These two radar images show the majestic Yellowstone National Park, Wyoming, the oldest national park in the United States and home to the world's most spectacular geysers and hot springs. The region supports large populations of grizzly bears, elk and bison. In 1988, the park was burned by one of the most widespread fires to occur in the northern Rocky Mountains in the last 50 years. Surveys indicated that 793,880 acres of land burned. Of that, 41 percent was burned forest, with tree canopies totally consumed by the fire; 35 percent was a combination of unburned, scorched and blackened trees; 13 percent was surface burn under an unburned canopy; 6 percent was non-forest burn; and 5 percent was undifferentiated burn. Six years later, the burned areas are still clearly visible in these false-color radar images obtained by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar on board the space shuttle Endeavour. The image at the left was obtained using the L-band radar channel, horizontally received and vertically transmitted, on the shuttle's 39th orbit on October 2, 1994. The area shown is 45 kilometers by 71 kilometers (28 miles by 44 miles) in size and centered at 44.6 degrees north latitude, 110.7 degrees west longitude. North is toward the top of the image (to the right). Most trees in this area are lodge pole pines at different stages of fire succession. Yellowstone Lake appears as a large dark feature at the bottom of the scene. At right is a map of the forest crown, showing its biomass, or amount of vegetation, which includes foliage and branches. The map was created by inverting SIR-C data and using in situ estimates of crown biomass gathered by the Yellowstone National Biological Survey. The map is displayed on a color scale from blue (rivers and lakes with no biomass) to brown (non-forest areas with crown biomass of less than 4 tons per hectare) to light brown (areas of canopy burn with biomass of between 4 and 12 tons per hectare). Yellow indicates areas of canopy burn and mixed burn with a biomass of between 12 to 20 tons per hectare; light green is mixed burn and on-burn forest with a biomass of 20 to 35 tons per hectare; and green is non-burned forest with a biomass of greater than 35 tons per hectare. Forest recovery from the fire seems to depend on fire intensity and soil conditions. In areas of severe canopy burn and poor soil conditions, crown biomass was still low in 1994 (indicated by the brown areas at the center left), whereas in areas of mixed burn with nutrient-rich soils, seen west of Yellowstone Lake, crown biomass has increased significantly in six years (indicated by the yellow and light green areas). Imaging fire-affected regions with spaceborne radar illustrates SIR-C/X-SAR's keen abilities to monitor regrowth after a fire. Knowing the amount of carbon accumulated in the atmosphere by regenerating forest in the 20 to 50 years following a fire disturbance is also a significant factor in understanding the global carbon cycle. Measuring crown biomass is necessary to evaluate the effects of past and future fires in specific regions. http://photojournal.jpl.nasa.gov/catalog/PIA01741

The blue dots in this field of galaxies, known as the COSMOS field, show galaxies that contain supermassive black holes emitting high-energy X-rays. The black holes were detected by NASA's Nuclear Spectroscopic Array, or NuSTAR, which spotted 32 such black holes in this field and has observed hundreds across the whole sky so far. The other colored dots are galaxies that host black holes emitting lower-energy X-rays, and were spotted by NASA's Chandra X-ray Observatory. Chandra data show X-rays with energies between 0.5 to 7 kiloelectron volts, while NuSTAR data show X-rays between 8 to 24 kiloelectron volts. http://photojournal.jpl.nasa.gov/catalog/PIA20865

The fire, burning in Wyoming 18 miles (29 kilometers) west of Big Piney, was discovered on June 24. [Editor?s update --- By the morning of June 28, the fire had burned 25,000 acres (101 square kilometers). By July 6, the area burned had more than doubled to 57,324 acres (232 square kilometers), and the fire was 25 percent contained].

