JWST Reveals Powerful Winds and Dense Atmosphere on Scorching Exoplanet TOI-561b
Astronomers using NASA’s James Webb Space Telescope have found compelling evidence that TOI-561b, an ultra-hot rocky exoplanet orbiting its star every 11 hours, still retains a dense atmosphere. Temperatures measured on both its day and night sides are far lower than expected for a bare rock, implying powerful winds and efficient heat transport. ...

Webb Telescope Discovers Hidden Atmosphere on Molten Super-Earth TOI-561 b Despite Extreme Heat
NASA’s Webb Telescope detects a hidden atmosphere on ultra-hot super-Earth TOI-561 b, revealing gases above its molten surface, challenging previous assumptions about small planets surviving intense stellar radiation.

NASA Missions Uncover a Diverse Galaxy of Super-Earths, Raising New Questions About Planetary Evolution
Super-Earths are among the most common planets in the galaxy, yet none exist in our solar system. Larger than Earth but smaller than Neptune, they range from ocean-covered worlds to scorched, atmosphere-less rocks. Some orbit within habitable zones, making them prime candidates for life. NASA’s Kepler and TESS missions, along with upcoming telesc...

Scientists Explore Role of Space Radiation in Powering Alien Microbial Life
A new study proposes that life may exist far from sunlight in a “radiolytic habitable zone” deep beneath the icy surfaces of Mars, Europa, and Enceladus. Cosmic rays, which can penetrate rock and ice, break water molecules apart to release hydrogen, oxygen, and energy-rich electrons. These can fuel microbes in subsurface water, much like bacter...

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 Near Earth May Be First Known Ocean World, Finds NASA's Webb Telescope
A planet relatively close to Earth could be the first ever detected with a potentially life-sustaining liquid ocean outside our Solar System, according to scientists using the James Webb space telescope.

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.
