Scientists have combined NASA data and cutting-edge image processing to gain new insight into the solar structures that create the Sun’s flow of high-speed solar wind, detailed in new research published today in The Astrophysical...

NASA's extensive fleet of spacecraft allows scientists to study the Sun extremely close-up - one of the agency's spacecraft is even on its way to fly through the Sun's outer atmosphere...

Using data from NASA's Solar Dynamics Observatory, or SDO, scientists have developed a new model that successfully predicted seven of the Sun's biggest flares from the last solar cycle, out of a set of nine.

from NASA Dec. 17, 2019 NASA’s Solar Dynamics Observatory has observed a magnetic explosion the likes of which have never been seen before. In the scorching upper reaches of the Sun’s atmosphere, a prominence — a large...

Are we in a solar grand minimum? We’ve seen this before, but now predictions are for an extremely weak solar cycle ahead. Today is the summer solstice in the northern hemisphere. The sun has been without a single observable...

San Francisco – After a year of observations, scientists waited with bated breath on Nov. 28, 2013, as Comet ISON made its closest approach to the sun, known as perihelion. Would the comet disintegrate in the fierce...

Note: See updates below for the ISON ISOFF ISON nature of this comet that has everybody guessing. Picture at right also updated to reflect the new “zombie” status of this comet. Looks like ISON has disintegrated...

Looks like ISON has disintegrated during its turn around the sun. Given the radiation (estimated temperature 5,000F/2,760C – hot enough to vaporize rock), solar wind, and the tidal-forces (smallish, thanks Gavin) associated...

Above: note the four separate events in the last two days – from the WUWT Solar Page (From NASA’s Spaceweather.com) When the week began, the sun hadn’t unleashed an X-flare all year long. In only two days,...

Spectacular three year time lapse video from the Solar Dynamics Observatory In the three years since it first provided images of the sun in the spring of 2010, NASA’s Solar Dynamics Observatory (SDO) has had virtually...

Have we hit solar max? NOAA’s SWPC recently updated their solar metrics graphs, and it seems to me like we may have topped out for solar cycle 24...

NOAA SWPC has updated their plot page of solar metrics, and the slump continues. At spaceweather.com Dr. Tony Phillips writes: SO THIS IS SOLAR MAXIMUM? Forecasters have long expected the Solar Max of 2013 to be the weakest...

The latest solar cycle update graphs have been released by the NOAA SWPC today, and the anemic cycle 24 continues: The current count isn’t keeping up with the prediction line in red...