On Aug. 21, 2017, a total solar eclipse swept across the United States -- the first such eclipse in the contiguous 48 states since 1979, and the first cross-country eclipse since 1918. A partial eclipse was visible in all 50 states, and initial estimates suggest that upwards of 20 million people observed the Moon completely obscuring the Sun in the 70-mile-wide (113-kilometer-wide) path of totality. While viewing a total solar eclipse from the ground is an amazing experience, satellites orbiting Earth see the eclipse from a unique perspective. As the Moon's shadow passed through the United States, the Multi-angle Imaging SpectroRadiometer (MISR) instrument aboard NASA's Terra satellite was capturing images of eastern Wyoming and western Nebraska from its altitude of 438 miles (705 kilometers) above the surface. MISR gathers images on a strip about 249 miles (400 kilometers) wide directly below the path of the satellite. Incredibly, given that the shadow of the Moon took only 90 minutes to cross the entire United States, and Terra itself moves at a brisk 16,700 miles per hour from north to south, MISR happened to be in exactly the right place at the right time to capture totality. From the ground, the moment of totality appears suddenly, sweeping over the sky in just a few seconds. "I was unprepared for just how dark it actually was," says Mika Tosca, a researcher who works with MISR data and who observed the eclipse in Nebraska. "The streetlights even turned on. Everything fell silent, and I swear the temperature dropped." From the vantage point of space, however, it’s possible to see the entire shadow of the Moon, with the completely dark, circular umbra and the more diffuse penumbra. MISR contains nine cameras oriented at different angles, viewing forward, downward, and backward along the flight path, resulting in an approximate seven-minute interval for all nine cameras to image a single location on Earth's surface. This animation combines these nine images into a movie showing the motion of the Moon's shadow during this seven-minute period. In the first image, captured by the camera pointing farthest ahead of the satellite, totality has not quite begun in the area seen by MISR. From the second camera onward, totality sweeps across the image area from west to east, beginning just west of the town of Jay Em, Wyoming, and proceeding about halfway across the MISR swath to the town of Alliance, Nebraska. The motion of the lunar shadow in different pairs of images leads to estimates of the local ground speed ranging between 1,480 and 1,820 miles per hour (2,382 and 2,929 kilometers per hour). The spread in values is a measure of the uncertainty of the estimate. At this location, the predicted speed of the eclipse calculated from lunar orbital motion is about 1,658 miles per hour (2,668 kilometers per hour), which falls in the middle of the range estimated from the MISR images. Tosca's observation that the temperature dropped during the eclipse is a well-known phenomenon. The GLOBE Observer, a phone application dedicated to citizen science and sponsored by NASA, encouraged eclipse-goers to record the local air temperature at regular intervals. Data collected by nearby observers in the path of totality show that, on average, temperatures dropped by 9.3 degrees Fahrenheit (5.2 degrees Celsius) during the eclipse. This compares to an average of 5.4 degrees Fahrenheit drop measured at several Nebraska Mesonet weather stations within the path of totality. The decrease in the amount of sunlight reaching Earth affected more than temperatures. Areas that get a large portion of their power from solar energy were naturally concerned about shortages during the eclipse -- the state of California, though not in the path of totality, estimated that 6,000 megawatts of solar power would be lost during the eclipse.

ISS024-E-015121 (20 Sept. 2010) --- Twitchell Canyon Fire in central Utah is featured in this image photographed by an Expedition 24 crew member on the International Space Station (ISS). The Twitchell Canyon Fire near central Utah?s Fishlake National Forest is reported to have an area of approximately 13,383 hectares (approximately 134 square kilometers, or 33,071 acres). This detailed image shows smoke plumes generated by several fire spots close to the southwestern edge of the burned area. The fire was started by a lightning strike on July 20, 2010. Whereas many of the space station images of Earth are looking straight down (nadir), this photograph was exposed at an angle. The space station was located over a point approximately 509 kilometers (316 miles) to the northeast, near the Colorado/Wyoming border, at the time the image was taken on Sept. 20. Southwesterly winds were continuing to extend smoke plumes from the fire to the northeast. While the Twitchell Canyon region is sparsely populated, Interstate Highway 15 is visible at upper left.

