The Solar Storm, at Mercury

Solar Storms, Devils, Dunes, and Gullies

Explanation: In this picture, the Sun's surface is quite dark. A frame from a movie recorded on November 9th by the orbiting TRACE telescope, it shows coronal loops lofted over a solar active region. Glowing brightly in extreme ultraviolet light, the hot plasma entrained above the Sun along arching magnetic fields is cooling and raining back down on the solar surface. Hours earlier, on November 8th, astronomers had watched this particular active region produce a not so spectacular solar flare. Still, the M-class flare spewed forth an intense storm of particles, suddenly showering satellites near the Earth with high energy protons. The flare event was also associated with a large coronal mass ejection, a massive cloud of material which impacted our fair planet's magnetic field about 31 hours later. The result ... a strong geomagnetic storm.

Using the Solar Vector Magnetograph, a solar observation facility at NASA's Marshall Space Flight Center (MSFC), scientists from the National Space Science and Technology Center (NSSTC) in Huntsville, Alabama, are monitoring the explosive potential of magnetic areas of the Sun. This effort could someday lead to better prediction of severe space weather, a phenomenon that occurs when blasts of particles and magnetic fields from the Sun impact the magnetosphere, the magnetic bubble around the Earth. When massive solar explosions, known as coronal mass ejections, blast through the Sun's outer atmosphere and plow toward Earth at speeds of thousands of miles per second, the resulting effects can be harmful to communication satellites and astronauts outside the Earth's magnetosphere. Like severe weather on Earth, severe space weather can be costly. On the ground, the magnetic storm wrought by these solar particles can knock out electric power. The researchers from MSFC and NSSTC's solar physics group develop instruments for measuring magnetic fields on the Sun. With these instruments, the group studies the origin, structure, and evolution of the solar magnetic field and the impact it has on Earth's space environment. This photograph shows the Solar Vector Magnetograph and Dr. Mona Hagyard of MSFC, the director of the observatory who leads the development, operation and research program of the Solar Vector Magnetograph.

This illustration depicts charged particles from a solar storm stripping away charged particles of Mars' atmosphere, one of the processes of Martian atmosphere loss studied by NASA's MAVEN mission, beginning in 2014. Unlike Earth, Mars lacks a global magnetic field that could deflect charged particles emanating from the Sun. https://photojournal.jpl.nasa.gov/catalog/PIA22076

Energetic particles from a large solar storm in September 2017 were seen both in Mars orbit and on the surface of Mars by NASA missions to the Red Planet. The horizontal axis for both parts of this graphic is the time from Sept. 10 to Sept. 15, 2017. The upper portion of this graphic shows the increase in protons in two ranges of energy levels (15- to-100 million electron volts and 80-to-220 million electron volts), as recorded by the Solar Energetic Particle instrument on NASA's on NASA's Mars Atmosphere and Volatile Evolution orbiter, or MAVEN. The lower portion shows the radiation dose on the Martian surface, in micrograys per day, as measured by the Radiation Assessment Monitor instrument on NASA' Curiosity Mars rover. Micrograys are unit of measurement for absorbed radiation dose. Note that only protons in the higher bracket of energy levels penetrate the atmosphere enough to be detected on the surface. https://photojournal.jpl.nasa.gov/catalog/PIA21856

NASA's Marshall Space Flight Center (MSFC) and university scientists from the National Space Science and Technology Center (NSSTC) in Huntsville, Alabama, are watching the Sun in an effort to better predict space weather - blasts of particles and magnetic fields from the Sun that impact the magnetosphere, the magnetic bubble around the Earth. Filled by charged particles trapped in the Earth's magnetic field, the spherical comet-shaped magnetosphere extends out 40,000 miles from Earth's surface in the sunward direction and more in other directions. This image illustrates the Sun-Earth cornection. When massive solar explosions, known as coronal mass ejections, blast through the Sun's outer atmosphere and plow toward Earth at speeds of thousands of miles per second, the resulting effects can be harmful to communication satellites and astronauts outside the Earth's magnetosphere. Like severe weather on Earth, severe space weather can be costly. On the ground, magnetic storms wrought by these solar particles can knock out electric power. By using the Solar Vector Magnetograph, a solar observation facility at MSFC, scientists are learning what signs to look for as indicators of potential severe space weather.

