The Pacific and Atlantic Oceans meet off South America and do mix, despite appearances of a visible line due to differences in temperature, salinity, and sediment. Factors like climate change and pollution influence the rate of mixing, and misleading photos have circulated online, but the waters eventually blend together.

A recent study suggests that Uranus and Neptune may have vast oceans up to 5,000 miles deep beneath their atmospheres, potentially reshaping our understanding of these ice giants and their capacity to harbor life. Led by Professor Burkhard Militzer, the research used advanced computer simulations to reveal a layered structure within these planets, which could explain their unique magnetic fields. This discovery has significant implications for the search for extraterrestrial life, as similar gas giants are common in the Milky Way. Future missions to these planets could confirm these findings.

NASA is planning a mission to explore the possibility of hidden liquid oceans beneath the moons of Uranus, which could provide insights into the potential for life beyond Earth. The mission, still in the conceptual stage, would use a spacecraft to measure the wobbles of Uranus's moons, as moons with internal oceans tend to sway more due to the liquid inside. This method has previously been used to confirm an ocean on Saturn's moon Enceladus. Discovering such oceans could expand our understanding of where life might exist in the galaxy.

Researchers at the University of Texas Institute for Geophysics have developed a computer model to detect potential liquid water oceans beneath the icy surfaces of Uranus's moons, such as Ariel. This model analyzes the wobbles in a moon's spin to determine its internal composition, which could indicate the presence of subsurface oceans. The findings could significantly impact our understanding of where life might exist in the universe, as similar techniques have confirmed oceans on Saturn's moon Enceladus. The research aims to aid future NASA missions to Uranus in detecting these hidden oceans.

Scientists have discovered evidence suggesting that dwarf planets Eris and Makemake, located in the Kuiper Belt, may have warm oceans beneath their frozen surfaces. Data from the James Webb Space Telescope revealed isotope ratios in methane on their surfaces consistent with internal heating, indicating the presence of potential subsurface oceans. These findings challenge previous assumptions about the dynamics of the outer Solar System and suggest that conditions for microbial marine life might exist in the Kuiper Belt, making it more dynamic and potentially hospitable than previously thought.

NASA has launched the PACE satellite to study the world’s oceans and atmosphere, aiming to provide detailed data on temperature-related changes, aerosols, and phytoplankton. The satellite will map the entire world each day with two science instruments and collect monthly measurements with a third instrument. PACE is expected to help scientists improve their ability to predict severe weather events and understand the impact of aerosols on clouds and climate. The mission follows the recent launch of NASA’s SWOT satellite and is part of the agency's efforts to gather more detailed data on Earth's environment.

Scientists have discovered a new species of jellyfish, named "Santjordia pagesi," with a bright red "X" on its stomach in a deep-sea volcanic structure south of Tokyo, Japan. The creature, which has 240 tentacles, was first spotted in 2002 and is relatively small compared to other deep-sea medusae. The unique red cross is believed to be related to capturing food. Despite the rarity of the discovery, the species was named and described based on the capture of just one specimen due to the inhospitable environment, and researchers hope to conduct further research in the area, which has potential for commercial development.
