A century of eclipses
Between 1969 and 1971, NCAR scientist John Eddy set out to archive an important part of the history of both photography and astronomy. Eddy collected more than 100 pictures of total solar eclipses taken from the late 1800s into the mid-1900s.

Blue skies—and more data
NCAR’s Coronal Multichannel Polarimeter (CoMP) found a new home early this year on Hawaii’s Mauna Loa, a high-elevation paradise for astronomical observers.

Satellite imagery helps scientists study Sun’s plasma jets
Solar scientists have long debated why the Sun's corona, or atmosphere, is millions of degrees hotter than its surface. Images retrieved by the Hinode satellite, launched in 2006, are shining some light on this paradox.

Looking within the min
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.

A new model of the Sun’s open magnetic flux
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.
