“Astronomers will announce major findings about planets outside our solar system, known as extrasolar planets, at a NASA Science Update at 3 p.m. EST today.” So says a media advisory just out from the agency. NASA TV plans to carry the event, which will discuss discoveries made by the Spitzer Space Telescope. The panelists:
Dr. Drake Deming, chief, planetary systems laboratory, NASA’s Goddard Space Flight Center, Greenbelt, Md.
Dr. David Charbonneau, assistant professor of astronomy,
Harvard-Smithsonian Center for Astrophysics, Cambridge, Mass.
Dr. Alan Boss, staff research astronomer, Department of Terrestrial Magnetism, Carnegie Institution of Washington
Dr. Kim Weaver, moderator; Spitzer program scientist, NASA’s Science Mission Directorate, Washington.
In Centauri Dreams, Paul Gilster looks at peer-reviewed research on deep space exploration, with an eye toward interstellar possibilities. For many years this site coordinated its efforts with the Tau Zero Foundation. It now serves as an independent forum for deep space news and ideas. In the logo above, the leftmost star is Alpha Centauri, a triple system closer than any other star, and a primary target for early interstellar probes. To its right is Beta Centauri (not a part of the Alpha Centauri system), with Beta, Gamma, Delta and Epsilon Crucis, stars in the Southern Cross, visible at the far right (image courtesy of Marco Lorenzi).
If you'd like to submit a comment for possible publication on Centauri Dreams, I will be glad to consider it. The primary criterion is that comments contribute meaningfully to the debate. Among other criteria for selection: Comments must be on topic, directly related to the post in question, must use appropriate language, and must not be abusive to others. Civility counts. In addition, a valid email address is required for a comment to be considered. Centauri Dreams is emphatically not a soapbox for political or religious views submitted by individuals or organizations. A long form of the policy can be viewed on the Administrative page. The short form is this: If your comment is not on topic and respectful to others, I'm probably not going to run it.
