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.

The alien planet Kepler-421b â which crosses the face of, or transits, its host star from Earth's perspective â takes 704 Earth days to complete one orbit, and thus has the longest year known for any transiting alien world, researchers said. (For comparison, Earth orbits the sun once every 365 days, and Mars completes a lap every 780 days.)
