons' cameras captured pockets of bright, glowing lava scattered across the surface; dozens of small, glowing spots of gas; and several views of a sunlit umbrella-shaped dust plume rising 200 miles into space from the volcano Tvashtar, the best images yet of a giant eruption from the tortured volcanic moon.

The timing and location of the spacecraft's trajectory also allowed it to spy many of the mysterious, circular troughs carved onto the icy moon Europa. Data on the size, depth and distribution of these troughs, discovered by the Jupiter-orbiting Galileo mission, will help scientists determine the thickness of the ice shell that covers Europa's global ocean.
