according to the scientists. One of the closest and most promising extrasolar systems, called Gliese 581, has twoplanetswith the apparent, possible capacity to host complex biospheres. The distance from Earth to Gliese 581 is about

(One astronomical unit is the distance between Earth and the sun— about 93 million miles, or 150 million kilometers). But how dramatic those effects will be is still up in the air. "The biggest question probably is, Will there be fireworks or not?" Meyer said. "We still don’t know...
The Andromeda galaxy is the closest spiral galaxy to the Milky Way and is about 2.5 million light-years away (a light year is the distance light can travel in one year). The largest spiral galaxy is NGC 6872, which is 522 light-years across from the tip of one arm to the opposite ...
Where is Earth in the Milky Way? Earth is located roughly halfway to the edge of the Milky Way, at a distance of about 26,000 light years from the center. We reside in a feature known as the Orion Spur (sometimes also called the Orion Arm), which is an offshoot between the larger...
