National Aeronautics and Space Administrion

Since its inception in 1958, NASA has accomplished many great scientific and technological feats in air and space. NASA technology also has been adapted for many nonaerospace uses by the private sector. NASA remains a leading force in scientific research and in stimulating public interest in aerospace exploration, as well as science and technology in general. Perhaps more importantly, our exploration of space has taught us to view Earth, ourselves, and the universe in a new way. While the tremendous technical and scientific accomplishments of NASA demonstrate vividly that humans can achieve previously inconceivable feats, we also are humbled by the realization that Earth is just a tiny "blue marble" in the cosmos. Check out our "Thinking About NASA History" folder online as an introduction to how history can help you.

Space Is So Empty That If Two Galaxies “collide”, Very Little Would Be Destroyed"

You may have heard that at some point in the future, our galaxy will collide with our nearest neighbor, the Andromeda galaxy. This may conjure images of exploding stars and planetary crashes on a massive scale, but the reality is much more tame. Despite the fact that galaxies are filled with stuff, space is huge. It’s really unbelievably spread out, and that means that there are millions of miles between everything. When the collision happens, it’s very unlikely that objects from one galaxy will strike objects from the other. Instead, they’ll simply meld together into one glorious new galaxy."https://www.highpointscientific.com/astronomy-hub/post/astronomy-101/10-astronomy-facts-every-stargazer-should-know
