When rain falls from Titan’s methane clouds into its hydrocarbon lakes, it can transport organic molecules like acrylonitrile that are attracted to both water and oil. Such amphiphile molecules are likely to collect in a thin film on the surface of Titan’s lakes. As large raindrops pelt the lakes, they could stir up this floating “pond scum” to form spherical droplets of methane coated in a bilayer of amphiphiles – structures called vesicles that resemble cell membranes on Earth.Although such vesicles have yet to be detected on Titan, a 2025 study by Christian Mayer and NASA scientist Conor Nixon lays out the process for their formation and evolution, and it proposes a mechanism for their discovery by a future mission to Titan. The paper also proposes that different mixtures of amphiphiles could stabilize vesicles and lead to the evolution of simple protocells on Titan. || ", "hits": 261 }, { "id": 5591, "url": "https://svs.gsfc.nasa.gov/5591/", "result_type": "Visualization", "release_date": "2025-12-29T14:00:00-05:00", "title": "ICESat-2 Land Ice Height Change (2020-2025)", "description": "NASA’s ICESat-2 satellite measures the elevation of Earth’s surfaces – and two data products from the mission map the height of Antarctic and Greenland ice sheets, as well as how those ice sheets change over time.

Over billions of years, the Red Planet has transformed from a potentially habitable world with lakes, rivers, and a thicker atmosphere into the cold, dry desert we see today. NASA’s MAVEN mission has been tracking this process in real time, catching Mars in the act of slowly sputtering its atmosphere into space.This phenomenon—called “atmospheric sputtering”—happens when high-energy particles from the Sun slam into Mars’s upper atmosphere, knocking atoms and molecules loose. Without a global magnetic field to protect it, Mars is especially vulnerable. MAVEN has shown that this atmospheric escape accelerates during solar storms, offering a powerful view of how the Sun shapes the evolution of planetary atmospheres.The data from MAVEN doesn’t just tell us about Mars—it helps us understand how atmospheres behave across the solar system and beyond. It’s a glimpse into what makes a planet stay habitable—or lose that potential entirely.For more information, visit https://science.nasa.gov/mission/maven/Credit: NASA's Goddard Space Flight Center Dan Gallagher: Lead ProducerPaul Morris: Producer / EditorDr. Shannon Curry: Scientist / IntervieweeWillow Reed: Public AffairsNancy Jones: Public AffairsGreg Shirah: Data VisualizerCindy Starr: Data VisualizerKel Elkins: Data VisualizerWalt Feimer: AnimatorMichael Lentz: AnimatorChris Smith: AnimatorJonathan North: AnimatorBrian Monroe: AnimatorLisa Poje: Graphic DesignerAdriana Manrique Gutierrez: Graphic DesignerKim Dongjae: Graphic DesignerErnie Wright: SupportAaron E.

Such molecules freeze at very low temperatures and can still exist as a liquid in Titan’s frigid minus 290°F weather. Cassini has surveyed Titan since it arrived at the Saturn system in 2004. Any wave, even millimeters high, would appear as a bright spot in its radar images. So why isn’t the surf up on these alien lakes? Researchers have put forth a new theory that may explain their calm surface.

This time series of data shows images acquired by three different Landsat satellites operated by NASA and the U.S. Geological Survey.The green fields that dot the desert draw on water that in part was trapped during the last Ice Age. In addition to rainwater that fell over several hundred thousand years, this fossil water filled aquifers that are now buried deep under the desert's shifting sands.Saudi Arabia reaches these underground rivers and lakes by drilling through the desert floor, directly irrigating the fields with a circular sprinkler system. This technique is called center-pivot irrigation.Because rainfall in this area is now only a few centimeters (about one inch) each year, water here is a non-renewable resource. Although no one knows how much water is beneath the desert, hydrologists estimate it will only be economical to pump water for about 50 years.In this series of four Landsat images, the agricultural fields are about one kilometer (.62 miles) across. The images were created using reflected light from the short wave-infrared, near-infrared, and green portions of the electromagnetic spectrum (bands 7, 4, and 2 from Landsat 4 and 5 TM and Landsat 7 ETM+ sensors). Using this combination of wavelengths, healthy vegetation appears bright green while dry vegetation appears orange. Barren soil is a dark pink, and urban areas, like the town of Tubarjal at the top of each image, have a purple hue.Landsat 4 launched in 1982 and provided scientific data for 11 years until 1993. NASA launched Landsat 5 in 1984 and it ran a record-breaking 28 years, sending back what was likely its last data in 2011. Landsat 7 is still up and running; it was launched in 1999. The data from these and other Landsat satellites has been instrumental in increasing our understanding of forest health, storm damage, agricultural trends, urban growth, and many other ongoing changes to our land.NASA and the U.S. Department of the Interior through the U.S. Geological Survey (USGS) jointly manage Landsat, and the USGS preserves a 40-year archive of Landsat images that is freely available data over the Internet.

