Electromagnetic radiation travels very well through a vacuum. EM radiation doesn't need a conductor, or any kind of "medium" to travel through.
Back before about 1905, scientists couldn't imagine how a wave could travel without something to travel IN, so they imagined a sort of medium that extended throughout space. They called it the "ether", and conducted countless experiments to determine the properties of the "ether". Two scientists named Michaelson and Morely tried in vain to measure the properties of the "ether", and which way the Earth was moving through it.
In 1905, Einstein's law of special relativity demolished the very concept of "ether" as a medium of electromagnetic radiation.

Is radiation the only form of heat transfer that is unable to travel through the vacuum of space?
No. You got it exactly backwards.
Can heat travel through vacuum?
Yes. Just look at how heat travles from space to Earth.
Does the Energy from the core of the Sun first travel slowly through the convection zone and then much faster through the radiation zone?
No
What is the medium that connects the receiver to the transmitter?
Any number of things can stand between a transmitter and receiver and "connect" them. If we're talking about electromagnetic radiation (like radio waves), these signals can move through the vacuum of space, through air, or through a number of other materials. Metals and other substances that are good conductors will be resistant to penetration by or will stop radio waves. The frequency of the electromagnetic radiation will have something to do with what it will "go through" to allow it to be "connected" to a receiver.There is one thing to remember in parting: electromagnetic radiation does not need a medium through which to travel. It carries the energy of the radiation "with it" when it goes. That allows this form of energy to move through the vacuum of space. Compare this to something like a sound wave, which is mechanical energy. With waves that are mechanical energy, the medium through which the wave moves must carry the energy of that wave. Said another way, the source of the mechanical energy must put its energy into the medium for that medium to propagate the wave.
How can astronauts hear each other in spacecraft?
In space, there is no wind or something to carry the sound waves. Sound waves must travel for people to hear. For example, if an explosion took place in space, you will not hear anything because the sound waves created by the explosion won't travel.
Can radiation travel through a vacuum?
Yeah, radiation can travel in vacuum and a practical example of it is the radiation of sun coming to earth and traveling through space.
Why can radiation travel in a vacuum?
yes as radiation travels from the sun through a vacuum to earth
Radiation can travel through space which is a?
vacuum
Can heat radiation travel through a vacuum?
Yes, think of the radiation from the Sun, it must travel through the vacuum of space to warm our own planet Earth.
Does radiation require a heated liquid to transfer energy?
No. radiant energy (including heat) can pass though a vacuum.
Is a vacuum a good insulator?
Yes, vacuums prevent 2 of the 3 main sources of heat transfer; convection and conduction. Heat can still travel accross a vacuum by radiation though.
What is the broad band of energies that can travel in a vacuum?
Electromagnetic Radiation
Do infrared waves travel through a vacuum?
Yes, infrared waves are part of the electromagnetic radiation spectrum and all electromagnetic radiation will propagate through a vacuum.
Can radiation travel though space?
All types of radiation can travel through space.
What does sound travel though?
A vacuum.
Can heat travel through a vaccume by radiation only?
Rradiation is the only way that heat can travel in a vacuum.
What can light travel threough?
Light is an electromagnetic radiation that travel through air, vacuum, glass, plastics, ,,,
