The article I chose was known as, 22% of Sun-like Celebrities have Earth-sized Planets in the Habitable Zone, by Nancy Atkinson, posted on universetoday. com on November 4, 2013. The article involved the number and the discovery of habitable Earth-sized planets. This topic have been pursued for many years, and finally we now have results, due to NASA Kepler spacecraft. In respect to Keplers data, a great one in five celebrities, about 22. 8%, inside our galaxy, like the Sun, have got planets similar to Earth that may theoretically (hypothetically) host lifestyle. The Habitable Zone, or maybe the Goldilocks Area, is in which a planet is usually neither too cold nor also hot to back up liquid drinking water. Erik Petigura, University of California, Berkeley graduate, who have leads the analysis (detailed examination) for the Kepler and Schmissig Observatory in Hawaii, responses, The nearest sun-like star with an Earth-size planet in the habitable area is probably just 12 lumination years apart, and can be viewed with the naked eye. That is certainly amazing.

The Keplers mission was to find planets with the prospect of hosting liquefied water and maybe the ingredients essential for biology (life) to take keep. The study was focused on G and E type celebrities. G and K type stars are main-sequence superstars that conduct nuclear fusion. K type stars happen to be slightly smaller and much cooler than G type celebrities. The Sun can be described as prime example of a G type celebrity. So far, all of the possible planets have K type celebrities, but scientists are sure there are usable planets with G type stars. In fact, we are living proof. Planet seeker Geoff Marcy says that they will be 8. almost eight billion Earth-size planets in the Milky Way. But this individual also says that not many of these planets will be habitable. “Some may include thick atmospheres, making it thus hot in the surface that DNA-like molecules would not survive. Others may have rugged surfaces that can harbor liquid water well suited for living microorganisms. We can’t say for sure what variety of planet types and their environments are suitable for lifestyle. ” And the search for one more place for humans to be in continues.

This post relates to that which we are learning in class mainly because we are studying astronomy, the sun, stars, and everything about it, which include Earth. Later on, we will also be learning about the Kingdoms of Life and exactly how life begins, and that straight relates to the main topic of the article. As well, the Kepler spacecraft and observatory had been named intended for the well known astronomer Johannes Kepler, and that we are researching famous astronomers like Kepler and Ptolemy, too. Additionally , the hunt for another planet that humans can go on is based off on avoiding any sort of disaster that could happen, like overpopulation, running out of all-natural resources, or perhaps the inevitable explosion of the Sun in 5 billion years. (Not we can avoid it on time. ) In the lecture, we often discuss subjects honestly.

This article is very interesting and stimulating. It told me just enough to generate me be familiar with topic, although not all of the details so that I would pursue the subject more. Problem: is there, or could there be, various other alien life, is a question people all over the world have got asked, not merely astronomers. From this aspect, this article is something that everybody, everywhere, may connect to. The sentences ran extremely well with each other, and the thoughts were saved with cement evidence and models. In my opinion, this article is one of the very best content articles out there today.
