A káosz gyermekei vagyunk, és a változás mélystruktúrája a felbomlás. Lényegében nincs semmi más, csak a bomlás és a káosz feltartóztathatatlan áradata. Célnak nyoma sincs; semmi nem maradt ezen az irányultságon kívül. Ha tárgyilagosan pillantunk az univerzum mélyébe, kénytelenek vagyunk elfogadni ezt a kilátástalanságot. Peter Atkins
The Pinwheel Galaxy is in the constellation of Ursa Major (also known as the Big Dipper). It is about 70 percent larger than our own Milky Way Galaxy, with a diameter of about 170,000 light years, and sits at a distance of 21 million light years from Earth. This means that the light we're seeing in this image left the Pinwheel Galaxy about 21 million years ago - many millions of years before humans ever walked the Earth.
A Strange Ring Galaxy: On the outside is a ring dominated by bright blue stars, while near the center lies a ball of much redder stars that are likely much older. Between the two is a gap that appears almost completely dark. How Hoag's Object formed remains unknown, although similar objects have been identified & collectively labeled as a form of ring galaxy. Genesis. Hypotheses include a galaxy collision billions of years ago & the gravitational effect of a central bar that has since vanished
The Cat's Eye Nebula or NGC 6543, is a planetary nebula in the constellation of Draco. Structurally, it is one of the most complex nebulae known, with high-resolution Hubble Space Telescope observations revealing remarkable structures such as knots, jets, bubbles and sinewy arc-like features. In the center of the Cat's Eye there is a bright and hot star; around 1000 years ago this star lost its outer envelope, producing the nebula.---Wikipedia
