Want this question answered?
Because conduction and convection require particles to transfer heat. Space is a vacuum (has no particles in it) so convection and conduction cannot occur.
It's a different way to transfer heat. One object emits electromagnetic radiation (for example, infrared - though it depends on the temperature); another object absorbs it. Heat transfer through radiation can occur in empty space; with conduction and convection, that's not possible.
Radiation requires neither contact (through which conduction transfers heat) nor mass flow or movement (through which convection transfers heat). Only radiation can take place in a vacuum. Convection and conduction both require a material medium for the heat transfer to occur. Only radiation can transfer thermal energy through the vacuum of space.
conduction because there is more heat in space then there is in earth
Because in space there are no particles (this is called a vacuum), however conduction and convection require particles to work eg. solids, liquids and gases have particle arrangements. So thermal radiation has to travel through space via radiation as space is a vacuum and particle-less.

through thermal radiation, a type of electromagnetic radiation, convection and conduction could not occur because there are barely anything in space
Empty space implies radiation.
Radiation is the only type of heat transfer that can occur through vacuum (space with no particles).
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.
INSULATION IS EEPING THE HEAT INSIDE AND convection and radiation I HAVE GOT NO IEA HOPE IT HELPS :))

This proess is called conduction. The other processes are convection and radiation. Convection is the transfer of energy through movement, such as boiling water. Radiation is the transfer of thermal energy through a medium or space, such as the sun heating the earth.

Radiation can travel through empty space. The radiation in question is electromagnetic waves.
Conduction and convection badly needs material medium but radiation does not need a material medium as an essential one. It could traverse even in free space in the form of electromagnetic waves
