Today Venus has a dry, oxygen-poor atmosphere. But recent studies have proposed that the early planet may have had liquid water and reflective clouds that could have sustained habitable conditions. Researchers at the University ...
In 1992, humanity's effort to understand the universe took a significant step forward. That's when astronomers discovered the first exoplanets. They're named Poltergeist (Noisy Ghost) and Phobetor (Frightener), and they orbit ...
