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

MINOR MEMBERS OF THE SOLAR SYSTEM ASTEROIDS Asteroids are small rocky bodies that have been likened to “flying mountains.” The largest‚ Ceres‚ is about 1000 kilometers in diameter‚ but most are only about 1 kilometer across. The smallest asteroids are assumed to be no larger than grains of sand. Most asteroids lie between the orbits of Mars and Jupiter. They have orbital periods of three to six years. Some asteroids have very eccentric orbits and travel very close to the sun‚ and a few larger

On February 20 2012‚ me and my daughter went to the Gates Planetarium in Denver to see the showing of the Wildest Weather in the Solar System. The first thing we did was to walk around the Space Odyssey and explore some of the exhibit they had. Then we went to see the show which I must say was far more thrilling then I or my daughter could have imagined. When you first walk into the Space Odyssey you are amazed it almost looks as thought your walking on to a spaceship or what I would imagine it

Earth is the only planet in our solar system that sustains life‚ and therefore one of the most intriguing planets because of its capabilities. Each of the seven other planets that orbit the same sun as Earth is interesting in its own way. Some planets share similar characteristics to those found on Earth‚ while other planets are completely different. An analysis of these terrestrial bodies‚ using comparative planetology‚ will allow us examine these qualities. However‚ before beginning such a process

"An Earth-like planet spotted outside our solar system is the first found that could support liquid water and harbor life." This comes from a NASA researcher. New life on other planets could mean so much for the future of humans. The only way to keep finding out new information about our solar system and beyond is to spend money to research it. The only

The Solar System The solar system still to this day one of the most fascinating subjects of study in the science world. In our time‚ we are one of the first generations to see the planets of our solar system up close‚ and we have been able to view evolution of these planets through time. Our solar system consists of a middle aged star called the Sun‚ 9 planets‚ about 100 moons‚ thousands of asteroids‚ millions of icy bodies‚ and many comets revolving around all of it. We can begin by looking

Approximately 557 Earth years is equal to 1 Eris year. Eris has a diameter between 2‚400 and 3‚000 km. Eris plays a big part in our Solar System and is important to us because it is the largest object and the largest dwarf planet to be found orbiting the sun since 1846‚ when Neptune and its moon Triton was discovered. In conclusion‚ Eris is the 10th planet in our solar system and is rocky unlike many planets before it. References: • Dwarf Planets; UB313 or Eris http://sse.jpl.nasa.gov/planets/profile
