1.Our galaxy, the Milky Way, has a diameter (proper length) of about 1.2 105 light-years. As far as an astronaut is concerned, how long (in years) would it take to cross the Milky Way, if the speed of the spacecraft is 0.99549c?2.A law enforcement officer in an intergalactic "po...

But what he hadn’t reckoned on was Jim giving him two rapid hard strokes in quick succession. The pain of two strokes winded Stewart almost at once, and his hands flew back to grab and soothe his sore, blazing arse. “Get your hands out of the cane’s way! Right now!” shouted ...
Most of these numbers are approximate. Galaxies do not have precise boundaries - the stars slowly become less plentiful as you move away from the galaxy. Properties of the Milky Way Diameter of the Galaxy 90 000 light years Classification of the Galaxy SBbc Number of stars in the Galaxy 200...

For starters, the Milky Way is a disk about 120,000 light years across with a central bulge that has a diameter of 12,000 light years (see theGuide to Spacearticle for more information). The disk is far from perfectly flat though, as can be seen in the picture below. In fact, it ...
It lies on the far side of the galaxy from us and is heavily obscured by the intervening gas, dust and stars. It is approximately 78000 light years away and about 10000 light years in diameter. It is orbiting our galaxy in a period of about 1 billion years but it cannot be expected ...
the diameter of the galaxy with any degree of accuracy. Various models of what the Milky Way might look like when seen from outside of the galaxy have all yielded size estimates of around 100,000 light years, but a new study has just doubled this value to about 200,000 light years. ...

Since the birth of modern astronomy, scientists have sought to determine the full extent of the Milky Way galaxy and learn more about its structure, formation and evolution. At present, astronomers estimate that it is 100,000 to 180,000 light-years in diameter and consists of 100 to 400 bil...
