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.

Direct Collapse

Did you know?

Direct Collapse

"Giuseppe Lodato published a series of papers explaining how dense primordial gas clouds (essentially protogalaxies) in the early universe could have collapsed to form seed black holes with masses of 1,000 to 100,000 Suns. Normally, such clouds would have fragmented during the collapse process to form a multitude of massive stars instead of a single black hole. But under certain rare conditions, a few clouds could have collapsed to form extremely black holes."Astronomy Magazine March 2021 "How to Grow a Giant Black Hole" pp. 16-23
