Workshops and Courses

The Heat from Within: A Field-Based Workshop
Intermediate grade level science teachers and other educators are invited to spend 12-19 July 2009 with planetary scientists investigating different types of volcanos in the Bend and Crater Lake regions of Oregon. Contrast these Earth-based analogs with volcanic features on Mars, the Moon, Venus, and even the moons of Jupiter, Saturn, and Neptune! From field experiences and classroom exercises, participants build an understanding of the planetary processes that produce volcanos, and the patterns of volcanism on planets in our solar system. The experience will be divided between the field and lab, where participants work with classroom-tested, hands-on inquiry based activities and resources that can be used to enhance Earth and space science teaching in the classroom.Applications are due April 7, 2009.

Events/Opportunities

NASA's Endeavor Science Teaching Certificate
NASA has unveiled the Endeavor Science Teaching Certificate Project. The goal of the project is to ensure that teachers across the country can use the discoveries that NASA makes on a daily basis to inspire the next generation of explorers, scientists, engineers, and astronauts. The program will provide workshops, online and on-site graduate courses and NASA content and materials to teachers and students in K-12 classrooms. NASA will work in partnership with state departments of education to ensure program participants can apply credit from project courses towards state certification requirements.

Earth and Space Science Webcasts for Teachers
The NASA Digital Learning Network features a variety of upcoming Webcasts for teachers.

National STEM Careers Competition and Project for High School Students
The "No Boundaries" project collaboration introduces students to the limitless opportunities at NASA and hopefully, encourages them to work toward STEM careers. For this project, teachers assign student groups to STEM fields. Students research a NASA career, and develop and present a project to share and enter into the competition. Entry Deadline: May 15, 2009.

New Evidence: Brown Dwarfs Form from Collapsed Gas
Modified from http://www.universetoday.com/2008/12/03/brown-dwarfs-form-like-stars/

Brown dwarfs are too small to be called stars and too large to be called planets. Typically, brown dwarfs have masses between 15 and 75 times that of Jupiter. More massive objects will develop nuclear fusion in their cores and be considered stars. As a result, brown dwarfs are sometimes called failed stars. Astronomers haven't been sure whether brown dwarfs form like stars, from the gravitational collapse of gas clouds, or if they form like planets, where rocky material comes together until it grows massive enough to draw in nearby gas.

Astronomers have now found evidence that brown dwarfs form more like stars. Using the Smithsonian's Submillimeter Array, astronomers detected molecules of carbon monoxide shooting outward from a brown dwarf. This type of molecular outflows typically is seen coming from young stars or protostars. However, this object has an estimated mass of 60 Jupiters-- a brown dwarf.

Milky Way Twice as Massive as Thought
Modified from http://www.cfa.harvard.edu/press/2009/pr200903.html

The Milky Way is faster, heavier, and more likely to collide than we thought. Astronomers making high-precision measurements of the Milky Way say our Galaxy is rotating about 100,000 miles per hour faster than previously understood. That increase in speed increases the Milky Way's mass by 50 percent, bringing it even with the Andromeda Galaxy. Our solar system is about 28,000 light-years from the Milky Way’s center, moving at about 600,000 miles per hour in our Galactic orbit.

Pure Water on Mars
Modified from http://www.universetoday.com/2009/01/20/lots-of-pure-water-ice-at-mars-north-pole/

Mars' north polar cap contains water ice "of a very high degree of purity," according to an international study. Using radar data from the Mars Reconnaissance Orbiter, researchers say the water is at 95 percent purity in the polar ice cap. The north polar cap is a dome of layered, icy materials, with mostly ice and a small amount of dust. Combined, the north and south polar ice caps are believed to hold two to three million cubic kilometers (0.47-0.72 million cu. miles) of water ice, roughly 100 times more than the total volume of North America's Great Lakes.

Mars southern polar cap was once thought to be carbon dioxide ice, but the Mars Express confirmed that it is composed of a mixture of water and carbon dioxide.

Which Came First, Black Holes or Galaxies?
Modified from http://www.universetoday.com/2009/01/07/which-comes-first-galaxy-or-black-hole/

Astronomers have been trying to determine whether galaxies form first and then a black hole springs up in the center, or galaxies form around an already existing black hole. New evidence shows that the black holes form before the host galaxy, and somehow grow a galaxy around them.

Previous studies of galaxies and their central black holes in the nearby Universe revealed a connection between the masses of the black holes and of the central "bulges" of stars and gas in the galaxies. The bigger the galaxy bulge is, the more massive the black hole at the heart of that galaxy is. This ratio is nearly the same for a wide range of galactic sizes and ages. But astronomers have now measured this ratio in galaxies formed in the first billion years after the Big Bang. The black holes in these young galaxies are much more massive compared to the bulges than those seen in the nearby Universe, implying that the black holes started growing first.

Mars is Alive?
Modified from http://science.nasa.gov/headlines/y2009/15jan_marsmethane.htm?list812372

Mars is a world of cold deserts, apparently without life of any kind. Mars' atmosphere is so thin, any liquid water on the surface quickly boils away, while the Sun's ultraviolet radiation scorches the ground. But the recent detection of methane in the atmosphere of Mars indicates that Mars is still alive, in either a biologic or geologic sense. A team of scientists found methane in the atmosphere of Mars by carefully observing the planet over several Mars years using spectrometers attached to telescopes at NASA's Infrared Telescope Facility and the W. M. Keck telescope, both at Mauna Kea, Hawaii. According to the team, the plumes were seen over areas that show evidence of ancient ice or flowing water.

Methane is quickly destroyed in the Martian atmosphere, so the discovery by scientists of substantial plumes of methane indicates some process is releasing the gas. Methane is the main component of natural gas on Earth. Much of Earth's methane come from living organisms. However, life is not required to produce the gas. Other purely geological processes, like oxidation of iron, also release methane. Another possibility is vulcanism. It will take future missions, like NASA's Mars Science Laboratory, to discover the origin of the Martian methane.
