Spherical spiral
WebStars in the bulge of a spiral galaxy tend to be older and redder than the rest. There's also a much fainter, roughly spherical, stellar halo encompassing the disk. An example of a … WebA spherical (or more usually a hemispherical) thrust bearing consists of a sphere that rotates concentrically in a spherical cup with groove patterns. The image shows the grease lubricated spiral groove hemispherical bearing invented by Ron Woolley of the Gas Bearing Advisory Service at Southampton University in collaboration with British Gas. [6]
