A solar eclipse happens when the new Moon passes directly between Earth and […] Those are the sounds of cosmic attacks – massive storms on the Sun firing energy and particles into Earth’s magnetic field. Such outbursts can damage orbiting satellites, cause radio blackouts, foul GPS signals, and even knock out power grids on the surface. And there are indications that we […] The star cluster Messier 3 is a beautiful sight – a sparkly ball of half a million stars. But the view from the cluster would be even more spectacular.
