  Variable star - Wikipedia, the free encyclopedia
Of the brighter stars in the sky, Polaris is a Cepheid, although a somewhat unusual one.
Stars in this class are helium supergiants with a period of 0.1 - 1 day and an amplitude of 0.1 magnitude on average.
Stars with sizable sunspots may show significant variations in brightness as they rotate, and brighter areas of the surface are brought into view.

 Star Light, Star Bright...   (Site not responding. Last check: 2007-10-11)
Stars are huge masses of hot, glowing gases, made up of about 75% hydrogen, 22% helium, and traces of oxygen, neon, carbon, nitrogen, and other elements.
This energy is transferred to the surface of the star and then passed into space in the form of light, heat, and radio waves.
For example, a star that is in the late stages of its existence may have exhausted its supply of hydrogen fuel, causing it to burn helium and heavier elements.

Light from both the guide star and the faint astronomical object is reflected from a computer-controlled deformable mirror, which removes the optical distortions caused by turbulence in the earth's atmosphere.
In order to be useful as a wavefront reference, a relatively bright star must be located quite close to the astronomical target, typically within less than a minute of arc for infrared observations and within 15 arc sec for visible-light observations.
Unlike light from astronomical objects, which only traverses the atmosphere once, the laser light passes through the atmosphere twice, propagating to the sodium layer and back down to the detector.

 Star Light, Star Bright - Spectra, Spectra in the Night
As each particular kind of star has a well-defined average illumination, the distance to any particular star of a discernable type can be calculated using the simple inverse square law for the dimming of light, giving us a spectroscopic yardstick for the galaxy.
Despite the prominence of visible light in astronomical spectroscopy, ultimately all parts of the electromagnetic spectrum are proving useful for probing the physical and chemical nature of the universe.
Such light was predicted to be dimmed by the struggle against the still intense gravitational fields and was postulated to exist as a cosmic microwave background.

 Star Light, Star Bright -- Science Background   (Site not responding. Last check: 2007-10-11)
Light is a disturbance of electric and magnetic fields that travels in the form of a wave.
Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.
Stars hotter than the sun (over 6,000 degrees C) put out most of their light in the blue and ultraviolet regions of the spectrum.

 NASAexplores 9-12 Lesson: Star Light, Star Bright (Student Sheets)
Magnitude is the degree of brightness of a star.
He noted that the Earth receives 100 times more light from a first magnitude star as from a sixth; thus with a difference of five magnitudes, there is a 100:1 ratio of incoming light energy, which is called luminous flux.
Absolute magnitudes are how bright a star would appear from some standard distance, arbitrarily set as 10 parsecs or about 32.6 light years.

 Star light, star bright -- after a bit - Roanoke.com   (Site not responding. Last check: 2007-10-11)
City officials want to prevent unexpected power loss in the star by replacing almost all of its electrical components, many of which have been in use since it was built in 1949.
The $100,000 project, which will darken the star for likely the longest period in its history, is a necessity, said Gareth McAllister, facilities manager for the city.
This project comes after replacement of the observation deck at the star and will be followed by construction of a restroom facility in that area likely to start by the end of the year, said Gary Hegner, Roanoke's Parks and Recreation superintendent.

With the use of a transit to plot out a 500 foot, five point star the work on Sundance began and it was hard work since it had to be done by hand, without the use of power tools.
At first the points of the star seemed out of proportion even though the angles between points were correct according to the transit.
The light pollution problem, caused by increasing numbers of street lamps and signs, was solved by allowing each segment of the star to double in bulb capacity, up to a maximum of 184 40-watt lamps.

 SPACE.com -- Star Light, Star Bright, Do Your Planets Have Oxygen Tonight?
Because blue light is preferred by photosynthetic life on Earth, it would seem that planets orbiting hot blue stars would have the greatest amount of photosynthesis.
They also have very long lifetimes M stars, for instance, are thought to last for a hundred billion years or longer (well beyond the present age of the universe!).
Photosynthesis on Earth requires eight photons of visible light to produce one molecule of oxygen, whereas twelve to sixteen photons of light beyond the visible range would be needed to carry out the same task in a modified version of photosynthesis.

G stars are characterized by the presence of metallic lines and weak hydrogen.

According to Wolstencroft and Raven, the amount of UV radiation produced by a star is a major limiting factor to photosynthesis development.

 Wired News: Star Light, Star Bright
Stars are millions of times brighter than planets, causing glare so bright it washes out the view for astronomers trying to observe planets in other solar systems.
Previously, astronomers could only predict that other planets were orbiting stars by measuring the "wobble," or the gravitational movement, of the star.
The astronomers at CAAO used the Multiple Mirror Telescope and a technology called "nulling interferometry" to block the light of the red star Betelgeuse -- a supergiant star in the nearby Orion constellation -- to reveal the dust cloud revolving around it.

Because neutral hydrogen absorbs light energy -- unlike most of the hydrogen in our present universe, which is ionized -- the universe entered the phase of relative darkness astrophyscists refer to as "the dark ages."
There were no stars, and if there had been, their light wouldn't have traveled far.
Stars formed, radiating energy that ionized hydrogen, and the universe became transparent.

However, the stars we see are not necessarily where we think they are, according to an international research team.

It takes about 50 million years, which from the point of view of stellar lifetime or the age of the universe is almost instantaneous." If the universe is a 45-year-old person, says Gnedin, reionization happened when she was two-years-old and took about two months.
Almost immediately after reionization, stars begin to gather in small groups, forerunners of present-day galaxies.
Drawn by each other's gravity, some of these protogalaxies merge, and in the swirling tango of merger, some of their gas breaks away, thrown into space at high velocities.

We all have that connection to the inner light, and when "trained" in meditation, or when one's third eye has been opened either by a teacher or master, or through meditation or other processes, we all can see and connect with our inner light.
Some of our bodies are letting the light shine through more readily, while other bodies have become dense, either physically or energetically, and the light is not getting through as often as it could.
We tend to let our light be dulled by the events in our lives, by the attitudes of others, by what people say or do, by the many details of daily living.
