Most materials exhibit any or all of these three behaviour patterns, depending on the time scale involved in the application of the stress and the observation of its effects. Even mountains would be observed to exhibit this liquid like behavior if the time scale of observation were extended far enough.

APOD: 2009 August 22 - The Gum Nebula

The Gum Nebula 450 light-years from the front edge and 1,500 light-years from the back edge of this cosmic cloud of glowing hydrogen gas. Covered in this 41 degree-wide mosaic of H-alpha images, the faint emission region is otherwise easy to lose against the background of Milky Way stars...

A number of times in recent weeks a bright, unblinking light has appeared in the night sky of the nation's capital: a spaceship. Longer than a football field, weighing 654,000 pounds, the spaceship moved swiftly across the heavens and vanished.

The Gum Nebula

Posted: 22 Aug 2009 06:06 AM PDT

The Gum Nebula Named for Australian astronomer Colin Stanley Gum (1924-1960), The Gum Nebula is so large and close it is actually hard to see. In fact, we are only about 450 light-years from the front edge and 1,500 light-years from the back edge of this cosmic cloud of glowing hydrogen gas. Covered in this 41 degree-wide mosaic of H-alpha images, the faint emission region is otherwise easy to lose against the background of Milky Way stars. The complex nebula is thought to be a supernova remnant over a million years old, sprawling across the southern constellations Vela and Puppis. Sliding your cursor over this spectacular wide field view will reveal the location of objects embedded in The Gum Nebula, including the Vela supernova remnant.
