Historical Solar Eclipse 2017 Following Adventure

On August 21, 2017, all of North America will be treated to an eclipse of the sun. Viewers around the world will be provided a wealth of images captured before, during, and after the eclipse by 11 spacecraft, at least three NASA aircraft, more than 50 high-altitude balloons, and the astronauts aboard the International Space Station – each offering a unique vantage point for the celestial event.
Over the course of 100 minutes, 14 states across the United States will adventure experience more than two minutes of darkness in the middle of the day. Additionally, a partial eclipse will be view able across all of North America.
 The eclipse will provide a unique opportunity to study the sun, Earth, moon and their interaction because of the eclipse’s long path over land coast to coast. Scientists will be able to take ground-based and airborne observations over a period of an hour and a half to complement the wealth of data and images provided by space assets.
It is never safe to look directly at the sun's rays - even if the sun is partly obscured. When watching a partial eclipse you must wear eclipse glasses at all times if you want to face the sun, or use an alternate indirect method. This also applies during a total eclipse up until the time when the sun is completely and totally blocked. During the short time when the moon completely obscures the sun - known as the period of totality - it is safe to look directly at the star, but it's crucial that you know when to take off and put back on your glasses.
During the 21st century, there will be 224 solar eclipses of which 77 will be partial, 72 will be annular, 68 will be total and 7 will be hybrids between total and annular eclipses. Of these, two annular and one total eclipse will be non-central,
 In the sense that the very center (axis) of the moon's shadow will miss the earth (for more information see gamma).
 In the 21st century the greatest number of eclipses in one year is four, in 2011, 2029, 2047, 2065, 2076, and 2094. The predictions given here are by Fred Espenak of NASA's Goddard Space Flight Center.

So far, the longest duration in which the moon totally covered the sun, known as totality, was during the solar eclipse of July 22, 2009. This total solar eclipse had a maximum duration of 6 minutes and 39 seconds. The longest possible duration of a total solar eclipse is 7 minutes and 32 seconds. The longest annular solar eclipse of the 21st century took place on January 15, 2010, with a duration of 11 minutes and 8 seconds. The possible maximum duration is 12 minutes and 29 seconds. The eclipse of May 20, 2050, will be the second hybrid eclipse in the span of less than one year, the first one being on November 25, 2049.

A solar eclipse (Annular) occurred on February 26, 2017; the last solar eclipse (Total) occurred on August 21, 2017.


The list contains the date and time of the greatest eclipse (in dynamical time, which in this case is the time when the axis of the Moon's shadow cone passes closest to the center of Earth; this is in Universal Time). The number of the saris series that the eclipse belongs to is given, followed by the magnitude of the eclipse (the fraction of the Sun's diameter obscured by the Moon) and the type of the eclipse (either total, annular, partial or hybrid). For total and annular eclipses, the duration of the eclipse is given, as well as the location of the greatest eclipse (the point of maximum eclipse) and the path width of the total or annular eclipse. The geographical areas from which the eclipse can be seen are listed.

Dogs Sled Adventure Do You Play!

Sled dogs one kind of snow ride with Crazy dog they were important for transportation in arctic areas, hauling supplies in areas that were inaccessible by other methods. They were used with varying success in the explorations of both poles, as well as during the Alaskan gold rush . Sled dog teams delivered mail to rural communities in Alaska and northern Canada. Sled dogs today are still used by some rural communities, especially in areas of Alaska and Canada and throughout Greenland . They are used for recreational purposes, and are raced in events known as dog sled races such as the Iditarod. There at Crazy Dog Kennel we let “dogs be dogs”; they are socialized with the goal of letting them become an integral part of the dog community. There are no failures at our kennel; all of the dogs are successfully rehabilitated and go on to race with us or are sent on to adoptive homes where most are used for recreational mushing. Sled dogs also make great house pets and many of o...

Swimming with the turtles

Here are a lot of different opinions about swimming with the turtles. I really don't like the look of the water, it's quite brackish but then again the experience itself is amazing swimming with turtles . Of course your choice and kids love it must. If u do must in life one time you must get a amazing pleasure with your best swimming company turtles, feeding the turtles, new experience, best exercise, new adventure in life. Ifu visit to sea side (Va-i-moana) Savaii. in, it's on the way to (Manase) where most of the fale resorts are (the south coast), and you can go the long way round if you like but it would probably ad an hour or more to your trip. Could you please write and tell us what your experience was like if you do decide to swim with the turtles. I have always wanted to check this out when we eventually travel to (Samoa). I am a turtle lover here and would love to see them but I am a bit perturbed about the conditions that they are kept in? ...
