... of galaxy formation. But the objects are so faint that their true nature can only be explored with the advanced telescopes of the future."
"This observation is a major step toward fulfilling one of Hubble's key objectives: to search for the faintest and farthest objects in the universe," adds Ed Weiler, NASA's acting Associate Administrator for Space Science.
In a separate discovery, Thompson also found that faint red galaxies matched up with compact blue knots of light seen in the earlier visible light image. "This means that some objects that appeared to be separate galaxies in the optical imag ...

The Water And The Waves
Number of Words: 351 / Number of Pages: 2
... for ourselves by passing
it through a prism, or even through a jug of water, or as Nature
demonstrates to us when she passes it through the raindrops of a summer
shower and produces a rainbow. We also know that light consists of waves,
and that the different colors of light are produced by waves of different
lengths, red light by long waves and blue light by short waves. The
mixture of waves which constitutes sunlight has to struggle through the
obstacles it meets in the atmosphere, just as the mizture of waves at the
seaside has to struggle past the columns of the pier. And these obstacles
treat t ...

Where Do We Draw The Line?
Number of Words: 1239 / Number of Pages: 5
... of bringing all life processes under control. We must step carefully into this vast new field of science with the understanding that putting a patent on the melanoma gene or the baldness gene for that matter is simply playing God in a potentially dangerous way.” (Appleyard, Bryan, Jan 98, Smithsonian)
These are only a few examples of scientific developments that in my mind raise the question: in science? Mr. Appleyard could not have been more on point in his allusion to Aldous Huxley’s novel “Brave New World” which along with Mary Shelley’s novel “Frankenstein” raises the same question regardi ...

Gold
Number of Words: 305 / Number of Pages: 2
... or sealing of an astronaut's helmet. Gold is also a very good
conductor of electricity.
As you can see, gold is an element that is not only a great gift
for someone, but is very usefull if actually put to use. The main drawback
to gold is that it is a very precious metal. We dont have an unlimited
supply of it. This is why gold today is priced so high and really doesn't
drop that much over time. ...

The Dust-Cloud Hypothesis
Number of Words: 318 / Number of Pages: 2
... dust that
was to become the earth. The gas expanded, and some of it flowed away into
space. The dust that remained behind then collected together because of
gravity. Although the shrinking earth generated a lot of heat, most of
this heat was lost into space. Therefore, the original earth was most
likely solid, not molten.
This hypothesis was developed by a scientest, Harold C. Urey in 1952. It is
also known as the Urey's hypothesis. He showed that methane, ammonia, and
water are the stable forms of carbon, nitrogen, and oxygen if an excess of
hydrogen is present. Cosmic dust clouds, from which t ...

Abortions
Number of Words: 711 / Number of Pages: 3
... but it might take some time. My plan calls for the closing and the illegalizing of abortion clinics, and the prosecution of people who perform these deeds.
As with any big descion we must consider the opposing views. One reason that the debate on what we should do about doesn’t go anywhere, is because each side focuses on a different topic. We make no progress because we are not talking about the same thing. The anti-abortionists are focused on the fetus’ rights, and the pro-abortionists are focused on the women’s rights. Though these issues are basically interrelated, they are different topics ...

Invertebrate Vs Vertebrate
Number of Words: 1297 / Number of Pages: 5
... adult larvae stage, the hermit crabs begin looking for a shell to live in. Once they mature and find a suitable shell, they come to live on land for the rest of their lives. Hermit crabs grow on land by shedding their exoskeleton. It takes about ten days for a hermit crab's skin to harden after molting. Shedding is a necessary part of their livelihood since they will grow back missing legs during this time. In the wild, hermit crabs can live up to 25-30 years. But normally in captivity they live around 1 year.
Hermit crabs can eat a variety of foods. In the wild they are scavengers and will eat about ...

UFO's

... aircraft flying in formation. According to his estimate the aircraft
were approximately the size of a DC-4 airliner ( Jackson 4).
This account was the first sighting to ever receive a great deal of
media attention. This sighting gave birth to the phrase "flying Saucer" coined
by a reporter named Bill Begrette. Although not the first UFO sighting in
history, Kenneth Arnolds account is considered to be the first documented UFO
sighting.
The following day Mr. Arnold discovered that in addition to his
sighting there were several others in the Mount Ranier area that same day

Solar Cells
Number of Words: 1104 / Number of Pages: 5
... In electrical conductors,
these bands are continuous but in insulators and semiconductors there is an
"energy gap", in which no electron orbits can exist, between the inner valence
band and outer conduction band [Book 1]. Valence electrons help to bind together
the atoms in a solid by orbiting 2 adjacent nucleii, while conduction electrons,
being less closely bound to the nucleii, are free to move in response to an
applied voltage or electric field. The fewer conduction electrons there are, the
higher the electrical resistivity of the material.
In semiconductors, the materials from which sola ...

The Big Bang

... in the past, nor will there be change in the
future. This model assumes the perfect cosmological principle. This principle
says that the universe is the same everywhere on the large scale, at all times.
It maintains the same average density of matter forever.
There are observational evidences found that can prove the Big Bang model is
more reasonable than the Steady State model. First, the redshifts of distant
galaxies. Redshift is a Doppler effect which states that if a galaxy is moving
away, the spectral line of that galaxy observed will have a shift to the red end.
The faster the galaxy move ...
