David A. Hardy (astroart.org) / PPARC For the past several months, the number of known planets beyond our solar system has been hovering just above 100. But in the past week, four teams of planet hunters have announced the detection of nine new extrasolar planets, significantly bumping up the extrasolar planet tally. All of the planets were discovered using the radial velocity method, which measures the shifting spectral lines of a star being pulled to and fro by an orbiting planet.

SEARCH: Hubble Space Telescope advertisement New Era Dawns in Search for Other Worlds By Robert Roy Britt Senior Science Writer posted: 07:00 am ET 23 January 2002 WASHINGTON D.C. - At a meeting of the American Astronomical Society earlier this month, the Hilton and Towers hotel was loaded with more dust than a second-hand bookstore owner sees in a lifetime. It permeated the aisles of a conference hall where hundreds of posters presented fresh views of the universe, worked its way into rooms where researchers discussed their findings. Far from obscuring the gathering, astronomers announced they had peered through the dust to get the best view ever of the center of our galaxy. Mapped it to reveal the collision of stellar winds . More significant, they used mere dust grains to gain tantalizing new insights into the earliest stages of planet formation.

SEARCH: Hubble Space Telescope advertisement Other Worlds Not So Strange, Top Planet Hunter Says By Robert Roy Britt Senior Science Writer posted: 07:00 am ET 14 May 2002 BALTIMORE - The popular conception of planets around other stars involves strange worlds, all much larger than Jupiter on crazy paths in solar systems that look nothing like our own but within the planet-hunting community, that view has changed. Recent discoveries, along with the cleaning up of a few long-held misconceptions, reveal a handful of solar systems that are not so strange after all. Things out there are beginning to look a lot more like things back home. Geoffrey Marcy, a University of California at Berkeley researcher widely recognized as this world's top planet hunter, set the record straight in an interview with SPACE.com last week. "We're seeing characteristics that remind us of our own solar system, for sure," Marcy said. Those characteristics include planets smaller than Saturn, planets at more "normal" distances from their host stars, and planets whose orbits are pretty much circular instead of dramatically offset and elliptical. Marcy said that as the search technique used by his team and others improves, discoveries of these increasingly familiar worlds are coming at an ever faster pace compared to the stranger setups.

11. PRAXIS Publishing Astronomy & Space Sciences: Life On Other Worlds worlds Bookcover/link to New Scientist review Life on other worlds and How from thefrontiers of such diverse research topics as astronomy, biology, genetics http://www.praxis-publishing.co.uk/space/aliens.htm

Life on Other Worlds and How to Find It Stuart Clark Research into the possibility of life beyond Earth is no longer a fringe discipline. For example, a growing number of scientists now believe that microbial life will be found on Mars. In this fascinating new book, astrophysicist Stuart Clark considers the weight of modern scientific evidence and finds every reason to believe that life-forms should be as much a part of the cosmos as stars themselves. Drawing together strands from the frontiers of such diverse research topics as astronomy, biology, genetics and language theory, the author presents a cosmic tapestry for the general audience, showing life's inextricable bonds with the cosmos. With easy-to-understand examples, Stuart takes the reader on an intriguing journey into the deepest realms of the Universe, into the microscopic world of the living cell and back to the time of the dinosaurs. Life on Earth, it seems, is no chance accident nor is it anything miraculous. Instead, scientists are beginning to realise that each step is a perfectly consistent, perhaps even expected, step along the scientific ladder. So if life developed on Earth, then why not elsewhere? Ultimately, by explaining how life is so intrinsically linked with the laws of nature, this book brings the Universe a little closer to us all, and forces us to believe in the existence of extraterrestrials.

