We've been covering the journey of the Habitable Worlds Observatory for some time now. Over the past few years, it's gone from a proposal to a relatively fleshed-out plan for how and what the next Great Observatory should ...
A new study using data from NASA's Hubble Space Telescope finds that star formation in the nearby Andromeda galaxy has undergone a 500-million-year decline, with an even steeper drop in the last 40 million years. Andromeda, ...
Low-level clouds over Earth's oceans play a prominent role in keeping our planet cool by reflecting sunlight away from the surface. But their response to climate change has been hard to model. Now, researchers at Caltech ...
Photocatalytic reduction of CO2 offers a promising approach to storing energy from intermittent sunlight in carbon-containing fuels and chemicals, thereby enabling carbon recycling. Single-atom Cu catalysts have attracted ...
Searching for extraterrestrial intelligence has so far primarily meant focusing on one particular type of signal—and that signal has normally been based on our own current cutting-edge technology. But what if that's the wrong ...
One of the challenges of searching for technosignatures (i.e., signs that intelligent life somewhere in the universe has created technology) is understanding what to look for. Technology is a very broad area, and different ...
Museums, libraries, archives and heritage organizations face a difficult problem: Many of the objects they preserve are made from materials that naturally deteriorate.
Photographs can reveal things that are otherwise impossible for the naked eye to see, be they distant galaxies or microscopic cells. Researchers at Osaka Metropolitan University have developed a practical and versatile imaging ...
UK astronomers are a step closer to playing a leading role in NASA's search for alien life in the coming decades as they continue developing one of the core instruments of the Habitable Worlds Observatory (HWO). The exciting ...
Birds can inhabit various environments with different climates and temperatures, ranging from cold polar regions to scorching hot deserts. To survive and thrive in these very different environments, they need to effectively ...
