They study visible light by using optical telescopes.

Two invisible radiations from outer space which can affect humans are the infrared rays and the ultra-violet rays.
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.
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.

Heat is transferred through space by electromagnetic radiation, in the form of infrared radiation. This type of heat transfer does not require a medium (such as air or water) and can travel through the vacuum of space. Objects with higher temperatures emit more infrared radiation, which is then absorbed by cooler objects.
Heat can be transferred by radiation even if the objects are not touching. Radiation is a form of energy transfer that can occur through empty space, so it does not require direct contact between objects. Objects can exchange heat through radiation by emitting and absorbing electromagnetic waves.
Radiation is the transfer of heat energy through space by electromagnetic radiation. Most of the electromagnetic radiation that comes to the earth from the sun is invisible. ... In electromagnetic radiation, its frequency is the number of electromagnetic waves moving past a point each second.
Detecting radiation from space, including X-rays and gamma rays, allows scientists to gather information about high-energy processes, such as black holes and supernovae, that are invisible in ordinary light. This helps provide a more complete understanding of the cosmos and allows for the discovery of new phenomena and objects that would otherwise remain hidden.
all objects emit electromagnetic radiation through empty space, as well as matter. So feel the heat from the electric heater due to radiation.

Objects in space that emit infrared radiation include planets like Jupiter and Saturn, stars like red giants and brown dwarfs, dust clouds, and galaxies. These objects emit infrared radiation due to their temperature and composition, which allows astronomers to study them using infrared telescopes.
