Appendix cancer occurs when healthy cells in the appendix change and grow out of control. These cells form a growth of tissue, called a tumor. A tumor can be cancerous or benign. A cancerous tumor is malignant, meaning it can grow and spread to other parts of the body. Another name for this type of cancer is appendiceal cancer.
Russian astronaut breaks record for longest time spent in space. By Nicola Harley. 12:52PM BST 12 Sep 2015. Comments. An astronaut has broken the record for the longest amount of time spent in space becoming the world's most experienced space flier. Russian cosmonaut Gennady Padalka, 57, has spent a record 879 days in space throughout his career as he return from his latest mission from the International Space Station.
Of course it depends on how fast the object is traveling. In one of the NASA Space Shuttles, about 76,526 earth years (38,263 earth years one way). 1 light-year is 5.8 trillion miles and the maximum speed of a NASA Space Shuttle is 17,500 miles per hour. The fastest unmanned space craft traveled 157,000 mph. At that rate, there and back would take only 8,500 earth years. So if you were a Mesopotamian farmer in 6,500 BC, you'd be getting home right about now.
