Radio Brightening Around Monumental Neutron Star Collision Tells a Confusing Story

August’s landmark observation of two colliding neutron stars was incredible for its immediate impact on astronomy. It answered questions, like “where did the universe’s gold come from” and “how fast is the universe expanding?” But it left behind mysteries, too. Like, “what the hell is going on with those gamma rays?”

Colliding Neutron Star Discovery Could Solve This Mystery About Our Expanding Universe

Today, physicists across the world celebrated as telescopes and observatories on Earth and in space captured a “kilonova.” Two neutron stars collided 130 million light years away, sending gravitational waves, x-rays, gamma-rays, radio waves, and light waves to the Earth. But these events also serve as a new kind of…
