Sees Comet McNaught (Mission
News- NASA) - January
image of Comet McNaught comes from the Heliospheric Imager on
one of the STEREO spacecraft, taken Jan. 11, 2007. To the right
is the comet nucleus, so bright it saturates the detector creating
a bright vertical band in the image. The comet's dynamic tails
extend up and to the left.

beyond Pluto, on the verge of the stars themselves.
Sentinels (NASA Feature)
In his 1970s
book, Space, James Michener depicted a fictional Apollo
mission that lost its crew to radiation from a massive solar
flare. He based his tale on what easily might have been but
for lucky timing: a massive flare on Aug. 7, 1972 occurred between
Apollo 16 (April) and Apollo 17 (December), mankind's last journeys
to the Moon. The event still resonates today.

On July 31st,
a tiny sunspot was born. It popped up from the sun's interior,
floated around a bit, and vanished again in a few hours. On
the sun this sort of thing happens all the time and, ordinarily,
it wouldn't be worth mentioning. But this sunspot was special:
It was backward.

researchers using the Solar and Heliospheric Observatory (SOHO)
spacecraft have developed a method of seeing through the sun to

next solar activity cycle will be 30 to 50 percent stronger than
the previous one, and up to a year late in arriving, according
to a breakthrough forecast by Dr. Mausumi Dikpati and colleagues
at the National Center for Atmospheric Research (NCAR) in Boulder,
Colo. The scientists made the first "solar climate" forecast using
a combination of groundbreaking observations of the solar interior
from space and computer simulation. NASA's Living With a Star

Humanity's epic voyages to the Moon are well known, the stuff of

Pick up Earthly Aurora (NASA press release)- September 9, 2005
A coronal mass ejection (CME) hit Earth's magnetic field on Sept.
15, but it did not spark the strong display of auroras many people
were hoping to see. In the CME's wake, however, a fast solar wind
stream is blowing past Earth and buffeting our planet's magnetic
field. This could cause mild geomagnetic storms.
Solar Flares Continue (NASA press release)- September 7, 2005
Scientists are currently tracking a large sunspot that has so far
unleashed seven major solar flares including an X-17-category blast
on Sept. 7, an X-5 on Sept. 8, and an X-1 on Sept. 9. To say this
is powerful is an understatement; Wednesday's X-17 flare was the
fifth largest ever observed.

Yesterday, Aug. 22, a pair of coronal mass ejections (CMEs) blasted

are possible today, Aug. 23 and tomorrow, Aug. 24 in Alaska and
Canada and possibly beyond.
