These images feature zodiacal light — the faint, diffuse glow created by sunlight scattering off dust particles in orbit.

"The appearance of such structures sheds new light on the sorts of mathematical objects that nature is built from." ...

Symmetry has been considered an unshakable property in physics, but strange quark behavior caused it to fail in a scientific ...

An aurora forms on Mars the same way as on Earth, with energetic charged particles colliding with atoms and molecules in the atmosphere, exciting them, and causing subatomic particles called ...

This process relies on a weird quantum phenomenon. Hawking proposed that pairs of subatomic particles and their antiparticle opposites are able to pop into existence as a result of fluctuations in ...
