A new study by NASA and international scientists detects temperature changes in Venus' upper atmosphere, contrary to the planet's harsh surface conditions. The findings suggest that atmospheric circulation patterns may be more complex than previously thought, with potential implications for understanding Earth's own atmospheric evolution.
Scientists discovered a mysterious high-altitude sulphur dioxide layer on Venus that can help explain its formation. The new findings also suggest that injecting large quantities of sulphur dioxide into Earth's atmosphere to mitigate climate change may not be as effective as thought.
Scientists studying the Venus Express mission have found that Venus likely had oceans billions of years ago, but they were likely atmospheric and short-lived. The loss of water into space has left the planet's surface dry today.
Scientists from NASA and the European Space Agency found evidence of relatively young lava flows on Venus, suggesting the planet remains capable of volcanic eruptions. These findings indicate that volcanic activity on Venus is likely gradual rather than cataclysmic.
CU-Boulder is leading a $3.3 million concept study for a lander mission to Venus, aiming to study the planet's surface, climate, and atmosphere. The mission will compare Venus with other terrestrial planets and help understand Earth's fate.
Researchers investigated coral skeleton formation and found systematic compositional variations, complicating paleoenvironmental change proxies. Meanwhile, a study on Venus' vortices revealed similarities with terrestrial hurricanes, potentially aiding atmospheric superrotation understanding.
Scientists discover hydrogen gas being stripped from Venus' day-side, indicating water is being broken up in the atmosphere. The loss of hydrogen and oxygen suggests that water on Venus was once abundant but has since been depleted.
Scientists study Venus' atmosphere using instruments on board ESA's Venus Express, discovering high-contrast zones created by a mysterious chemical that absorbs ultraviolet light. Clouds are found at similar heights across dark and bright regions, with temperature variations influencing atmospheric dynamics.
A new study finds that Earth's plate tectonics could become unstable if the surface temperature rises by 100 degrees Fahrenheit or more for a few million years. This would cause the crust to become locked in place, leading to volcanic activity and a lack of tectonic plates moving.
The 'eye of a hurricane' on Venus is an enormous 2000 km-wide vortex with a central core that appears bright in thermal infrared images, indicating high atmospheric gas movement. Scientists are still unsure what creates the complex and dynamic nature of this feature.
The Mars Express and Venus Express spacecraft reveal that the two planets' atmospheres are stripped away into space due to solar wind interactions. The similarity in magnetic field structure between the two planets suggests a shared ionosphere density at high altitudes.
Researchers have found that electrons lose energy to carbon monoxide faster than to carbon dioxide at higher atmospheric levels on Mars and Venus. This discovery contributes to modeling techniques used for Earth's atmosphere, providing opportunities for validation and testing.
Researchers investigate anorthosites as a forgotten source of planetary magnetic anomalies, finding strong signatures of the Earth's magnetic field direction in ancient rocks. Another study proposes that gas hydrates in shallow marine sediments are the dominant source of methane in ice core records. A third study explores the feasibili...
University of Pennsylvania researchers have uncovered the key step in how herpes simplex virus, HSV-1, invades healthy cells using cooperating proteins on its outer coat. The study used biomolecular complementation with a fluorescent protein called Venus to demonstrate the effectiveness of monitoring protein interactions.
Researchers from the University of the Basque Country have published two articles in Nature on their findings about the atmosphere, climate and weather patterns of Venus. The studies revealed the presence of a double vortex at the South Pole, which is similar to those found on Earth's polar regions.
Researchers will make measurements of thick clouds and surface of Venus, comparing atmosphere with past data, using MASCS instrument. The mission also tests instrument performance before Mercury arrival and explores mineral composition, gas distribution, and water-ice at Mercury's poles.
The Planetary Society and ESA celebrate the imagined rugged beauty of Venus with the winning entries in the 'Postcards from Venus' art contest. The Grand Prize winner, Tatianna Cwick, age 17, has won a trip to the European Space Operations Centre. Other winners include Yoo-Hong Sun, age 9, and Alejandra Gonzalez Quintana, Spain.
The European Space Agency's Venus Express spacecraft is on its journey to Venus, where it will study the planet's extremely hot atmosphere, high pressure, and mysterious 'super-rotation'. The spacecraft will deploy instruments to probe the surface and atmosphere, with a planned mission duration of at least two Venusian days.
The Venus mission aims to study the planet's surface and atmosphere, with a focus on volcanoes and potential biological activity. The spacecraft will use advanced instruments to detect 'hotspots' in the clouds and make a positive detection of volcanoes.
Scientists measured a 0.1% reduction in sunlight reaching Earth during a June 8 Venus transit using NASA's SORCE satellite data. This event is comparable to the estimated 50-year decrease in sunlight that occurred during the Little Ice Age in the 17th century.
During next week's transit, NCAR scientist Brown will examine regions of the solar spectrum absorbed by Venus's atmosphere between 65 and 85 kilometers altitude. He will also construct wind patterns based on gases' Doppler shifts to reveal atmospheric composition and temperature.
Researchers at Washington University in St. Louis have found that heavy metal snow on Venus is actually made of lead sulfide, contradicting previous hypotheses. This discovery could allow for the dating of Venus using lead isotopes, providing a new frontier for space exploration.
The DARE concept uses balloons with a StratoSail device to control their path in strong atmospheric winds, enabling pole-to-pole exploration of Venus and Titan's atmospheres and targeted observations of Mars and Jupiter's Great Red Spot.
Researchers propose that the continents emerged suddenly over 200 million years ago, coinciding with the formation of supercontinent Rodinia. This theory suggests that changes in plate tectonics may have triggered evolutionary activity and influenced life's evolution.
Researchers at Washington University in St. Louis found evidence that hot and dry Venus could have had water in its past due to the chemical stability of tremolite at extreme temperatures. This discovery could help scientists determine if they should investigate hydrous minerals on Venus.
A search for lightning on Venus in 1998 and 1999 using the Cassini spacecraft failed to detect high-frequency radio waves commonly associated with lightning. Donald Gurnett, a space physicist at the University of Iowa, suggests that if lightning exists on Venus, it may be extremely rare or very different from terrestrial lightning.
Computer models of Venus' changing climate system may provide insights into Earth's dynamic past and potential future. The models suggest that volcanic activity could have increased greenhouse gases in the atmosphere, leading to a cooling effect on the planet.
A new model of Venus suggests that crustal plateaus and volcanic rises were formed by a mechanism similar to hot spot plumes, a process still active on Earth. The thickening of the Venusian lithosphere approximately one billion years ago largely shut down the creation of crustal plateaus.
