Wanted: A STEM Workforce

by Michael G. Gibbs

As a cause-based organization, the Astronomical Society of the Pacific (ASP) strives to improve science literacy through the enjoyment of astronomy within the United States and internationally. This mission is implemented by working in partnership with the intermediate communicators who interact and educate both children and the public. This important mission is shared with other organizations that also seek to increase the knowledge of our nation in the fields of science, technology, engineering and mathematics (STEM).

While the ASP works with numerous organizations that share in its mission, there are still others who continue the pipeline of developing and educating our nation’s future STEM workforce and leaders. One such organization is Capitol College.

Recently, Capitol College established the Center for Space Science Education and Public Outreach. The Center provides hands-on educational and workforce development experiences for K–12, community college, and college students (and those who support them) in achieving leadership careers in STEM fields.

The Universe Brought Down to the Streets

by Megan Watzke and Kimberly Arcand

The International Year of Astronomy 2009 (IYA2009) brought an unusual set of opportunities for those of us in the profession of communicating astronomy. How could we contribute to the lofty, yet incredibly important IYA2009 goals that included "stimulating worldwide interest…in astronomy and science"?

Our answer was somewhat simple: put astronomy in unexpected places. Moreover, take advantage of astronomy in its most attractive and accessible form -- its spectacular imagery -- to introduce the wonders of the cosmos to the widest possible audiences. By treating science akin to art in its presentation, we hoped that people around the world might be introduced to the excitement and intrigue astronomy has to offer.

The resulting project was "From Earth to the Universe," or FETTU for short. To date, there have been more than 500 FETTU exhibitions in nearly 70 countries on every continent (except Antarctica). In the United States, there have been more than 40 exhibits in 25 states around the country. 

Gamma-Ray Bursts: Piecing Together a Cosmic Puzzle

by Zach Cano

Since the serendipitous discovery of GRBs by US spy satellites in the 1960s, thousands of papers have put forward numerous ideas and models to explain the occurrence of the brief flashes of highly energetic gamma rays. But our lack of understanding is not as dire as perhaps it first seems, for key observations during the last 20 years have allowed astronomers to piece together at least part of the puzzle surrounding the GRB phenomenon. Even more exciting, the questions resulting from these observations provide all of astro-physics with the mouth-watering prospect of revealing new physical processes that will not only decipher the long-standing GRB puzzle, but will also increase our understanding of fundamental astrophysics in general.

First Temperate Exoplanet

European Southern Observatory

Combining observations from the CoRoT satellite and the ESO HARPS instrument, astronomers have discovered the first
"normal" exoplanet that can be studied in great detail. Designated Corot-9b, the planet regularly passes in front of a star similar to the Sun located 1500 light-years away from Earth towards the constellation of Serpens (the Snake).

"This is a normal, temperate exoplanet just like dozens we already know, but this is the first whose properties we can study in depth," says Claire Moutou, who is part of the international team of 60 astronomers that made the discovery. "It is bound to become a Rosetta stone in exoplanet research."

"Corot-9b is the first exoplanet that really does resemble planets in our solar system," adds lead author Hans Deeg. "It has the size of Jupiter and an orbit similar to that of Mercury."

"Like our own giant planets, Jupiter and Saturn, the planet is mostly made of hydrogen and helium," says team member Tristan Guillot, "and it may contain up to 20 Earth masses of other elements, including water and rock at high temperatures and pressures."

Corot-9b passes in front of its host star every 95 days, as seen from Earth. This "transit" lasts for about 8 hours, and provides astronomers with much additional information on the planet. This is fortunate as the gas giant shares many features with the majority of exoplanets discovered so far.

More than 400 exoplanets have been discovered so far, 70 of them through the transit method.
