  TRAPPIST-1b Could Have Carbon Dioxide-Rich Atmosphere, Study Reveals

  A new study published in Nature Astronomy proposes that TRAPPIST-1b, the innermost planet in the TRAPPIST-1 system, might have a carbon dioxide-rich atmosphere. This discovery comes from new data showing a reflective haze in the planet's upper atmosphere. Scientists are also investigating the possibility of volcanic activity based on the planet’s...

  NASA Satellite Image Reveals Unique Horseshoe-Shaped Deception Island in Antarctica

  NASA's Landsat 8 satellite captured an image of Deception Island, a horseshoe-shaped semi-submerged volcanic caldera located in the South Shetland Islands. Created by an eruption approximately 4,000 years ago, it remains vital for scientific research and as a safe harbour for ships navigating the harsh Southern Ocean. Deception Island is home to th...

  Jupiter’s Moon Io Shows No Magma Ocean as New Findings Explain Volcanic Eruptions

  NASA's latest findings indicate that Jupiter's volcanic moon Io does not have a global magma ocean beneath its surface, debunking previous theories. This conclusion comes from analysis of data from NASA's Juno spacecraft and archival observations from the Galileo mission. The study suggests that Io's interior is more solid than expected, with volca...

  Venus Never Had Oceans or Conditions to Support Life, New Study Finds

  Scientists from the University of Cambridge have concluded that Venus likely never had oceans or conditions to support life. Their study, published in Nature Astronomy, analysed atmospheric chemistry and volcanic activity. They found that volcanic gases lacked significant steam, indicating the planet's interior has always been dry. This research ha...

  Moon Rocks Brought From the Far Side Confirm Ancient Volcanic Activity

  Researchers analysing lunar samples from China’s Chang’e-6 mission have uncovered evidence of ancient volcanic activity on the Moon’s far side. The mission, which returned nearly two kilograms of lunar soil in June, landed in the South Pole-Aitken Basin, one of the Moon’s oldest craters. Studies published in Science and Nature revealed volc...

  What Studies On Soil Sample From Moon's Far Side Have Found

  Volcanic rock in the sample collected by Chang'e-6, the first mission that brought back soil from the far side of the Moon, is about 2.8 billion years old, suggesting the landing site was volcanically active at the time, according to two new studies.

  Scientists Confirm Volcanic Eruptions on Moon’s Far Side in New Study

  A recent study has confirmed the existence of volcanic eruptions on the Moon’s far side. By analysing lunar soil samples brought back by China’s Chang’e-6 mission, scientists discovered volcanic rock fragments dating to over 2.8 billion years ago. These findings reveal a long history of volcanic activity on the Moon’s far side, mirroring th...

  Africa’s Gradual Split Could Lead to the Formation of Earth’s Sixth Ocean

  Africa is experiencing significant tectonic activity, resulting in a gradual split that could lead to the formation of a new ocean in approximately 50 million years. This process is primarily observed in the East African Rift System, where geological movements are creating divisions between the Nubian and Somalian plates. Experts are examining the ...

  Mars Gravity Maps Shows Strange Hidden Structures Underneath the Surface

  Scientists have unveiled a new gravity map of Mars, revealing hidden structures beneath the surface and active processes affecting Olympus Mons. The map, presented at the Europlanet Science Congress 2024, challenges traditional geological models and shows dense structures under Mars' northern polar plains. Researchers suggest that a mantle plume mi...

  Chang’e 5 Probe Reveals Volcanic Activity on the Moon Occurred Much Earlier Than Previously Believed

  China's Chang'e 5 mission has brought new insight into the Moon's volcanic history, suggesting that the volcanic activity might have taken place much sooner than previously believed. Samples of lunar soil, returned to Earth in 2020, contain glass beads formed by volcanic eruptions just 120 million years ago. This is a significant discovery, as it c...

  Moon Had Surprisingly Recent Volcanic Activity, Samples Confirm

  Volcanoes were erupting on the Moon as recently as 120 million years ago, evidence collected by a Chinese spacecraft suggests. Until the last few years, scientists had thought volcanic activity ended on the Moon around 2 billion years ago.

  Study Reveals Ultra-Low Velocity Zones May Be More Common in Earth's Mantle Than Previously Thought

  A new study published in AGU Advances has unveiled intriguing findings about ultra-low velocity zones (ULVZs) in Earth's mantle, suggesting these mysterious features might be more widespread than previously thought.ULVZs, which are known to dramatically slow seismic waves by up to 50%, have long been associated with volcanic hotspots such as Hawaii...

  Worst Volcanic Activity In 50 Years In Iceland After Major Volcano Eruption

  A volcanic eruption has begun again on a peninsula adjacent to Iceland's capital Reykjavik, the sixth time lava has emerged in the area in the space of a year. The Lava burst to the surface at 9:26 p.m. local time on Thursday.
