Look for the charioteer constellation, Auriga, along with two easy-to-locate star clusters, M41 and M47. And watch as Jupiter and Venus get close.

This visual reveals how the magnetic field associated with the Psyche spacecraft distorts the ambient magnetic field to be measured.

The Psyche spacecraft includes many unavoidable magnetic field sources, which must be accounted for to measure the magnetic field signature of the Psyche metal-rich asteroid.

An annular solar eclipse creates a "ring of fire" around the Moon, similar to that seen in this image taken by JAXA/NASA Hinode spacecraft.

An annular solar eclipse over New Mexico.

An annular eclipse occurs when the Moon eclipses the Sun while it is at its farthest point from Earth, making it appear too small to block out the entire solar disk.
