Extraterrestrial Life Or Alien Life

NASA discovered a system of seven Earth-size planets around a single star outside our solar system. All of these seven rocky planets could have water which is a key to life and three of them are firmly located in the habitable zone. This system is about 40 light-years (235 trillion miles) from Earth. Because of locating outside of our solar system, these planets are scientifically known as exoplanets. This exoplanet system is called TRAPPIST-1, name of telescope in Chile. Researchers using TRAPPIST announced they had discovered three planets in the system and then discovered more to seven by several ground-based telescopes. Moreover, NASA used data from Spitzer to measure the sizes of the seven planets and estimates the masses and density of six of them. The data indicated that they are likely to be rocky and could have liquid water on their surfaces but the mass of the seventh has not been estimated yet. Scientists assumed it could be an icy like snowball world. The temperature of TRAPPIST-1 star is cooler than our sun,

Astronomers at the University of Auckland claim that there are approximately 100 billion planets in the Milky way that mirror the conditions of Earth, making them habitable and giving them the ability to support life. For a planet to be considered habitable, it must be a comfortable distance away from a star, it must rotate on its axis and revolve, and it must have the ability to sustain an atmosphere. With 100 billion planets in our galaxy sharing these strict characteristics, it is unreasonable to assume that Earth is the only planet that holds

Today, we know that there are literally thousands, if not millions of other planets, many of which may be very similar to our own earth. In Philips Lewis article, "Do Aliens Exist? Here's What Scientists Say About Life on Other Planets", a notable astronomer created an equation that was able to "[e]stimate the likelihood of the existence of alien life, taking into account a number of factors including the average number of planets able to support life and the fraction that could go on to support intelligent life". Therefore, the chances of life and habitable planets in our galaxy alone is overwhelmingly high. Also, everyday scientists find more planets within galaxies, which adds more probability of some sort of life outside our solar system. Astronomers using NASA’s Kepler space telescope announced that the planet-hunting spacecraft had increased its catalog by an additional 1,284 worlds. “Planet candidates can be thought of like bread crumbs"

With all our knowledge of everything around us, overwhelming as it may be, there are still a lot of aspects that are unknown to even the smartest scientists. Did you know that humans know only 5% of the entire universe? Yes, everything we know about the Earth, the Milky Way, and all the planets is barely even a fourth of what comprises the entirety of the universe. Knowing that, it would be illogical to say that the creatures on Earth are the only forms of life in the universe. Today I will tell you about unidentified object sightings, close

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

We live in a universe that is about 46 billion light years old. In a world, as massive as ours there must be some form of extraterrestrial life out in the galaxy. For thousands of years ancient peoples, such as the Greeks, have wondered the same question. Are we alone? As our technology advances, things such as videos and photographs are surfacing of people claiming to see such alien life. Whether it is an unidentified flying object, or if it’s from someone claiming to see an actual alien, there are thousands of people that believe they have seen proof. Some also claim that the government is hiding things behind our backs, like the Roswell UFO incident for example. Though many people refuse to believe in the existence of alien life forms until they see evidence, the fact that multitudes of people have eye-witness accounts, the improbability that we are alone, and the idea that we have thought of aliens so long, bring forth the evidence that proves something is out there.

Among the billions of stars in each galaxy, many have planets that revolve around them. At least a few are bound to be of the right size and have the correct spatial orientation with respect to their star to allow life to grow. We believe this because life exists on the Earth. Astronomers have concluded that there must be hundreds of billions of other stars with conditions approximating those of the sun. Therefore there could be a million earth like planets with advanced civilizations in the Milky Way galaxy alone (Stilley). It is very probable that there is intelligent life elsewhere in the universe.

In this article, it states that 39 light-years away from Earth, there is a belief that science has found a new solar system. That very solar system is special since it has seven planets that are very alike to our Earth. With the terrain being rocky and warm enough that it could support life on it. This discovery is the first time people have ever found that out that there are rocky planets that are orbiting a single star. Before we have the technology we have today, the only terrestrial planets we knew of being four planets. And we didn’t even know much about our solar system, other than our planet and some a few others, but as we reach a new age in our world so many other windows are opening to us as a society.

The ongoing wonder on whether or not extraterrestrial life exists is not going to go away after this news. UFO researchers unveiled yet another NASA image of the sun that they claim is a spacecraft. However, NASA, who usually never comments on this kind if stuff, talked a little bit about the supposedly new discovery.

4 of the planets are in the habitable zone, meaning they could potentially support life. Meanwhile we have a planet that could have had life right here in our own solar system,“But the discovery that liquid water was once present on the Martian surface means, in Bortman's view, that living organisms might have been there, too.” (“There may have been”). The fact that mars may have held life is incredible, and realistic, after all where there is water there is life.“What the evidence does indicate, though, is that Mars was once a habitable world” (“There may have been”) which goes to show that while we don't have any specimen to examine, we can look at the facts and see that life did exist a one point in

The reason why astronomers never saw another life beyond the stars wasn't because there wasn't any it's because there were too many. As their history goes the Celestials are a race that has assembled other begins around the universe to correct its mistakes, and apparently humans are a big one. They set up shop on Mars, Saturn, Jupiter, Neptune, and

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.

I don't know why you guys are so obsessed with finding aliens. It's not like we are going to make contact with Extraterrestrials, at least in our lifetime. Over 500 Exo-Planets discover and not a single of them contains alien life.

There have been many sightings and abductions with aliens and UFO’s and there is many more to come within the next decades. Do you believe that aliens exist? Because if we don't think that there's another life form of some sort,we’re very small-minded people, because in a galaxy this big there has to be more than one type of life out there. Evidence suggests that aliens do exist.

One thing about this article is that it was written a little over nine years ago and much of our technology has improved since then. This means that the indirect proof that they were talking about is now advancing towards direct proof because many more signs of life on other planets have been discovered. More proof that our technology is improving is that not only was TRAPPIST-1 recently discovered there's also been other discoveries of planets suitable for life outside of our galaxy. One of these planets is called Kepler 186 which is in yet another galaxy and may also have water. Some other planets and moons that the article talked about such as Jupiter’s moon, Europa, Mars and maybe even Venus could have water. One final new source called Earth Guide, 2002, talks about two moons that may have signs of life. The article focuses on how many people only talk about there being life on other planets, this brings up the fact that there may be life on certain moons as well. The two moons that this article claims may have life are called Europa and Titan. Jupiter has 67 moons and Europa is the smallest of Jupiter's four largest moons. One of the reasons why the moon, Europa causes so much attention is mainly because it is so strange. What makes it so strange is that Europa may have liquid water many sources
