A Powerful New Lens

In 1997, the Hubble telescope took flight to give us a look through its powerful lens into places we had never known or seen before. Through this mammoth telescope, we discovered a staggering number of other galaxies out there beyond our own. Our tiny earth is just in one tiny galaxy. And our Milky Way galaxy is just a little disk-shaped spiral when compared with the expanse of other galaxies. Sure, we have our sun and moon—our little spot along with the planets that surround us. Yet the Hubble telescope revealed that we are just one of many. In other words, we aren’t quite the center of the universe we once thought we were. In fact, scientists reported that each of the 100 billion to 200 billion galaxies they believe they have discovered has up to 100 billion stars in it. And if 100 billion to 200 billion galaxies each containing up to 100 billion stars is too large for you to grasp, just consider the galaxy Andromeda. Andromeda is roughly 2.5 million light-years away from us. (Light travels at about 186,282 miles per second.) So if you had friends living in Andromeda and you sent them a message at the speed of a radio wave (which travels at the speed of light), you could receive their reply in about 5 million years. You can’t send a text message to Andromeda regardless of how intelligent your smart phone might be.
