But stars are always on the move--they are just so far away that the movement is hard to see. But some stars move in ways that appear to be strange to be real. In 2005, astronomer Warren Brown found one of these space oddities . It was located on the outer edge of the Milky Way, the galaxy  we live in. The star was speeding away like nothing he'd ever seen. "It seemed unbelievable. No star in the galaxy has a speed like that," Brown remembers. "I thought, oh my goodness, I have something kind of special here." No one had ever seen a star like this one. What does a scientist do when the results don't make sense? Brown didn't give up. Instead, he kept looking. And he kept finding more of these strange and speedy stars, called _ stars. Hyper means "above" and velocity has to do with speed. He and his team just found six more of these "above speed" stars, bringing to the total of 16. And, he says, he's found even more, and is just waiting for the scientific community to confirm them. Question: In 2005, astronomer Warren Brown found  _  . Options: A: a star was speeding away very fast. B: a stars was moving away very slowly. C: some stars were not real. D: some stars were not in the Milky Way.

"I really don't know unless I weigh it , " said the professor, " but , my question is : What would happen if I held it up like this for a few minutes?" " Nothing , " the students said. "OK, what would happen if I held it up like this for an hour?" the professor asked. "Your arm would begin to ache, " said one of the students. "You are right, now what would happen if I held it up for a day?" "Your arm could go numb  , and you might have to go to hospital, " another student said. "Very good ! But during all this, did the weight of the glass change?" asked the professor. "NO" "Then what made the arm ache and the muscle( ) stress?" The students were puzzled. " Put the glass down" said one of the students. "Exactly ! " said the professor. " Life's problems are something like this. Hold them for minutes in your head and they seem OK. Think of them for a long time and they begin to ache. Hold them even longer and they begin to trouble you. You will not be able to do anything. It's important to think of the problems in your life, but even more important to ' put them down' at the end of every day before you go to sleep. That way, you are not stressed; you wake up every day fresh and strong and can handle any issue, any challenge that comes your way ! " ,. Question: What is the best title for the text?
