All stars give out some ultraviolet light (including our Sun, which is why we get sunburn). If the star is young and hot, it gives off quite a lot, and if old and dim, only a little. All stars give off a wide spectrum of radiation, much of it invisible to our eyes. To calculate a star's total radiation, we use what is called a bolometric measurement.
The atoms in gases can also give off ultraviolet if their electrons are sufficiently excited by cosmic radiation.
Lots of space objects give of some X-rays, but probably the strongest signals are from Quasars.
The obvious answer is "Stars".
Stars are the only objects in space that give off their own light.Other objects are visible only if a star shines on them.
The obvious answer is "Stars".

ultraviolet helps give so types of flowers with light
Some ways things are transported in space is by spaceship, satellites, orbiters, and similar objects.
All stars and stellar remnants.
GALEX detects ultraviolet (UV) radiation from celestial objects in space. It is specifically designed to study the UV emission from stars, galaxies, and other astronomical sources.
Some objects in space that give off radiation include stars, pulsars, black holes, supernovae, and active galactic nuclei. These objects emit a wide range of radiation, from visible light to X-rays and gamma-rays.
The earth, the sun, stars, and galaxies emit infrared rays.
