The tiny pink dot in the center of this image is a magnetar — a type of neutron star with the most powerful known magnetic fields in the Universe. If a magnetar was located a sixth of the way to the Moon (~64,000 km), it would wipe the data from all of the credit cards on Earth!

The strength of Earth's magnetic field has a value of about 1 Gauss, while a refrigerator magnet measures about 100 Gauss. Magnetars have magnetic fields of about a million billion Gauss.
