If the last few years have seen a so-called quiet Sun, its silence has spoken volumes. Researchers have taken advantage of a raft of new sensors and a special observing campaign to learn much about what happens when the sun temporarily powers down.

The solar minimum that bottomed out from 2006 to 2010 was the longest and deepest since modern space observations began. Among other effects, it reorganized the areas of flux from open magnetic field lines that produce solar wind.

An experimental modeling study by a team of scientists that includes NCAR’s Hanli Liu (High Altitude Observatory) points to the propagation of waves upward from the lower atmosphere as a driver for variability in the ionosphere. The research is an important step toward better understanding space weather.

Travis Metcalfe, NCAR's High Altitude Observatory • How common are planets like Earth around other stars like the Sun? Are we unique, rare, or typical in that regard? Metcalfe likes asking big questions.

A new technique developed at NCAR will help asteroseismologists learn about stars from their oscillations, or “starquakes.” These variations in the brightness of stars reveal information about their internal structures.

NCAR scientists are working on a bigger, bolder version of WACCM (the Whole Atmosphere Community Climate Model), called WACCM-eXtension, or WACCM-X for short. The enhanced version extends the model to an altitude of about 310 miles.

Hector Socas-Navarro, NCAR's High Altitude Observatory • When this astrophysicist was 10 years old, he watched Cosmos, Carl Sagan's famous television series about the universe and our place in it. It was then that Socas-Navarro decided to become a scientist.
