Astronomers have discovered the largest and most distant water reservoir in the cosmos within a quasar called APM 08279+5255, containing enough water to fill trillions of Earth oceans, and its brightness is likely amplified by gravitational lensing, providing insights into galaxy and black hole growth in the early universe.
Astronomers have discovered the largest and most distant water reservoir in the cosmos within a quasar over 12 billion light-years away, containing enough water to fill trillions of Earth oceans, with the observation potentially amplified by gravitational lensing, providing insights into galaxy and black hole growth in the early universe.
Scientists have detected intriguing radio signals and high levels of water vapor and ammonia from Comet 12P/Pons-Brooks during its 2024 approach, revealing its active nature and potential insights into the early solar system and Earth's habitability.
Ancient volcanic eruptions on Mars may have released water vapor that froze into ice, potentially creating significant underground ice deposits near the equator, which could be valuable for future human exploration. The study suggests repeated eruptions over millions of years could have contributed to these ice deposits, although further research is needed to confirm their presence and composition.
Scientists have observed that the interstellar object 3I/ATLAS is releasing large amounts of water far from the Sun, which is unusual and suggests it may have a significant water reservoir and unique chemistry, providing insights into alien planetary systems.
Scientists analyzing the interstellar object 3I/ATLAS found it is releasing large amounts of water far from the Sun, suggesting unusual activity and the presence of significant water stores, which challenges existing understanding of comet behavior and origins from other star systems.
Scientists have developed a new model to better understand 'steam worlds,' planets too hot for liquid water and filled with water vapor, which could help in the search for habitable planets. The model considers exotic water states like supercritical water and superionic ice, and is relevant for interpreting observations from telescopes like JWST and future missions like ESA's PLATO. This research enhances our understanding of the most common types of exoplanets and their potential for hosting life.
NASA's James Webb telescope detected water vapor on the small, hot exoplanet TOI-421 B, a sub-neptune with a clear, hydrogen-rich atmosphere lacking methane and carbon dioxide, challenging previous assumptions about such planets' atmospheres and offering new insights into their formation and evolution.
Water vapor has been detected in the disc around a young star, HL Tauri, where planets are likely forming, revealing its potential impact on planet composition. The discovery, made using the ALMA observatory, is significant as water is crucial for life and plays a key role in planet formation. The findings provide detailed images and spatially resolve water vapor at a distance of 450 light-years from Earth, shedding light on the distribution of water in a stable, cool disc, which offers favorable conditions for planet formation. This discovery has implications for understanding planet formation and the role water plays in it, with future upgrades at ALMA and the Extremely Large Telescope set to provide even clearer insights.
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have detected vast amounts of water vapor in the protoplanetary disk around the young star HL Tauri, located 450 light-years away. This discovery, detailed in a study published in Nature Astronomy, also revealed a visible gap in the disk where a planet may be forming. The findings suggest the potential for a water-covered planet to develop around HL Tauri, offering insights into the prevalence of watery worlds in the cosmos.
Scientists using the ALMA observatory have discovered an immense presence of water vapor surrounding the young star HL Tauri, located 450 light-years away, which amounts to three times the volume of Earth's oceans. This finding could enhance the potential habitability of planets forming in this region, as it mirrors the conditions present during Earth's formation. The discovery underscores the fundamental role of water in various recent scientific breakthroughs, including the detection of water leaking towards Earth's core and the identification of the oldest water on the planet.
NASA and NOAA have proposed a radical plan to combat climate change by seeding the atmosphere with ice particles to freeze water vapor and prevent it from turning into greenhouse gas emissions. The plan involves using high-altitude planes to inject two tons of ice particles into the upper atmosphere each week, aiming to cool the atmosphere by a small amount. While the idea is a part of geoengineering efforts, it is not a substitute for reducing carbon pollution and may have potential side effects, according to some scientists.
Scientists have discovered large amounts of water vapor in a disk of dust surrounding the star HL Tauri, with enough water to fill Earth's oceans three times over. This finding, made using the ALMA telescope, sheds light on the role of water in planetary system development and may provide insights into how Earth acquired its water. The discovery is significant in the search for signs of life beyond our planet and contributes to our understanding of planet formation in star-forming regions like the Taurus Molecular cloud.
Astronomers have made a groundbreaking discovery of water vapor in a protoplanetary disk around a young star, shedding light on the formation of planets. The observations, made using the ALMA telescope, suggest that water may play a crucial role in planet formation by freezing onto dust particles and aiding in the aggregation of planetary building blocks. This finding provides new insights into the early stages of planetary formation and may offer clues about Earth's own formation over 4 billion years ago.
Astronomers have made a groundbreaking discovery by mapping the distribution of water vapor in a planet-forming disk around a young star, HL Tauri, shedding light on the potential origins of Earth's water. The observations, made using the ALMA telescope, revealed a significant amount of water vapor in the region where terrestrial planets like Earth are expected to form, suggesting that Earth may have been born with a large proportion of its water. This finding could provide valuable insights into the development of planetary systems, including our own Solar System.
