Gigantic 'hole' in the sun wider than 60 Earths is spewing superfast solar wind right at us
A monstrous dark patch, known as a coronal hole, recently appeared near the sun's equator. The temporary gap enables unusually fast solar wind to race toward Earth.
Do we live in a giant void? It could solve the puzzle of the universe's expansion
One of the biggest mysteries in cosmology is the rate at which the universe is expanding. One possible explanation: That we live in a giant void in space (an area with below average density).
