Star Trek: Voyager is the fourth live-action Star Trek series. It was created by Rick Berman, Michael Piller and Jeri Taylor, and ran on UPN (as UPN's first ever series) for seven seasons in the USA, from 1995 to 2001.

 


Star Names - What Do They Mean?
Do you know the meaning of star names? When you want to know the names of the stars and what they mean you can easily look them up online but here are some of the ones that you may be interested in or have heard before.

A star of spectral type A, white in color, with a spectrum dominated by the Balmer series of hydrogen. Lines of heavy elements, such as iron, are noticeable at the cooler end of the range.

STAR, the general term for the luminous bodies seen in the heavens; used also by analogy for star-shaped ornaments (see Medal; Orders and Decorations) or other objects, and figuratively for persons of conspicuous brilliance.

Star Cluster
Related Category: Astronomy: General
a group of stars near each other in space and resembling each other in certain characteristics that suggest a common origin for the group.

Star clusters are groups of stars which are gravitationally bound.

Star hopping involves "hopping" from star to star with your telescope, until you arrive at the location of the target object.

Star Art - An Introduction to Myths of Different Cultures
Star watching has occupied humans from the earliest times. Our ancestors studied the night sky and saw shapes and patterns among the stars. They often made up stories to explain what they saw.

Star clusters are groups of stars which are close together in space, rather than just accidentally lined up one behind the other. There are several different kinds.

Star
A gravitationally bound ball of mostly hydrogen and helium gas which is self-luminous from internal nuclear fusion reactions. Stars can vary in composition and mass, with their radius and luminosity depending on mass and age.

Star maps show Aquarius as a young man pouring water from a jar, although Ovid, in his Fasti, says it is a mixture of water and nectar, the drink of the gods. The stream ends in the mouth of the Southern Fish, Piscis Austrinus. But who is Aquarius?

Star classification
There are different classifications of stars ranging from type O which are very large and bright, to M which is often just large enough to start ignition of the hydrogen.

The star itself is Sirius. The brightest star in the sky, Sirius is also known as the "dog star". This is because it is in the constellation of Canis Major, or the Great Dog. It's name comes from Arabic, meaning "the scorched one".

Once a star such as our Sun has formed its heat will begin to affect the remaining gas disk. The temperature in the disk will be highest near the Sun and lower as one goes out. This is consistent with the trend (6) in composition for the planets.

A multiple star consists of three or more stars which appear from the Earth to be close to one another in the sky.

Choose a bright star within 10 to 20 degrees of the equator lying near the meridian. Now align your crosshairs west and east. More accurately, shut the drive off and align the crosshairs so that the star drifts parallel to one of the hairs.

The first clue that there was a neutron star at this location came in 1992, when the ROSAT (the Roentgen Satellite) found a bright X-ray source without any optical counterpart in optical sky surveys.

A star of spectral type A with a surface temperature of about 10,000 K, in whose spectrum the Balmer lines of hydrogen attain their greatest strength. Helium lines can no longer be seen.

Open star clusters are groups of stars which formed from the same huge cloud of gas and dust. They are usually made up of groups of tens to hundreds of younger stars and are found in irregular galaxies and in the spiral arms of spiral galaxies.

Star Factory
Thousands of stars have been born from this vast cloud of gas and dust known as the Carina Nebula, and thousands more are taking shape today.

STAR CLUSTERS
Open clusters are found in the disk of the Galaxy, and therefore lie largely in the plane of the Milky Way. Many of the closer ones, including those presented here, are easily visible to the naked eye (Messier 35 a fainter exception).
