The Universe and Our Galaxies The Universe and Our Galaxies Examples of Elliptical (Messier 87 ) and Spiral Galaxies (NGC 3559) Examples of Elliptical (Messier 87 ) and Spiral Galaxies (NGC 3559) Edwin Hubble was one of the first people to actually realise what a galaxy is‚ the measurement of the “Hubble Tuning Fork” Classification scheme shows how round or rightly wound their “arms” are. E0 means that an elliptical galaxy is extremely round‚ whilst E7 is flat. However not all galaxies

specialists shaking their heads‚ a small asteroid completely unrelated to 2012 DA14 struck Earth only hours before the publicized event. The impactor flew unexpectedly‚ literally from the direction of the sun where no telescope could see it‚ and took everyone by surprise as the meteor speckled across the sky above Russia’s Ural Mountains. The large fireball was observed on the morning of Feb. 15‚ 2013‚ in the skies near Chelyabinsk‚ Russia. A relatively small asteroid caused the fireball that entered the

Moon. 4. How are comets different from asteroids? One of the main differences between comets and asteroids are what they are made of. Asteroids are made up of metals and rocky materials while comets are made up of ice‚ dust and rocky material. Asteroids formed near the sun while comets farther away. Comets have tails while asteroids don’t. Also another difference is their orbit patterns. 5. Of what are comets made? Ice‚ dust and rocky material. And asteroids? Metals and rocky materials 6. If you

many families of land (terrestrial) plants and animals‚ including most of the dinosaurs. Finding out how this extinction occurred included theories about a combination of natural disasters‚ the already decreasing population of the dinosaurs and an asteroid impact that either magnified the already reduced population of dinosaurs to extinction‚ or single-handedly did the damage. An evaluation of theories and hypotheses is essential in order to really understand what caused the dinosaurs’ demise‚ through

One day‚ a rose appears on his asteroid‚ and as he cares for it most deeply‚ thinking she is the most wonderful‚ special creature ever - he is depressed to assume that she does not love him back. The little prince then leaves his asteroid and rose. As he lands on many asteroids‚ each one is occupied by a different adult. First

troChapter 1: Charting the Heavens (Astronomy Today) SUMMARY The universe is the totality of all space‚ time‚ matter‚ and energy. Astronomy is the study of the universe. A widely used unit of distance in astronomy is the light year‚ the distance traveled by a beam of light in one year. Early observers grouped the thousands of stars visible to the naked eye into patterns called constellations. These patterns have no physical significance‚ although they are a very useful means of labeling regions

riddled with craters‚ formed by many asteroids smashing into its surface. These crater differed greatly in size‚ making it easy to assume that the larger the asteroid‚ the larger the crater. While this is partially true‚ it is not the only factor that controls crater size. This experiment will be exploring the asteroids speed and how this effects a craters size. Aim This scientific experiment was conducted to find how the impact speed/energy of an asteroid affects the diameter/size of a crater

Topic: Why Did Dinosaurs Go Extinct? A Gradual and Sudden End to Their Reign Introduction: About 65 mya almost three quarters of the animal and plant species on earth went extinct. This mass extinction is known as the Cretaceous-Paleogene (K-Pg) extinction event. The Cretaceous was the last period of the Mesozoic Era which is when dinosaurs lived from about 250 to 65 mya and the Paleogene is the first period of the Cenozoic Era that started about 65 mya which is the Era that we are currently living
