Astronomers watch the birth of a magnetar for the first time

Astronomers observed the birth of a magnetar, an extremely dense neutron star with the universe's most powerful magnetic fields, through a superluminous supernova's unusual flickering light pattern over 200 days.

Moon's mighty magnetic field was a 5,000-year titanium blip

Our new study suggests that the Apollo samples are biased to extremely rare events that lasted a few thousand years - but up to now, these have been interpreted as representing 0.5 billion years of lunar history. It now seems that a sampling bias prevented us from realizing how short and rare these strong magnetism events were.

The science behind why some auroras have such stunning wave patterns

Auroras are nature's most special light show: when charged particles from the sun hit our atmosphere, they can generate bright colors that dance across the night sky near the Earth's poles. Auroras can come in various forms, including bands, rays, patches and more. But why auroras form these patterns is less clear. Now, researchers say they've identified the battery that powers at least one kind of auroraaurora arcs.
