No one can play Gruntz all the time, so what do gruntzerz do when they are not playing gruntz? Here is something i like to work with: It is a little known fact that ALL the pictures that the Hubble telescope has taken during the years (as well as pictures from other telescopes) are available on the Internet  I am not just talking about finished pictures that you can see in any science magazine - no these pictures are raw files, waiting to be processed by anyone with the time and talent to make beautiful pictures of them. The only thing ESO (the organization behind Hubble) demands is that they are given credit for the pictures if they are published. I have done a few myself, here are the best - enjoy: Two impressive "butterflies of the stars": img510.imageshack.us/img510/2346/planetarisk1dr7.jpgimg146.imageshack.us/img146/8241/planetarisk2kt7.jpg"The Pillars of Creation": img139.imageshack.us/img139/2037/pillarssc6.jpg(pictures provided with ESO)PS: You can get also get the raw files sent on CD or DVD - and that is free too  |

Now these are some amazing pictures! I know the first two are some sort of galaxies or milkyways, but what is the thrird picture? |

Wow, such incredible things, such impressive pictures! But I also can't recognize the third one.  ILoveGruntz (I do, but I'm talking to the member ILoveGruntz  ), could you explain us? |

The "Pillars Of Creation" are part of the Orion Nebula (I believe), in the area of the Horsehead Nebula. They are approximately 300 light years (for the longest column) long. The Orion Nebula is the birthplace of hundreds of young, very hot stars (mostly class O and B giants) averaging about 20 times the mass of our sun.

Wow. Didn't understand a word you said. (kidding, I got some small part of it ) A light year is approximately 6,000,000,000,000 miles (the distance than light will travel in one Earth year), so the pillar is approximately 1,800,000,000,000,000 miles in length. The star Alpha Centauri A is about 4.2 light years away ... 25,200,000,000,000 miles. Voyager is currently travelling at approximately 37,000 miles per HOUR ... so don't hold your breath for it to encounter another star. |

Correction - The Pillars of Creation is a part of the Eagle Nebula. Such nebulae are the birthplace of many different kind of stars. Usually there are lots of small stars, even though some nebulae contains a great number of big stars too. The formations you see are created by the light of one big O (or is it a B  ) class star "blowing away" the gasses. The shape of the formations are determined by hubs of small stars, that partially blocks the light of the big star. You can make the same effect by placing some sand and a few stones on a table, and then carefully blow away the sand. The other two pictures are planetary nebulae - the remains of small dead stars. |

That's weird! I just did a standard quote, and did no edit of the quoted material. So I haven't a clue as to where 'grumley' came from.  |

It seems to only be happening with me... also, you should have had no idea of where 'SwordGrunt' came from. It should appear 'guiguigrumley' in the post, my username, and appear 'SwordGrunt' in the post. Wow... |

The Tarantula Nebula: img255.imageshack.us/img255/1220/tarantula2nt5.jpgI am really annoyed that imageshack only lets me upload pictures under 1,5 MB in size. In the PNG version i have on my computer, this image is 5 MB (does anyone know a site that will host larger pictures?). Never mind, this picture is great anyways. I made it from 4 sets of 16 pictures, meaning a total of 64 pictures , that have been combined to make this massive panorama of the nebula. The black areas represent the parts that wasn't on any of the pictures. |

Does the planetary nebula in the northwest corner have a catalog number? That is a marvelous picture of the Tarantula! I have never noticed the planetary in any picture published in Astronomy or "Sky & Telescope" (I am a subscriber to Astronomy) ... so this is indeed a very detailed picture.

I don't exactly know what that "bubble" in the corner is. I really don't think that it is a planetary nebula, as it is much too large. It also lacks the symmetrical pattern of a planetary nebula.
I think that it is simply a special looking bubble of gasses - but I am not sure.
