Astrobiology Research Paper

Throughout history humanity has been fascinated by the existence of extraterrestrial life. Today such ventures are in the development process and the discovery of life beyond our solar system, no matter how primitive, may soon become a huge(important?) scientific breakthrough. The three basic things that are required to consider a place even remotely habitable are water, a source of energy, and organic materials. Habitability also depends on other factors that must also be taken into consideration such as how close the planet is to its star (in the case of our solar system, the sun), how long the water and organic materials existed there, and the size and mass of the planet. One must not confuse habitable with inhabited. The term

19. What is the scientific method, and how does it relate to the science of astronomy?

Stargazing is often thought to be something lovers would do on a date or something of a hobby. Astronomers and scientists of all kinds make their careers out of it every day.

Exobiology is the science that is concerned with the search for life in outer space; it may be called as astrobiology as well. The search for life in outer space has consumed the imagination of the humankind for long time ago. Nowadays, humankind has made a progress and found major discoveries in the quest for life existence in the universe and outer space because of the advancement of the technology. However, in the past, exobiology was considered as a science without a subject, where the people and other scientists laughed at and ridiculed the famous scientist and biologist Joshua Lederberg when he originated the term exobiology. Some people argue that life exists elsewhere in the universe, however, others believe that life only exist on Earth. A new study reveals that our galaxy, the Milky Way, has 100 billion or so stars, where 17 billion of them are Earth-size alien planets, and probably many more. The huge size of the galaxy increases the probability of life existence in the outer space. Are we alone in the universe? This question has captured the imaginations of scientist, theologians, and astrobiologists. However, they don’t know the answer yet. Understanding the complete definition of life and how life originated, and determining the techniques used for searching for life existence in outer space and evidences found can help to answer the question of “Are we alone in the universe?”

When fields of science are being discussed, most people are going to immediately think of fields like biology, chemistry, and physics. It is quite strange that these fields are the most popular. This is because biology, chemistry, and physics can be combined into one single field. That field would be astronomy. While most may think that astronomy is just viewing stars through a telescope, there is an immense amount of more complicated ideas associated with astronomy. What with the fastest speeds, highest masses, major chemical compositions, and even the idea of sustaining life, astronomy has to be one of the most complex fields of science. Without astronomy, many things about the life of humans on earth would be a mystery, not to mention where

Abstract: Scientists claim that other life forms do in fact exist based on probability. The conditions necessary for life are likely to be present on various other planets. Signs of possible life have been found in material from outer space. Much research has been dedicated to proving the existence of life on Mars. SETI is a program entirely dedicated to finding and establishing communication with extra terrestrials. If other life forms are found, communication with these beings will be a difficult task. Laws to protect humans from the dangers of extraterrestrial beings are already in effect. Although contact with alien beings has not yet been made, technology today may make it a reality in the near future.

I am contacting you on behalf of the Astronomy Club. As you may or may not have heard, the Associated Students of the University of Arizona released a statement to all of the clubs on campus saying that the Appropriations Board had a meeting on March 6th and concluded that it no longer had any more funds to support any of the clubs until further notice. We received this approximately 2 weeks prior to when we had planned to submit our necessary document to request travel funds for our upcoming 2-day trip to the Grand Canyon/Discovery Telescope on the weekend of April 14-16. Therefore, we are contacting you to ask if the department would consider partially funding this event.

My topic is going to be the great organization called NASA and about some of the mission’s they have done and some things you didn’t know about them. In my opinion I think that NASA is a very hard working Company that tells us all about what’s going on in our universe like when a solar eclipse is going to happen and stuff like that.

The thought that intelligent beings may exist somewhere in the universe other than the earth seems to fascinate certain people; therefore, for more than fifty-five years astronomers have listened for an indication of life from outer space. However, “E T” has been as silent as a tomb.

Liquid water is the most important factor for life, as we know it. Water is abundant in the galaxy, it is found in cold dense molecular stars as well as hot stellar atmospheres. Liquid water exists at a large range of pressures and temperature.

Scientists have been baffled by the existence of life on Earth where conditions have been thought to be uninhabitable. The existence of these extremophile species, organisms living in conditions thought to be unable to sustain life, on earth gives a boost to the possibility of outside life. Science also does not have a full grasp on exactly what conditions are necessary to cause life to bloom (McAlpine). Just because life is thought to only be able to thrive in certain conditions on Earth, does not mean extraterrestrial life is bound by the same rules, especially if terrestrial species are known to occasionally break the rules. Discovery of life existing away from planet Earth that does not meet the preceded notions of what life must be like would lead scientists to better understand how life functions and performs under countless situations and conditions. Space itself supports this as “we’ve discovered things such as oceans in places we thought they couldn’t exist” (Drake). Oceans on earth are home to millions of species and are hubs for aforementioned extremophile species, most of which remain unknown to modern science. Since oceans on Earth are teeming with mysterious undiscovered life, there is no telling what awaits at the bottom of deep space oceans. If scientists can understand how species may be able to thrive in previously thought to be unlivable conditions, scientists can use those discoveries to help humanity explore areas that would otherwise be perilous. Or perhaps, scientists could potentially use understandings of extraterrestrial life to help humanity form a second home among the

Astronomy is a science that studies everything outside of the earth's atmosphere, such as planets, stars, asteroids, galaxies; and the properties and relationships of those spiritual bodies. Astronomers base their studies on research and observation. Astrology, on the other hand, is the belief that the positioning of the stars and planets affect the way events occur on earth. If you're interested in the solar system and the planets, other celestial objects like asteroids and comets, other galaxies and the rest of the universe, what makes up space, and the possibility of alien life or space travel, astronomy is the field you're considering. Astronomy is a natural science that studies celestial objects and phenomena. It applies mathematics, physics, and chemistry, in an effort to explain the origin of those objects and phenomena and their evolution. Objects of interest include planets, moons, stars, galaxies, and comets; while the phenomena include supernova explosions, gamma ray bursts, and cosmic microwave background radiation. More generally, all astronomical phenomena that originate outside Earth's atmosphere are within the purview of astronomy. A related but distinct subject, physical cosmology, is concerned with the study of the Universe as a whole.

I have always had an interest in science, especially in the sciences regarding outer space. When I was younger I was always fascinated with rockets, and especially in stars. I have often regretted not pursuing this interest at its infancy. I do remember going to the Planetarium, and studying about a topic that I had seen talked about on television. The topic was black holes, and back then all that they knew was that they were black. The idea of a space in the universe that is completely void of light was difficult to imagine. Recently, I have learned more about this topic and a science call cosmology. I had never even heard of this field of science before I was introduced to a scientist by the name of
