Images From Hinode Offer New Clues About Our Violent Sun
(NASA News) - December
- Instruments aboard a Japan Aerospace Exploration Agency satellite
named Hinode, or "Sunrise," are returning extraordinary
new images of our sun. The international mission to study the
forces that drive the violent, explosive power of the sun launched
from Japan in September.

from the Edge of the Solar System

day, the great antennas of NASA's Deep Space Network turn to
a blank patch of sky in the constellation Ophiuchus. Pointing
at nothing, or so it seems, they invariably pick up a signal,
faint but full of intelligence. The source is beyond Neptune,
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.

After a long quiet spell without any strong solar

Storms: Nowhere to Hide from SOHO's Improved 'X-Ray Vision'
(NASA Feature)- March 9, 2006
researchers using the Solar and Heliospheric Observatory (SOHO)
spacecraft have developed a method of seeing through the sun to
the star's far side. The sun's far side faces away from the Earth,
so it is not directly observable by traditional techniques.

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
program and the National Science Foundation funded the research.
