Question
I am satisfied with the previous answer & i like it, thanks.
Give me some details neuclear reactions in the space,what is the mass of light?
Hi Imran,
Light, and all electromagnetic radiation... radio, heat, UV, X-rays, and Gamma Rays, have no mass. That's why they travel at light speed.
The only nuclear reactions in space occur in the cores of stars. The most basic is the reaction
that our sun uses, converting about 400 million tons of bare hydrogen nuclei to 396 million tons of helium nuclei in it's core, every second. It's called the proton-proton chain, if you wish
to Google it and look it up. (My actual numbers, the tons of material, might be off a little, as that is what we memorized back in 1965... those may have changed slightly.)
Clear Skies,
Tom

Astronomy has been my hobby/pasttime for over 50 years. Currently own 3 telescopes, the largest of which is a 30 inch Newtonian truss Dob that is portable.I taught Astronomy/Meteorology at the University Level for 13 years before retiring in 1995. Being retired and home most of the time, I am able to answer all questions relatively quickly, unless it's a new moon weekend with good observing conditions. No astrology questions please, or questions about alleged UFO picture identifications.
