Simulated View of Thermal Emissions from Europa
Scientists based this image on a model of data from NASA’s Galileo mission and data from an instrument on NASA’s Cassini mission that studied warm regions of Saturn’s moon Enceladus […]
Ideas On Abiotic Organic Synthesis Based On Oceanic Crust Findings
Recently, a Chinese research team reported the discovery of abiotic organic compounds in the oceanic crust of the Southwest Indian Ridge and proposed a molecular mechanism for organic condensation.
Hidden Ecosystems Discovered In Earth’s Seafloor Beneath Hydrothermal Vents
The idea of secret worlds beneath the Earth has long been the stuff of science fiction. But new research reveals it’s not as far-fetched as it might appear. Worms and […]
Signature of Vertical Mixing in Hydrogen-dominated Exoplanet Atmospheres
Vertical mixing is a crucial disequilibrium process in exoplanet atmospheres, significantly impacting chemical abundance and observed spectra. While current state-of-the-art observations have detected its signatures, the effect of vertical mixing […]
Animal Life Discovered Below The Seafloor at Hydrothermal Vents
The discovery of animal life below the seafloor at hydrothermal vents in the East Pacific Rise is reported in a Nature Communications paper. The research sheds new light on the […]
X-Raying Neutral Density Disturbances in the Mesosphere and Lower Thermosphere induced by the 2022 Hunga-Tonga Volcano Eruption-Explosion
We present X-ray observations of the upper atmospheric density disturbance caused by the explosive eruption of the Hunga Tonga-Hunga Ha’apai (HTHH) volcano on 15 January 2022.
Hubble’s Ultraviolet Observations Reveal Hydrogen and Oxygen at Europa
Ultraviolet observations made by NASA’s Hubble Space Telescope in 2012 illustrate two key elements in the thin atmosphere of Jupiter’s moon Europa: hydrogen and oxygen. A white circle indicates the […]
