Not every supposed northern light is a real aurora

A normal aurora (left) consists of glowing curtains of red, green and blue. An “enhanced aurora” (right) contains a thin, brighter layer that...

CO₂ poverty could reveal the ease of living

Compared to its neighboring planets, the Earth has a low CO₂ content in the atmosphere, which is mainly due to the binding of the...

Supernovae provide new data on dark energy

The Dark Energy Survey measured the distance and redshift of almost 1,500 supernovae. This provides information about the cosmic expansion and the effect...
