In what could be a major breakthrough in the search for extrasolar planets, a team of astronomers announced today the discovery of 16 planet candidates in the central bulge of our galaxy. In an article in the October 5 issue of Nature magazine, lead author Kailash C. Sahu of the Space Telescope Science Institute and his colleagues describe how they used the Hubble Space Telescope to observe a batch of stars near the central bulge of the galaxy, at distance of up to 26,000 light years – ten times farther away than any planet previously found. The detections, they point out, not only add to our knowledge of specific planets, but also strongly suggests that planets are just as plentiful in the star-rich regions near the center of the galaxy as they are in our neighborhood on the galactic rim.

We are finally defining the terms of the Drake equation," he added, referring to the famous formula for estimating the number of communicating alien civilizations. "Sadly, Carl Sagan is not with us to see all the discoveries that have been made in the 10 years since his death."

Bislang war das Weltraumteleskop Hubble nicht als bedeutender extrasolarer Planetenjäger aufgefallen. Doch das hat sich nun geändert: In der heutigen Ausgabe des Wissenschaftsmagazins Nature wird die Entdeckung von insgesamt 16 extrasolaren Planeten bekannt gegeben, die im Rahmen einer systematischen Durchmusterung mit Hubble entdeckt wurden.
