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. …show more content…
Until space industry can devise a transportation system faster than light-speed, humanity has no hope of ever exploring this planet. On more auspicious terms for discovering a habitable world, one does not need to look farther than our own solar system. Cassini, an orbiter of Saturn, discovered that one of its moons, dubbed as Enceladus, has liquid water beneath its icy crust. Furthermore, a rocky core at the bottom of the ocean confirms that the liquid water may have the essential minerals and nutrients to provide microbial organisms with a sustainable food
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
Erythropoietin-producing hepatocellular carcinoma (Eph) receptors, a group of highly conserved transmembrane proteins composed of multiple domains, participate in various cell signaling pathways. So far, 16 Eph receptors have been identified in vertebrates, which can be divided into two major classes (EphA and EphB) based on sequence similarity. Mammals including humans have 14 Eph receptors (EphA1–EphA8, EphA10, EphB1–EphB4 and EphB6).
It's time to experience high speed and frustration free internet browsing and home networking. The Belkin N750 (F9K1103) DB Gigabit Wireless N+ router is a well rounded and feature packed home network upgrade. Slow downloads, dropped connections and lagging game-play are all a thing of the past with the N750 from Belkin.
Marketing, sales, and service are three major areas that e-CRM’s should put most focus and value to for the total business package. Kudler needs to establish a formal business plan for the Frequent Shopper Program before inception of the e-CRM project. The plan requires a detailed outline that brings forth these elements pertaining to the compiled projected costs, tangible financial benefits, and intangible strategic benefits, also risk assessments for the project.
The conception of transparency seems to be everywhere in todays time, from the products we consume as buying customers to the governments we look to in leading our nations. Social media is another refuge for transparency. With millions of people noticing, it’s difficult for any organization or individual to say one thing and do another. Supporters of the transparency movement say that it is a very good thing; after all, transparency is serving to keep people honest and up front about the products and services they sell to consumers.
The exoplanet known as Kepler-453b is what is known as a circumbinary planet. A circumbinary planet is a planet that orbits two stars, and Kepler-453b is the tenth such planet discovered so far. It is a timely discovery not only because it was discovered at around the same time that news broke out of the world’s superpowers looking to make Star Wars a reality by waging war in space, but also because the real-life Tatooine was discovered by chance in a classic case of being in the right place at the right time.
So is GJ436b worth the journey to maybe become a second or alternative human home? With current technology, resources, and knowledge the answer is maybe. It is said that the surface may have rock and ice but with current technology it is difficult to tell. However, on May 16, 2007 scientists calculated that GJ436b’s diameter is 3.95 +/- 0.35 Earths diameter. These measurements allowed the scientists to deduce that the planet could sustain “exotic ice” based on size, mass and location relative to its star. In describing the location of GJ436b, it orbits its star at a distance of roughly 0.02887 (+/- 0.00095) AU. That amounts to less than a tenth of the distance between the Sun and Mercury in our solar system. This means that the surface temperature is very hot with scientific
Currently, there is only one planet we know of to host life, and that is our home planet Earth. The question remains as to what is exactly needed for a planet to be considered habitable, but scientists have developed a handful of criteria to help distinguish what planets could be “just right” for life. The ongoing search for possible habitable planets has produced many remarkable findings but nothing quite as extraordinary as the discovery of the system Trappist-1. According to nasa.gov, it is the first known system of seven Earth-size planets around a single star, and it meets the criteria to possibly sustain life (“NASA Telescope Reveals” p.1). This discovery poses a likely answer to the question “are we alone” and drives our search for finding out more about what is out there.
The topic of finding life on another planet, or seeing if we are the only ones in our Universe has been a mystery to us since the beginning of time. One of the closest findings NASA has found to this topic was exoplanets. Exoplanet is defined as a planet that orbits a star outside the solar system. NASA’s Kepler Space Telescope is the main telescope used to search for exoplanets that have similar features to Earth, and habitability on these exoplanets. NASA has found over 2,000 exoplanets so far, and out of those, there are only about eight exoplanets that seem to have a possibility on being a habitable exoplanets. Among these eight, Kepler 62f seems to be the most plausible.
NASA has already discovered a planet resembling Earth and even though the conditions for life to exist are quite precise, with the existence Earth-like planets and the universe being larger than the human brain can comprehend, the odds keep growing higher for life to exist somewhere out there amid the yet-unknown celestial bodies.
The centuries old quest maybe as old as NASA has been started for other words like our earth has been rejuvenated by the intense surrounding the discovery of hundreds of planets. The kepler mission, which is one of NASA’s best discovery missions it is specifically designed to survey our region of the Milky Way galaxy to discover hundreds of Earth-size and smaller planets in or near a habitable zone.
For a long time, it seemed the distant dwarf planet on the edges of our solar system could never contain life. The latest discovery by NASA however, just may change that assumption. Scientists have uncovered a large, underground ocean far beneath the frozen surface of Pluto.
Right alongside the fifth and largest planet in our solar system, Jupiter, orbits a moon only about the same size as Earth’s moon. On this moon, is an icy surface that scientists are trying to uncover. Due to the presence of what they believe to be water, there is the possibility of life on this moon named Europa.
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
We now focus our attention on the formation of one particular planet, one that is so far unlike any other in the universe, Earth.
