There’s a particular kind of neutron star that’s called a magnetar. It’s basically a dead star that has collapsed on itself and the one of current interest is being called SGR 0418+5729 (memorable, I know). Since it’s a dead star that collapsed on itself, it’s very dense, having more mass than our sun, but only being about 20km across.

We survived Y2K largely unscathed. We survived the so-called Mayan Apocalypse of 2012. We survived the doomsday predictions of Nostradamus. And we will also survive the cosmic phenomenon of our sun reversing the polarity of its magnetic field in a few months.
Solar storms, as you know, head towards Earth once in a while to remind us about the Sun’s incredible power. The fast-moving clouds of charged particles reached our planet this week and we are extremely lucky to be on Earth and not on Mars. Studies show that the Earth’s magnetosphere makes sure that the planet is not too affected by solar storms.
