Using a phenomenon known as gravitational lensing, it might be possible to use the sun as a gigantic telescope to peer deep into space.

Cosmic dust may have helped to kick-start life on Earth, new research suggests. The findings challenge a widely held assumption that this was not a plausible explanation.