Astronomy Picture of the Day Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2000 August 10 Other Worlds and HD 38529 Illustration Credit: Lynette Cook Explanation: After the latest round of discovery announcements , the list of known worlds of distant suns has grown to 50 . While extrasolar planet discoveries are sure to continue, none - so far - points clearly to another planetary system like our own . Take, for example, the newly discovered parent star . Shining in Earth's night sky at 6th magnitude, this sun-like star lies 137 light-years away in the constellation Orion . Like most of the known extrasolar planets , HD38529's planet was discovered by detecting the telltale Doppler wobble in the parent star's spectrum. The data reveal that this planet orbits once every 14.3 days at an average of only 0.13 times the Earth-Sun distance and has a minimum of 0.77 Jupiter masses (about 240 Earth masses). There is even evidence in the wobble data that HD38529, and other stars with one known planet have additional massive planets orbiting them.

Life On Other Worlds and How to Find It by Stuart Clark, Praxis, £16.95, ISBN 185233097X PEOPLE are fascinated by the prospect of life in space. My proof? I count an even dozen volumes on bioastronomy on my bookshelf, all published within the past year. But among these, Stuart Clark's Life On Other Worlds and How To Find It is unique its in approach. We must walk before we run, says Clark. Don't even ask the age-old question "Are we alone?" until you 've brushed up on the basics. These basics are the principles and assumptions that underlie any search for life beyond our sphere. Here, Clark invokes the writings of Carl Sagan, Paul Davies, David Blair, Christian de Duve and many other respected experts. A swift tutorial on cosmic evolution takes us from the big bang to the formation of planets that might, just possibly, support life. This sets the stage for a lucid discussion of the emergence of life and exactly what constitutes a hospitable environment. The backdrop is a picture of Earth-like planets as commonplace among the myriad worlds in our Universe. But just because life could exist elsewhere is no guarantee that it does. To find out, we have to do the experiment. We have to collect the data. The search for life within our own Solar System has its roots in the 18th-century furore over supposed canals on Mars. Centuries later, the controversy continues, but now it is over the 1996 claim that a Martian meteorite contains microbial fossils. Exobiologists have not rejected the prospect of finding primitive life close to home. Several space missions are due to leave the drawing board and test for the presence of life.

Other Worlds in our Solar System? The Moons Sun Planets Mercury Venus Earth Earth's Moon ... All Planets How many worlds are there in our Solar System? If you answer 9, you would be incorrect. It is true that there are nine planets, but there are many more worlds. In fact altogether there are over worlds in the Solar System. Some are moons, and some are planets, but all are exciting. Many people think that moons are smaller than planets. This however is not true. There are several moons in the Solar System which are larger than both the planets Mercury, and Pluto. Neither are the moons less exciting then the planets. There are moons with volcanos, atmospheres, and even quite possibly liquid water oceans. The difference between what we call a moon, and what we call a planet has to do only with around what the world revolves, or circles. If the object circles the Sun it is called a Planet, however if it circles another world instead of the sun then it is called a moon. Moons sadly are often ignored, even though they are just as large splendid and exciting as the planets. Click on a planet to learn about its moons Neither Mercury nor Venus have any moons.

MadSci Network : Astronomy Re: Other worlds where H2S serves in place of H20? Date: Tue Apr 13 19:00:36 1999 Posted By: Nick Hoffman, Oil and Gas Exploration Geophysics - Melbourne, Australia Area of science: Astronomy ID: 923851588.As Message: Hi Jackson, I didn't see that programme - we don't get NOVA here in Australia :-) I can guess what it said though, because I've been researching this sort of thing in my spare time recently. One thing to get clear is that either you or NOVA have something a bit wrong about how the Bacteria uses H2S. If you look at these sorts of bacteria (and algae like Cyanidium caldarium that have equivalent chemistry) you find that their bodies are just like "normal" organisms, with body fluids based on water. They aren't full of liquid H2S. What they do is USE H2S as an energy source, instead of photosynthesising or eating "normal" energy foods like sugars and fats, and oxidising them. What they do is take in H2S and combine it with other chemicals to make sulphates, plus energy in the form of hydrogen ions.
