Project ASTRO-NM Teachers/Astronomer Workshop
The New Mexico Museum of Space History and the Astronomical Society of the Pacific are partnered to bring Project ASTRO-NM to you. The program is a national effort to pair a classroom teacher in grades 3-12, with a professional, amateur, or graduate student astronomer. Selected teachers and astronomers come together in a workshop and learn to become equal partners; teachers provide the educational expertise, while the astronomers provide the astronomical knowledge. The partners receive 14 hours of training. The next training workshop will be held at Sunspot, New Mexico, September 29-30, 2006. All expenses for this event are paid for. (Except travel) For more information visit the New Mexico Museum of Space History Web site or call 1-877-333-6589 or (505) 437-2840.

NASA's Spitzer Space Telescope Discovers Giant Stars
Modified from Mega Solar Systems Discovered
NASA's Spitzer Space Telescope has recently discovered potential solar systems surrounding two massive stars, 30 and 70 times the mass of our Sun. Astronomers believe these disks contain massive quantities of icy material, similar to the Kuiper belt found in our own Solar System, but extending out 60 times more distant than Pluto's orbit. These two huge "hypergiant" stars are circled by disks of what might be planet-forming dust. The findings surprised astronomers because stars as big as these were thought to be inhospitable to planets. Disks have been spotted before around stars five times more massive than the sun.
Astronomers estimate that the stars' disks are also bloated, spreading all the way out to an orbit about 60 times more distant than Pluto's around the sun.. These dusty structures might represent the first or last steps of the planet-forming process.
Stars as massive as these don't live very long. They burn through all of their nuclear fuel in only a few million years, and go out with a bang, in fiery explosions called supernovae. Their short life spans don't leave much time for planets, or life, to evolve. Any planets that might crop up would probably be destroyed when the stars blast apart. An artist concept of a hypergiant and its disk, plus additional graphics and information, are available at NASA's Planetary Photojournal Web site.
(Solar TErrestrial RElations Observatory) is the third mission in NASA's Solar Terrestrial Probes program. This two-year mission will provide a unique and revolutionary view of the Sun-Earth System. The two nearly identical observatories — one ahead of Earth in its orbit, the other trailing behind — will trace the flow of energy and matter from the Sun to Earth as well as reveal the 3D structure of coronal mass ejections and help us understand why they happen. STEREO will also provide alerts for Earth-directed solar ejections, from its unique side-viewing perspective adding it to the fleet of Space Weather detection satellites.
Why the need for STEREO? Coronal mass ejections (CMEs) are powerful eruptions that can blow up to 10 billion tons of the Sun's atmosphere into space. CMEs can trigger severe magnetic storms when they collide with Earth's magnetosphere. Large geomagnetic storms can damage and even destroy satellites, are extremely hazardous to astronauts when outside of the protection of the Space Shuttle or the International Space Station, and they have been known to cause electrical power outages. Yet despite their importance, scientists don't fully understand the origin and evolution of CMEs, nor their structure or extent in interplanetary space. STEREO's unique stereoscopic images of the structure of CMEs will enable scientists to determine their fundamental nature and origin.
STEREO's launch has slipped to the next launch window. It will now launch no earlier than Aug. 20.
Modified from Early Galaxies Looked Similar
An international team of astronomers have recently performed one of the most detailed surveys of the most distant galaxies. These galaxies are so far away, we see them as they looked when the Universe was less than half its current age. One of the big surprises of this survey; however, is how much these young galaxies match the structures we see in the current Universe. This means that galaxies probably evolved through collisions and mergers much earlier than previously believed.
The knowledge of early galaxies has made major progress in the past ten years. Astronomers are using the new "Lyman-break technique" (combining ultraviolet and infrared measurements). This technique allows very distant galaxies to be detected. They are seen as they were when the Universe was much younger, thus providing clues to how galaxies formed and evolved. Astronomers can now determine the formation rate for stars in distant galaxies. Stars in these distant galaxies formed at a rate of a few hundred to one thousand stars per year (only a few stars currently form in our Galaxy each year). The team also studied the galaxies’ morphology, and found that most are spiral galaxies. Up to now, distant galaxies were believed to be mainly interacting galaxies, with irregular and complex shapes. It has now been shown that these galaxies, seen when the Universe was about 40% of its current age, have regular shapes — similar to present-day galaxies like ours. They bring a new element to our understanding of the evolution of the galaxies.
Modified from Wild Weather: Iron Rain on Failed Stars
Ever since their discovery 11 years ago, brown dwarfs have baffled scientists. First it was the question of how to categorize them. These celestial orbs are too massive to be a planet and not massive enough to be a star. Now scientists are investigating astonishing weather patterns on brown dwarfs that could rival Jupiter's Great Red Spot and Earth's intense hurricanes.
Brown dwarfs are sometimes called “failed stars”. They are too small to trigger the fusion of hydrogen that keeps stars like our sun shining for billions of years. Instead, over tens of millions of years brown dwarfs slowly cool and fade. Studying brown dwarfs has proven difficult; to get a better "look" at brown dwarfs, scientists have relied on infrared-capable telescopes and mathematical models. Over time, as the glowing body of a brown dwarf cools, metallic clouds form! The iron condenses to form iron-rich clouds and droplets of liquid-iron rain. This recent discovery was unexpected. Not only did scientists find these metallic clouds, but they also spotted evidence of violent storms. Thermodynamics would predict that as brown dwarfs release heat, they would dim. But the astronomers found that the older brown dwarfs shined brighter than the warmer, younger ones.
But what causes the cloudy disturbance? With cooling, a brown dwarf's cloud layer sinks closer to its surface. As the clouds form deeper in the atmosphere, they are more sensitive to the winds and convective motions in the atmosphere. This probably leads to the destruction of the clouds. But there are still many unanswered questions. For instance, what do these storms look like? Scientists predicts that in the next 10 to 15 years very large telescopes will exist, making it possible to gather more detailed information about these storms.
