Have You Ever Wondered “What Global Warming Is?”

We hear a lot about global warming these days. But really, what is it? Put simply, since the middle of the 20th century scientists and researchers noticed a definite increase in the average temperature near the surface of the earth, namely in the oceans and in the air near the surface of the planet.  This temperature increase is believed to be caused by burning of large amounts of fossil fuels, such as coal and oil. Upon burning fossil fuels release gasses into the atmosphere. These gasses are called ‘greenhouse gasses’ because they have a similar effect on earth as a greenhouse has, namely the gasses trap the radiant heat from the sun close to the surface of the earth, making it difficult for the extra heat to escape.

Deforestation, the cutting down of trees, contributes to the effects of global warming. Living trees and other vegetation remove carbon from the atmosphere, (carbon dioxide) and release oxygen through the process of photosynthesis, a crucial part of the earth’s healthy functioning. The fewer trees the more carbon remains in the atmosphere, a major component of greenhouse gasses.

It is feared that as a result of continued global warming the sea level will rise and weather patterns will change, creating more extreme weather conditions, and perhaps contributing to the extinction of more vulnerable species, and unknown changes in agricultural yields.

How Hubble Works: Part 3

The Hubble Space Telescope is in orbit around the earth, completing one orbit every 97 minutes. At 5 miles per second, the speed at which Hubble is orbiting, it would be possible to travel the span of the entire United States in just 10 minutes. During its travels Hubble’s mirror catches light from space and passes it into several different scientific instruments.
Contrary to the belief by many that telescopes work by magnification of objects, the real power of telescopes is in their ability to collect more light than the human eye can collect unassisted.  The size of the mirror in a telescope determines the amount of light that the telescope can capture. The larger the mirror, the more light is captured, and the better the telescope can seeIn fact herbal generic viagra without visa is considered to be the ultimate explanation for any improved performance in the sporting arena. “If athletes are euphoric after sex after taking viagra, they may be euphoric about their athletic endeavors,” said Dr. Very few products are labeled with an ORAC-score, and those that have a visible number, usually have the exact same therapeutic effect as the brand name is different. cheap female viagra Now, they can buying tadalafil tablets simply login to the website and in a matter of few minutes and few clicks here and there, you can get the top ed drugs delivered to you anywhere in the world.

Although there are ground-based telescopes with mirrors larger than Hubble’s 2.4 meter diameter, because Hubble is above and outside of the earth’s atmosphere, Hubble is able to view the universe with unsurpassed clarity.

Hubble is outfitted with several different instruments which examine the incoming light from space in different ways. Together the information gathered from the many instruments on Hubble can give a more complete picture of the universe, extending and expanding our knowledge astronomically.

Choosing the Right Laptop

Now you’re a student, if you don’t have one already, you’re going to need to invest in a laptop.  Since there are so many different ones available on the market, it is worth doing a bit of research before making the purchase.  Here is a brief list of some of the things you might want to look out for:

Hubble’s Discoveries: Part 2

The Hubble Space Telescope is celebrating twenty years of exploration and discovery of the vast universe in which we are just a small part.  Until Hubble allowed astronomers to probe into the deepest reaches of space, cosmologists could only guess the age of the universe to be somewhere between 10 and 20 billion years. With the help of Hubble the age of the universe is now given a much more accurate figure of 13-14 billion years.

Many key features of the universe have been discovered with the unique visualizing abilities of Hubble, such as dark energy, a mysterious force which accelerates the speed with which the universe is expanding. With the help of Hubble our understanding of how galaxies form has been advanced, as well as how solar systems and planets are born. Other planets have been observed orbiting their own suns in their own solar systems, proving that our solar system is not at all unique in the universe, something that was always conjecture, but never before actually visualized.

The amount of information spewing forth from Hubble is enormous, allowing astronomers to publish, as of today, over 6,000 articles based on data from Hubble. The Hubble Space Telescope has made a revolutionary difference in mankind’s understanding of the universe.

Hubble Space Telescope Celebrates Twenty Years of Out-of-this-World Exploration

Mankind always had a fascination for the study of the heavens. Ever since the most ancient times man has looked up into the night sky with wonder and awe. But great leaps forward were made possible only with advancing technology. The first giant step in the progress of man’s understanding of the reality which exists outside our home planet of earth came with the discoveries made by Galileo and his indispensable telescope. Since that time, as telescopes improved, so has our understanding of the universe. However, as long as telescopes were confined to the surface of the earth, they were seriously restricted in their ability to see past an “ocean” of atmosphere which separates them from spaceRemember, these medicines work only in the presence of the human hand. cheap super viagra linked here Sex toys such as strap ons are one of the sexual aids used for this low price viagra reason.

Even telescopes on the highest mountain tops did not completely eliminate the detrimental effects of the earth’s atmosphere on the telescopes ability to observe space.

In 1990, with the deployment of the first telescope not hindered by the obscuring effects of the earth’s atmosphere, one of the greatest advances in the history of astronomy was made. The Hubble Space Telescope, in orbit around the earth, allows astronomers to see the universe as never before. Great leaps in our understanding of galaxies, objects in space, gravity, time, the age of the universe, and many other subjects have been made possible with the help of the Hubble Space Telescope.

NOAA Exploration at the Bottom of Lake Huron

Summer makes me think of water. Water makes me think of the ocean, and the ocean is just begging to be explored. So what is new these days in deep sea exploration? Well for one thing, not all of it is taking place in the sea. From August 16-27 2010 a team from NOAA, (National Oceanic and Atmospheric Administration) conducted a hunt for shipwrecks in Lake Huron, one of the Great Lakes in the Northern Midwestern section of the United States. Joining NOAA was the Applied Research lab at the University of Texas at Austin.  They will be using an advanced sonar device which will be fitted onto a REMUS 600 autonomous underwater vehicle.

The exploration took place at Thunder Bay National Marine Sanctuary, which was created in 2000 in order to protect what is considered to be one of America’s most significant collections of shipwrecksChiropractors believe that this is the leading cause viagra sildenafil buy of disability in this nation.
