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

Phobos orbits Mars has an average distance of about 9380 km from the center of the planet and a rotational period of about 7hr 39 min. a = 9380 km = 9.38 x 106 m P = 7 hr 39 min = 7.65 hr = 27540 sec (27540sec)^2=4(3.14159)^2/(6.673x10^-11m^3kg^-1s^-2)(M1+M2)*(9.38x10^6m)^3 Which equals (9.38x10^6m)^3/(27540sec)^2* 4(3.14159)^2/(6.673x10^-11m^3kg^-1s^-2)=(M1+M2) equals to (M1+M2)=6.44x10^23kg Estimate the mass of Mars. Since the mass of Mars is so much greater than the mass of Phobos, (M1 + M2)

Active Galactic Nuclei (AGNs) are very luminous and dense regions in the center of galaxies believed to host Super Massive Black Holes (SMBHs). The electromagnetic radiation sent out from AGNs is conjectured to come from matter that the SMBHs accrete which then takes the form of an accretion disk circling the black hole. These accretion disks are best approximated with an irregular density and temperature distribution made up by very hot gas and plasma~\citep{skadowski2015global}. The common conceptual

A supernova is a marvelous thing that happens in space, and scientists are trying to use these explosions of stars to learn more about our expanding galaxy with the debris and elements that explode from the supernova, the largest explosion in space which can outshine many galaxies. Since the stars is a large distance away, when the supernova does happen, it would have actually happened a couple hundred years ago, because the light takes many years to reach our eyes. A supernova can happen in two

The general accepted divisions of our earths are the eon, era, period, epoch, and age, the two highest levels are the Phanerozoic and Precambrian. The Phanerozoic are made of three types of era, they are, Cenozoic, Mesozoic, and Paleozoic. The Precambrian is only made up of three era, they are, Hadean, Archean, and Proterozoic. The first one that came first to start the earth was the Precambrian. The Hadean Eon was names from the mythological Hades. This part of the Geologic time was when there

although it was quite crazy. The first step of their plan was to destroy the Star Tree. This tree was the tree Mr. Lion’s garden was known for. The Star Tree is two hundred feet tall with a star etched into the front of the trunk. Antelope Kieran and Antelope Henry, with some help from Nedned the Hippo, managed to tear down the Star Tree. They knew that if they destroyed the tree it would certainly distract Mr.

from space that could result in the extinction of human life on Earth is a supernova. A supernova is an explosion of a star in the universe. There are more than a hundred billion stars in our milky way galaxy (226). Most of the star explosions happen fairly far away from our solar system. However, because our sun orbits the galaxy we will be neighbouring different sets of stars at different points in time. Sometimes we are even just tens of light years away from a supernova (226). The closer you

All stars are born in nebulae. Nebulae are huge cold clouds of gas and dust. The formation of protostars requires huge clouds of gas and dust collapsing under gravitational forces. The stage of a protostar last an approximate of 50 million years. As stars grow, they also expand. When the core runs out of hydrogen and helium, the contacts and outer layers of the core expand, become cold, and the brightness decreases. This is also known as a Red Giant or a Red Supergiant which mainly consists of the

Rigel and Deimos. Rigel, the God of stars, and Deimos, the God of the planets, battled for the right to claim the sun as their own. The sun was not just another empty void waiting to be filled with life, it was the most beautiful thing ever to exist. The radiant sun was in fact a woman an oddity. Her name was Melea. Rigel wanted the sun as a star and Deimos wanted it as a planet. Deimos wanted to cripple Rigels power so he created a black hole to absorb his stars and temporarily weaken his brother

du Pont Telescope at Las Campanas Observatory in Chile (APOGEE-2S). Alongside the NASA planet-finding missions Kepler and Kepler-2 (Julia Fang et al, 2012) APOGEE-2 will measure the abundance of carbon, oxygen, nitrogen and iron in planet-hosting stars, and subsequently, determine what role these elements play in the formation of
