Fact: The Sun’s fuel won’t last for ever

Fact: The Sun's fuel won't last for everThe Sun is fuelled by hydrogen, fusing 620 million tons of hydrogen nuclei into helium each second. This reaction produces solar radiation, which we experience as light and heat, but which also showers us with neutrinos – tiny particles that can pass through matter.

In fact, at this very second billions of neutrinos are passing through your body. The Sun is about 4.5 billion years old and, after comparing it to similar stars in our galaxy, astrophysicists reckon it is about halfway through its hydrogen burning stage. That leaves us another 5 billion years before its fuel begins to run low.

Mars’ moon remnant of catastrophic event

According to new evidence presented in Rome, Italy, Mars’ moon Phobos is made from rocks blasted off the planet’s surface in a catastrophic event, rather than the entrenched scenario that the satellite was captured by the planet’s gravitational pull and originated in the main belt of asteroids
