The first in situ measurement of the pressure at the edge of the solar system reveals that there’s still a lot we don’t know about what sets the size of the heliosphere.
Earth’s not the only thing that shakes and quakes and goes around the Sun. Not by a long shot.
This month we look around our solar system—and much farther—as we celebrate AGU’s Centennial.
Data from the Cassini and Voyager spacecraft reveal new information about the Sun’s magnetic bubble.

A regular alignment of the planets—no, it’s not pseudoscience—makes a strong enough tug to regulate the Sun’s 11- and 22-year cycles.
A new study suggests alternative explanations for Io’s unusual magnetic field.
The flyby of Ultima Thule on New Year’s Day will give us our first glimpse of a mysterious Kuiper Belt object.
The newly plotted moons of Jupiter include one “oddball” that orbits in the wrong direction and may be the remnant of a head-on collision.
Pancaking and erosion can explain a lot of the structural change in magnetic flux ropes as they fly evolve during their supersonic flight through the inner solar system.
