A star that goes by the name of Trappist 1 (named after the small telescope in Chile TRAnsiting Planets and PlanetesImals Small Telescope–South)has orbiting planets in the constellation Aquarius. Trappist 1 is about 40 light years away from Earth and is 12 times less the size of the sun but only a little bit bigger than Jupiter. Out of these seven planets, three of them are best suited for life. These planets are part of the Goldilocks Zone, they have the right amount of energy from their host star that oceans could exist. A group of astronomers found these planets by using a method called the transit method of planetary detection.
Four images of the quasar show up around the galaxy due to the intense gravity of the galaxy that bends the light coming from the quasar. 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
The refractor telescope has many advantages and disadvantages. One of the disadvantages is that the lenses are made of glasses therefore it has to be perfect with no air bubbles or scratches in the glass as this will impair the users viewing. Another disadvantage is that lense are weakest around the edges because they are thinnest there and that is the only place they are being supported by the telescope so this can lead to easy breakage. The lense can have colour distortion which means when white light goes through the lense it is split into colours. Since violet right is refracted more than red, the violet is brought to a focus clearer and this will make the image coloured and blurred, this is called chromatic aberration.
Science is used in the development of the film or special paper so that the pictures are able to develop fully and properly. Light is an electromagnetic energy. What is an electromagnetic energy? An electromagnetic energy is a form of energy that is reflected or released from objects in the form of electrical and magnetic waves that can travel through space. Light travels in a straight line and when it comes in contact with an object, it is able to be reflected, angled away, or even absorbed.
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. It is most effective when looking at larger planets that are orbiting nearer to its star.
Electromagnetic radiation can be an alternative medicine, especially since procedures involving these radiation are non-invasive. This essay explains how electromagnetic radiation is used in biomedical engineering, and describes how the procedures are performed. It also outlines the disadvantages of using electromagnetic radiation. Electromagnetic radiation was first discovered in the early 19th century. William Herschel discovered infrared radiation, and Johann Wilhelm Ritter discovered ultraviolet.
Introduction: In this lab, we measured the angular velocity of the sun (how fast the sun rotates on its axis) to find the time it takes for the sun to make a complete orbit. We did this by printing two images of the sun that are 7 days apart from NASA’s SOHO database to observe and measure one sunspot (the same sunspot in different locations on both images). We looked at sunspots because its dark (due to magnetic activity and heat transfer) and easy to identify since there are few spots from a faraway perspective. were able to solve for the time period it takes for the sun to rotate on its axis using the following formulas: θ=sin〖x/(R ')〗 where R’ is the radius of the circle the sunspot orbits, 〖θ=sin〗〖x/R_sun 〗 , where R_sun is the radius
The different gravitational pulls of the four types of stars show the different effects on space-time. The first star is our star in th center of the solar system referred to as the sun. The last star is a neutron star. Neutron stars are extremely dense star with a gravitational pull of two hundred billion times that of Earth. If a person lived on the sun in the center of our solar systems, and then traveled to a neutron star and lived there for one year, when the person went back to the sun he left, hundreds of years would have passed.
The Earth has been in existence for over four billion years, and the universe for much longer, but modern humans have only existed for approximately two-hundred thousand years. Since the beginning of human thought, people have looked to the sky and wondered what lay beyond what we can see. With the advancement of the human mind along with technology, the perception of the cosmos has drastically changed over time. One of the most important changes in our thinking was the Copernican Revolution, when Copernicus aimed to replace Ptolemy’s earth-centred model of the solar system with a sun-centred one. The advancement of science facilitated the changes in our perception, and it can be argued that our knowledge about the universe is getting closer
It is a gas giant, 96% of its volume is hydrogen. Saturn has been known since prehistoric times. Greek god Saturn was named after the planet, and ancient Chinese and Japanese culture named Saturn the “earth star”, one of the five elements of nature. Observations of Saturn from a telescope was first discovered by Galileo in 1610, with a 15mm diameter telescope. First photograph of the planet was in September 1979, by Pioneer 11, launched by NASA.
