Capturing an image of an atom is difficult enough, but an atom's shadow? Considering that the wavelengths of visible light dwarf the size of atoms by orders of magnitude, one might think that it ...

The nucleus is very small compared to the atom as a whole: as electrons are even smaller, most of an atom is empty space the diameter of a nucleus can be 100,000 times less than the diameter of an ...

Scientists have captured the first ever photo of an electron’s whizzing orbit within a hydrogen atom, thanks to a unique new microscopy technique. Seeing inside the tiniest bits of matter is a ...

A relatively new technique for studying atoms might shed more light on how life began on Earth. Scientists have used 3D atom mapping (specifically, atom probe tomography) to discover that the oldest ...

If you expanded an atom to the size of a baseball, what would it look like? And how would the inside look if you sliced it open? The nucleus is the atom’s central core and contains more than 99.9 ...
