Solar System Asteroids Space
342 wordsAsteroids are some of the many small or minor planets in the solar system that move in oval shaped orbits mostly between Mars and Jupiter. The largest of all asteroids is Ceres, with a diameter of 1030 km. Pallas and Vesta are next with diameters of 550 km each. In all, there are about 200 asteroids with diameters of more than 97 km with thousands of other smaller ones. Though plentiful, the Moon's mass still belittles the total mass of all asteroids in the solar system. The larger bodies tend t...

Billion Years Ago Solar System
2,233 words... alvarez's case, and see if it was flawed. This job was turning out to be more fun than I had expected. On my second reading of Alvarez's letter, I found it particularly dubious that the Cretaceous and Eocene extinctions should be excluded. How do we know that asteroids do not hit the Earth periodically? I asked. Maybe our failure to arrive at a theory just meant that we hadn't been clever enough. Not finding something is not the same as proving it is not there. I decided to reserve judgment....

Hubble Space Telescope Universe Continues To Expand Energy
786 wordsThe universe begins with a cataclysm that generates space and time, as well as all the matter and energy the universe will ever hold. For an incomprehensibly small fraction of a second, the universe is an infinitely dense, hot fireball. The prevailing theory describes a peculiar form of energy that can suddenly push out the fabric of space. On a rare occasion, a runaway process called "Inflation" can cause a vast expansion of space filled with this energy. The inflationary expansion is stopped o...

Meteor Impact Earth Objects Meteors
589 wordsMeteors are very common throughout outer space. They are being whipped around our solar system in every orbit possible. Normally they are peacefully and serenely floating through space, but one just has to look at the cratered face of our moon or Jupiter's moon Callisto to see that more than a few meteors journeys through space have been interrupted. The earth has been hit before and will be hit in the future, statistics show this. We must detect the meteors a long time before they cross paths w...

Gas And Dust Carbon Dioxide
1,584 wordsAsteroids sling through space, celestial debris of diverse origins, leftovers from the formation of the solar system, broken offshoots of parental asteroids or comets that have lost their glow. But if an asteroid were to smash into Earth, the result would mean a global catastrophe and life on our Planet could come to an end. The explosion would approach that of a million megatons of TNT- sixteen hundred times greater than the most powerful nuclear weapon ever tested (Barnes-Svarney 234). Asteroi...

Kilometers In Diameter Mitral Valve

The defect may require surgery to prevent sudden death, stroke, heart failure, and abnormal heart rhythms that cause fa...
