By using PUNCH to image the Sun’s corona and the solar wind together, scientists hope to better understand the entire inner heliosphere — including the Sun, solar wind, and Earth — as a single connected system.\n\nPUNCH launched on March 11, 2025, from Vandenberg Space Force Base in California.\n\nLearn more: science.nasa.gov/mission/punch",

            "description": "In a teleconference with reporters on Tuesday, October 15, 2024, representatives from NASA, the National Oceanic and Atmospheric Agency (NOAA), and the Solar Cycle Prediction Panel announced the Sun has reached its solar maximum period.The solar cycle is the natural cycle of the Sun as it transitions between low and high activity. Roughly every 11 years, at the height of the solar cycle, the Sun’s magnetic poles flip — on Earth, that’d be like the North and South Poles swapping places every decade — and the Sun transitions from sluggish to active and stormy.During the most active part of the cycle, known as solar maximum, the Sun can unleash immense explosions of light, energy, and solar radiation — all of which create conditions known as space weather. Space weather can affect satellites and astronauts in space, as well as communications systems — such as radio and GPS — and power grids on Earth. When the Sun is most active, space weather events become more frequent. Solar activity, such as the storm in May 2024, has led to increased aurora visibility and impacts on satellites and infrastructure in recent months.Listen to the media telecon.Read NASA's article about the news. || ",

            "title": "Aerosol Optical Thickness Updating Forecast",
            "description": "The atmosphere is made up of gases like oxygen, nitrogen, and water vapor, but it also contains tiny particles called aerosols. Aerosols come from both natural and human sources and include things like sea salt, dust, soot, and sulfates. Aerosols often contribute to air pollution and poor visibility. Once they are in the atmosphere, they can travel long distances, affecting air quality far from their source. Aerosols also absorb or reflect energy (light), influencing temperatures in the atmosphere and on the ground. Satellites measure aerosols by how much light can pass through them. A thick layer of aerosols will block the ground from view, while a thin layer allows enough light through to see the ground. The measurement is called aerosol optical thickness.The GEOS model is built on satellite data and provides a forecast of aerosol optical thickness (among other things). This animation shows a daily updated 10-day forecast of aerosol optical thickness from GEOS. The date and timestamp are in the lower left corner. In general, brighter colors are thick aerosols, while dull darker colors are thin aerosols. Blue represents sea salt (sea salt extinction aerosol optical thickness, 550 nm). Winds blowing across the ocean kicks up ocean spray, which includes sea salt. In the animation, pale blue to white colors reflect stormy conditions. Individual large storms like tropical cyclones (hurricanes, typhoons) are visible as swirling circles of thick sea salt. Red represents dust (dust extinction aerosol optical thickness, 550 nm). The Saharan Desert of northern Africa is the largest source of dust, but dust can be seen across the globe. Saharan dust often interacts with tropical cyclones.Green represents the sum of aerosol optical thickness for organic carbon, black carbon, and sulfate. Organic and black carbon come from burning biomass or fossil fuels. Sources include fires, power plants, vehicles, and other combustion engines that run on fossil fuel. Sulfate particles come mostly from burning fossil fuels, but also from volcanoes. || gmao_aerosols_print.jpg (1024x576) [201.6 KB] || gmao_aerosols_searchweb.png (320x180) [108.3 KB] || gmao_aerosols.00001_thm.png (80x40) [7.0 KB] || gmao_aerosols.mp4 (1920x962) [16.2 MB] || gmao_aerosols.webm (1920x962) [1.5 MB] || latest-wdates (2239x1123) [0 Item(s)] || latest-nodates (2239x1123) [0 Item(s)] || gmao_aerosols.mp4.hwshow [191 bytes] || ",

