This October Earth will be passing through the tail of Halley’s comet, which will mean a shower of meteors flashing across the night sky. Our science editor Sam Gouldson explains.
A comet is a lump of rocky particles, ice and dust all bound together like a dirty snowball. When the comet nears a star, its surface transforms from a solid to a gas. The star’s light shines through these gases and makes them visible to observers as a fuzzy cloud around the comet’s centre, and a tail streaming out behind.
When she was eight, Betty fell in love with aeroplanes. She watched them flying over her house every day, she devoured books about them, and she begged her parents to take her to airfields where she would persuade pilots to take her on rides above the clouds.
Betty must have been a very persuasive person, because she also talked a young Navy pilot into giving the whole family flying lessons. And when I say whole family, I mean it: Betty flew her first plane solo when she was just twelve years old. She might have been a tiny daredevil, but she was so scared her mother would scold her for doing it that she kept it a secret for a week!
