Pros And Cons Of Gravitational Microlensing

226 Words1 Page

Rouge planets, planets that are not tethered to a star and are therefore able to roam freely, are estimated to exist in the billions, and that is just in the Milky Way galaxy (Drake, 2014). Currently not all scientists believe that such planets are real, but evidence for their existence continues to grow. It seems it may only be a matter of time before they are considered as a scientific fact. There are several indirect methods for locating rouge planets. The two best methods are infrared observation and gravitational microlensing. Infrared observation works best for tracking relatively newer planets that give off more heat. Gravitational involves microlensing on the other hand works better for cooler planets. Gravitational microlensing involves

    Since the late 1940’s hundreds of people have reported seeing mysterious green balls of light in the night sky, particularly over the state of New Mexico in the U.S. The military decided to investigate the matter further as the objects often appeared over military and research installations. They launched Project Twinkle in December 1949 to study the balls in hopes of identifying them. At first the research seemed to indicate that the balls were artificial, perhaps even some sort of Soviet surveillance, but after two years the project was shut down and it was announced that the balls had been identified as natural phenomenon.

    The Keplerian Telescope: image source The Keplerian telescope has two lenses, both the objective and eyepiece lenses are convex (converging). When light parallel to the principal axis passes through the objective lens, the rays refract and converge until they hit the focal point. After they pass the focal point, the rays start to diverge. The rays are then intercepted by the eyepiece lens where the light refracts as it passes through the lens and causes the light rays to become parallel again as discussed in Converging Lens.

    Habitable planets are scarce but one will be filled with hope as it will become a home for the human race for millenniums to come; for now it seems Proxima b will have that honor. One of the most historic tools for space-bound research, the telescope is making astronomical bounds in assistance of astronomy research. The Hubble telescope is without a doubt the most influential telescope of all time. While not being the most powerful piece of equipment engineering has to offer, it has played the largest role of any telescope. “The Hubble Space Telescope is not the most prolific exoplanet hunter at astronomers ' disposal, but it has made unique and significant contributions to the discovery and study of dozens of far-off worlds.

    In almost all cases, they are too far away to be seen by a telescope. Two notable methods used to detect exoplanets are the Doppler Method and Transit Method. Doppler Shift Method The doppler shift method works by analysing the doppler effect that occurs when a planet orbits its star. The doppler effect is when a small mass, such as a planet orbits around a larger mass, such as its star, which will cause a shift or wobble as both masses have a gravitational pull towards each other, thus they will both orbit a common central point.

    Gravitational lensing can enable scientists to spot some pretty cool things, but so far, what they observed around the lens has remained fairly static. In another interesting observation, NASA’s Kepler telescope caught sight of a dead star, known as a white dwarf, orbiting a red dwarf in a binary system, Although, the white dwarf is heavier, it has a far smaller radius compared to its companion. According to Avi Shporer of California Institute of Technology, the technique is similar to spotting a flea on a light bulb 3,000 miles away which is approximately the distance from Log Angeles to New York

    For many years, it has been believed and scientifically proven that only the planet Earth can sustain life. And without it, we’ll no longer have a place to call home. However, with the Earth’s drastic condition - climate change, greenhouse gases, depletion of the ozone layer, and etc.- the astronomers have been searching for a planet that can save us from the ultimate fate of the Earth- and to also prove that we are not alone. Thus, after long years of research, we have found Kepler-452b. Here is a gist of what has been discovered about Kepler-452b:

    Some types of exoplanets include; rocky planets that are typically earth-sized or smaller. Most of these rocky planets are found in tight orbits, close to their hosts suns. These planets are likely more similar to venus than to earth because of this. The most sought out kind of exoplanets are those that earth-like, a similar size to earth and a similar distance from its host star. These planets are the most likely to be able to host extraterrestrial life however, because they are smaller and further away from their host star, they are harder to find.

    The acting point between planets which stay in an orbit and the sun is the orbit. Also, the calculation of the orbit is that “The orbit is an ellipse with an eccentricity of about 0.017, so the distance to the sun at any given day would be: r = a(1-e*e)/(1+e cos(theta)).” (researchgate.net). There are eight planets in the orbit in total (there is another planet, but it doesn’t count as the planet in the orbit anymore). “The total mass of all eight planets is around 2.67 x 1027 kg.

    “Our current space activities are held back by a lack of compact, but powerful energy sources. On the surface of Earth, we sit at the bottom of a deep gravity well, and it takes enormous amounts of energy to get things into orbit” (Fernando). Why would Fernando’s statement not hold true for other planets? For hundreds of years scientists have been researching for the possibility of extraterrestrial life on other planets, but they have not found any life forms. While there are Earth-like planets, none of them have exactly what it takes for an intelligent life to develop and thrive.

Some believe that life exist and some don’t, others believe that it isn’t worth looking for. The facts we have discovered about our universe can help us decide whether or not life can exist anywhere other than Earth. Life on other planets is seen as impossible by some for many reasons.
