WISE Sees an Explosion of Infrared Light

A circular rainbow appears like a halo around an exploded star in this new view of the IC 443 nebula from NASA’s Wide-field Infrared Survey Explorer, or WISE.

When massive stars die, they explode in tremendous blasts, called supernovae, which send out shock waves. The shock waves sweep up and heat surrounding gas and dust, creating supernova remnants like the one pictured here. The supernova in IC 443 happened somewhere between 5,000 and 10,000 years ago.

Palo Alto, CA — A tiny, little-understood plant pore has enormous implications for weather forecasting, climate change, agriculture, hydrology, and more.

A study by scientists at the Carnegie Institution’s Department of Global Ecology, with colleagues from the Research Center Jülich in Germany, has now overturned the conventional belief about how these important structures called stomata regulate water vapor loss from the leaf – a process called transpiration.
