Over the past 35 years, astronomers and scientists have created new technologies to help us make some very exciting and some puzzling discoveries about our universe. In 2007, the McNaught comet unexpectedly captured everyone's attention as it became a daytime star, the first since 1965. 20.5 light-years away, we found an Earth-like planet that could potentially have primitive life on its surface. Also in 2007, the New Horizons spacecraft captured amazingly detailed photos of Jupiter's four biggest moons, Io, Europa, Ganymede, and Callisto. As well as detailed photos of Jupiter's new red spot, a storm roughly 70% of Earth's size that began turning red in 2005. In 2004, NASA's spacecraft Cassini found numerous dark, smooth areas that are believed to be lakes on Saturn's largest moon Titan, now known as Titan's "Black Sea". We have new insight to what may happen during and after the Milky Way collides with the Andromeda galaxy in about 2 billion years in the future,. 7,500 light-years away, an 11th magnitude red giant was discovered to be one of the oldest stars ever known. Again in 2007, we discovered two unusually bright supernovas, one in May, and an even brighter one in October. In January of the same year, we were first able to map dark matter, the substance that takes up most of the universe that had never been seen before. From 1994 - 2010, the Large Hadron Collider has been under development to perform a wide range of experiments in outer space. In April of 2004, NASA's Gravity Probe B was launched, and was expected to perform the most difficult general relativity tests. With all of these discoveries and inventions, what could we possible do next? Out of these ten, the subject of dark matter and dark energy fascinates me most. While still a controversial issue, it is generally agreed that dark matter exists. Normal matter takes up only about 4% of our universe. Dark matter, however, takes up about 23% of our universe, while dark energy takes up 73%. But you never really hear about dark matter, what it is, or what it does. We know dark matter exists because of its gravitational effects on normal matter, like stars, planets, and galaxies. Dark matter does not absorb or emit light, but as light approaches a clump of dark matter, it bends around it in a phenomenon known as gravitational lensing. The more massive the clump, the more the light bends. As the light bends, the source of the light, whether it's a star or a galaxy, looks distorted, or stretched. Although scientifically we know how these stars or galaxies are supposed to look, if you look through a telescope, the object you're viewing may seem a little wider than it really is. Dark matter is an invisible substance. To map this substance, the Hubble Space Telescope performed the largest survey of the universe ever done. The survey is called the Cosmic Evolution Survey, more commonly known as COSMOS. Nick Scoville led an international team of 70 astronomers to carry out COSMOS. The COSMOS survey examines a large section of the…
The Creator’s Handiwork
There is far more to the universe than hydrogen, spheres of gas, and arguments over senseless cosmology theories. There are also wonders. The universe around us was designed by a great Intelligence. Without careful planning nothing could hold together, nothing could exist.

hrouded in secrecy, ancient mystery cults fascinate and capture the imagination. A pendant to the official cults of the Greeks and Romans, mystery cults served more personal, individualistic attitudes toward death and the afterlife. Most were based on sacred stories (hieroi logoi) that often involved the ritual reenactment of a death-rebirth myth of a particular divinity. In addition to the promise of a better afterlife, mystery cults fostered social bonds among the participants, called mystai. Initiation…
“Across The Universe” Character Astrology Signs
Amy Martin: I believe that Amy is an Aries (March 21 to April 20). An Aries is adventurous, ambitious, impulsive, enthusiastic and full of energy. They are leaders, and doesn't take command easily because they are to “take charge.” Aries are much concerned with them self, both positively and negatively. They are self-reliant but also self centered (sometimes) and concerned with their own personal advancement and physical satisfaction. When Amy…
Light and the Formation of the Universe
The “critical density” is the average density of matter required for the Universe to just halt its expansion, but only after an infinite time. A Universe with the critical density is said to be flat. In his theory of general relativity, Einstein demonstrated that the gravitational effect of matter is to curve the surrounding space. In a Universe full of matter, both its overall geometry and its fate are controlled by the…

Sleep deprivation and adolescent Sleep/Wake cycles
• The amount of sleep we require is determined by age, lifestyle and genetics.
• Partial sleep deprivation is having some sleep in 24hr period but not getting enough to meet your needs
• Total sleep deprivation going without sleep for 24 hours.

Scientific Revolution's Discoveries
Azusa Pacific Online University
August 22nd, 2014
The scientific revolution began in Europe towards the end of the Renaissance era and continued through the late eighteenth century. It was the rise of modern science during the early modern period, when developments in mathematics, physics, astronomy, biology and chemistry altered views of society and nature. It influenced the intellectual and social movement known…
Dark Side of the Universe
Would you believe me if I told everything you can see in the universe is only a small fraction of what is really out there? Well it is in fact that fraction is one third of the universe. There are two forces called dark energy which we just recently discovered and dark matter which we have some proof from but can’t actually prove. These forces have been battling since the big bang theory occurred yet neither has triumphed.
The big bang was a ripping open of time and space…
Oetzi, the Iceman
The Iceman otherwise known as Oetzi is the world’s oldest and best preserved remains of a man who lived 5,300 years ago. The Iceman was found in 1991 by two hikers in the Tyrolean Alps. This finding has continued to puzzle scientists, but with the advancements of technology, light has been shed on some parts of the mystery. With the advancements in technology, scientists have been able to reveal many facts about the Iceman. Despite using traditional methods such as typology and…
The age of the universe
Throughout modern universe astronomers can estimate the age of the universe with all different bodies that creates the universe. The universe is 13.7 billion years old and the big bang happen around 10 to 20 billion years ago by scientist estimation. The way astronomers figured out the solution was figuring out the age of the cluster stars, the age of the old white dwarf stars, the chemical elements, nebula, and finding the rate of the universe using mathematics with…
