Lots of space objects give of some X-rays, but probably the strongest signals are from Quasars.
Uranus
A spacecraft that seems to be motionless in deep space is given some type of quick push.
Some other tools are radars which are to locate unseen objects.

Space is the vast expanse that exists between objects in the universe. It is not defined by physical matter or objects but rather as the area where these objects exist. If space were not there, there would be no distance between celestial bodies, and the universe would be a singular point with no separation between objects.
Some methods for detecting and studying dense invisible objects in space include using gravitational lensing, observing the effects of their gravitational pull on nearby objects, and studying their impact on the surrounding environment through indirect observations.
Some ways things are transported in space is by spaceship, satellites, orbiters, and similar objects.
The primary source of light for objects in space is usually stars, which emit light and other forms of electromagnetic radiation through nuclear fusion in their cores. Some objects in space can also reflect light from nearby stars or other sources, contributing to their overall brightness.
yes provided if you find owners. Most of the objects found in space so far discovered are useless and debris. However some useful planets can be owned by countries in future.
Itwhat object. Some planets do have an inner core that has iron and there is also many other objects that we have not discovered that do contain iron.
