Four Galaxies in Massive Smashup

Three galaxies, the size of our own Milky Way, and a fourth that’s even bigger, are smashing into each other in an unprecedented galactic pileup. That’s the finding of a NASA telescopic survey of a cluster of galaxies about 5 billion light years from us. The report will appear in Astrophysical Journal Letters. Galaxies are known to merge. The Milky Way and the Andromeda galaxy are on a collision course that would lead to a combined galaxy in some 5 billion years. But this four-galaxy merger is the first known case of more than 2 large galaxies coming together. Kenneth Rines of the Harvard-Smithsonian Center for Astrophysics said, “Most of the galaxy mergers we already knew about are like compact cars crashing together. What we have here is like four sand trucks smashing together, flinging sand everywhere.” The grains of sand are stars. Once the merger is complete, the new galaxy will be one of the biggest known up to 10 times the size of the Milky Way.

没有救了,听了N遍还是这个样
Three galaxies of the size of our Milk Way ant forth that is even biger are smashing into each oter in an unprecedent galactic plialog? That's the finding of ...clust of galaxies about five billion light years frim us. The report will appear in an Astriphysical Journal Letters. Galaxies are known to merges the Milk Way and...galaxy are on a clision course that willl lead to a combined galaxy in some five billion years. But this four galaxies merge is the first known case of more than two large galaxies coming together. Kenneth Rines of the Harvard-smithsonian Center for Astrophysics said(quote) most of the galaxies merges we already knew about are like compackes cars crashing together. What we have is like four sand trucks smashing together, fling sand everywhere into...The grain of the sands are stars.Once the merge is complete, the new galaxy will be one of the bigest known upto ten times the size of the Milk Way.

Some studies have hinted that athletes might be better off if they can better dump off some of the heat their muscles generate. Now comes new research that adds credence to the idea that athletes indeed should just chill. Other studies have tested the idea of cooling down athletes after their workouts to improve recovery. But this study looked at the effect of chilling them before their workouts to improve performance. Scientists from a couple of German Universities put more than 50 athletes into a cooling chamber, where the temperature was a frosty minus 120 degrees. The athletes stayed in the deep freeze for 2 and a half minutes. They then did an endurance run at 90% of their maximum capacity. After 6 months, the cooled athletes showed much better results and an increased oxygen carrying capacity. The scientists think that chilling slows the inevitable rising body temperature that impedes performance. Chilling also conserves body fluids because the competitor doesn't need to sweat as much to cool down. Look for the icy athletes at the summer Olympics next year in Beijing.

Some studies have hinted that athletes might be better off if they can better dump off some of the heat their muscles generate.

But this study looked at the effect of chilling them before their workouts to improve performance.

The athletes stayed in the deep freeze for two and a half minutes. They then did an endurance run at 90% of their maximum capacity. After six months, the cooled athletes showed much better results and an increased oxygen-carrying capacity. The scientists think that chilling slows the inevitable rising body temperature that impedes performance. Chilling also conserves body fluids because the competitor doesn’t have to sweat as much to cool down. Look for (no the) icy athletes at the Summer Olympics next year in Beijing.

Some studies have hinted that athletes might be better off if they can better dump off some of the heat their muscles generated. Now comes new research that just add credence to the idea that athletes indeed should just chill. Other studies have tested the idea of cooling down athletes after they work out still improve recovery. But this study looked at the effect of chilly before they work out still improved performance. Scientists from a couple of German universities put more than 50 athletes into a cooling chamber where the temperature was frosty -120 degrees. The athletes stayed in deep freeze for two and half minutes. They then did an endurance run at 90% of their maximum capacity. After 6 months the cool athletes showed much better results and an increased oxygen-carrying capacity. The scientists think that chilly slow the inevitable rising body temperature that impedes performance. Chilly also conserves body fluids because the competitor does not have to swell as much to cool down. Look for icy athletes at the Summer Olympics next year in Beijing.

Some studies have founded that athlete might be better off if they can dump off some of the heat their musles generate. Now xome to new research that add credence to the idea that athlete indeed should just chill. Other studies has test the idea of cooling down the athletes after they are woek out to improve covery. But this study looked the effect of chilling before their work out to improve performance. Scientists from a couple of German Universities put more thatn fifty athletes into a cooling champer with the temprature was frosty minus 120 degrees. The athletes stayed in the deep freeze for two point five minutes. They then did an endurance ran at ninty persent of teh maximam capacity. Aftere six months, the ciiled athletes showed much better results and increased oxegon carrying capacity. The scientist think that chilling slow the inevidale rising body temprature that impedes performance, shilling also conserves the body fluids because the competitor does not swell to much to cool down. Look for icy athletes in summer Olympics next year in Beijing.

完成了,可能错误也很多啊:loveliness:
坚持就会有收获

我不会改变字体啊:funk:
怎么改,我再word上是大的字体,到这上面又变小了
