9:59:59.000,9:59:59.000 One day the last star will die[br]and the universe will turn dark forever, 9:59:59.000,9:59:59.000 it will probably be a red dwarf;[br]a tiny kind of star 9:59:59.000,9:59:59.000 that is also one of our best bets[br]to find alien life, 9:59:59.000,9:59:59.000 and might be the last home of humanity[br]before the universe becomes uninhabitable. 9:59:59.000,9:59:59.000 So what do we know about them? 9:59:59.000,9:59:59.000 And why are they our last hope? 9:59:59.000,9:59:59.000 At least 70% of the stars in the Universe[br]are red dwarfs. 9:59:59.000,9:59:59.000 They are the tiniest stars out there, 9:59:59.000,9:59:59.000 with only about 7 to 15 percent of the[br]mass of our sun. 9:59:59.000,9:59:59.000 Not that much bigger than the[br]planet Jupiter, 9:59:59.000,9:59:59.000 which is still huge, though. 9:59:59.000,9:59:59.000 They are also very demn. 9:59:59.000,9:59:59.000 It is impossible to see them with[br]the naked eye. 9:59:59.000,9:59:59.000 You have never seen one in the nightsky. 9:59:59.000,9:59:59.000 Even with all our technology we can only[br]clearly absorve red dwarfs in our neighbourhood. 9:59:59.000,9:59:59.000 Approximately 20 of the 30 stars closest to [br]Earth are red dwarfs. 9:59:59.000,9:59:59.000 Like all stars, red dwarfs fuse hydrogen[br]into helium.
