This illustration lays a depiction of the sun's magnetic fields over an image captured by NASA’s Solar Dynamics Observatory on March 12, 2016. The complex overlay of lines can teach scientists about the ways the sun's magnetism changes in response to the constant movement on and inside the sun. Note how the magnetic fields are densest near the bright spots visible on the sun – which are magnetically strong active regions – and many of the field lines link one active region to another. This magnetic map was created using the PFSS – Potential Field Source Surface – model, a model of the magnetic field in the sun’s atmosphere based on magnetic measurements of the solar surface. The underlying image was taken in extreme ultraviolet wavelengths of 171 angstroms. This type of light is invisible to our eyes, but is colorized here in gold.

When an active region rotated into a profile view, SDO was able to capture the magnificent loops arching above an active region (Sept. 28-29, 2016). Active region are areas of strong magnetic fields. The magnetic field lines above these regions are illuminated by charged particles spiraling along them. The images were taken in a wavelength of extreme ultraviolet light. The video covers 12 hours of activity. The Earth was inset to give a sense of the scale of these towering arches. Movies are available at http://photojournal.jpl.nasa.gov/catalog/PIA21101

Dune Field in a Southern Highlands Crater

Mars Crustal Magnetic Field Remnants

Orientation and Magnitude of Mars Magnetic Field

Sand Dune Field in Richardson Crater

This large sand sheet and dune field is located on the floor of Juventae Chasma

Situated in the southern Andes Mountains, the Payún volcanic field of Argentina is a complex landscape that formed over hundreds of thousands of years. Sprawling over 5,200 square kilometers (2,000 square miles), Payún is a massive shield volcano—a broad formation resembling an ancient warrior shield. This false-color image is a composite of observations acquired on February 7 and March 20, 2001 by the Enhanced Thematic Mapper Plus on the Landsat 7 satellite. It was made from a combination of visible and infrared light, where green indicates vegetation, black indicates lava flows, and orange is bare rock rich in iron oxides. Part of the back-arc volcanism of the Andes, Payún lies about 530 kilometers (330 miles) east from where the Nazca plate subducts below the South America plate. Not surprisingly, a volcanic zone extends over some 1,000 kilometers (600 miles) north-to-south in this region. According to a study published in 2010, the regional geology and chemical composition of the rocks indicate that the volcanic field likely formed within the past 300,000 years. The dominant feature of the volcanic field is Payún Matru, an elliptical caldera measuring roughly 9 by 7 kilometers (6 by 4 miles). Geologists surmise that the caldera formed after the old magma chamber emptied and the summit collapsed. Southwest of the caldera is a stratovolcano composed of alternating layers of compacted ash, hardened lava, and rocks ejected during previous eruptions. This stratovolcano, Payún, rises to 3,680 meters (12,073 feet) above sea level. (The entire volcanic field sits at 2,000 meters, or 6,600 feet.) The stratovolcano may be the most prominent feature in the volcanic field but it is by no means the only one. More than 300 eruptive features litter the shield volcano, most of them occupying an east-west line. West of Payún Matru is an area known as Los Volcanes, a mass of strombolian cones and basaltic lava flows. Image courtesy Michael P.

This animation illustrates Jupiter's magnetic field at a single moment in time. The Great Blue Spot, an-invisible-to-the-eye concentration of magnetic field near the equator, stands out as a particularly strong feature. The gray lines (called field lines) show the field's direction in space, and the deepness of the color corresponds to the strength of the magnetic field (with dark red and dark blue for regions with strongly positive and strongly negative fields, respectively). The animation first appeared in a Sept. 5, 2018, paper in the Journal Nature. Animation available at https://photojournal.jpl.nasa.gov/catalog/PIA23229.

This graphic compares the magnetic fields of Earth and Jupiter, characterizing the field on the surface of each planet in terms of spatial scale, with large scale to the left, and small scale to the right. The linear progression of terms characterizing Earth's field identifies a dynamo core radius at 0.54 planet radius and crustal magnetization at smaller scales. By analogy, the new Jupiter model identifies a dynamo core radius at 0.81 planet radius, in the convective metallic hydrogen just beneath a zone stabilized by helium rain. https://photojournal.jpl.nasa.gov/catalog/PIA25064

Scientists have developed a way to produce models of where the magnetic field lines are several times each day. Here we have created a time-lapse version of these models over four days (2-3 each day) to give you a peek at how these change over time. The spiraling arcs of magnetic field lines emerge from active regions and connect back to areas with the opposite polarity. The field lines are more concentrated where regions are more magnetically intense. And of course, they rotate with the rotation of the Sun.

This is an artist concept comparing the present day magnetic fields on Earth and Mars. Earth magnetic field is generated by an active dynamo -- a hot core of molten metal.

NASA's Solar Dynamics Observatory (SDO) scientists use their computer models to generate a view of the sun's magnetic field (Aug. 10, 2018). We took the opportunity to compare an extreme ultraviolet view of the sun with the same image showing the superimposed field lines. The bright active region right at the central area of the sun clearly shows a concentration of field lines, as well as the small active region at the sun's right edge, but to a lesser extent. Magnetism drives the dynamic activity near the sun's surface. Movies are available at https://photojournal.jpl.nasa.gov/catalog/PIA22662