These images show the sudden appearance of a bright aurora on Mars during a solar storm in September 2017. The purple-white color scheme shows the intensity of ultraviolet light seen on Mars' night side before (left) and during (right) the event. A simulated image of Mars for the same time and orientation has been added, with the dayside crescent visible on the right. The auroral emission appears brightest at the edges of the planet where the line of sight passes along the length of the glowing atmosphere layer. The data are from observations by the Imaging Ultraviolet Spectrograph instrument (IUVS) on NASA's Mars Atmosphere and Volatile Evolution orbiter, or MAVEN. Note that, unlike auroras on Earth, the Martian aurora is not concentrated at the planet's polar regions. This is because Mars has no strong magnetic field like Earth's to concentrate the aurora near the poles. https://photojournal.jpl.nasa.gov/catalog/PIA21855

This frame from an animation shows the sudden appearance of a bright aurora on Mars during a solar storm. The purple-white color scheme shows the intensity of ultraviolet light seen on Mars' night side over the course of the event. The data are from observations on Sept. 12 and 13, 2017, by the Imaging Ultraviolet Spectrograph instrument (IUVS) on NASA's Mars Atmosphere and Volatile Evolution orbiter, or MAVEN. The aurora is occurring because energetic particles from the solar storm are bombarding gases in the planet's atmosphere, causing them to glow. A simulated image of the Mars surface for the same time and orientation is also shown, with the dayside crescent visible on the right. The auroral emission appears brightest at the edges of the planet where the line of sight passes along the length of the glowing atmosphere layer.

The purple color in this animated GIF shows auroras across Mars' nightside as detected by the Imaging Ultraviolet Spectrograph instrument aboard NASA's MAVEN (Mars Atmosphere and Volatile EvolutioN) orbiter. The brighter the purple, the more auroras were present. Taken as waves of energetic particles from a solar storm were arriving at Mars, the sequence pauses at the end, when the wave of the most energetic particles arrived and overwhelmed the instrument with noise. MAVEN took these images between May 14 and 20, 2024, as the spacecraft orbited below Mars, looking up at the nightside of the planet (Mars' south pole can be seen on the right, in full sunlight).

The specks in the sequence of images in this video were caused by charged particles from a solar storm hitting one of the navigation cameras aboard NASA's Curiosity Mars rover. The mission uses the rover's navigation cameras to try capturing images of dust devils (dust-bearing whirlwinds) and wind gusts, like the gust seen here. By chance, the gust occurred at the same time that charged particles began to strike the Martian surface on May 20, 2024, the 4,190th Martian day, or sol, of the mission. The particles do not damage the camera. Curiosity's Radiation Assessment Detector (RAD) measured a sharp increase in radiation at this time – the biggest radiation surge the mission has seen since landing in 2012.

NASA's Curiosity Mars rover captured evidence of a solar storm's charged particles arriving at the Martian surface in this three-frame video taken by one of the rover's navigation cameras on May 20, 2024, the 4,190th Martian day, or sol, of the mission. The mission regularly captures videos to try and catch dust devils, or dust-bearing whirlwinds. While none were spotted in this particular sequence of images, engineers did see streaks and specks – visual artifacts created when charged particles from the Sun hit the camera's image detector. The particles do not damage the detector. The images in this sequence appear grainy because navigation-camera images are processed to highlight changes in the landscape from frame to frame. When there isn't much change – in this case, the rover was parked &ndash more noise appears in the image. Curiosity's Radiation Assessment Detector (RAD) measured a sharp increase in radiation at this time – the biggest radiation surge the mission has seen since landing in 2012.

NASA Cassini spacecraft captured the first lightning flashes on Saturn. The storm that generated the lightning lasted from January to October 2009, making it the longest-lasting lightning storm known in the solar system.

In 2007, NASA Mars Exploration Rover Opportunity had endured a Martian dust storm and the rover team wanted to assess the dustiness of the solar panels.

NASA's Solar Dynamics Observatory (SDO) zoomed in to watch close-up the dynamics of this single active region on the sun over a two-day period (July 14-16, 2018). The loops SDO observed in extreme ultraviolet light are illuminated by charged particles spinning along the magnetic field lines above an active region. Active regions are magnetically intense areas that are pushed up to the surface of the sun from below. These regions are often the sources of large eruptions that cause solar storms, though no large eruptions seem to have occurred during this period. To give a sense of scale, these loops are rising up many times the diameter of Earth. Movies are available at https://photojournal.jpl.nasa.gov/catalog/PIA22645

During its routine yearly monitoring of the weather on our solar system's outer planets, NASA's Hubble Space Telescope has uncovered a new mysterious dark storm on Neptune (right) and provided a fresh look at a long-lived storm circling around the north polar region on Uranus (left).