            "description": "This gallery was created for Earth Science Week 2015 and beyond. It includes a quick start guide for educators and first-hand stories (blogs) for learners of all ages by NASA visualizers, scientists and educators. We hope that your understanding and use of NASA's visualizations will only increase as your appreciation grows for the beauty of the science they portray, and the communicative power they hold. Read all the blogs and find educational resources for all ages at: the Earth Science Week 2015 page.Four turboprop engines roar to life under the autumnal Alaskan sun, and we begin to taxi to the main runway of Eielson Air Force Base. After extensive pre-flight configurations, our science payload is primed for our eight-hour mission. Without delay, the engines’ roar becomes a howl as we hurtle down the nearly three-mile stretch of runway until that near-weightless moment we become airborne. Our mission into the clouds of the arctic is underway.Clouds are important drivers of Earth’s climate by regulating the amount of sunlight that is absorbed at the ground versus what is reflected back into space. You’ve probably experienced this firsthand when sitting outside on a hot and sunny summer day when a fluffy cumulus cloud crosses the sky between you and the sun. The respite that you feel from the heat of the sun’s rays means that that energy is no longer reaching you at the surface. At the lower latitudes where most of us live, these thick, stratiform and cumuliform clouds have a cooling effect because the white cloud reflects the sun’s energy back to space instead of being absorbed by the dark brown soil, green trees and plants, or the blue ocean waters. The story is much more complicated at the high latitudes where the frozen ice surface is also very bright white and reflective. Under these conditions, clouds can actually have a net warming effect because they reflect a similar or smaller amount of the incoming sunlight, but also trap more of the outgoing heat radiation and keep it close to the surface (like a blanket.)The exact balance between heating and cooling depends on the cloud properties - droplet number and size - and where the clouds are located in the atmosphere (high or low altitude as well as overlying dark water or bright ice.) Unraveling these effects is important for understanding how the Earth’s radiation balance and climate exist now and how they are likely to change in the future.Differentiating the impacts of low-level clouds versus Arctic sea ice on sunlight from space is hard, because to a passive satellite sensor orbiting many hundreds of kilometers above the Earth’s surface, both the ice and cloud look very similar. To best visualize this system, we must go to the Arctic with scientific research aircraft to measure the cloud properties just below, above, and within the clouds themselves. This was precisely the motivation behind the NASA Arctic Radiation – IceBridge Sea and Ice Experiment (ARISE), which was conducted in the Alaskan Arctic from September-October, 2014.ARISE carried out 14 science flights aboard the NASA Wallops Flight Facility C-130 Hercules aircraft, which was outfitted with a comprehensive suite of scientific instrumentation including a laser altimeter for measuring the sea ice surface properties, in situ cloud probes, and a sun photometer and two radiometers (SSFR, BBR) for measuring the surface, aerosol, and cloud radiative properties. An example 8-hour flight track is shown for the September 7th science flight in the Google Map below. The aircraft was based at Eielson Air Force Base near Fairbanks, AK, and began each flight by transiting approximately 2 hours north to the vicinity of the ice edge in the Beaufort Sea. On the 7th, the aircraft flew a series of parallel, horizontal legs to cover a single satellite grid box of the overflying NASA Clouds and the Earth's Radiant Energy System (CERES) satellite. These measurements help CERES scientists to understand how small-scale variability in ice and cloud extent and properties affect their satellite-based retrievals.              Google map showing the flight track of the NASA C-130 aircraft during a research flight conducted on 7 September 2014 north of the Alaskan coast.          Before wrapping up the research flight on the 7th and beginning our 2-hour transit back to Fairbanks, we descended into the low-level clouds to measure their microphysical properties with the in situ cloud probes. The video below shows what it’s like to measure an Arctic cloud from inside it! The left side of the video shows the real-time data time series from our research instruments that we are continuously monitoring in flight. The top-right imagery is from the forward-facing camera in the C-130 cockpit. The bottom-right imagery is from the downward-facing, nadir camera mounted on the bottom of the aircraft. || ",

