The magnetic fields that formed in the very early stages of the universe may have been billions of times weaker than a small fridge magnet, with strengths comparable to magnetism

In a breakthrough study published in Nature Astronomy, researchers have discovered a new origin for some of the fastest stars ever observed: hypervelocity white dwarfs—compact stellar remnants hurtling through space

Life is complicated, and not just in a philosophical sense. But one simple thing we know about life is that it requires energy, and to get that energy it needs
