Researchers spot clouds in the atmosphere of big, puffy exoplanet WASP-127b

Researchers have made a rare detection of clouds in the atmosphere of an exoplanet, spotting puffs of unknown composition floating above the fluffy, puffy planet WASP-127b. Planet WASP-127b was in the news in 2018 when researchers from the Instituto de Astrofísica de Canarias (IAC) discovered it was one of the least dense exoplanets ever found and…

Clouds May Speed Up Global Warming

One of the most fundamental questions about climate change is also one of the thorniest: How much, exactly, will the Earth warm in response to future greenhouse gas emissions? The answer, scientists say, lies in the sky above our heads. Clouds are the fluffy, unlikely gatekeepers of climate change—they play a critical role in how…

Earth’s clouds are likely to increase global heating, scientists find

Home News Science & Astronomy Scientists think that clouds could exacerbate warming global termperatures. In this image you can see astronaut Alan B. Shepard, Jr.’s view of Earth that no American had seen before, looking down on the home planet from his history-making suborbital flight on May 5, 1961. (Image credit: NASA) While we see…

Clouds of Venus Too Dry to Sustain Even Extremophile Life Forms, Study Says

The recent suggestion of phosphine gas in the atmosphere of Venus has regenerated interest in the idea of life in clouds; however, such analyses usually neglect the role of water activity, which is a measure of the relative availability of water, in habitability. In a new study in the journal Nature Astronomy, planetary researchers computed…

GigaOm CEO: Cloud’s Hidden Complexity

While the CEO or CTO often drives the digital transformation effort at most companies, last year it was COVID-19, not the executive suite, that effectively called the shots in making it happen. But even as the impacts of the pandemic wane—at least in the United States and more slowly in Europe—the transformation is ongoing, and…

Icy clouds could have kept early Mars warm enough for rivers and lakes

One of the great mysteries of modern space science is neatly summed up by the view from NASA’s Perseverance, which just landed on Mars: Today it’s a desert planet, and yet the rover is sitting right next to an ancient river delta. The apparent contradiction has puzzled scientists for decades, especially because at the same…
