(CNN) Neutrinos, so-called "ghost particles" scattered across the universe, can be 10 million times lighter than the mass of an electron, according to a new study.

Neutrinos are referred to as ghostly because they are extremely volatile, or vaporous, cosmic particles that can pass through any kind of matter without changing. They have almost no mass -- but now scientists have calculated the mass of the lightest type of neutrino.

They can travel through the most extreme environments, like stars, planets and entire galaxies, and remain the same. But neutrinos, while highly energetic, have no charge. Not even the most powerful magnetic field can affect them.

Last year, scientists were able to trace the origins of a high-energy, tiny neutrino for the first time. It traveled 3.7 billion light-years to Earth. It was found by sensors deep in the Antarctic ice in the IceCube detector.

Scientists and observatories around the world were able to trace the neutrino to a galaxy with a supermassive, rapidly spinning black hole at its center, known as a blazar. The galaxy sits to the left of Orion's shoulder in his constellation and is about 4 billion light-years from Earth.
