A time-lapse video created by NASA shows images of the sun taken every day
over the last three years as it rises towards solar maximum - the peak of
solar activity in its 11-year cycle.

The images were taken by NASA's Solar Dynamics Observatory (SDO), which was
launched in 2010 to help in understanding the causes of solar activity and
its impact on Earth. SDO also studies how sun's magnetic field is generated
and structured, and how this magnetic energy is released into the heliosphere
in the form of energy particles and solar wind.

SDO monitors the sun daily and captures images every 12 seconds in 10
different wavelengths. The images found in the three-minute video are a
collage of two such images taken every day over the course of three years.

"The images shown here are based on a wavelength of 171 angstroms, which is
in the extreme ultraviolet range and shows solar material at around 600,000
kelvins (about 1.08 million F). In this wavelength it is easy to see the
sun's 25-day rotation as well as how solar activity has increased over three
years," NASA said in its news release.

The video shows the sun's solar activity increasing as it heads towards the
peak of its 11-year solar cycle. The images have regularly caught solar
flares and coronal mass ejections in the act. The sun appears to increase or
decrease in size during the course of the video. It is because the distance
between the SDO spacecraft and the sun varies over time.

Viewers can see partial eclipse by the moon (00:30;24), roll maneuver
(00:31;16), X6.9 Flare - largest solar flare of this solar cycle (01:11;02),
Comet Lovejoy, 15 December, 2011 (01:28;07), Roll Maneuver (01:42;29),
transit of Venus, 5 June 2012 (01:51;07) and partial eclipse of the sun by
the moon (02:28;13).

At the end of the video, it is shown how the sun appears in 4 different
synchronized wavelengths: 171, 304, 193, and 4500.

大意就是SDO已啟觀察太陽用3年,但對太陽來說不過是三分鐘一樣短暫
