For convection current we need a material medium. But in between sun and earth there is almost vacuum. So heat transfer is mainly due to phenomenon of radiation. That too electromagnetic waves are being propagated right from the sun and stars.

Why can heat travel through space by radiation but not by conduction or convection?
Because conduction and convection require particles to transfer heat. Space is a vacuum (has no particles in it) so convection and conduction cannot occur.
Does heat travel through space by convection?
No, convection requires the movement of particles. Since space is a vacuum, there are no particles present.
Why heat can travel through space only by radiation?
there is no medium for conduction or convection. all energy must be received from radiative sources.
Which substance can heat travel through convection?
All substances.
Which type of heat transfer can only travel through fluids?
convection
Does heat energy travel through by space by convection?
No
Can heat energy travel through space by convection?
Yes it can

Why can heat travel through space by radiation but not by conduction and convection?
For conduction and convection we need a material medium. But for radiation such a meaterial medium is not necessary. So in free space radiation can pass through easily.
Can heat travel through space where there is no air?
It depends on how you want to look at it. heat can only be transferred three ways: Convection, which is transferring heat through a fluid, Conduction, which is transfer of heat through a solid, and by radiation, which is emitted light in the infrared wavelengths. radiation can travel through space just fine, but convection and conduction are right out if there isn't anything that can be heated up. Radiation doesn't require a medium, and can thus transfer heat through a vacuum.

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.
How does heat affect space?
If your talking about the majority of space which is just nothing then heat affects it through radiation. Since there is no matter to transfer heat heat cannot be transfered through conduction or convection. Like the closer you travel to the sun the hotter its going to get but not because of direct contact or matter.
Does heat travel through empty space by conduction?
No, there can't be conduction in empty space. Heat may travel through empty space through radiation, though.
