Ingabe ilanga liyashisa?
Yebo ilanga liyashisa, kodwa-ke ubuso belanga cishe buyi-10,000 degrees Fahrenheit, noma njengoba umhlaba wonke ubuyokwazi, ama-degrees Celsius angu-5,500.  Nokho, enkabeni, amazinga okushisa ashisayo kakhulu, angu-27 million degrees Fahrenheit (15 million degrees Celsius) okudingekayo ukuze kulondolozwe ukusabela kokuhlanganiswa okunikeza ukushisa esikuzwayo. Lapho nje lonke i-hydrogen seliguqulwe laba i-helium ngokuhlanganiswa, ilanga ngeke lisaba nengcindezi yangaphandle futhi cishe liyoba inkanyezi yama-neutron.
