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° ...

Galileo Galilei (1564-1642) was an Italian physicist, astronomer, philosopher, engineer and mathematician. He was a critical figure in the scientific revolution of the 17th century. Galileo is perhaps most synonymous with the invention of the modern telescope which has since helped man to discover countless things about the universe. In regard to astronomy, Galileo is erroneously credited with the discovery of the first telescope. His contribution was carrying out massive improvements on the existing telescopes. In 1609, Galileo learnt about the spyglass which was crudely used in ordinary life to view distant places on the land. Galileo began to ...

Introduction

It is very rarely that a story could have an effect on the reader. This is why I am thankful that I encountered Wendy Mass’ “Every Soul a Star.” As I read though the story, I was able to relate to the experiences of the main characters. Being a young person I also meet challenges where I need to change. The story gives its readers important insights on how important and inevitable change is. In the story, three young people went through life changing experiences in a place called Moon Shadow Campground.

The Moon Shadow Campground is a place ...

English astronomer W. Herschel discovered planetary nebulae in about 1783. Nebulae received the name "planetary" on account of their external similarity with the images of distant planets, light wheels of which are different from the point images of the stars. “A planetary nebula is a beautiful object created during the final stages of the life of a star whose birth mass was between 1 and 8 solar masses” (“Planetary Nebulae”). A planetary nebula is an astronomical object consisting of an ionized gas shell and the central star, a white dwarf. All planetary nebulae originate from stars that are in ...

Facts about the Earth

The Earth is the third planet from the Sun. It is situated at the distance of about 93 million miles from the parental star. The Earth`s orbit is elliptical. The Sun, the Moon as well as all the stars rise in the East and set in the West due to the rotation of the Earth around its axis. The Sun and the Moon moving together create the eclipse, when the Moon stands between the Earth and the Sun we see a solar eclipse, at that moment the Moon passes in front of the Sun obscuring it. In the ...

Many centuries ago, a man witnessed an apple fall from a tree and had a scientific revelation about the way that the objects on the earth worked. This was no ordinary man: this was Isaac Newton, and this incident would lead him to formulate the law of gravity. There are many variations and controversies about the apple story, including a conspiracy that Newton himself made it up. Regardless of the origins of the story, this scenario has become the symbol of Isaac Newton’s life and person in science classes around the world. In addition to his theories of ...

After seeing the pamphlet on “Ghostblasters,” a business dedicated to remove ghost from the home through a scientific process, it was important to explore how legitimate this claim is. Typically, there is not even proof of ghosts as an actual reality, but rather a myth to frighten young children. Here, there is business advertising and collecting money from individuals who seek their services believing there has been an “ectoplasmic” removal of the ghost materials. Not only has the proof of ghosts been inconclusive from a scientific point, but the possibility to remove something that has not even been proven ...

Introduction

In the last few centuries, our understanding of universe has grown by leaps and bounds. Before seventeenth century, people generally believed that the Earth is at centre of the universe and all heavenly bodies move around the Earth. Galileo challenged the idea and published his papers in support of Copernican heliocentric theory that the Earth and other planets move around the Sun. Our understanding of universe grew further. We realized that the Sun is not unique and there are hundreds of billions of stars in the galaxy, which are brighter ...

Modern astronomy

There were four main contributors to modern astronomy: Sir Isaac Newton, Johannes Kepler, Galileo Galilei, and Tycho Brahe. Brahe advocated for the new standards for having a more precise observation even though he did not personally believe in the view of heliocentric. All of his contributions were huge for astronomy because he was able to create new instruments along with being able to calibrate them. He would check the accuracy of his instruments on a regular basis so it helped him to revolutionize instruments for astronomy. Kepler was an assistant for Brahe until he died in 1601. This helped ...

A Supernova is typically the resultant of the explosion of a star. It occurs when a there is a change in the core or the center of a star. Supernovas burn only for s short period of time, but they enable scientists to discover many things about the universe. For instance, a kind of supernova has led them to discover that the universe is constantly expanding and growing and that too, exponentially. They also help to distribute elements all around the universe. It so happens that if a star explodes it throws out debris and star’s elements all ...
