Comet – The Largest Comet In The Universe To Come Near Earth In 2031


As we all know the biggest and brightest comet in the entire solar system is going to be a result of a collision between two very big comets.

The object will whiz by at a great speed and could be visible as a shooting star or an asteroid. Comet ISON was originally going to be a large icy rock that came very close to our planet, however due to a massive collision it turned into a much smaller coma and comets are now known to be made mostly out of water. A recent study suggests that Comet ISON could have the largest comet in the history of the solar system; which if true, will revolutionize our understanding of how these spectacular bodies form and how they evolve.

When the biggest comet to be seen in over a century will come very near and burn up in our solar system is an event that astrology experts, space scientists, and science fiction authors have all are looking forward to. This huge space rock, known as comet ISON, is expected to break into several pieces as it whizzes by our planet. Many of you may remember this huge space rock from the 1980’s when it was first discovered. In fact, it was one of the first celestial objects to be visited by humans. Many predicted that it would become a big problem for the Earth.

You may be thinking that it is not possible for Comet ISON to make such a close shave with our planet. It will be very close, many hundreds of kilometers across, and it will be at least as wide as Halley’s Comet, which was only found to be about four hundred kilometers in width. This means that ISON could be even bigger than Halley. The largest comet ever observed will come very near and pass very close to our planet in 2031.

Tracking Wildlife Migration Due to Climate Change


Wildlife populations are closely monitored by satellites due to the fact that they are a source of information about environmental changes.

Satellites have been tracking the movements of animals for over 60 years and have learned how animals adapt to change, how fast or slow they can move and how long they can stay in one place. Tracking wildlife migration due to climate change shows us that certain animals can not keep up with the change in their environment and must move to find a different habitat to thrive in. Some species may already be in trouble in some areas while other animals may not show any signs of suffering at all. We just do not know which ones are which populations will suffer most during this recent warming trend.

Although warming trends cause many problems in nature, it is animals such as birds, insects, amphibians, and mammals which are directly affected by these changes. These types of wildlife reproduce differently and move around on land and in water more than other types of animals. The result is that they are very sensitive to changes in their environment and are at greater risk from climate change than most living things.

For example, at higher elevations in some habitats they have a very difficult time dealing with temperature change and rapid changes in humidity and temperatures. They must also be able to cope with sudden changes in their food supply due to expanding numbers of predators. If prey numbers increase rapidly then the rodents that live in the same food supply will also increase in number and this will aggravate the problem for the animals. They will have to eat more in order to keep up with the increased activity from both predators and prey. If they are unable to cope with the change in their environment they can become stressed and possibly perish.

What Are Dying Gas Wells?


What are dying gas wells? These are wells that have been producing natural gas for decades but are now in their decline.

These are the same gas that has been burned for heating homes for centuries, but has become scarcer as the world uses more of the same to warm homes and business. So, while this is an excellent source of fuel, it is also a finite source and the planet cannot use so much of it. This means that there are limits to how much can be produced and this has caused problems.

In this world there are always things that are in a state of change, this is because it is a fossil fuel has been said to be nonrenewable.

The earth is slowly being overtaken by gas and oil as a result of this change. So, its been said that its probably best to reduce reliance on fossil fuels if we are to avoid serious repercussions. This means using more non-petrol based energies such as geothermal and solar power. It also means looking to alternative sources of energy which are friendly to the environment and can be replenished rapidly.

Is Volcano Ash A Risk to the Atmosphere?


Many studies in recent years have concluded that there is a link between airborne volcanic ash and poor air quality.

Volcanic ash and other volcanic ash particles are constantly deposited on the ground and in the air. These ash particles act as a filter for many contaminants. Some research even suggests that airborne volcanic ash can reduce the effectiveness of air conditioners.

Are these claims true or do scientists need to conduct more research in this area?

A new study by the Environmental Protection Agency attempts to answer this question. This latest study looked at two sites near two volcanoes in the Eastern United States; one in Loudoun and the other in Lithia Mountain. The study measured the air quality in these two sites during two different times of the summer. They found that the air quality on the volcano site was significantly better than the air quality on the Lithia Mountain site. What does this mean?
