Greenhouse gases were the main driver of climate throughout the warmest period of the past 66 million years, providing insight into the drivers behind long-term climate change. Antarctica and Australia separated around the end of the Eocene (56 to 22.9 million years ago), creating a deep water passage between them and changing ocean circulation patterns. Some

Summary: Iron-rich rocks near ancient lake sites on Mars could hold vital clues that show life once existed there, research suggests. Iron-rich rocks near ancient lake sites on Mars could hold vital clues that show life once existed there, research suggests. These rocks — which formed in lake beds — are the best place to

Astronomers are beginning to understand what happens when black holes get the urge to roam the Milky Way. Typically, a supermassive black hole (SMBH) exists at the core of a massive galaxy. But sometimes SMBHs may “wander” throughout their host galaxy, remaining far from the center in regions such as the stellar halo, a nearly spherical area
