Signs of Alien Life Detected on Nearby Exoplanet Using NASA’s James Webb Space Telescope
Astronomers have detected possible biosignature gases, including dimethyl sulfide (DMS), in the atmosphere of exoplanet K2-18b using NASA’s James Webb Space Telescope. Located in the habitable zone, this “Hycean” world may host a vast ocean and a hydrogen-rich atmosphere, raising intriguing possibilities about alien life. Further research is ...

Scientists Observe Rare Plastic Ice, A Hybrid Form of Ice and Water, Under Extreme Pressure and Heat
Researchers have observed plastic ice, a phase where water molecules rotate while staying in a solid structure. The discovery, made under extreme pressure and heat, could provide new insights into the composition of icy exoplanets and moons. The findings suggest plastic ice VII may have existed in Europa and Titan's interiors and could influence nu...

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...

Exoplanet Oceans Could Flow In Reverse - Creating Very Strange Climates, Scientists Say
With the explosion of exoplanet discoveries in recent years, we are learning more and more about what the universe can produce - inevitably sparking a Saganesque mix of science and sheer imagination, as researchers try to apply what they know about the Earth's workings to discern what's possible elsewhere.

Exoplanets May Be More Hospitable Than Previously Thought: Study
"Planets with potential oceans could have a climate that is much more similar to Earth's than previously expected."

Super-Earths may have oceans and continents
Super-Earths - common in our Milky Way galaxy - may have both oceans and exposed continents, suggesting these exoplanets have a stable climate like that of our Earth, scientists have found.
