Phys.org / The most common planets in the galaxy don't appear around the most common stars, TESS observations suggest

Astronomers now estimate there is at least one planet for every star in our galaxy. These worlds, called exoplanets, are planets that orbit stars outside our solar system. But new research from McMaster University reveals ...

Phys.org / How rocks trap CO₂ faster: Water-driven pathway could speed long-term carbon storage

Rocks can bind carbon dioxide—and much faster than previously thought. For a long time, it was assumed that the transformation of CO2 into carbonate rock depends on very slow, time-consuming processes. According to that view, ...
