Abstract. “Astrobiology Is The Field Of Study Focused On

The new ability to see beyond the width of a singular strand of hair, allowed for a basis of medical advancements. One of the early uses of the microscope, unveiled the inner working of the mechanics of the circulatory system. This discovery simply fueled an interest into the microscopic field of biology. Scientists discovered cells and from there quantum physics opened a new branch of inquiry for experimentation, today. With the discovery of microscopic entities, provoked questioning of what other forms of life could exist. Expansion of space, meant that another planet could host organisms or cellular life forms. Spacecrafts are equipped with sensors and powerful microscopes. These additions represent the interest in discovering new life forms. Simply, the purpose of the telescope led the way to more invention and intellectual stimulation of

The possibility of life beyond Earth is a tantalizing idea long prompting our species to wonder if there are other worlds where life exists. As space technology advances, the chances of finding life on other planets are now greater than ever. With new technologies such as satellites and solar panels, scientists are able to expand their exploration farther into our solar system. In 1995, an astronomer named Michel Mayor together with Didier Queloz discovered 51 Pegasi b. This was truly an incredible discovery that rocked the science community. Pledges b, a wobbling star the size of our sun, was slowly approaching, and according to Mayor’s

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

Astronomers study the planets, stars, and other celestial objects to try to understand how the universe works. They also study things like collisions, black holes and other things that could potentially affect earth. Astronomers gain information about objects in space from telescopes, and satellites. They can also use mathematical equations to find the positions of planets and stars in our universe. These telescopes and satellites observe light reflected by things such as planets, meteors, or stars in space and use it to make observations. Then the Astronomers job is to collect and analyze the data observed.

Humans have been searching for a habitable extraterrestrial planet before Galileo even assembled the first telescope. Since then, we have identified 1030 extraterrestrial planets, but only an esteemed handful of these copious supply of planets would even permit the hardiest of bacteria and single-celled organisms, let alone intelligent life. Kepler-452b is one of the most speculated planets yet discovered because it orbits within the Goldilocks Zone, or the perfect distance from its star so that surface temperatures of the planet remain stable for liquid water, and thus for life. Given that it is 60% larger than earth, takes 385 days to orbit its star, Kelper-452b exhibits almost every desirable characteristic of a habitable planet. However, it is a jaw-dropping 6 billion years old, or 1.5 billion older that our own sun.

With New Horizon’s next target to be 2014 MU69, located outside of our Solar System in the Kuiper Belt, it is no doubt that we will reach further ends of our universe through advances in spacecraft technology. The chance to explore other galaxies and the possibility of finding life on other planets inches closer to becoming a reality. It’s possible that life elsewhere would be quite different, but learning about the nature of life on Earth can help us understand the possible characteristics of life on other worlds.

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?”

In the article called “Another Earth” by Alice Savage and David Wiece started with the sharing of the theory that life outside of Earth could exist. The author’s son thinks that it’s possible for other living being to exist and live on other planets, but the author had this theory as just a theory until the moment when scientist found a lot of planets that can potentially have live life on them. After that, he starts to share his memories about what people thought about life outside of Earth back in the 70’s. He shares this idea that to find a planet we have to look at stars. He talks about two methods of how we can find a planet looking at a star. Planets have their gravitational pull and when they are moving around a star we can see them

Attention-getter: Have you ever just gazed at the night sky and looked at the stars and thought to yourself “Is there life on other planets such as, Mars?” Then, you begin to think if NASA will hire you after you applied 20 years ago.

    Including information comes from ‘Planets Are Close Enough For Atmospheric Studies.” Information for this comes from paragraph one, it states that “For years, scientists have found evidence that our galaxy, the Milky Way, is full of Earth-like planets. However, the TRAPPIST-₁ researchers say this solar system is our best target yet to search for life outside of Earth.” This quote explains that for much of our life we only

To begin with, there is more than one sun out there in space, and a sun can contain about one million planets in space. Scientists have discovered about one thousand planets orbiting distant stars. They have much more to discover! There is a big possibility that in one of those planets life could exist. Another big clue that scientist have discovered is that there are many galaxies in space and we live in one. The galaxy that Earth is located at is called the Milky Way Galaxy. A galaxy can contain many planets just like our galaxy can contains over billions of planets.

the ted-ed video “should we be looking for life elsewhere in the universe” summarizes that we should look. If we go explore we could find lots of new stuff( weapons,food,etc).there could be knew worlds beyond the solar system. NASA has good paying job for people.

According to NASA’s research on aliens and life outside of Earth, the main idea of their research is to travel to distant planets in search for signs of life. NASA has done many projects and conducted a lot of research regarding this topic. One of the projects that they have done is send a rover named Curiosity to Mars. This rover was sent there to collect data, pictures, and any sign of life. Some of the things that the rover found were strange writing on rocks as well as tall rock structures that resembled Mayan sculptures. Other experiments that they have done are evaluating the atmosphere on other planets and comparing them to Earth. The point of this is to see if these certain planets are suitable for life or not. In the diagram, it shows

Here we have three rudimentary questions: How does life begin and evolve? Is there life beyond Earth and, if so, how can it be identified? What is the eventual future of life on Earth and in the universe? Astrobiology confronts these riveting mysteries by putting practical use into the study of the origin, evolution, distribution, and future of life in the universe. An astrobiologist is known as a person who researches the possibility of life beyond planet Earth. Astrobiologists attempt to comprehend how life originates and how life manages to survive various types of environments. Usually, an astrobiologist specializes in biology as well as astronomy. Research in the fairly new field of astrobiology has an important influence on how agencies

The most common star is the M dwarfs which has the lowest mass, the lowest luminousity and the longest main sequence lifetime (at a few hundred gigayears). However this low luminousity means the oplanets need to be close to them.
