MadSci Network : Astronomy Subject: Other worlds where H2S serves in place of H20? Date: Sun Apr 11 12:26:28 1999 Posted by Jackson McConnell Grade level: nonaligned School: Another Suffering Computer Programmer City: Windy City State/Province: Il Country: USA Area of science: Astronomy ID: 923851588.As Message: I saw a show on NOVA a few nights ago about bacteria that use hydrogen sulfide in place of water for (what I perceived as) their endpoint of electron transport. This idea fascinated me.. Is it possible that on distant worlds there could be conditions favoring H2S oceans, icebergs, rainstorms and dark sulfurous clouds? I seem to recall that one of the Jovian moons had a lot of sulfur on it. How different would such an environment have to be from the Earth to allow H2S to function in the role of water? Thanks for providing this service! - J. Re: Other worlds where H2S serves in place of H20?

Radio Interference Radio astronomer search for "faint" radio static from cosmic objects. Increasingly, the signals they are searching for are lost in the "din" of terrestrial radio communications, particularly the requirements of cellular phones and other modern communications using satellites. Major political battles loom as the demands of business clash with the need to protect certain important channels for radio astronomy. Readings Carpenter, S.

Perhaps volcanos like this occur on other worlds as well. http://www.adlerplanetarium.org/learn/planets/planetary_geology/volcanism.ssi

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.

Scriptual References to Astronomy by Erich Robert Paul Latter-day Saint scriptures indicate that both biblical and latter-day prophets and seers were shown visions of the heavenly realms to orient them to God's dominion and eternal purposes. These visions gave information about (1) the governing of systems of worlds and stellar objects; (2) a heliocentric, planetary cosmology; (3) the plurality of worlds; (4) the spiritual and physical creation of the earth and the universe; and (5) the role of Jesus Christ as creator. In contrast to some interpretations of biblical scholars who attribute a geocentric cosmology to the words of Joshua (10:12-14), Job (9:6-7), Isaiah (38:7-8), and other Old Testament passages, the Book of Mormon affirms the sun-centered (heliocentric) view accepted by modern planetary physics. The prophets Nephi 2 (Hel. 12:13-15) and Alma 2 agree that "surely it is the earth that moveth and not the sun" (Alma 30:44). Psalm 8:3-4 has been the classic text for discussion of the "plurality of worlds." LDS scriptures give even more direct support for modern astronomers' search for extraterrestrial intelligence. The prophets Enoch, Moses, and Joseph Smith all received revelations dealing with the existence of sentient life on other planets. Moses revealed both the spatial and temporal existence of countless worlds: that God had created "worlds without number," that "many worlds…. have [already] passed away," and that other worlds are yet to be created (Moses 1:33-38). Joseph Smith received

This dramatic revision has refocused Mike Seeds teaching philosophy to craft a book that strives to show students what they are and how we know What we are means our place in the cosmos. Mike explains that he wants his own students to do more than just memorize a list of facts for the final exam. He wants them to understand as astronomers do what humanity is. "We live on the surface of a rocky world orbiting a humdrum star in a universe of evolving galaxies. The students need to understand what that means to them and to their lives." The 6th edition of Foundations of Astronomy focuses on helping students understand their place in the universe their physical place and their temporal place in an evolving universe that had a beginning. How we know means how science works.

Continued Astrophysics Theoretical Astrophysics is the discipline that seeks to explain the phenomena observed by astronomers in physical terms. With this purpose, theoretical astrophysicists create and evaluate models to reproduce and predict the observations. Theoretical astrophysicists use a wide variety of tools which include analytical models (for example, polytropes to approximate the behaviors of a star) and computational numerical simulations. Each has some advantages. Analytical models of a process are generally better for giving you insight into the heart of what is going on. Numerical models can reveal the existence of phenomenon and effects that you would not otherwise see.

Sri Lanka: Gateway to Other Worlds? Scientists re-examine legends of Serendip O ngoing space research shares much in common with recent investigations studying the basis for Lanka’s ancient reputation as a gateway between worlds. The implications, researchers say, could be enormous. This article was written to commemorate Sri Lanka’s contribution to worldwide functions marking 1992 as the International Space Year. Patrick Harrigan , M.A., studied astronomy at the University of Michigan before entering the field of South Asia studies. He now serves as acting editor of the Kataragama Research Publications Project. Ptolemy's map of Taprobane. "Not only is the universe more complex than we ever thought, it is far more mysterious and magical than we ever believed." - American physicist Dr. Fred Alan Wolf Sadkona Yantra I nstantaneous transport between worlds , once the stuff of science fiction and long a favorite theme of lore and legend would ever dare to imagine, according to a growing consensus of researchers in the rapidly-emerging field of parallel universe theory. Now scientific interest appears to be focusing upon Sri Lanka’s living tradition of cosmography or sacred geography the understanding of which could lead to discoveries that are literally out of this world. Theoretical physicists, backed by recent findings in the field of radio astronomy, are suggesting that the visible universe as we see it may in fact consist of multiple overlapping universes that are dependently inter-related in some yet unknown way. They point, for instance, to recent calculations indicating that nine-tenths of the universe’s postulated mass may consist of 'dark matter' that is yet undetected and unaccounted for a disturbing fact to astrophysicists that is neatly explainable in terms of parallel universe theory.

E-Mail Me +++ Astronomy +++ You may think astronomy is boring, but you're wrong! Very wrong! Astronomy is all about space and the universe. It is very interesting stuff. Astronomy tells you how we came into existence and when and what will happen to our planet in the future. It helps us to understand our existence and the world around us. We can see if there are other life forms in the universe. We can learn about other planets and stars etc. There is so much matter in the universe, planets, stars, galaxies, moons, supernovae, nebulae, black holes and many more things. Basically astronomy is the study of the universe. Astronomers are scientists who study it. They try to answer all those questions that are on everybody's minds. They study the universe, they see how it was created, see how it will end, see if aliens live on other worlds and they find out all they can about other celestial objects. To answer these questions they can send space probes into space to monitor planets, asteroids, comets and moons etc. Astronomers can also use telescopes and observatories to look at the heavens. In addition, they can send humans (astronauts) into space to study it, live up there for a few months and even go to other worlds although the Moon is the furthest any human has been so far. We live on a planet called Earth. It is the only one found so far that supports life. It orbits a star called the Sun which gives us heat, light and energy. Earth takes 365.25 days to orbit the Sun. This is a year. The Earth also rotates on its axis. It rotates anticlockwise on its axis. It takes 23 hours 56 minutes 4 seconds to do this but as it is rotating on its axis and orbiting the Sun at the same time, a day is 24 hours long. This rotation gives us day and night. The side facing the Sun is in sunlight so it is day and the other side (which is facing away from the Sun - so no light is getting to it) is night. The Earth is also tilted on its axis at an angle of 23.5
