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.

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.

Perseids Perform Positively Perfectly

Did you see any shooting stars in the past few nights? If you did it was because the earth once again passed through the dust-tail of the comet Swift-Tuttle in its annual orbit of the sun, creating a wonderful show of meteors burning up high above our heads in the beautiful summer sky.

Don’t feel bad if you think you missed it, because the earth is actually in the dust of the comet for several weeks, and shooting stars, or meteors, will be  visible during the entire time, until about August 24th. Although the peak time for viewing is on Wednesday night until Friday morning, August 11-13, you can still enjoy a breathtaking sight by finding a dark spot with the minimal amount of light pollution, lying back on a blanket, and staring up at the night sky. With luck you should be able to see about 60-80 meteors/hour.

Perseids Visible with No Moon in Sight

This year we are lucky that visibility for the annual Perseid meteor shower will be ‘stellar.’ That is because the shower, which always falls from the 11th to 13th of August, this year will not have a moon ruining the visibility, which can sometimes happen. Where will the moon be, perhaps you are asking. Well, the phases of the moon are well known by all; the fact that the moon starts out each month as a tiny crescent resembling the tip of a thumbnail and grows to be a bright, full circle two weeks later, and then shrinks again until the moon disappears altogether is noticed by all. But what many people do not pay attention to is that the moon rises and sets later and later each night. When the moon is small, at the beginning of the lunar month, the moon sets about the same time as the sun. About two weeks later the moon is full, and rises at about the same time as the sun sets, and sets at about the same time as the sun risesThe process takes places in a cycle which is almost impossible to break tadalafil online mastercard out of.

That is why, when the moon is full we see it  the entire night.  At the end of the month you would need to wake up just before sunrise to witness the moonrise, and the only time the moon is in the sky is during the day, when it’s view is washed out by the brightness of the sun.

This year the Perseids happen to fall during the first few days of the lunar month, and the moon will have set shortly after the sun, and will no longer be visible in our nighttime sky. Watch for it this Thursday evening, August 12th, setting in the west an hour or two after the sun has set. It will just be a tiny crescent, but it will be there.

Hunley Project Celebrates Ten Years of Research

For the past 10 years the “Hunley Project” has brought together mystery, history, science and technology, creating interest that is not just regional, or national, but international. What is this project of which I speak? It is the story of the world’s first successful combat submarine, which was raised from the bottom of the sea four miles from Charleston Harbour in South Carolina in the year 2000.

The H.L. Hunley was a top secret, private project built in Mobile, Alabama in 1863. It was designed by an engineer from New Orleans named James McClintock, who was hired privately by a group of investors who believed they could make a fortune getting through the blockade which the North had imposed on the South during the Civil War of the United States. On February 17, 1864 the Hunley detonated an explosive charge into the hull of the USS Housatonic, which created a hole in the ship  large enough for a train to pass through. The ship sank within minutes, killing five crewmen and leaving over 100 stranded in the sea. Shortly after that the Hunley disappeared. Its whereabouts were not known for 131 years, until a diving team discovered it four miles off the coast of Charleston in 1995.

At the time of its discovery the sub was buried under five feet of sand and 27 feet of water. It took five years to recover the sub, coming to the surface after 136 years underwater, on August 8, 2000.

Today, ten years later, the Hunley has so far earned about $120 million for the state of South Carolina as thousands of tourists from all over the world flock to gaze at it every year. As scientists and researchers continue to examine and learn from the Hunley and find ways to better preserve it, this amazing bit of history continues to reveal more about itself and the times from which it came.
