Astronomers use many methods to determine this number, including gravitational lensing, the universe’s expansion rate, and more.

Earlier this week, the Sun unleashed a flurry of plasma and magnetic fields, or coronal mass ejection, at interstellar object ...

They linger in our water, our blood, and the environment—"forever chemicals" that are notoriously difficult to detect.
