Enceladus hosts a global ocean with water–rock chemistry, energy sources and a rich organic inventory, making it plausibly habitable over geological ages. But a search for life via plume sampling would need to be comprehensive and sensitive; a negative result could still be scientifically meaningful by bounding the circumstances under which life arises, demonstrating that habitability and abiogenesis are not the same.
Spirit’s dead right-front wheel became a makeshift shovel, scraping a patch near Home Plate in 2007 and exposing soil about 90% silica. Measurements by the rover’s spectrometers identified opaline silica consistent with a hydrothermal setting, possibly hot springs or steam vents; while the findings stop short of proving life or a single formation path, they mark strong evidence of ancient water interacting with volcanic material on Mars.
A new, actively boiling pool formed in Yellowstone's Biscuit Basin between June 14–16 after a hydrothermal explosion on June 13. The pool measures about 6.5 by 5.3 meters and sits above an 18.5-meter-long crack, with jets spouting up to 6–9 meters observed on June 18, indicating ongoing activity. Scientists captured video of the eruption and conclude the event likely resulted from ground collapse rather than a larger explosion, though it underscores the park's dynamic, hazardous hydrothermal system and is smaller than the 2024 eruption. No injuries were reported.
New modeling suggests that early Earth’s asteroid impacts fractured the crust and opened hydrothermal systems underground, creating heat, water, and chemical ingredients that could have driven the first steps toward life, potentially persisting for hundreds of millions of years and expanding the environments in which life could originate.
A small hydrothermal explosion at Biscuit Basin, Yellowstone, on June 13, 2026, created multiple new vents and steam-filled pools, with hot water reaching the Firehole River at about 194°F (90°C). By June 18 a new ground feature had become a vigorously boiling pool roughly 21 by 17 feet, and close-range monitoring captured this eruption on cameras about 100 meters away. The incident, following a larger 2024 blast, underscores the unpredictable, hazardous hydrothermal activity in the region and the ongoing need for monitoring to identify potential precursors.
A small hydrothermal explosion on June 13, 2026, at Biscuit Basin near Old Faithful formed a new gray, silt-filled pool and vent pathways with water temperatures around 185–200°F. No injuries were reported, and Biscuit Basin has been closed since 2024. Temporary seismic stations are monitoring the evolving vents as scientists note ongoing instability in Yellowstone’s hydrothermal system, including changes observed in nearby waterways.
South Korean researchers report finding 10–20 cm stromatolites beneath the Jeokjung-Chogye Basin crater, formed by a ~42,000-year-old asteroid impact, in a hydrothermal lake environment that could have supported microbial life. Mineral signatures including europium indicate hot-water conditions, with radiocarbon dating placing formation between ~23,400 and ~14,600 years ago. The discovery suggests impact craters may have provided transient habitats that contributed to early Earth oxygenation, though more research is needed and similar craters should be studied.
A study by Curtin University researchers suggests that life may have existed on Mars billions of years ago, based on the analysis of a meteorite called "Black Beauty". The meteorite contains a zircon crystal with layers of aluminum and iron, indicating hydrothermal activity on Mars 4.45 billion years ago. This discovery provides insights into early water activity on Mars, supporting the idea of past life. Elon Musk's vision of colonizing Mars aligns with these findings, as he aims to establish a self-sustaining community on the planet.
Researchers at Curtin University have discovered evidence of ancient hot springs on Mars, suggesting the planet may have had life-supporting environments 4.5 billion years ago. This conclusion comes from the analysis of a Martian meteorite containing zircon crystals, which revealed geochemical markers of water-rich fluids similar to Earth's hydrothermal systems. These findings enhance our understanding of Mars' potential to support life and its geological history.