This spectacle will mark the first of four consecutive total lunar eclipses, a series known as a tetrad. A lunar eclipse occurs when the moon dips behind Earth’s shadow. Most eclipses are partial, meaning only portions of the moon are hidden from the sun. But sometimes the moon, Earth, and sun perfectly align so that the entire moon is shielded from the sun’s rays. When this happens, wayward beams of sunlight filter through Earth’s atmosphere, coloring the moon a fiery red, resulting in a total eclipse. While a tetrad itself isn’t rare, NASA scientists say that its visibility across the entire United States is unique. Watch the video to learn more. || ",

The dust plume is shaped by the wind, forming waves near the surface immediately offshore. An even higher, thinner tan cloud veils the surface-level dust. Dust has infiltrated into different heights of the atmosphere. Differences in wind direction at various heights in the atmosphere create the “X” near the center of the dust plume.In certain atmospheric conditions, dust from the Sahara Desert is transported clear around the globe. In fact, many scientists use space-based multi-angle imaging to track the journey of dust.

            "description": "This visualization shows the dataset from STEREO-A processed to enhance the visibility of the coronal mass ejection (CME) in entry #3846. The data are combined from the SECCHI instrument, which includes an ultraviolet image of the Sun (EUVI), two coronographs (COR-1 & COR-2), and the wide-angle Heliospheric Imagers (HI-1 & HI-2).Because the enhancement process for the CME involves computing differences from a number of sequential HI-1 and HI-2 images, the Earth (left side) and Venus (middle) are masked and oversized icons are installed to mark their position. The dark shape on the left of the field of view is created by an occulting tab that was installed to (occasionally) hide the bright Earth in the view.The little cross markers label three other planets in the view of STEREO. Uranus is almost invisible in the scale of this imagery, but is visible in full-resolution datasets. || ",

            "description": "The sun regularly spews forth bursts of particles and magnetic fields known as a coronal mass ejection, or, CME. A CME starts small in solar terms—just a few hundred times the size of the Earth—but it grows and changes as it travels toward the edges of the solar system. Scientists have been observing these events with satellites for decades, but tracking the details of an ejection's growth from original seed to complex structure near Earth has been more challenging. In fact, scientists recently used three NASA spacecraft—STEREO-A, WIND and ACE—to create the first visual record of a CME's path from the sun to the Earth. The orbiting instruments captured the CME's birth on Dec. 12, 2008 at the sun's surface, its exponential growth and its ultimate engulfing of the Earth about three days later. These ejections are common but large solar events can alter our magnetic atmosphere to such a degree that communications signals from GPS or telecom satellites are temporarily degraded beyond recognition. This visualization allowed scientists to watch how features early in the CME ultimately create the form seen closer to Earth, with a bright leading edge and trailing evacuated cavity. || ",

Combined with solar observing satellites near the Earth, such as SDO and SOHO, this coverage will last for about eight years and the STEREO spacecraft move along in their orbits.This movie illustrates the orbital motions of the two STEREO spacecraft relative to the Earth (and noting the positions of the planets Mercury & Venus for reference). The camera occupies a position fixed relative to the Earth and Sun, so the distant starfield appears to spin around the observer. Because the frames are sampled at one per solar day, the Earth does not appear to rotate, but patient observation reveals that the tilt of the planet relative to the Sun, varies throughout the year, with the northern hemisphere tilted towards the Sun in northern hemisphere summer and away from the Sun in northern hemisphere winter. || ",

Combined with solar observing satellites near the Earth, such as SDO and SOHO, this coverage will last for about eight years and the STEREO spacecraft move along in their orbits.In this movie, we zoom in towards the Sun, fading from a visible light view to data from the 304 Ångstrom filters aboard SDO and both STEREO spacecraft. We swing the camera around to a view of the side of the Sun NOT visible from the Earth. With the STEREO and SDO data mapped to the sphere representing the Sun, we see the dark sliver of \"No Data\" which slowly shrinks as the STEREO spacecraft move into position 180 degrees apart on opposite sides of the Sun (and 90 degrees from Earth). STEREO data near the edge of the solar disk get stretched when projected onto a sphere and is responsible for the streaking on either side of the dark sliver. These data are sampled roughly six hours apart for each frame of the movie. Slight differenences in the six hour time step creates a slight 'jitter' of the dark sliver. || ",

