23. Mai 2024 · While dark matter and dark energy are central to the Euclid. The mission has a variety of other astronomical applications. Euclid’s large-area sky map can, for instance, be used to discover faint objects and observe changes in cosmic objects, like a star changing in brightness. Euclid’s new science results include the detection of free-floating planets (planets that don’t orbit stars ...
6. Mai 2024 · What Is Dark Matter? | NASA Space Place – NASA Science for Kids. The Short Answer: 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.
