OS fiery sun ..
Scientists often attribute the cause of global warming of the Earth to human causes , but according to information obtained from the data issued by the six satellites to study the sun and the climate show
The opposite. Explained where that information to Earth swim in the overwhelming torrent of intense solar radiation , which increased during the twenty-four years, an increase of 0.05 per decade .
Had that change in activity has occurred since the beginning of the last century , it may be the main reason is the increase in the temperature of the climate , which was believed to be due to greenhouse gases only , and that the greatest height of human beings in it. Scientists say : The relationship between the change in the sun's activity and the climate on the ground is still not completely clear . But there is evidence that both humans and the role of solar activity in the climate change. He says a team of scientists from the Center for Climate Research at Columbia University , California : It's over 100 years we believe that the sun is going to be in control of the situation .
Is there water on Mars ?
Is still an ongoing debate about whether there is water on Mars or not? . It has explained the researchers at NASA and the University of Colorado that Mars planet cool, dry and inappropriate
Of life. Where water flowed in small quantities in the distant past when the asteroid collision billions of years ago , causing rain downpour continuing for decades . The scientists calculated that the collision offense
Cyan 250 km diameter of the planet extends a capacity of 100 million megatons of TNT (TNT).
This will lead to melt the ice in the poles , and it will enter the amount of water to the atmosphere and sufficient to bring down the rain deposition of up to 16 meters , and it seems that there was no time
To the evolution of life under the conditions that the flood as described in a report in December 2002 published in the journal Science . It also coincided Another explanation is more optimistic issued by the University of Arizona for the entry into force of the water on Mars , which says that the black lines on the surface of the planet is the cause of some of the activities Alheidromaúah modern . It has been said that there is salt water at low temperatures and low pressures on Mars , which led to the flow of water through these slopes , leaving those lines on its surface .
It should be noted that the planet Mars will be as close as possible from the ground, and the development of so-called ( reception mode ) where the ground will be between the planet and the sun. It will be
What could be a clearer vision of the monitors thousands of years ago , and that event will be
At the end of the month of August 2003 , and the department will monitor this astronomical phenomenon since the beginning of August.
Neutron stars
There are two types of neutron stars :
1 is believed that most of the stars as the stars begin Alnatrulah giant with enormous mass ( the mass of the sun as much as 8 times 20 ) but some ordinary star .
2 die giant stars in the form of supernova explosions
The second type , where the core of the star explodes into a ball of severe intensity atomic particles .
