.... galaxies like NGC 4261. Currently they believe that the disk of dust is the remnant of a smaller galaxy that fell into the core of NGC 4261. The black hole will swallow up the gas from the smaller galaxy over the next 100 million years. Researchers believe that while the gas is being swallowed by the black hole, the process will produce some amazing fireworks. The second puzzling question that astronomers are trying to answer is why isn't the black hole at the center of the galaxy? According to images from the Hubble Space Telescope, the black hole is 20 light-years from the center of the galaxy, but since the black hole is so massive it is hard to explain how it co ....

.... or for the actual ingredients for these weapons.

.... temperatures) which is vital in preventing harmful ultraviolet rays of the sun from reaching the earth's surface. Aerosols in the atmosphere have a detrimental effect on the ozone layer. Large holes in the ozone layer are forming over the polar regions and these are increasing in size annually. Paradoxically, ozone is toxic! Undiluted ozone is bluish in colour. Liquid ozone is bluish-black, and solid ozone is violet-black. Oxygen is very reactive and capable of combining with most elements. It is essential for respiration of all plants and animals and for practically all combustion. history of oxygen Leonardo da Vinci suggested that air consists of at leas ....

.... Environment and People Mercury is one of the biggest environmental problems that exist because it is hard to get of once in the environment. In the past, mercury was used to make things like paper, put in paint and thermometers, and as an agricultural pesticide. The Minamata Disease is a good example of what could happen if mercury enters into the environment. In the mid 1950's, more than 100 Japanese were poisoned by fish that contained methyl mercury. The mercury came from industrial waste that had been dumped into the bay where the fish were caught. The mercury bioaccumulated up the food chain. The cats the were eating the fish showed the symptoms first. They began ....

Moreover the deadlines for plants to meet EU-directives are getting close, and everything se-ems to show that the laws will be enforced. Yet far from all companies have to meet with the raised finger of the law to start investing in their environmental responsibilities. Investments on a volunta-ry basis are often due to the fact that it makes good ecnomic sense or because it gives the corporate image a face- lifting. ....

The females are usually responsible for the nursing portion in the unit. Gorillas are peaceful and tolerant by nature. Whenever two groups meet, they either ignore each other, or they give each other a grumpy grunt. Sometimes the two groups would even stay together, and then eventually separate.
