- Welcome to Lagoon Nebula, a three-part desktop theme creation by
- Nekbyter (c) All Rights Reserved 1997.
-
- All of Nekbyter's themes are best displayed in true color (24-bit)
- on a 800x600 screen.
-
- Because there has been a problem recently with misappropriation
- and unauthorized alteration of my themes, please read this legal
- garbage before you proceed.
-
- You are entitled to use this theme provided you do it without
- altering the major components. You may share this theme with others
- provided you do not remove this readme.txt file, that you do not
- remove my name from the wallpaper and that you do not receive
- compensation for the distribution of it. Any violation of
- the above constitutes copyright violation which is a federal offense.
- Enough said.....
-
- The three wallpapers were created from NASA photo number
- STScI-PRC96-38a, entitled "GIANT TWISTERS AND STAR WISPS IN THE
- LAGOON NEBULA." The entire photo is over 22MB in size and is available
- at www.nasa.gov. This is the text which accompanies the photo --
-
- "This NASA Hubble Space Telescope (HST) image reveals
- a pair of one-half light-year long interstellar "twisters" -- eerie
- funnels and twisted-rope structures -- in the heart of the Lagoon
- Nebula (Messier 8) which lies 5,000 light-years away in the direction
- of the constellation Sagittarius. The central hot star, O Herschel 36,
- is the primary source of the ionizing radiation for the brightest
- region in the nebula, called the Hourglass. Other hot stars, also
- present in the nebula, are ionizing the extended optical nebulosity.
- The ionizing radiation induces photo-evaporation of the surfaces of
- the clouds (seen as a blue "mist"), and drives away violent stellar
- winds tearing into the cool clouds. Analogous to the spectacular
- phenomena of Earth tornadoes, the large difference in temperature
- between the hot surface and cold interior of the clouds, combined
- with the pressure of starlight, may produce strong horizontal shear
- to twist the clouds into their tornado-like appearance. Though the
- spiral shapes suggest the clouds are "twisting", future observations
- will be needed, perhaps with Hubble's next generation instruments,
- with the spectroscopic capabilities of the Space Telescope Imaging
- Spectrograph (STIS) or the Near Infrared Camera and Multi-Object
- Spectrometer (NICMOS), to actually measure velocities. This Hubble
- picture reveals a variety of small scale structures in the interstellar
- medium, small dark clouds called Bok globules, bow shocks around stars,
- ionized wisps, rings, knots and jets. The Lagoon Nebula and nebulae in
- other galaxies are sites where new stars are being born from dusty
- molecular clouds. These regions are the "space laboratories" for
- the astronomers to study how stars form and the interactions between
- the winds from stars and the gas nearby. By studying the wealth of
- data revealed by HST, astronomers will understand better how stars
- form in the nebulae. These color-coded images are the combination
- of individual exposures taken in July and September, 1995 with Hubble's
- Wide Field and Planetary Camera 2(WFPC2) through three narrow-band
- filters (red light -- ionized sulphur atoms, blue light -- double
- ionized oxygen atoms, green light -- ionized hydrogen). This work
- is based on public data retrieved from the HST Archive, cosmic-ray
- cleaned, calibrated and combined by Adeline Caulet (Space Telescope
- European Coordinating Facility, European Space Agency).

-
- Included with the theme are logo.sys, logow.sys and logos.sys files.
- If you choose to use these startup and shutdown screens, please backup
- or rename your originals in the event you wish to reuse or restore
- them later. The logo.sys file should be placed in the root directory
- of your primary hard drive. The logow.sys and logos.sys files belong
- in the Windows directory.
-
- I hope you have as much fun using these themes as I had making them.
- Comments, suggestions and fan mail are always welcome. :-)
-
- Live long and prosper.
