    1. Neutrinos travel so fast that they rarely interact with matter, passing from the core of the sun to the surface in just a few seconds.If you could detect them, the neutrinos would tell us about the conditions in the suns core.

    1. The energy produced by nuclear fusion is conveyed from the center of the sun by light particles and heat called photons. The photons then transmit light to earth.

    1. light from the sun doesn't travel to earth in a straight line and is deflected at random collisions in the different layers of the sun. Layers: Nucleus, Radiative zone, convective zone, Photosphere, chromosphere, crown.

  5. How close to the sun could astronomers send a mission before it would get to hot and cause damage?

    1. nothing can get too close to the sun without burning up. "sun-grazing" will even happen to comets that get too close which means they they will disappear in the intense heat when they get too close to the sun.