This graphic indicates a similarity between 2016 (dark blue line) and five past years in which Mars has experienced a global dust storm (orange lines and band), compared to years with no global dust storm (blue-green lines and band). The arrow nearly midway across in the dark blue line indicates the Mars time of year in late September 2016. A key factor in the graph is the orbital angular momentum of Mars, which would be steady in a system of only one planet orbiting the sun, but varies due to relatively small effects of having other planets in the solar system. The horizontal scale is time of year on Mars, starting at left with the planet's farthest distance from the sun in each orbit. This point in the Mars year, called "Mars aphelion," corresponds to late autumn in the southern hemisphere. Numeric values on the horizontal axis are in Earth years; each Mars year lasts for about 1.9 Earth years. The vertical scale bar at left applies only to the black-line curve on the graph. The amount of solar energy entering Mars' atmosphere (in watts per square meter) peaks at the time of year when Mars is closest to the sun, corresponding to late spring in the southern hemisphere. The duration of Mars' dust storm season, as indicated, brackets the time of maximum solar input to the atmosphere. The scale bar at right, for orbital angular momentum, applies to the blue, brown and blue-green curves on the graph. The values are based on mass, velocity and distance from the gravitational center of the solar system. Additional information on the units is in a 2015 paper in the journal Icarus, from which this graph is derived. The band shaded in orange is superimposed on the curves of angular momentum for five Mars years that were accompanied by global dust storms in 1956, 1971, 1982, 1994 and 2007. Brown diamond symbols on the curves for these years in indicate the times when the global storms began. The band shaded blue-green lies atop angular momentum curves for six years when no global dust storms occurred: 1939, 1975, 1988, 1998, 2000 and 2011. Note that in 2016, as in the pattern of curves for years with global dust storms, the start of the dust storm season corresponded to a period of increasing orbital angular momentum. In years with no global storm, angular momentum was declining at that point. Observations of whether dust from regional storms on Mars spreads globally in late 2016 or early 2017 will determine whether this correspondence holds up for the current Mars year. http://photojournal.jpl.nasa.gov/catalog/PIA20855

This 360-degree panorama is composed of 354 images taken by the Opportunity rover's Panoramic Camera (Pancam) from May 13 through June 10, 2018, or sols (Martian days) 5,084 through 5,111. This is the last panorama Opportunity acquired before the solar-powered rover succumbed to a global Martian dust storm on the same June 10. The view is presented in false color to make some differences between materials easier to see. To the right of center and near the top of the frame, the rim of Endeavour Crater rises in the distance. Just to the left of that, rover tracks begin their descent from over the horizon towards the location that would become Opportunity's final resting spot in Perseverance Valley, where the panorama was taken. At the bottom, just left of center, is the rocky outcrop Opportunity was investigating with the instruments on its robotic arm. To the right of center and halfway down the frame is another rocky outcrop - about 23 feet (7 meters) distant from the camera - called "Ysleta del Sur," which Opportunity investigated from March 3 through 29, 2018, or sols 5,015 through 5,038. In the far right and left of the frame are the bottom of Perseverance Valley and the floor of Endeavour Crater. Located on the inner slope of the western rim of Endeavour Crater, Perseverance Valley is a system of shallow troughs descending eastward about the length of two football fields from the crest of Endeavour's rim to its floor. This view combines images collected through three Pancam filters. The filters admit light centered on wavelengths of 753 nanometers (near-infrared), 535 nanometers (green) and 432 nanometers (blue). The three-color bands are combined. A few frames (bottom left) remain black and white, as the solar-powered rover did not have the time to photograph those locations using the green and violet filters before a severe Mars-wide dust storm swept in on June 2018. https://photojournal.jpl.nasa.gov/catalog/PIA22908

This composite image presents the three most visible elements of space weather: a storm from the Sun, aurora as seen from space, and aurora as seen from the Earth. The solar storm is a corona mass ejection (CME) composite from EIT 304Å superimposed on a LASCO C2 image, both from SOHO. The middle image from Polar’s VIS imager shows charged particles as they spread down across the U.S. during a large solar storm event on July 14, 2000. Lastly, Jan Curtis took this image of an aurora display in Alaska, the visible evidence of space weather that we see here on Earth.

In this annotated, graphic of Jupiter, small, bright "pop-up" clouds rise above the surrounding features in this cyclonic Jovian storm system, dubbed the "Nautilus." The image at left, taken by the Hubble Space Telescope — which observed the storm — was taken on July 16, 2018. The Juno spacecraft's JunoCam captured the storm at higher resolution on July 16, 2018, during Juno's 13th science flyby of Jupiter. The image at right, a magnification of the JunoCam image, offers a closer view. Storms like these pop-up clouds are believed to be the tops of the extreme ammonia-water thunderclouds that produce "shallow lightning" and Jovian hailstones — or "mushballs" — high in Jupiter's atmosphere. The solar-powered Jupiter explorer launched on Aug. 5, 2011 and went into orbit around the gas giant on July 4, 2016. https://photojournal.jpl.nasa.gov/catalog/PIA24303