Astronomers using NASA's Hubble Space Telescope have found compelling evidence of a planet forming 7.5 billion miles away from its star, a finding that may challenge current theories about planet formation. Of the almost 900 planets outside our solar system that have been confirmed to date, this is the first to be found at such a great distance from its star. The suspected planet is orbiting the diminutive red dwarf TW Hydrae, a popular astronomy target located 176 light-years away from Earth in the constellation Hydra the Sea Serpent.

On April 29, 2015 the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra satellite captured a true-color image of a typical spring scene in the western United State: snow-crowned Rocky Mountains rising above the faintly greening plains. The Rocky Mountains stretch from British Columbia, Canada to the Rio Grande in New Mexico, a span of roughly 3,000 miles, and contains many of the highest peaks in the continental United States. The tallest, Mount Elbert, rises 14,400 ft. (4,401 m) above sea level, and is located in the San Isabel National Forest, near Leadville, Colorado. This image covers seven Rocky Mountain states. From north to south they are: Montana and Idaho, Wyoming; Utah (with the Great Salt Lake visible) and Colorado; Arizona and New Mexico. To the east, the Great Plain states captured are, from north to south: North Dakota, South Dakota, Nebraska, Kansas, Oklahoma and northwestern Texas.

Composed of 18 images, this natural-color mosaic shows a boulder field on "Mount Washburn" (named after a mountain in Wyoming) in Mars' Jezero Crater. The Perseverance science team nicknamed the light-toned boulder with dark speckles near the center of the mosaic "Atoko Point" (after a feature in the eastern Grand Canyon). The images were acquired by NASA's Perseverance Mars rover on May 27, 2024, the 1,162nd Martian day, or sol, of the mission. Analysis by the rover's SuperCam and Mastcam-Z instruments indicate Atoko Point is composed of the mineral pyroxene, similar to some boulders the rover has encountered elsewhere in Jezero Crater. In terms of the size, shape, and arrangement of its mineral grains and crystals – and potentially its chemical composition – Atoko Point is different from any of the rocks the rover has encountered before. Some Perseverance scientists speculate the minerals that make up Atoko Point were produced in a subsurface body of magma that is possibly exposed now on the crater rim. Others on the team wonder if the boulder, which stands about 18 inches (45 centimeters) wide and 14 inches (35 centimeters) tall, had been created far beyond the walls of Jezero and transported there by swift Martian waters eons ago. Arizona State University leads the operations of the Mastcam-Z instrument, working in collaboration with Malin Space Science Systems in San Diego, on the design, fabrication, testing, and operation of the cameras, and in collaboration with the Niels Bohr Institute of the University of Copenhagen on the design, fabrication, and testing of the calibration targets. A key objective for Perseverance's mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet's geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust). Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis. The Mars 2020 Perseverance mission is part of NASA's Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet. https://photojournal.jpl.nasa.gov/catalog/PIA26333

Bow shocks thought to mark the paths of massive, speeding stars are highlighted in these images from NASA's Spitzer Space Telescope and Wide-field Infrared Survey Explorer, or WISE. Cosmic bow shocks occur when massive stars zip through space, pushing material ahead of them in the same way that water piles up in front of a race boat. The stars also produce high-speed winds that smack into this compressed material. The end result is pile-up of heated material that glows in infrared light. In these images, infrared light has been assigned the colored red. Green shows wispy dust in the region and blue shows stars. The two images at left are from Spitzer, and the one on the right is from WISE. The speeding stars thought to be creating the bow shocks can be seen at the center of each arc-shaped feature. The image at right actually consists of two bow shocks and two speeding stars. All the speeding stars are massive, ranging from about 8 to 30 times the mass of our sun. http://photojournal.jpl.nasa.gov/catalog/PIA20062
