14. SPACE.com -- Other Worlds Not So Strange, Top Planet Hunter Says The popular view of extrasolar planets as strange worlds has changed inside theplanethunting community based on the most recent findings. http://www.space.com/scienceastronomy/astronomy/exoplanet_status_020514-1.html

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. able > SCIENCE TUESDAY Visit SPACE.com to explore a new science feature each Tuesday.

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

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.

Welcome to the 2006 Science Olympiad! Our company's mission is to provide effective, reasonably priced coaching aides to help reduce the number of hours coaches, parents and other volunteers would otherwise spend in preparing their teams for the Science Olympiad competitions. New products to support the 2006 Science Olympiad events will be posted in October. Please check back. Thank you. We have bought a lot of things from you over the past few years, and have never been dissatisfied. You have a great company there that puts out quality items that are definitely of assistance to SO teams. Thanks for all that you do for SO. Pam New and Revised Products for 2005 STELLAR JOURNEY: The Game was created in cooperation with the Chandra X-ray Center as an exciting, creative tool for students and adults to dis-cover the fascinating world of stars. STELLAR JOURNEY: The Game presents a simulation of star life from birth through death. Players proceed around the outer track collecting mass and time to apply to their stars. Three stars are born in the stellar nursery and proceed through each of their life stages until they meet their final destiny a white dwarf, neutron star, or black hole! Questions have been written at four levels of ability, so the game may be used for B and C Division participants to prepare for the Stellar Evolution requirement in both the Reach for the Stars and Astronomy events.

Volcanism Volcanism on Planets Lots of worlds are thought to have volcanoes and volcanic features. However, the only known volcanoes are on Earth and Io, because we have seen them erupt. The Moon, Venus, Mars, and Mercury all have landforms that look like they were produced by volcanism, but we can not know for sure because we have not seen it happen live on camera. The movie to the left shows lava erupting out of the Earth and flowing downhill. The image to the right is an eruption of the volcano Tvashtar on Jupiter's moon Io. It is one of the first high resolution images we have of live volcanic activity on a world other than Earth. Volcanic eruptions can be massive explosions or large runs of liquid lava or small pimples that hiccup gas. What causes volcanoes to be so different? Lava Flows The shape of a volcano can be controlled by how gooey the magma is (a property called viscosity). Magma is made of liquid silica and some other elements. Magma that is poor in silica is called basalt, which is very runny. Magma that is rich in silica is called granite which is very sticky. Runny magmas can erupt to make long lava flows, while sticky ones cannot move very far and so pile up to make domes. The Earth has both types, because Earth has plate tectonics to make sticky granites. However, other worlds don't have plate tectonics so they only have the runny basaltic kinds of lava. The Moon, Mars and Venus all have long lava flows so their volcanoes are much flatter-looking than those on Earth.
