Scientists have discovered HIP 67522 b, a planet so close to its star that its orbit disturbs the star’s magnetic field, triggering violent stellar flares.

The newly discovered interstellar visitor is just the third of its kind and fascinates astronomers who hope to learn from it about galaxies far, far away.

Astronomers have spotted a new comet, moving on a trajectory that indicates that it whizzed into our solar system from interstellar space and is just passing through. It's only the third time ...
