Neutrinos Provide a New Way to Probe the Cosmos

We’re figuring out how to see the cosmos in a new way. For centuries, humans learned about the universe with just their eyes, observing in visible light. We eventually developed technology to see in other wavelengths of light — infrared, X-ray, gamma ray — to discover even more about the universe. Now, thanks to two papers in Science in July, astronomers can see with neutrinos, too.
