What Is Dark Matter? | NASA Space Place – NASA Science for Kids
Dec 5, 2024 · Dark matter is stuff in space that has gravity, but it is invisible and isn’t like anything else we know about. Dark matter makes up about 27% of the universe. Dark energy makes up roughly 68% of the universe.
Dark Matter - NASA Science
The mission will measure the locations and quantities of both normal matter and dark matter in hundreds of millions of galaxies. Throughout cosmic history, dark matter has driven how stars and galaxies formed and evolved.
Hubble Dark Matter - NASA Science
Hubble has played a major role in helping map the presence of dark matter throughout the cosmos, including the creation of a three-dimensional map that offered the first look at the web-like large-scale distribution of dark matter in the universe.
NASA’s Fermi Finds Possible Dark Matter Ties in Andromeda Galaxy
Feb 21, 2017 · NASA’s Fermi Gamma-ray Space Telescope has found a signal at the center of the neighboring Andromeda galaxy that could indicate the presence of the mysterious stuff known as dark matter. The gamma-ray signal is similar to one seen by Fermi at the center of our own Milky Way galaxy .
