The interiors of stars

The interiors of stars are largely mysterious regions because they are so difficult to observe directly. Our lack of understanding about the physical processes there, like rotation and the mixing of hot gas, introduces considerable ...

Reconstructing Greenland's climate

Using ice-cores and a new isotopic method that can provide more precise temperature information, Marie Curie Fellow, Takuro Kobashi, has gained an insight into Greenland's climate history. His data suggests Greenland's temperatures ...

A changing sun, a changing climate?

The sun's impact on our planet's climate has recently been a hotly debated topic in the context of climate change. The controversy around this issue has led scientists across Europe to dig deeper into the claim that solar ...
