World Space Week 2024 is in full swing, focusing on what space science can tell us about climate change; does Earth's "evil twin" Venus hold a dire tale of what happens when the greenhouse effect ...

Earth, Mars and Venus all looked pretty similar when they first formed. Today, Mars is dry, cold, and dusty; Venus has a hot, crushing atmosphere. Why did these sibling planets turn out so different?

Carbon dioxide is the main climate-regulating greenhouse gas on Earth, as it is on Mars and Venus. Its presence in the atmosphere traps heat from the sun, warming the climate.

According to these researchers’ simulations, a rise in temperatures by just a few degrees can send a planet like today’s Earth into a Venus-like runaway greenhouse effect.

Previous research has suggested various methods of transforming Mars, known as terraforming, ranging from releasing huge amounts of artificial greenhouse gases like CFCs, or shooting immense ...

A new study of ancient rocks on Mars reveals how the planet was likely uninhabitable — at least on the surface — after much of the water that once at the surface disappeared.

Carbon dioxide is the main climate-regulating greenhouse gas on Earth, as it is on Mars and Venus. Its presence in the atmosphere traps heat from the sun, warming the climate.

Still, that doesn't mean Venus doesn't have lessons to impart about climate change and the need to stymie the flow of greenhouse gases into the atmosphere.
