Earth Size Exoplanets

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,

NASA’s discovery of exoplanets was released in February of 2017. It publicized the finding of several planets that were primarily similar to the size of Earth. These planets were established in the “habitable zone” of a singular star, which is called TRAPPIST-1. The system includes seven worlds that all have the possibility of containing water and various resources to acknowledge life. Future studies on the system will allow humans to examine the conditions on of the system and

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.

Many people found and/or saw the peculiar planets but had not realized what they had saw till months later years even! To this day both America and Europe claim to have found the “first”. To find these Exoplanets, scientists discovered a destroyed star known as a ‘pulsar’. This pulsar, is a core star that had died in a supernova explosion. It shoots radio waves out which helps scientists locate said planets. ‘Wolszczan’ found two ‘pulsars’ by 1992 and another, two years later. another exoplanet was discovered by Michel Mayor and Didier Queloz in 1995. This exoplanet came to be known as fifty-one peg. In 1989 The discovery of the first exoplanet was announced, though it is still unknown of whether it was discovered by someone from America or

Warbler is a world renowned scientist known famously for his many interesting and thought-provoking theories based on our universe and the many others there may be. Challenging the possibility of things almost too complex for us to fathom is a pass time for him; dabbling in the existence of time travel and alternate realities. Mr. Warbler has recently stumbled across something truly “out of this world”. He, along with his team at NASA, believe that they have found a planet that has many attributes and characteristics of our current planet.

No one could have imagined, back in the mid-sixties, that the exploration of the moons of Jupiter laid not in the next century but only fifteen years ahead. Nor had anyone dreamed of the wonders that would be found there - although we can be quite certain that the discoveries of the twin Voyagers will one day be surpassed by even more unexpected finds. When 2001 was written, Io, Europa, Ganymede, and Callisto were mere pinpoints of light in even the most

Scientific discoveries are made as time moves forward, Kepler 62f has not been the exception in the scientific community. Kepler 62f, is an Earth size planet in the habitable zone of a star smaller and cooler than the sun, located about 1,200 light years from planet Earth in the constellation known by the name of Lyra. Kepler 62f orbits its host star every 267 days and is roughly 40 percent larger than Earth in size, the size of Kepler 62f is known, but its mass and composition are not. However, based on previous scientific discoveries of similar size landmarks that are rocky, scientists are able to determine its mass by association of scale. Very much similar to our solar system, Kepler 62 is home to possible habitable zone worlds; Kepler

The Kepler Mission began in March 7th, 2009. The goal of The Kepler Mission is to “survey a portion of our region of the Milky Way galaxy to discover dozens of Earth-size planets in or near the habitable zone” (NASA). This is accomplished by using a photometer to look for transits, then transferring the data to earth through the Deep Space Network. Once a planet has been detected, a number of different methods can be used to determine the planet’s size, composition and habitability. In order to understand The Kepler Mission completely, one must understand the structure of Kepler, the search methods used, how the data is interpreted, and the implications of the results.

Scientists who study astronomy, astronomers, are trying to research the atmosphere of exoplanets to discover planets that have conditions able to be lived in. Since Earth used to not be habitable during the Archean Era because there was low levels of oxygen and lots of organic chemicals. During this time, it is possible that Earth had an atmosphere haze, seen in exoplanets today. This thick haze allows little light through allowing the planet to reach extremely low temperatures. As scientists have done more research, they have found that as this haze gets thicker and less light get through, there is also less chemicals driven by sunlight in the atmosphere. Some of these chemicals are necessary for creating this haze and without them, haze can’t

The buzz yesterday about a second Earth was answered when NASA announced the results its phoenix-like telescope Kepler , had found. The exoplanet that created so much excitement has a size and age comparable to Earth’s, and, critically, even exists in the goldilox zone of its Sun-like star, ensuring its neither freezing nor burning away any possibility of complex life.

We all have heard about the discovery of a new plant but no one really pays attention to the type of strategies and methods astronomers use to identify a new planet. Astronomers study the astronomical sense of space, what truly lies away from our peaceful planet earth. One famous Theoretical Physicist known as Stephen Hawking’s is our modern day Einstein. Hawking’s has been in involvement of the discovery of many planets and far away galaxies. There are many different types of methods, and tools are used to discover, and identify new planets and galaxies. Radial Velocity method, the astrometry method, Gravitational Microlensing method are used along with many other methods to discover Exoplanets in particular. (Cane 2013). Exoplanets are planets

An exoplanet is a planet that orbits a star other than outside our solar system. Over the course of years, scientists have found different exoplanets. An example of an exoplanet is Kepler- 452b. Kepler- 452b is said to be like a Earth 2.0 because its has similar conditions to Earth. . Scientists speculate that it has rocky terrain just like Earth and it possibly has a atmosphere, lots clouds and even maybe active volcanoes. Kepler- 452b is orbiting a slightly larger star than the sun so its temperature is originally thought to be slightly more than Earth’s. Now we know that it is too hot to support human life.

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

The Protoplanet hypothesis and the Planetesimal hypothesis are different from this. Planets form from compact masses made in whirlpools in the Protoplanet hypothesis, and planets are created from collisions of planetesimals in the Planetesimal hypothesis. The Protoplanet and Planetesimal hypothesis also have similarities such as the date they were proposed. In addition to both being proposed in the 20th century, these hypotheses both involve a passing star. While the star in the Protoplanet hypothesis explodes and causes the cloud to collapse, the star in the Planetesimal hypothesis pulls chunks off the Sun. The Planetesimal hypothesis is not the only hypothesis the Protoplanet hypothesis shares similarities with. The Nebular hypothesis and the Protoplanet hypothesis both involve the law of conservation of momentum. Furthermore, the Nebular hypothesis involves particles leaving the Sun just like the Planetesimal hypothesis. Although these hypotheses have multiple connections and contrasts this comparison shows that they share fewer similarities than
