ASTROPHYSICS Methods used to search for extrasolar planets Lucky Ruangsiri 24.02.2016 Extrasolar planets are planets that revolves another star apart from our solar system. The human race has found nearly 2000 confirmed extrasolar planets by the year 2016, and this has fuelled the search for extra-terrestrial life as we scour the universe for anything out there. How do we discover these planets that are light years away from the earth? An extrasolar planet detection technique is the Doppler technique, also known as the wobble method or the radial-velocity method. The influence of a planet’s gravitational pull on its parent star causes the star to wobble slightly, and this wobble influences the waves of light that a telescope can…
The Sci-Fi story I will be writing about is going to be about space mission to a habitable extrasolar planet. It will be based centuries into the future when technology has improved to the point that our human race can visit planets light years away. Of course there are still effects of long-term space travel on the human body, but the technology and research will be more advanced during the time period of my story. The mission is going to consist of highly trained astronauts and the most…
discovered. Extrasolar planets are defined as planets rotating around other stars- or remnants of stars. This is comparable to our planet rotating around the Sun. We have known for centuries that these other stars existed. Despite this, it wasn’t until the 1990’s that the first extrasolar planets were discovered (Bennett et al, 2016) In order to discover the planets, we must have ways of…
The Kepler Telescope main instrument is a photometer. This instrument measures the brightness of stars within its field of view. Data is then gathered and analyzed to detect any variations or deviations of light which is caused by the transits of plants of host stars. These dips in light help in detecting planets in "Habitable Zones". Gliese-581g The planet Gliese 581g is one of six possible planets in the constellation Libra. This exoplanet was discovered in late September 2010. The main reason…
research(although they are researching more planets similar to earth) because, it has many signs that it could sustain life one day! Some theories about NASA and the thought and evidence of life beyond earth surprisingly don’t have a lot to do with aliens(unless you specifically research that). In one’s opinion, one might say that there should and possibly is life beyond earth- we just don’t have the technology yet-to go so far into space to discover it. One of the main topics that could pop…
In this lab, the objective is to research astronomical devices through the provided respective links. After choosing one of the devices used to study Astronomy, the researcher must then begin to delve into information about the device and its current location and providers. Through research an understanding is gained, and the researcher is able to better comprehend the capabilities of their decided to device. Once this step is achieved, it is next part of the process to review images produce by…
UFOs, alien sightings, and abductions seem to come from science fiction novels since there is a lack of “actual” evidence. The beliefs of society are that aliens bring humans to their spaceships, do surgeries and bring them back to the ground miles away from the place of abduction. Are aliens real? If so then what do they want with us? Aliens are a mystery that only time and evidence can solve. Let me describe my experience when I recall getting abducted. As I got home from work, I saw a star or…
An exoplanet is described as a planet that orbits a star outside our solar system. The majority of the exoplanets scientists have discovered were found in the past two decades, mainly with the Kepler space telescope. These planets are all different in orbit, size, and type. Some are smaller than Jupiter, or even larger than Jupiter, but essentially all of the exoplanets that we know of a larger than the Earth. Scientists have even found planets that orbit two stars, as opposed to the normal one.…
Since the first planet orbiting a star other than our Sun was discovered almost 20 years ago, astronomers have detected over 3,000 exoplanets. Going forward, exoplanetary scientists have two major goals: detecting smaller, more Earth-like planets, and characterizing particular planets of interest. With the advent of the extremely large telescope (ELT) era soon approaching, these two goals will become increasingly intertwined as better instruments give us the power to study the atmospheres of…
Alien Vortex and Killer Sea Farts are alike and different in many ways. The articles explains some ideas about what the Bermuda Triangle is. The Bermuda Triangle is a body of water in the North Atlantic Ocean. This is not like any other bodies of water, The Bermuda Triangle is where many aircrafts and ships have randomly and mysteriously disappeared. Super natural events and methane gas are two theories of the Bermuda Triangle. The Alien Vortex talks about things other Killer Sea Farts. The…
