The discovery, made by a student team from Tohoku University, offers new insight into how marine organisms are responding to rising sea temperatures in the Pacific. The presence of P. mikazuki in Sendai Bay, a region once considered too cold for this genus, is prompting scientists to revisit long-held assumptions about species range and biodiversity in Japanese waters. Physalia utriculus, …

Giant frilly-mouthed jellyfish surge around British coastline  The Times Source link

An underwater videographer has just published mesmerizing footage of the world’s largest, longest, and heaviest known jellyfish species—a lion’s mane jelly. “Several minutes into the dive, I noticed a long, thin tentacle trailing overhead, stretching far beyond my vision,” John Roney wrote in a social media post. “I followed it through the darkness for over a minute before coming upon …

An underwater videographer has shared enchanting footage of a lion’s mane jellyfish during a night dive in the Salish Sea – a marginal sea of the Pacific Ocean. The creature was so gigantic that it took him over a minute to find it after first spotting its trailing tentacles.  “Several minutes into the dive, I noticed a long, thin tentacle …

FLORIDA — It is not uncommon to see a SpaceX launch, but what gives many a surprised delight is when the company’s famed Falcon 9 rocket creates the jellyfish effect. This was seen Thursday morning in many parts of the Space Coast and as far as the Tampa Bay area during a Starlink launch. What You Need To Know Meteorologist Maureen …

Parts of the Western United States were treated to a cosmic spectacle Sunday evening, as a giant streak illuminated the skies from Los Angeles to Phoenix. Minutes after SpaceX’s Sept. 28 Starlink launch lifted off from Vandenberg Space Force Station (VSFS), in California, the Falcon 9 rocket supporting the mission reached the upper atmosphere to create a phenomenon often referred …

The ocean covers most of our planet, yet much of it remains out of reach. Scientists have long struggled to study life in the deep sea. Robotic equipment is expensive, and people cannot dive to extreme depths. These issues leave entire marine ecosystems unexplored. Nicole Xu, an engineer at CU Boulder, is confident that her lab’s “cyborg” moon jellyfish can …

Understanding the wakes and vortices that jellyfish produce as they swim is crucial, according to Wu, et al. Particle image velocimetry (PIV) is a vital tool for studying flow phenomena and biomechanical propulsion. PIV essentially tracks tiny tracer particles suspended in water by illuminating them with laser light. The technique usually relies on hollow glass spheres, polystyrene beads, aluminum flakes, …

Jellyfish galaxies are rare cosmic sights where a spiral or disk galaxy trails a luminous tail of gas and new stars across space. That tail forms when the galaxy rams through hot cluster gas and loses its own fuel in a shimmering wake. Astronomers using the James Webb Space Telescope (JWST) spotted one such creature on June 23, 2025, naming …

Spaceships modelled on jellyfish, 3D-printed homes, polyamorous relationships and vegetarian diets are among the ways in which experts have envisaged making interstellar travel feasible. The ideas from scientists, engineers, architects and social theorists came in response to a global competition to develop plans for “generation ships”, self-sustaining crafts capable of supporting up to 1,500 people on a 250-year journey to …
