A nearby star system with two suns could potentially support an Earth-sized planet in a region where liquid water could exist, according to a new paper examining the dynamics of the system. The paper, published in the Astrophysical Journal, focuses on a binary star system called 70 Ophiuchi that is trillions of miles from Earth...
Scientists have helped solve a longstanding mystery about how Earth remained habitable after oxygen first accumulated in its atmosphere more than 2 billion years ago, providing evidence that an ancient ocean chemistry sustained life-friendly conditions. The study, published in Nature Communications, was led by researchers including UC Riverside geologist Andrey Bekker. They found that changes...
