Following is about Space around our globe. Same kind of comment can be applied to all Cosmic Matter. How though?
The Outer Space Treaty represented a recognition that no one can own space because once you reach orbit, you circle the globe every 90 minutes, so international boundaries disappear. That’s why it should be a place of cooperation rather than conflict. Unfortunately, space is also a place of high strategic value from a military point of view, which is why talk of space as a “war-fighting domain” is disturbing and violates the spirit of the agreement signed more than 50 years ago.
May common sense, and the spirit of that treaty prevail. (Extract from comment by Bob McDonald of CBC).
Our universe contains an amazing array of celestial objects, sometimes referred to as celestial bodies or astronomical objects. Though most of the observable cosmos is composed of empty space, this cold, dark void that is sparsely populated by a number of astronomical objects that range from the common to the bizarre. Known collectively by astronomers as celestial objects, celestial bodies, astronomical objects, and astronomical bodies, they are the stuff that fills the empty space of the universe. Most of us are familiar with the stars, planets, and moons. But beyond these everyday celestial objects, lies an amazing collection of other wondrous sights. There are colorful nebulae, delicate star clusters, and massive galaxies. Pulsars and quasars add to the mystery, while black holes swallow up every bit of matter that comes too close. And now, the search is on to identify the mysterious, invisible objects known as dark matter. Join Sea and Sky for an intriguing journey as we discover these amazing celestial objects.
