Science：Meteor shower
【明報專訊】“ Dr Panda: The sky is clear tonight! Let's go stargazing (觀星). We may even spot a shooting star!
“ Eason: If a meteor shower occurs, I will make as many wishes as I can! I'll ask for a powerful weapon and a big and destructive robot, and I'll pray for the Smarties' defeat! ” ”
“ MoMo: How silly of you! You should work hard to get what you want instead of asking any stars to let you have them! ”
When a meteor shower occurs, one sees many shooting stars in a short period of time. After a meteoroid has entered the atmosphere of the earth, the great friction (磨擦力) between it and the atmosphere will cause it to burn, and its path will leave a bright tail.
