Astrobiology: The Potential for Extraterrestrial Life Michael Russo Professor Nieter Science Inquiry: Geoscience Introduction Astrobiology is the area of study dealing with alien life‚ the likelihood of finding it‚ where it might be found‚ how it evolved‚ its morphology‚ its culture‚ etc. It’s a huge field that overlaps all the sciences but especially the geosciences‚ evolutionary biology‚ chemistry and bio-chemistry and astronomy. In the following report I focus on astrobiology as it

Christiaan Huygens was a Dutch scientist and mathematician born in 1629. Huygens was known for his work with early studies of the rings of Saturn and later the discovery of Saturn’s moon Titan. Huygens would grind his own lenses for his telescope and invented what is now known as the Huygenian eyepiece. He was also known for his work as a physicist‚ probabilist‚ and horologist. Placing two plano lenses in a telescope‚ separated by an air gap‚ creates the Huygenian eyepiece. The lenses should

Mars shares similarities with Earth: It is rocky‚ has mountains and valleys‚ and storm systems ranging from localized tornado-like dust devils to planet-engulfing dust storms. It snows on Mars. JUPITER • The fifth planet from the sun‚ Jupiter is huge and is the most massive planet in our solar system. It’s a mostly gaseous world‚ mostly hydrogen and helium. Its swirling clouds are colorful due to different types of trace gases. A big feature is the Great Red Spot‚

the 20th century. Neptune has been visited by only one spacecraft‚ Voyager 2‚ which flew by the planet on August 25‚ 1989. Neptune is similar in composition to Uranus‚ and both have compositions which differ from those of the larger gas giants‚ Jupiter and Saturn. Neptune’s atmosphere‚ while similar to Jupiter’s and Saturn’s in that it is composed primarily of hydrogen and helium‚ along with traces of hydrocarbons and possibly nitrogen‚ contains a higher proportion of "ices" such as water‚ ammonia

one of his own. In the fall of 1609 he began looking at the sky with a telescope that magnified up to 20 times‚ in December he drew the phases of the moon that he saw through the telescope. In January of 1610‚ he discovered four moons orbiting Jupiter( Jupiter has at least 69 moons). Galileo may have been the first person to look at the sky with a telescope‚ but not to invent the telescope.

information accumulated with the arrival of the Cassini–Huygens mission in 2004. Formation of Titan The moons of Jupiter and Saturn are thought to have formed through co-accretion‚ a similar process to that believed to have formed the planets in the Solar System. As the young gas giants formed‚ they were surrounded by discs of material that gradually coalesced into moons. However‚ whereas Jupiter possesses four large satellites in highly regular‚ planet-like orbits‚ Titan overwhelmingly dominates Saturn’s

asteroids. These are different chunks of rock‚ which range from specks of dust to those which are a few kilometres across. Most of them travel in an orbit between Mars and Jupiter called the asteroid belt. Others follow different orbits. In the 18th century‚ astronomers were convinced that a missing world existed between Mars and Jupiter. A search was mounted and the first asteroid‚ Ceres‚ was discovered by an Italian astronomer Giuseppe Piazzi in 1801. Today‚ over 5000 have been catalogued. Most asteroids

North America and part of the Atlantic Ocean will be in the sunlight. Earth will be visible as a pale blue dot and our Moon will appear as a colorless star-like point of light. Cassini will be in the shadow of Saturn and the senitive detectors will not be damaged

Greek and Roman Gods‚ Temples‚ and Festivals: Alike Yet Different by Rose Williams The following discussions are samples from an overall study which is used in my book ‘Gods and Other Odd Creatures.’ Drawings “Gate of Janus Geminus” and “Aedes Vestae”are from the book and may be copied‚ as may all other drawings in the book. Since the Romans were both polytheistic and tidy‚ they tended to organize the deities they encountered and to equate them to Roman gods if possible. Thus when they conquered

A day in a life of an astronaut I wake up because of the blinding light outside .The sun truly comes out like thunder I say to myself ‚each sunrise lasts only a few seconds ‚but in that time you see at least eight different bands of color come and go ‚from a brilliant red to the brightest and deepest blue. I see sixteen sunrises everyday here in space‚ but no sunrise or sunset is ever the same. I am still overwhelmed by the fact that I am one of the people who have been to space. I summon
