Plume

New research explains how spray from the subsurface ocean of Saturn's moon Enceladus transforms into chemically diverse ice grains. The study outlines the physical and chemical processes that shape the composition of the plume particles, offering insight into what the ocean's chemistry could mean for the moon's potential habitability.

NASA is running a research campaign examining fire-generated clouds, the towering plumes that wildfires can push into the atmosphere. These so-called pyrocumulonimbus clouds can loft smoke high into the stratosphere, affecting weather and climate far from the fire itself. The campaign aims to better understand how these clouds form and what impact they have on Earth's systems as wildfire activity intensifies.

Discussion is under way about coverage of Saturn's moon Enceladus. Popular reports have suggested that grains sampled from the moon's icy plume directly reveal the composition of its subsurface ocean, but the underlying research paper reportedly shows the grains are sorted or altered on their way out, complicating that simple interpretation. Commenters are weighing how much the plume can actually tell us about the ocean, and how press coverage may have oversimplified the findings.

A spent stage from a SpaceX rocket is on a collision course with the moon and expected to impact its far side in the coming days. The object has been drifting through space for years and cannot be steered. Scientists say the crash should throw up a plume of debris that telescopes may be able to observe, offering a rare chance to study the lunar subsurface.

Heavy tropical moisture from the Pacific is drenching parts of the central United States, bringing significant rainfall to states including Kansas and Missouri, while a new hurricane has formed in the eastern Pacific. The moisture plume, often described as a tropical connection, is being tracked by forecasters as it fuels downpours across the country's midsection. Regional outlets across the affected areas are following the storm's development closely.

New research indicates the ice grains erupting from Saturn's moon Enceladus are more unusual than scientists previously understood. Enceladus, which has a subsurface ocean beneath its icy shell, constantly sprays water vapor and ice particles into space through cracks near its south pole, and fresh analysis of this material has revealed unexpected properties. The finding adds to interest in the moon as one of the most promising places to search for life beyond Earth.

New research indicates that Earth microbes can survive in conditions simulating the environment of Enceladus, Saturn's icy moon, strengthening the case that it could potentially host alien life. Scientists say the findings boost Enceladus's habitability credentials, adding to earlier discoveries of water plumes and organic compounds erupting from beneath its frozen surface.

A fire in Fife, Washington has sent a large plume of smoke into the sky over the area, prompting attention from local residents. The Tacoma News Tribune reports the incident and is gathering details on what burned, where exactly it happened, and whether anyone was hurt. Authorities have not yet released a full account of the cause or extent of the blaze.

New findings describe how ocean spray venting from Saturn's moon Enceladus gradually freezes and shatters in space. The icy particles released from vents on the moon's south pole, which come from a global subsurface ocean, are slowly transformed by the extreme cold of space, shedding light on how Enceladus builds its famous plume and feeds Saturn's E ring. Researchers say the process offers fresh insight into the moon's ocean chemistry.

New research suggests Saturn's icy moon Enceladus makes signs of potential alien life easier to detect. The moon's subsurface ocean, sampled by NASA's Cassini spacecraft through plumes venting from its south pole, offers a promising target in the search for life beyond Earth, and the findings have drawn attention from planetary scientists.
