Sun's distance to Galactic center is 26,000 light years. Sun's Galactic rotation period is 220 million years. Escape velocity at Sun's position is 550 km/s.This step, stars will be investigated. The globular clusters in the Milky Way have proven through this century to be irreplaceable objects in an amazingly wide range of astrophysical studies.(Harris, 1996). The Milky Way contains between 200 billion and 400 billion stars.
There are approximately 100 billion different solar systems in the Milky Way. Our dolor system is 25,000 light years away from the center of our galaxy. Our galaxy is so big we have only gone 19.5 kilometers from home. The farthest humans have gone is to the moon and back, which is only 238,900 miles away. 2.
Humans will eventually have to venture out into space, and we need to do it now instead of waiting until it is too late. Plus, some of the discoveries made in space can help save our planet, like a discovery of a plentiful source of ununpentium. There is also the fear of finding extra terrestrial life, and bringing it back to earth. Not necessarily alien like creatures that will invade earth, but like bacteria or viruses that can be detrimental to human life. Although this is possible, it is extremely unlike.
Kepler-425b is the first near-Earth-size world to be found in the habitable zone of star that is similar to our sun. The habitable zone is a region around a star where temperatures are right for water- an essential ingredient for life, as we know it- to pool on the surface. However, scientists do not know if Kepler-452b can support life or not.
The Romans only knew of several objects in the sky at this time, the Sun, the Moon, and the five brightest planets. Mercury was named after the Roman messenger god, as it traveled the fastest in the sky. As said from a page created by Wikipedia on the planet Mercury. Mercury is positioned as the closest planet in our solar system to our
Many humans in certain countries are constantly in danger because of the many wars in the world and terrorist attacks. There would be no wars on Mars, or terrorism because military weapons and terrorists would probably not be sent to Mars. Humans would be safer because of
On the night of Wednesday, November 11, I went to the RLM. At 7:25 I observed Uranus at approximately 40 degrees in the east southeastern sky. It only appeared as a small whitish dot against a vast black background. I found it by looking directly into the lens where the astronomers had pointed the telescope in the sky. Discovered in 1781, Uranus is the third largest planet in the solar system.
At the first state building up the atmosphere, it took 90 years and cost 500 billion USD and continues to the last state Mars colonization, it will use 480 years and cost almost 4 trillion USD dollar. Closing: Signal:
As I have seen on the news I know that rovers are being sent to mars to study and examine the climate. I also know that the earth is going through massive climate changes that could devastate the human race in the far future. Because it is far in the future you may think that we have all the time in the world and yes that is true but complications will come up and maybe set us back. If we spend just a small amount of our total budget we may have a backup plan that will always be there to save us. I know it may not be clear now but space research is very important and I truly believe that we need
In other words ellipses can be round or elongated; the degree of stretch is known as eccentricity. Eccentricity is defined as the ratioc/2a. C defined as the distance between the two focuses of the ellipse and a is the semi-major axis. In fact, a circle is an ellipse with an eccentricity of zero. Kepler`s second law is the speed of the planets along their elliptical orbits is such that they sweep out equal areas in equal periods of time.
Mars. It’s a pretty unforgiving place. On this dry, dessicated world, the average surface temperature is -55 °C. And at the poles, temperatures can reach as low as -153 °C. Much of that has to do with its thin atmosphere, which is too thin to retain heat.
On the northern slope of Hawaii's Mauna Loa Volcano, six scientists have been living as though they are inhabiting Mars. The reason; to see if the diet they are on will be enough for a real astronaut to survive on. For four months, Hawaii Space Exploration Analogue and Simulations (HI-SEAS) participants have been studying how their food supply has effected their energy, weight and of course, their appetites. The mock-astronaut's new diet has resulted in minor weight loss for every member. This, of course, could be from the frequent exercise that the scientists did not partake in while at home.
Henrietta Leavitt is considered one of the most important contributors to the field of astronomy. She discovered that variable stars with greater luminosity had longer periods. Leavitt was left in charge to identify variable stars in the Small Magellanic Cloud. She realized that the stars she had observed were indeed variable stars – named Cepheid Variables – because their brightness changed in a pattern. Like variable stars, the Cepheid Variables dimmed and brightened in regular periods.
The book, No Summit out of Sight, written by Jordan Romero and Linda Le Blanc, describes the experiences Jordan Romero had while on his journey to climb the Seven Summits. Realizing his dream at age nine, Jordan decided to climb the highest peak on each continent, and with the support of his family, set a world record as the youngest person (age fifteen) to climb the Seven Summits, even climbing both Mount Kosciuszko and the Carstensz Pyramid, which are topics of debate as to which mountain should be the official summit for Australia. Having read this book and being inspired by Jordan’s dream, I decided to climb Mount Kosciuszko, the shortest summit at 7,310 feet. Stepping out of my comfort zone and pushing away my fear of heights, I got to experience a taste of mountaineering and connect with nature. Mount Kosciuszko was the second mountain Jordan climbed and the mountain I decided to climb.
