Shock waves in the clouds of gas surrounding an exploding star (as in this artist’s depiction) accelerate charged particles called protons to very high speed, creating cosmic rays.

New evidence links origin of these very energetic particles to massive explosions of distant stars]]> Here we go!

Scientists recently reported that they’d made a mistake in a 2004 study that found the element was a supersolid. Turns out helium as a solid isn’t so super. Caption: Pslawinski

An exciting discovery in physics turns out to be merely a case of mistaken identity]]> As a gas, helium glows yellow-pink when an electric current is added.