The Tropical Rainfall Measurement Mission (TRMM) Multisensor Precipitation Analysis (TMPA) provides three-hourly estimates of rainfall rate across much of the globe. Here we see the seasonal cycle of monthly precipitation derived from TMPA for Africa, including the Nile Basin. The annual migration of the Intertropical Convergence Zone (ITCZ) from the Nile Equatorial Lakes region around Lake Victoria, source of the White Nile, northward into Sudan and the highlands of Ethiopia, headwaters of the Blue Nile, and back is evident in the seasonal cycle in precipitation. This precipitation cycle drives flow through the Nile River system. The Nile basin, however, is intensely evaporative, and the majority of the water that falls as rain leaves the basin as evaporation rather than river flow—either from the humid headwaters regions or from large reservoirs and irrigation developments in Egypt and Sudan. The Atmosphere Land Exchange Inverse (ALEXI) evapotranspiration product, developed by USDA scientists, uses satellite data to map daily evapotranspiration across the entire Nile basin, providing unprecedented information on water consumption. The balance of rainfall and evapotranspiration can be seen in seasonal patterns of soil moisture, as simulated by the NASA Nile Land Data Assimilation System (LDAS), which merges satellite information with a physically-based land surface model to simulate variability in soil moisture—a critical variable for rainfed agriculture and natural ecosystems. Finally, the twin satellites of the Gravity Recovery and Climate Experiment (GRACE) can be used to monitor variability in total water storage, including surface water, soil moisture, and groundwater. The annual cycle in GRACE estimates of water storage anomalies clearly shows the seasonal movement of water storage due to precipitation patterns and the movement of surface waters from headwaters regions into the wetlands of South Sudan and the reservoirs of the lower Nile basin.The Nile is the longest river in the world and its basin is shared by 11 countries. Reliable, spatially distributed estimates of hydrologic storage and fluxes can provide critical information for water managers contending with multiple resource demands, a variable and changing climate, and the risk of damaging floods and droughts. NASA observations and modeling systems offer unique capabilities to meet these information needs. || ", "hits": 177 }, { "id": 11176, "url": "https://svs.gsfc.nasa.gov/11176/", "result_type": "Produced Video", "release_date": "2013-01-31T00:00:00-05:00", "title": "Europa's Chaos Terrains", "description": "Hard layers of ice make up the surface of Jupiter's frozen moon Europa. Glacial cracks and ridges scar its frigid white plains, carving paths across an icy shell that conceals a deep ocean of liquid water. Closer inspection of the moon's fractured topography reveals highly disrupted areas, called chaos terrains, where blocks of ice appear to have broken off, drifted and refrozen to the surface. Searching for an explanation of how these features formed, researchers studying images of Europa taken by NASA's Galileo spacecraft have come up with an answer. As plumes of warm ocean water rise to the subsurface, massive lakes develop inside the moon's crust—some larger than North America's Great Lakes combined. Over time, the ice directly above these lakes collapses, splintering into floating geometric fragments that rotate, raft and resettle into all kinds of chaotic configurations.

Snow plays a key role in the Earth's energy balance, reflecting most of the sunlight that reaches its surface back to space, preventing warming of the ground beneath. Snow also absorbs energy from the atmosphere during spring melt, keeping temperatures moderate. Satellite measurements of snow extent began in the 1960s, and this lengthy record shows a 10 percent decline in annual snow cover since 1966, mainly due to earlier spring melting. Darker, snow-free ground absorbs more solar radiation and emits more warmth to the atmosphere. The snow cover loss is also a concern for those who depend on snowmelt for drinking water. Watch the visualizations below, based on data from NASA's MODIS instrument, to see the dramatic variation in a year of Earth's snow cover. In the Northern Hemisphere, the first flakes fall in mid-September over Siberia and Alaska. By the end of February, snow cover starts its retreat northward.

The ice front, where the glacier calves into the sea, receded more than 40 km between 1850 and 2006. Between 1850 and 1964 the ice front retreated at a steady rate of about 0.3 km/yr, after which it occupied approximately the same location until 2001, when the ice front began to recede again, but far more rapidly at about 3 km/yr. As more ice moves from glaciers on land into the ocean, it causes a rise in sea level. Jakobshavn Isbrae is Greenland's largest outlet glacier, draining 6.5 percent of Greenland's ice sheet area. The ice stream's speed-up and near-doubling of the ice flow from land into the ocean has increased the rate of sea level rise by about .06 millimeters (about .002 inches) per year, or roughly 4 percent of the 20th century rate of sea level increase. This may be due in part to the numerous melt lakes visible here near the top of the image. These are believed to lubricate the layer between the ice sheet and bedrock, causing the ice to flow faster toward the sea.
