41. Astronomy And Earth Science: Pegasus 51 Pegasus 51. We have long dreamed of other worlds; we do not want tobe alone in the universe. The seventeenth century philosopher http://starryskies.com/articles/dln/10-95/peg51.html

Pegasus 51 We have long dreamed of other worlds; we do not want to be alone in the universe. The seventeenth century philosopher Giordano Bruno turned his eyes to the starry night, and said that, with so many stars, there must be other planets and other life. That idea, and the yearning not to be alone in a universe so incomprehensibly large, has stayed with us over the centuries. We have finally received a small reward for our yearnings, we have discovered at least one planet around a star like our Sun. We have spent decades searching the cosmos. We have turned radio telescopes to the skies and listened for signs of life. Sadly, the biggest listener, SETI (Search For Extraterrestrial Intelligence) has been lost to government budget cuts. But there are a few more groups still listening. The other method of searching, is to look, though just what to look for is pretty tricky. With billions of stars in our galaxy, astronomers have to decide which stars to watch. They must not be too far away or the planets might not be detected at all. Another factor is the type of star. If we are looking for planetary systems that might have intelligent life, then we need to narrow our search for middle aged yellow stars like our sun. Stars more massive than the Sun live a fast and furious life, there is not time enough for intelligent life to develop. Our Sun is known as a G class star, and that’s the type astronomers narrowed their search to.

This is an easy-to-understand scaling of the Universe in both space and time. Distances in space are represented by the time light takes to travel there.

SAO Project 29 Information Project #29. Search for Other Worlds Science fiction 20 years ago, reality today. Investigate one of the terms of the Drake Equation for which astronomers have actually made tangible progress towards solving - the fraction of stars with planets. How exactly do astronomers search for and detect planets around other stars? To achieve high marks for this project you will need to outline the basic observational techniques currently employed by such extra-solar planet hunters, and demonstrate an appreciation for the strengths (and just as important, the weaknesses) of these techniques. You should also discuss the properties of the planetary systems found to date and how they relate to our previous understanding based on only one known system. Finally, an assessment of the near- and long-term prospects for finding terrestrial-like planets should be included. Below I list some web sites and reference books to get you started. The books are not to be regarded as "must buy". They are not required reading for each project, because there is no required reading! I list well known books that I hope can be found in libraries. I am happy to comment on a summary of what you intend to do ( in fact please send me a summary as soon as possible so I know you are on track Caution! The Internet

The Encyclopedia of Astrobiology, Astronomy, and Spaceflight FRONT PAGE NEWS ARCHIVE NEWSLETTER ... Z this site WWW space colony A large, self-contained, artificial environment in space that is the permanent home of an entire community. The first fictional account of a space colony appears in 1869 in Edward Everett Hale ’s novel, The Brick Moon Other early portrayals of the idea are to be found in novels by Jules Verne in 1878 and Kurd Lasswitz in 1897. In the 1920s, J. D. Bernal described spherical colonies that have come to be known as Bernal Spheres . The companion idea of mobile colonies, or generation starships , that could carry large numbers of people relatively slowly to other stars was envisioned in 1918 by Robert Goddard A vastly more ambitious scheme for completely encircling a star with artificial habitats was described by Freeman Dyson Indeed, the development of concepts about space colonies is deeply entwined with evolving notions about the colonization of other worlds, terraforming , and space stations.

Is There Life on Other Worlds? By H. P. Blavatsky (from The Secret Doctrine Did the Ancients know of worlds besides their own? . . . That time is gone by for ever, when, although our pious ancestors believed that our earth was in the center of the universe, the church and her arrogant servants could insist that we should regard as a blasphemy the supposition that any other planet could be inhabited. Adam and Eve, the Serpent, and the Original Sin followed by atonement through blood, have been too long in the way, and thus was universal truth sacrificed to the insane conceit of us little men. Now what are the proofs thereof? Except inferential evidence and logical reasoning, there are none for the profane. To the Occultists, who believe in the knowledge acquired by countless generations of Seers and Initiates, the data offered in the Secret Books are all-sufficient. The general public needs other proofs, however . . . . We may approach the subject from its general aspect, and see whether belief in it is so very absurd, as some scientists along with other Nicodemuses would have it. Unconsciously, perhaps, in thinking of a plurality of inhabited " Worlds

PREDICTABLE ASTRONOMICAL EVENTS Anyone visiting their local bookstore or public library sees hundreds of books on astronomy. Topics range the full gamut; from asteroids colliding with Earth (e.g., extinction of the dinosaurs) to the possibilities of life on other worlds (e.g., exobiology or the Search for Extra-Terrestrial Intelligence; a.k.a. SETI). There are yearly almanacs with tables listing positions of the sun, moon, and planets as well as pictorial table top books showing how the planets and galaxies look through the cameras of deep space probes or the Hubble Telescope. If you need to know how to build a telescope or photograph galaxies, the sources are just a short walk or drive away. It won't be too long when all this information becomes accessible to anyone on their personal computer through the World Wide Web ; for example in just seconds. This book (more like a handbook) is intended to provide a general appreciation for the rarity of planetary, lunar, and solar configurations in the sky. Unlike many books on astronomy, I have attempted to show the rhythm of the planets and their moons and have provided excellent references in each footnote for those seeking more details. The bibliography also suggest additional reading sources for those interested. There are undoubtedly more examples of interesting and unusual celestial alignments which I encourage you to explore with today's astronomy software. The bottom line is that if you are not motivated to take your telescope or binoculars outside one very cold winter's night, maybe you will if you realize that you won't have a second chance to observe a once-in-a-lifetime Predictable Astronomical Event.
