GRACE, GRACE-FO Satellite Data Track Ice Loss at the Poles

Greenland and Antarctica are melting - but how quickly and which areas are most affected? Nearly 20 years of satellite data provide key insights into these questions.

Greenland's Steenstrup Glacier, with the midmorning sun glinting off the Denmark Strait in the background. The image was taken during a NASA IceBridge airborne survey of the region in 2016.

A New Theory of Magnetar Formation for Neutron Stars

Figure 1: 3D snapshots of the magnetic field lines in the convective zone inside a newborn neutron star. Inward (outward) flows are represented by the blue (red) surfaces. Left: strong field dynamo discovered for fast rotation periods of a few milliseconds, where the dipole component reaches 1015 G. Right: for slower rotation, the magnetic field is up to ten times weaker.