            "description": "During April and May, 2010, the Eyjafjallajökull volcano on Iceland's southern coast erupted, creating an expansive ash cloud that disrupted air traffic throughout Europe and across the Atlantic. This animation shows the flow of this ash cloud for three days in early May on an hourly basis as sensed from a geostationary satellite. The ash cloud heights were determined using an approach developed by NOAA/NESDIS/STAR for the next generation of Geostationary Operational Environmental Satellite (GOES-R). Data from EUMETSAT's Spinning Enhanced Visible and Infrared Imager (SEVIRI) was used as a proxy for GOES-R Advanced Baseline Imager (ABI) data. This data is shown intersecting with the CALIPSO Parallel Attenuated Backscatter curtain on May 6th.

Maps and datasets collected by LRO's state-of-the-art instruments will form the foundation for all future lunar exploration plans, as well as be critical to scientists working to better understand the moon and its environment. In only the first year of the mission, LRO has gathered more digital information than any previous planetary mission in history. To celebrate one year in orbit, here are ten cool things already observed by LRO. Note that the stories here are just a small sample of what the LRO team has released and barely touch on the major scientific accomplishments of the mission.

            "description": "Solar Dynamics Observatory (SDO) will dramatically increase our ability to collect data about the Sun. This visualization compares the temporal and spatial resolution of SOHO/EIT with TRACE. SDO will enable TRACE-like image and temporal resolution over the entire solar disk. This movie opens with a full-disk view of the Sun in ultraviolet light (195 angstroms) from SOHO/EIT using the traditional TRACE 'gold' color table. We zoom in on the active region on the western limb where the TRACE instrument is pointing and fade-in an inset of the higher-resolution TRACE data. To emphasize the comparison, the TRACE inset is moved aside (with a solid white border) revealing the matching EIT data view (enclosed in the faint white border). At this point, we step through the time series of data frames. In this movie, much of the TRACE imagery is collected at time intervals between 3 and 40 seconds. On the other hand, a new SOHO/EIT image is taken about every 12 minutes (720 seconds). The SDO Atmospheric Imaging Assembly (AIA) will take full-disk solar images at four times the SOHO/EIT spatial resolution, a whopping 4096x4096, and at least 70 times the temporal resolution, 10 seconds or better per image. This creates a data rate over 1000x higher than SOHO/EIT. It is roughly equivalent to TRACE spatial and temporal resolution, but over the entire solar disk. || ",

            "description": "A series of dust clouds originating with distinct wind events over Asia two weeks ago, have made their way across the Pacific and spread a whitish haze across half of the U.S., sources say.Gene Feldman, a scientist at NASA's Goddard Space Flight Center in Greenbelt, MD said aircraft have been monitoring the particulates in the dust clouds.  Apparently, the dust clouds picked up industrial pollution from two of China's largest cities and are now blanketing the mid-Western United States with this matter.  Dr. Feldman said, \"At one time, the dust cloud was bigger than Japan.\"As early as 1998, scientists were claiming that industrial pollution from China was spreading to the United States where pollution in the U.S. was rising to two-thirds the federal health limits.  The current storm proves this theory to be true.  Pollution from Asia is reaching in the U.S. in alarming amounts.The particulates in the dust clouds that reduce visibility and cause respiratory problems have not been measured in such high volume since Mt. St. Helens erupted, and even then, the particulates did not reach the ground as they are in this case.The dust storms could even reach the Eastern U.S., but experts say they will probably dissipate as they move across the midwest. || ",
