How a type of aurora on Mars is formed

Physicists led by the University of Iowa have learned how a type of aurora on Mars is formed. In a new study, the physicists studied...

Scientists find new unexpected phenomenon in quantum physics of materials

Researchers at Northeastern have discovered a new quantum phenomenon in a specific class of materials, called antiferromagnetic insulators, that could yield new ways of...

Scientists detect an explosion on a white dwarf dead star

When stars like our Sun use up all their fuel, they shrink to form white dwarfs. Sometimes such dead stars flare back to life in...

Scientists find easier way to measure black holes in distant galaxies

Three years ago, the first ever image of a black hole stunned the world. A black pit of nothingness enclosed by a fiery ring of...

Volcanoes may have killed Venus with a runaway greenhouse, and almost the Earth too

What turned Venus into hell? It could have simply been a steadily-warming Sun, but new research suggests that Volcanoes may have played a role in...

How physics can help us make sense of multiverse madness

If you’re a fan of science fiction films, you’ll likely be familiar with the idea of alternate universes – hypothetical planes of existence with...
