Black holes are among the strangest objects in the Universe. Hard to find, hard to explain, hard to understand and hard to imagine they defy the known laws of physics at their centre and provide mind boggling results at their edges. A black hole is impossible to see but there has been enough evidence to certify their existence. They are an important part of the solar life cycle and perhaps an even more important factor in galaxy formation. In 1785 a man named Peirre Simon Laplace conclude... more...

If you ask anyone if they know what Apophis 99942 is then the answer will likely be a blank one. Ask the same question again in 2029 and then in 2036 then people will most definitely be more aware. Apophis 99942 is a near-Earth asteroid and for a brief while was considered the most likely object to collide with Earth. In 2029 it will make a record-breaking near miss of our planet and in 2036 it will return with a 1 in 45,000 chance of hitting Earth. Apophis is estimated to be 415m long an... more...

When winters arrive, everyone from the mightiest to the smallest creature goes into hiding, especially in the cold regions of the world. Even humans for that matter prefer to stay within the confines of their warm home and put on warm clothes to maintain their body temperature. Animals, on the other hand, undergo hibernation. The most well known example of hibernation is bears. Before hibernation, they collect their food and store it to be used during the winter. Then they lie down in suc... more...

Wind energy is clean and renewable and provides a green complement to the world's reserves of coal, as well as oil and natural gas. Much of the world's wind has yet to be tapped and represents a great investment opportunity. Wind energy is a source of clean, non-polluting electricity. A single, well placed 750 kW wind turbine can prevent the emission of 5000 tons of CO2 into the atmosphere each year. It is a clean, cost-effective option from an abundant, domestic resource. Like all ele... more...

A pharmaceutical company is now currently working on a new drug that may be able to be used as a cognitive enhancer. In theory it could improve a person's working memory. Working memory is the process by which the brain can temporarily store and also manipulate certain information, such as remembering a phone number. This specific drug is able to enhance the functioning a dopamine type 1 receptor in the brain. Dopamine is an important neurotransmitter in the brain that has a variety of ... more...

You may have heard of hydrogen powered cars before, but generally when they are referred to people think of "fuel cell" vehicles prototyped by different car manufacturers. There is another type of hydrogen powered vehicle, one that uses hydrogen not as a primary fuel, but supplementally. In fact, anyone can convert their existing car to run on the hydrogen/gas/oxygen mix, at a low cost. Now when I say hydrogen, I am referring to HHO or Brown's gas specifically. This is a clea... more...

For centuries it has been wondered by man whether or not there was life on the Martian planet or not. Now that we have actually been able to send a rover there to explore the surface of this intriguing planet, we believe now that at least there is no visible life there. The testing done by the rover and the technical gadgets it is equipped has been taking soil and rock samples to see if there might be some sort of small lifeform or water. One of the main things scientists wanted to know ... more...

I'm sure that you have, during some time your life, heard about some group of people finding some prehistoric fossil. Depending on the location or the size of the object, it could take months or even years to extract this piece of history. They will want to be able to take it out of this area in one piece. They found whole animals frozen in ice from the Ice Age. This extraction took them years to complete because of the size and weight. They had to bring in special machines to remove... more...

It really is easy to build your own telescope, if you are so inclined. Well, we won't say easy because it really depends on what kind of telescope you want to build. It's easy to build your own telescope if you want a simple device that conveys the basic principles of a telescope. If you are wanting a fully functional telescope that you want to use to look at the night sky, it will take a little more time, effort, and expense. The first thing you need to know is what supplies... more...

An optical telescope is a telescope that is used to gather and focus light mainly from the visible part of the electromagnetic spectrum. The optical telescope allows the user to directly view a magnified image of something far away. The term is used especially for a monocular with static mounting for observing the sky. There are three primary types of optical telescope: * Refractors which use lenses * Reflectors which use mirrors * Combined Lens-Mirror Systems which use bot... more...

Uranus and Neptune are known as the ice giants, huge blue planets located in the outer Solar System. They are similar to Jupiter and Saturn in that they are predominantly composed of gases and ice but differ in many key areas. While still dwarfing the inner planets the ice giants are smaller than the other gas giants. Due to their distance from Earth they were the last planets to be discovered, Uranus in 1781 and Neptune in 1846. Uranus is the seventh planet from the Sun and orbits betwee... more...

Saturn is the most visually striking planet in the Solar System. It is the second largest gas giant behind Jupiter and is surrounded by a spectacular series of rings. Saturn is the sixth furthest planet from the Sun at 1,400 million km away and is named after the Roman God Saturnus. The rings are made from icy particles and dust, Saturn has around 60 moons as well as the only moon with a stable atmosphere, Titan. Saturn has a small core made from ice and rock with the rest of the planet b... more...

With the prices of gasoline on the rise, and the amount of fossil fuels consumed by the United States, coupled with the effect green house gases are having on our environment, it comes as no surprise that alternative fuels in the automotive industry are being researched. We hear politicians talk about our fuel alternatives and mention electricity as a real possibility for the automotive industry. We hear things like senator McCain offering enormous amounts of incentive monies to help d... more...

The scientific world is never short on impressing us on their wonderful experiments and tricks on finding new information about our human race. One of the things that people with fish tanks will know and use are dissolved oxygen analysers. These measure the amount of dissolved oxygen in liquid and are typically measured in PPM (parts per million). Dissolved oxygen is a process that can happen in fish tanks, which very often can be as a result of algae formation. A dissolved oxygen analyse... more...

A telescope for sale today, is pretty much the same as the ones sold a hundred years ago. Though there are marked differences, the technology pretty much stayed the same. However, in the last few years, computerized GoTo telescopes have become very popular over conventional reflector telescopes. Discover more in this article. Reflector telescopes also known as a Newtonian reflector after Isaac Newton who invented it, is a telescope that operates with a mirror at one end of the telescope, ... more...
