The Sun will eventually expand to fill up most of the inner Solar System beyond Earth’s current orbit and will shine 3,000-times brighter

What will happen to our Solar System after the Sun explodes?
Arya Knowles
◼ The Sun won’t explode when it eventually dies - that’s not the fate of the G-class yellow dwarf star at the centre of our Solar System. Between 5 and 7 billion years from now, the Sun will use up all its nuclear fuel and will swell to become a red giant star. It will engulf Mercury and Venus and push Earth outwards before sloughing its outer layers of hot gas and dust to form a planetary nebula with a small white dwarf - a stellar remnant - at its centre. Life on Earth will be gone long before that happens though, as the Sun will become hot enough to boil our oceans dry around 1.2 billion years from now.
How much DNA do humans and chimpanzees share?
Sunnah Safdar
◼ Humans and chimpanzees share about 98 per cent of our DNA, making them our closest living relatives. Although the remaining two per cent might not sound like much, it translates to tens of millions of differences in our genomes.
