A video clip that caught my attention

Title: Why Mars Died, and Earth Lived
Content: It explains why Mars could not support life while Earth can.
  • I learnt that Mars has frozen water on it.
  • I learnt that Earth has a magnetic field around it which neither Mars nor Venus has.
  • I learnt that rocks accociated with flowing water have been found on Mars.
