Aliens: The Hubble Space Telescope

“classified Hubble as a Cassegrain reflector, who was among the first to suggest a basic optical design.”1 The Hubble space telescope was launched and deployed in April of 1990, which “marked the most significant advance in astronomy since Galileo's telescope. Thanks to four servicing missions and more than 25 years of operation, the view of the universe and humanity's place within it has never been the same.” 2 In describing how

NASA has been around for 50 years, and they already sent over 200 missions into space. Each mission has its own discoveries and its own flaws. They all changed the way we look at our solar system, galaxy, and the universe. Some of them were successful and some were not. These missions have helped NASA a lot. Curiosity, Apollo 11, and Hubble have helped the world by discovering new things, making spinoffs, and successfully completing their mission.

With the announcement in 1996 by a team of scientists that a meteorite from Mars contained what might be the residue of ancient microbes, public interest became regalvanized by the possibility of past or present life there. The climate of Mars changes over time. “Mars Science Laboratory (MSL) mission will determine Mars' climate change over time for the lower and upper atmosphere. The mission will allow scientists to determine more precisely the composition of the Martian atmosphere. Mars Science Laboratory (MSL) mission will investigate the composition of rocks, soils, and land forms that might be linked with changes in the planet's atmosphere over time. (NASA) The key to understanding whether life could have evolved on Mars, many scientists believe, is water. (NASA) Other than water, there are many elements required to support life. For example, suitable climate, temperature, atmosphere and more, are conditions necessary for life on Mars, as important as water. After Earth, Mars has the most habitable climate for living in the solar system. Geologic features of Mars are collected by the Curiosity rover and studied by scientists. For instance, to find out has liquid water ever flowed on the surface of Mars and what caused the climate change on Mars. Of course, there are more environmental conditions affect Mars that lead scientists to further explore the natural environment of

Before the sailor flybys in the 1960s, scientist thought Mars had water and life, even if it was just some sort of plantlike lichen. Mars has water, frozen underground and at the polar caps. There is (event(s) or object(s) that prove something) that this water has, in the past and present, flooded the surface in liquid from. Signs of wearing away can be

Was there ever water on its surface? Will we find life there? Answers to these questions and others will come from studying and traveling to Mars. ”(Bowers, 1) We only know/see 4% (we only see 4 out of every 100 stars, planets and galaxies) of what is out there in space and we would learn so much more about planets and long-term space travel if we went to Mars because a normal rocket would be too small to be in for about 6 months. We would need to advance in the technology to colonize another planet and we would need to advance in our technology for long-term space travel.

Preview Statement: The possibility of life on mars is an extravagant topic to look at. Before that, we must analyze Mars itself along with its conditions. First, we will talk about the ice caps located on Mars. Second, we will examine the water streaks on Mars. Third we will observe if the red planet is inhabitable for humans to conquer it.

Space was so mysterious and frightening for thousands who dared to look up at the heavens. Many dared to wonder about what actually lurked and waited for mankind. Eventually man took the steps necessary to take the final leap into the unknown. Throughout history NASA has contributed to several extraordinary feats of science and space exploration from the moon landing to the Curiosity rover NASA has been vital to finding cosmic knowledge for mankind.

Its thin atmosphere and most likely a completely waterless surface shows that any life that was to land on the Red Planet would have a hard time trying to survive. At that time, when life was found on Earth, Mars had an ocean, volcanoes and deltas, the difference between Mars and Earth is Mars rapidly lost its hold on habitability. According to scientist Mars lacks the ability to have a protective magnetic field, most of the water left the surface and escaped into space, this was caused by the exposure of the surface to the cosmic rays and ultraviolet light. There were only a few packs of water left on the surface, some remained at the poles whereas others may have remained under the

Most astronomers and scientists seem firmly convinced of this fact. Although there is not any direct (or even indirect) evidence to support these claims that other sentient life is sharing the universe with us. However, this lack of evidence showing that extraterrestrial life forms exist is not proof that they do not exist. It just does not seem logical that our planet is the only place where life and intelligence could have developed. The odds are billions against life of some form being unique to the Earth only. The Earth is unimportant in the grand scale of things in the galaxy. By this I am referring to its' size and position in the universe. In fact, the American Association for the Advancement of Science suggests that the true question that we should be

Current geological indicators suggest that parts of Earth’s crust had already solidified by 4.4 billion years ago, which is not long before oxygen started showing up in ancient rocks. Furthermore, other microfossils (or chemical evidence suggesting their presence) have been discovered in the past year by research scientists, and possibly date as far back as 4.28 billion years ago.

gunter wachtershauser started it in 1988. proposed that a biochemical cycle grew and assembled the first living cell. swarms of bacteria rely on hydrothermal vents to thrive on the bacteria thrive on gases produced by the vents such as methane and use these chemicals to produce simple organic molecules to support the ecosystem. put ammonia, acetic acids, water, and salt to one container, and heated CaCO3 and zinc in another container to create carbon monoxide, which flowed into the first container. what came out was lipids and a drop in pH.

For whatever reason, the planet Mars has always been synonymous with alien life in popular culture. This makes it very interesting to study. Recent studies have taught us a great deal about Mars’ surface, water content and geography as well as suggesting that it may have been capable of supporting life in the past. Further study of Mars’ ice caps, various impact craters and other sources has helped scientists glean information of the planet’s history and the wealth of information that can be gained from its study. Of course, the most popular topic about Mars is its present habitability and presence of life, both of which are still very possible. Mars will be an excellent planet to analyze due to its proximity to earth and its ability to potentially sustain life.

Earth as known today is just temporally. The planet is always changing and once it was far different than it is now, it was an extreme habitat when life first appeared. The first fossil confirming life existence dates from 3.5 billion years ago [8]. However, the characteristics of this fossil indicate it was an organism reasonably evolved, suggesting that life appeared much prior in time. Even at present days is still hard to determine when the first life form appeared on Earth, since rocks older than approximately 3.5 Ga have been

Some conspiracy theorists claim that there have been in the past and currently are civilizations on Mars. There is said to be human-like extraterrestrials who inhabited the planet long ago and have used Mars as a base for some time. People point out that there are many underground tunnels and cities on Mars, similar to Earth, where these beings are said to live.
