Stars appear to twinkle and are fuzzy due to the earths atmosphere
I suppose on some atom models the electron cloud would be called "fuzzy".
3 stars
The magnetic field around an atom is typically shaped like a fuzzy cloud that surrounds the nucleus. This cloud represents the probability of finding an electron at a particular location in space. The shape of the magnetic field is influenced by the movement of electrons within the atom.
A fuzzy patch in the sky typically refers to a diffuse, cloud-like formation that may indicate the presence of nebulae or other astronomical phenomena. These patches can appear as soft, blurred areas due to the scattering of light by gas and dust particles in space. In some cases, such patches can be sights of star formation or remnants of dying stars, showcasing the dynamic nature of the universe. Observing these fuzzy patches can provide insights into cosmic processes and the life cycles of celestial bodies.
protogalactic cloud
None. An oxygen atom has a roughly spherical nucleus which is surrounded by a fuzzy cloud of electrons.
A nebula is a cloud of gas and dust in space where new stars are formed. These regions are often characterized by the presence of young, hot stars surrounded by glowing gas and dark dust.
They get pulled out by stars that are outside the the cloud. But the sun may pull a comet but that is rare
About 10 billion
