Rocky Planets Research Paper

NASA discovered a system of seven Earth-size planets around a single star outside our solar system. All of these seven rocky planets could have water which is a key to life and three of them are firmly located in the habitable zone. This system is about 40 light-years (235 trillion miles) from Earth. Because of locating outside of our solar system, these planets are scientifically known as exoplanets. This exoplanet system is called TRAPPIST-1, name of telescope in Chile. Researchers using TRAPPIST announced they had discovered three planets in the system and then discovered more to seven by several ground-based telescopes. Moreover, NASA used data from Spitzer to measure the sizes of the seven planets and estimates the masses and density of six of them. The data indicated that they are likely to be rocky and could have liquid water on their surfaces but the mass of the seventh has not been estimated yet. Scientists assumed it could be an icy like snowball world. The temperature of TRAPPIST-1 star is cooler than our sun,

The best technology available today for studying the chemical composition of stars and planets is spectroscopy, a scientific tool that dissects light into its component colours (Astronomy mag. P.31). “A planet within 100 light-years of Earth is close enough to provide sufficient light for scientists to dissect light into its component colors” (Ray Villard, Astronomy ). Spectrographs are used by astronomers to observe discrete spectra. Discrete spectra are produced by gases, such as … when specific wavelengths of light are absorbed or emitted by the gases. This causes dark bands to appear on the spectrum where the specific wavelengths of light are absent. A scientist can

The reading on terrestrial planets from chapter 6 provides readers with a little insight on the similarities and differences between the planets. These planets include Earth, Venus, Mercury, and Mars. Although these planets have very different properties, they are connected due to their history. There are scientific laws that help people understand, compare, and contrast these planets, such as gravity, chemical composition, and temperature.

In this paper I will explain how astronomers determine the composition, temperature, speed, and rotation rate of distant objects using various methods. I will explain the properties of stars. I will also summarize the complete lifecycle of the Sun and determine where the Sun is currently in its lifecycle.

Scientists have discovered a new planet that they believe may be capable of housing life. LHS 1140 b, the planet in question, is six times heavier than Earth, yet only 1.5 times as large, suggesting that it is an extremely dense ball of metal and rock. LHS 1140 b is ten times closer to its sun than Earth, as well, making the orbit only 25 days. The sun LHS 1140 b orbits, LHS 1140, is an old, dim red dwarf star, 40 light-years from Earth in the constellation Cetus. Everything about it is rather ordinary; red dwarfs are the most common type of star, and the light that LHS 1140 produces is too dim to be spotted with the naked eye.

These results are considered significant by the researchers in the article and by the scientific community in general because they provide some evidence for the fact that there are other sources of life in the universe. Additionally, these findings are important because they provide evidence that there are a number of "dynamically packed" (Billings) solar systems, in which the potential planets are huddled closely about their solar systems. This fact means that there may be a lot more planets in the universe than scientists were previously aware of (since they are grouped so closely together), which increases the possibility of additional life in the universe. Future research is needed to corroborate these initial findings

much a star wobbles or goes around the centre of gravity of the exoplanet and star, the violent wobbles must conclude that 51 Pegasi b is a Jupiter sized exoplanet. Hd209458 b is also a Jupiter sized exoplanet, which may have been determined using the calculation or the wobble method, having similar affects to its host stars light spectrum as 51 Pegasi b has on its host star. Astronomers are unsure whether the exoplanet named Kepler 22b is a larger Earth or more of a mini Neptune, as it is boarder line between a rocky planet and a gas dwarf.

This experiment was conducted to study and investigate if extraterrestrial life exists upon the exoplanet TRES 2. It was hypnotized that TRES 2 did not sustain the qualifications to support extraterrestrial existence. The results from this testing conclude the hypothesis was correct, with research as an addition from the luminosity testing it has been knowledge that TRES 2 reflects less than 1% of light making it one of the darkest exoplanets currently discovered. Light is a crucial element in the building blocks of life, it is the most important factor that influence the way life evolved on Earth. From photosynthesis, which is responsible for making producing nutrients in plantae’s and meeting our energy requirements. Furthermore TRES 2 orbits

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.

Findings revealed that the system is located 39 light years from the solar system and is in the constellation of Aquarius. The system is formed of at least seven planets that orbit around a star that according to trappist.one is 12 times less massive than the Sun (“About Trappist-1 p.1”). Following findings made by the TRAPPIST, Spitzer space telescope, the Very Large Telescope, UKIRT, the Liverpool Telescope, and the William Herschel Telescope revealed new planets in the system and more facts about the composition of the planets. The discoveries made about the planets in the Trappist-1 system show surprising and promising aspects that might be promising evidence for a habitable

An exoplanet can be defined as a planet that orbits a star outside the solar system. One of the many exoplanets that could possibly be habitable in the near future are far away. For example, Kepler-186 is around 500 light years aways to put that in perspective that is around 5,878,625,373,183.607731 Miles away. That is why we know so little about these planets that could support life on them.

The main searches for exoplanets are being done by space missions. The Kepler space mission is finding the most exoplanets, however there are many other space missions like Gaia, MOST, CoRoT, and SWEEPS, that are finding exoplanets in habitable zones. There are also ground missions including the Anglo Australian Planet Search and HARPS which is done in Geneva. This graph shows all the exoplanets found that are less than 10Me or 1.5Re mapped on the habitable zone. The sizes of the circles indicate the radius of the planet, which has been estimated, if not

of other planets such as Saturn or Mars are a great way of studying other planets surfaces

The first exoplanet found, Peg 51 b, challenged the then present theory of giant planet formation. Models of giant planet formation stated that Jupiter-like planets form at distances of 4-5 AU, AU being the distance from

Uncovering the mysteries of Jupiter is a crucial step for a greater understanding of our Solar System. Being the massive planet that it is, this mysterious planet may hold many answers to how our the Solar System formed and evolved. The understanding of the origins of the universe includes answers even to the formation of Earth itself. Many believe that the research of Jupiter will lead to discoveries on planet formation and the role of giant planets on the formation f stars and other smaller bodies. Mysteries of Jupiter include its composition, what is under its clouds, what is in its core and its magnetic field. Research on the amount of water in the planet will tell us about the
