join as the Tucson Amateur Astronomy Association and Saguaro Astronomy Club of Phoenix provide their knowledge and free telescope viewings each day. Visitors will be able to view Saturn along with star clusters and galaxies during the night, and the sun and planet Mercury by day. Everyone is encouraged to dress warmly because temperatures drop in the evenings. All visitors are also being advised to bring flashlights to navigate the telescope areas. This is the first time I've been able to reflect

Assignment 1 1. What are greenhouse gases and why do they affect the climate? At what wavelength band(s) of the electromagnetic spectrum do they absorb radiation? In your answer, give three examples of greenhouse gases and their wavelengths of absorption. Greenhouse gases are gases in the atmosphere that allow light through but block infrared radiation that is reflected off of Earth’s surface, not allowing the heat to escape and thus causing long term heating effects on our climate. The greenhouse

by Bausch & Lomb. Ray-Ban sunglasses............The World's Finest Sunglasses. In the late 1920's, the U.S. Army Air Corps approached Bausch & Lomb with an urgent request for an optical glass that would help fliers overcome the brutal glare of the sun. Responding to this need, Bausch & Lomb created the first Ray-Ban glass, which not only met, but far exceeded the exacting Air Corps standards. Today, Ray-Ban sunglasses are still manufactured to standards that produce the same level of excellence

GLOBAL WARMING The Ozone Layer absorbs ultraviolet radiation from the sun protecting all living organisms below from the dangerous radiation. The Ozone Hole is an area of weakness or depletion in the protective cover of the Ozone Layer over the North and South Pole. Scientist discovered in the 1980’s that the ozone layer was thinning at an alarming rate. This phenomenon was caused by chemicals that came from spray cans and refrigerants or in other words, CFC’s (chemical compounds with chlorine

(Reuters) - An Anglo-German team of astronomers has discovered a new planet orbiting a nearby sun at just the right distance for an Earth-like climate that could support life. The team actually found three new planets orbiting the star 44 light years away, but only one of them is in the so-called Goldilocks Zone, the band around a sun where temperatures are neither too hot nor too cold for liquid water to exist. "The star HD 40307 is a perfectly quiet old dwarf star, so there is no reason why

Introduction Humanity has searched for life in our solar system and outside of it for years. Speculation supporting and against the probability of life on other planets has been a subject of debate in the scientific word and beyond. The probability of life mathematically is extremely low even when all the elements of life are present. Stages of evolution and development needed to create life take time. This time that it takes to develop is difficult to come by in the Universe according to some

Aleeza Dauphin Global warming Recent increase in carbon, methane, and other toxic gases has resulted in changes to our climate or global warming. We can help reduce harmful emissions such as these by making lots of little changes in our everyday lives. For example, walking or biking to close destinations instead of driving, you’ll save gas and it’s great exercise. If walking or biking isn’t an option for you try to drive eco-friendly cars. Cut back on energy consumption by lowering your heater

available energy resources that can be exploited to satisfy the increasing energy demands in the world. Solar energy has been regarded as one of the most paramount and cardinal sources of renewable energy. As per scientists, the energy received from the sun in one hour is more than the whole world’s total produced energy in a year. It would take only around 0.3% of the world's land area to supply all of our electricity needs via solar power. Pakistan is going through a very severe energy crisis right now

To the boy who breathes ashes and dust, whose eyes contain the most beautiful sunset. Whose smile beams like the moon kissing the skies at cold nights. Whose autumn hair dances waltz in the spring wind. Whose fingers are pointed and long, hand soft as a cotton that I wish to hold forever. The stars and you are the same. You are beautiful but only at a distance. And kissed me like sending a thousand lightning on my spine. I tasted salt in your mouth as if you drank the waters of the ocean; good
