Part 2. Recent and historical images of Mars

Historical Image of Mars. Website reference: http://www.fourthplanet.space/tag/christiaan-huygens/

Image info: Christiaan Huygens’ observational drawing of Mars shows a triangular feature which known today as Syrtis Major.

Telescope used: Huygens used a telescope created by himself (1655). It was a good 2-inch (5.1-cm) telescope of 10.5-foot (3.2-m) focal length and 50x magnification. (Sheehan)

Observer: Christiaan Huygens

Exposure time: Observations were taken over a number of weeks. Other relevant details: Huygens used results of his observations of Mars to measure Mars’ rotational period. He measured it as 24 hours (only one hour away from the rotational period of the planet recognized today). It should be noted that the most prominent and largest crater of the Mars was named after Huygens (14.0°S, 304.4° ...

The continental plate in the eastern part of Asia is composed of various volcanoes and tectonic movements. Most of the volcanic rocks in this region are composed of alkali basalts with signs of continental contamination. There are various models that explain the region’s magmatic evolution. The two most common models used to explain the movements refers to the surficial processes and the other one refers to the deeper processes associated with the Pacific ocean plate. These two processes are antithetic and may hay happen subsequently. The volcanism can be traced by tomographic imaging that can be directly associated ...

Nonfiction writing has always been a difficult task, considering the amount of effort it requires to study, analyze and research a particular area and then present a research in a concrete and standard way. Walter Alvarez has done a fabulous job in providing a base to the theory of extinction of dinosaurs some sixty-five million years ago. In the last few decades geologists have continuously debate over the existence and extinction of Dinosaurs and various theories including asteroid or comet, Tsunami and Volcanic Eruptions, however a definite answer was always missing.

“T.Rex and the Crater of Doom”, has been successful in tranquilizing the inquisitiveness of the ...
