A team of geoscientists from Rice University and partners have discovered a sharp, volatile-rich cap just 3.8 kilometers beneath Yellowstone's surface. This cap helps trap pressure and heat below it, suggesting the Yellowstone magma reservoir is actively releasing gas while remaining in a stable state.
Researchers found that prolonged droughts have led to Steamboat Geyser's dry spells by clogging pathways for trees to respire and grow. The team matched tree growth periods to regional climate records, revealing a connection between environmental conditions and reduced water supply.
The study of Doublet Pool reveals that the interval between episodes of thumping reflects the amount of energy heating the pool, while also indicating heat loss through the surface. The researchers found that wind speed over the pools was correlated with silence intervals, suggesting that blowing wind removes heat energy from the water.
A new study suggests that an orbiting space probe could provide definitive answers about the presence of life on Enceladus' ocean. The team mapped out how a hypothetical mission could gather data from the moon's plumes, which are thought to contain organic molecules and methane.
Researchers evaluated the history of hydrothermal explosions at Yellowstone Lake, discovering at least 16 deposits in sediment cores. The Mary Bay and Elliott's Craters were found to have larger extent of deposits than previously thought, with the lake level likely lower during the explosions.
A new study using subsurface imaging sheds light on the geological connection between Yellowstone's iconic hydrothermal features and deeper heat sources. The research team detected hydrothermal alteration and found a remarkable similarity in deep structure beneath areas such as Norris Geyser Basin and Lower Geyser Basin.
Scientists at Anglia Ruskin University have created a new way to experience Yellowstone's geysers through classical music. By sonifying the physical characteristics of the geothermal landscape, they've turned vibrations into melodies, harmonies, and rhythms. The result is an evolving musical representation of the earth, water, and steam.
A new study by geoscientists finds that the reactivation of Steamboat Geyser does not foretell any upcoming volcanic eruptions in Yellowstone National Park. The researchers discovered a relationship between the column height of the geyser and the depth of its reservoir, with deeper reservoirs resulting in higher eruption jets.
Astrophysicists use 3D simulations to explain how luminous blue variables launch material into space through intense light and turbulent motion. The study sheds light on the violent mood swings of rare, massive stars that can shed billions of metric tons of material annually.
A University of Cincinnati geology student, Andrew Gangidine, is developing a marker for ancient bacterial life on Mars to aid NASA's search. He's studying microbial life in silica hot springs at Yellowstone National Park to create a useful indicator of life on the red planet.
Researchers used dense seismograph network to map near-surface geology around Old Faithful, discovering a reservoir of heated water that fuels the geyser. The study also reveals how ground shaking behaves between eruptions and finds an underground feature affecting seismic waves in a specific area.
Scientists have deployed hundreds of seismometers around the Old Faithful Geyser in Yellowstone National Park to gain a clearer picture of how it erupts. The seismic data offer insights into the active hydrothermal system below the geyser, which could help monitor less predictable geysers.
A new class of galaxies called 'red geysers' has been discovered, hosting low-energy supermassive black holes that drive intense interstellar winds. These winds suppress star formation by heating up the ambient gas in galaxies and preventing it from cooling and condensing into stars.
A new phenomenon dubbed 'red geysers' has been identified in galaxies, which host low-energy supermassive black holes driving intense interstellar winds. These winds prevent gas from cooling and condensing into stars, maintaining quiescence in galaxies.
Scientists have pinpointed a mechanism for cyclical tidal stresses to drive and sustain Enceladus's long-lived eruptions. The Cassini spacecraft has observed geysers erupting continuously along the south pole for decades.
Researchers have found that the flux of organic matter to the seafloor was reduced for a shorter time than previously thought, with evidence suggesting that some food must have reached the seabed despite mass extinctions. The study used foraminiferal isotopes from a deep-sea core in the South Atlantic to investigate this paradox.
A new study by a team of Cassini mission scientists led by the University of Colorado Boulder has found evidence of hydrothermal activity on Enceladus, a Saturn moon with remarkable geologic activity. The tiny grains of rock detected near Saturn imply that seawater infiltrates and reacts with a rocky crust, emerging as a heated, minera...
A recent study by UC Berkeley professor Michael Manga found that geysers erupt periodically due to underground loops and side-chambers that trap steam bubbles. The study suggests that these underground features heat the water column above, eventually leading to sudden boiling and pressure release.
Recent studies published in Lithosphere explore the tectonic history of ancient mountain chains, including the Central Iberian Massif, Arctic Alaska, and the Wet Mountains of Colorado. These findings shed light on the deformation mechanisms and crustal-scale magmatism across these regions.
Research suggests that freshwater ecosystems were more resilient than oceans during the asteroid impact due to annual freeze-thaw cycles, groundwater seeps, and dormant stages of many organisms. This study also explores the bubbling of methane from thermokarst lakes, an important factor in the carbon cycle and global climate change.
Researchers propose a new model for the eruption of Yellowstone Park's Old Faithful geyser, based on three stages of convective boiling in the conduit. The model reproduces the geyser's bimodal eruption pattern, with long and short eruption intervals followed by similar durations.
The article discusses various geological topics, including the flatness of Earth, chemical weathering, and the distribution of radiogenic lead in zircons. The findings show that mountains do not play a significant role in 'carbon drawdown' effect and challenge previous studies.
A recent study suggests that Saturn's moon Enceladus' water vapor jets originate from the surface and not an underground ocean. The research, conducted by the University of Colorado at Boulder, found that the sodium content in the water vapor was too low to support the geyser hypothesis.
Scientists found that vents on Enceladus channel water vapor from a warm, probably liquid source to the surface at supersonic speeds. This supports a theory that tidal heating causes geysers and provides implications for life in the solar system.
A new study suggests that frictional heating is the most likely explanation for the plumes and features observed on Enceladus. The process occurs when tidal forces cause fault lines in the moon's icy shell to rub back and forth, producing enough heat to transform ice into water vapor and ice crystals.
Researchers propose a new model explaining the giant plume on Enceladus by dissolving gases in clathrate ice under the water ice cap. This environment allows for a Frigid Faithful plume, which produces nitrogen, methane, and carbon dioxide gases.
Researchers propose that Enceladus' reorientation could be caused by a low-density blob beneath its surface, leading to a hot spot at the pole and explaining the moon's striking surface features. The study suggests testable predictions for future observations of Enceladus.
Scientists have found evidence of geysers on Saturn's icy moon Enceladus that suggest near-surface liquid water reservoirs are erupting to form the geysers. The Cassini images reveal a change in the moon's shape and geologic activity over billions of years, indicating a possible source of heat for the geysers.
Researchers found microorganisms living in highly acidic conditions with high metal and silicate concentrations at Yellowstone's Norris Geyser Basin. These discoveries could provide clues about ancient life on Earth and aid in the search for life on Mars.
Scientists found prolonged changes in hydrothermal activity after a magnitude-7.9 Denali fault earthquake in Alaska triggered more than 1,000 small earthquakes in Yellowstone within a week. Some geysers erupted more frequently while others less often due to changes in water pressure and underground conduits.
