The basic idea of star formation is gravitational collapse – the contraction of a region of gas under the influence of gravity. This is a simple process that would be expected to occur in any region of material dense enough for collisions between atoms to radiate away energy. However‚ the gas must be dense enough for collisions to occur and the temperature must be low enough for the atomic velocities not to be able to escape the system’s gravity‚ so star formation only occurs in a few areas.

of Uranus concluded that Galileo and Flamsteed had observed similar objects a century ago. Later in his career‚ Fredrick discovered two of Uranus’s moons‚ as well as two moons around the planet Saturn. In addition‚ he was also the first to suggest that nebulae consist of stars. With the new discovery of the planet Uranus‚ the solar system had just grown bigger introducing many new possibilities of space observation. Even though at the beginning‚ Fredrick did not have the tools to explore the universe

that I left planet earth and embarked on one of the most important missions in NASA’s history. I should probably back up though‚ and explain to you how this came about. April 16th was sunny with only a few clouds in the sky‚ the smell of spring was in the air and with the end of second semester right around the corner‚ the quad was packed with people eager to catch some much desired sun rays. Unfortunately for me though I was stuck in astronomy. That day’s topic was our very own planet earth. Dr

Earth masses[11]). Another possibility is that Kepler-22b is an "ocean-like" world. It might also be comparable to the water-rich planet GJ 1214 b although Kepler-22b‚ unlike GJ 1214b‚ is in the habitable zone. If it has an Earth-like composition‚ the compression of material in the interior of the planet would give an overall mass greater than 4 Earth masses [12]. Such a planet would also produce surface gravity greater than 7 times that on Earth. This is ruled out to at least 1-sigma uncertainty by radial

Last August 24 the Voyager Adventures visited our school to show to us the outer space. They have made some activities that will enlighten the query minds and thoughts of the students about the outer space. To widen the knowledge we have already gained.

There is just so much we can do in 50 years and predictions must be made. In 50 years we will have the ability to go outer space without need of all the training that astronauts nowadays require‚ and our cars will be nothing like how they are today because within 50 years the world as we know it will be completely

solar systems have been concluded that the universe has many different types of solar systems and noted that Our Solar system was formed 4.5 billion years ago. Our solar system consists of the Sun‚ 8 planets‚ and 5 dwarf planets and asteroids. Many planets have their own moons. However‚ not all planets have moons. Based upon what we learned in the astronomy course of how everything has a beginning and an ending. Our solar system got created from the cloud that was the Solar Nebula. All stars exist

3.3. Moons of Uranus 3.3.1 Introduction Uranus‚ the seventh planet of the Solar System‚ has 27 known moons. Uranus’s moons are divided into three groups: thirteen inner moons‚ five major moons‚ and nine irregular moons. The inner moons are small dark bodies that share common properties and origins with the Uranus’s rings‚ the five major moons (Miranda‚ Ariel‚ Umbriel‚ Titania‚ and Oberon) are massive enough to have achieved hydrostatic equilibrium. They range in diameter from 472 km for Miranda
