yes, ex. the sun generates heat using uv and infrared; these have to travel trough space the most vaccuum space in the universe
Yes. Radiant heat like that passed on by Electromagnetic waves, such as IR or indirectly, Microwaves.
This for the most part is how the Sun warms the earth and every thing else in the solar system. I say for the most part because as you study forms of energy transfer (both strictly heat, and different forms of energy) you will find that in a system, rarely is there a situation where only one form of energy transfer is present. Whereas they teach (at least at first) that the interplanetary space is a vacuum, it is actually full of gas and particles, albeit at an extremely low pressure. Massive particles (that is, particles that have mass, not huge particles) flung out by the sun outward are part of the solar wind, which has some influence on temperature. Those, however, would transfer heat by kinetic transfer of energy into molecular vibrational energy (heat), through a combination of conductive and convective heat transfer. However, to reiterate, radiant heat is the predominant form in this scenario.

Is it possible for heat to flow across a vacuum?
Heat needs something to "flow" through. In a vacuum it will not have a medium to travel through and so heat cannot flow across a vacuum. Radiant heat will travel through a vacuum but here it is the light energy that is passing through the vacuum, not the heat energy.
What is a mechanism that heat transfer does not need a medium to travel through?
Radiant heat (electromagnetic waves) does not require a medium. Sunlight, infrared light, microwaves are all radiant heat in the form of electromagnetic radiation.
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.
What is energy that can be transferred through empty space?
heat or light radiation can travel through a 100% vacuum
Can heat travel by convection through a vacuum?
No. Convection requires a carrier to convey the heat. Vacuum says there is nothing to do the conveying. Radiation does not need a convector, so heat can travel by radiation through a vacuum, like the radiation from the sun.

Does radiation require a heated liquid to transfer energy?
No. radiant energy (including heat) can pass though a vacuum.
Can heat travel through a vaccume by radiation only?
Rradiation is the only way that heat can travel in a vacuum.
Heat transfer by radiation is the only method of heat transfer that can travel through a vacuum. What is a vacuum?
A vacuum is a space where there is no, or very little matter (ex. air molecules). One example of a vacuum is outer space. Because there is no matter for heat to travel through via convection or conduction, radiation is the only heat transfer that can take place in 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.
What is a mechanism that heat transfer does not need a medium to travel through?
Radiant heat (electromagnetic waves) does not require a medium. Sunlight, infrared light, microwaves are all radiant heat in the form of electromagnetic radiation.
Can heat travel through vacuum?
Yes. Just look at how heat travles from space to Earth.
Can heat energy travel through space a vacuum by convection?
Actually heat cannot travel through vacuum. sun emits radiations (obviously electromagnetic radiations.) which needs no medium to travel. hence these radiations travel through space and reaches earth where it interacts with atmosphere. when these radiations fall on media like air, water land etc. the radiation is converted into heat energy. Thus it is clear that heat from sun is converted into radiations which travel through space and reaches earth where it is converted to light.
Why did the astronauts not freeze on the moon?
Good insulation is the biggest protection. The vacuum of space is an excellent insulator, the transfer of heat energy is primarily through contact and radiant heat.