Caption: This image from June 20, 2013, at 11:15 p.m. EDT shows the bright light of a solar flare on the left side of the sun and an eruption of solar material shooting through the sun’s atmosphere, called a prominence eruption. Shortly thereafter, this same region of the sun sent a coronal mass ejection out into space. --- On June 20, 2013, at 11:24 p.m., the sun erupted with an Earth-directed coronal mass ejection or CME, a solar phenomenon that can send billions of tons of particles into space that can reach Earth one to three days later. These particles cannot travel through the atmosphere to harm humans on Earth, but they can affect electronic systems in satellites and on the ground. Experimental NASA research models, based on observations from NASA’s Solar Terrestrial Relations Observatory and ESA/NASA’s Solar and Heliospheric Observatory show that the CME left the sun at speeds of around 1350 miles per second, which is a fast speed for CMEs. Earth-directed CMEs can cause a space weather phenomenon called a geomagnetic storm, which occurs when they funnel energy into Earth's magnetic envelope, the magnetosphere, for an extended period of time. The CME’s magnetic fields peel back the outermost layers of Earth's fields changing their very shape. Magnetic storms can degrade communication signals and cause unexpected electrical surges in power grids. They also can cause aurora. Storms are rare during solar minimum, but as the sun’s activity ramps up every 11 years toward solar maximum – currently expected in late 2013 -- large storms occur several times per year. In the past, geomagnetic storms caused by CMEs of this strength and direction have usually been mild.

CAPE CANAVERAL, Fla. – In the clean room high bay at the Astrotech payload processing facility near NASA’s Kennedy Space Center in Florida, Applied Physics Laboratory technicians remove the protective shroud from around NASA's Radiation Belt Storm Probe B. Its twin, Radiation Belt Storm Probe A, in the background, has already been uncovered. The Radiation Belt Storm Probes, or RBSP, mission will help us understand the sun’s influence on Earth and near-Earth space by studying the Earth’s radiation belts on various scales of space and time. RBSP instruments will provide the measurements needed to characterize and quantify the plasma processes that produce very energetic ions and relativistic electrons. The mission is part of NASA’s broader Living With a Star Program that was conceived to explore fundamental processes that operate throughout the solar system, particularly those that generate hazardous space weather effects in the vicinity of Earth and phenomena that could impact solar system exploration. RBSP will begin its mission of exploration of Earth's Van Allen radiation belts and the extremes of space weather after launch. Launch aboard a United Launch Alliance Atlas V rocket is scheduled for August 23. For more information, visit http://www.nasa.gov/rbsp. Photo credit: NASA/Jim Grossmann

Three months before its scheduled arrival at Saturn, the Cassini spacecraft has observed two storms in the act of merging. With diameters close to 1,000 kilometers (621 miles), both storms, which appear as spots in the southern hemisphere, were seen moving west, relative to the rotation of Saturn's interior, for about a month before they merged on March 19 through 20, 2004. This set of eight images was taken between Feb. 22 and March 22, 2004. The top four frames span 26 days. They are portions of images from the narrow angle camera taken through a filter accepting light in the near-infrared region of the spectrum centered at 619 nanometers, and they show two storms approaching each other. Both storms are located at 36 degrees south latitude and sit in an anti-cyclonic shear zone, which means that the flow to the north is westward relative to the flow to the south. Consequently, the northern storm moves westward at a slightly greater rate than the southern one, 11 meters versus 6 meters per second (25 and 13 mph), respectively. The storms drift with these currents and engage in a counterclockwise dance before merging with each other. The bottom four frames are from images taken on March 19, 20, 21 and 22, in a region of the spectrum visible to the human eye; they illustrate the storms' evolution. Just after the merger, on March 20, the new feature is elongated in the north-south direction, with bright clouds on either end. Two days later, on March 22, the storm has settled into a more circular shape, and the bright clouds have spread around the circumference to form a halo. Whether the bright clouds are particles of a different composition or simply at a different altitude is uncertain. The new storm is a few tenths of a degree farther south than either of its progenitors. There, its westward velocity is weaker, and it is almost stationary relative to the planet's rotation. Although these particular storms move slowly west, storms at Saturn's equator move east at speeds up to 450 meters per second (1,000 mph), which is 10 times the speed of Earth's jet streams and three times greater than the equatorial winds on Jupiter. Saturn is the windiest planet in the solar system, which is another mystery of the ringed giant. The image scale ranges from 381 kilometers (237 miles) to 300 kilometers (186 miles) per pixel. All images have been processed to enhance visibility. http://photojournal.jpl.nasa.gov/catalog/PIA05386
