An Intimate Nuclear-Fusion View: Our Sun in 1440p (Quad-High Def)
( https://www.youtube.com/watch?v=sq4PlyNkm2Y )

The Sun is a main-sequence star and thus generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 620 million metric tons of hydrogen each second.

The sun is always changing and NASA's Solar Dynamics Observatory is always watching. Launched on February 11, 2010, SDO keeps a 24-hour eye on the entire disk of the sun, with a prime view of the graceful dance of solar material coursing through the sun's atmosphere, the corona.

SDO captures images of the sun in 10 different wavelengths, each of which helps highlight a different temperature of solar material. Different temperatures can, in turn, show specific structures on the sun such as solar flares, which are gigantic explosions of light and x-rays, or coronal loops, which are streams of solar material traveling up and down looping magnetic field lines.

Scientists study these images to better understand the complex electromagnetic system causing the constant movement on the sun, which can ultimately have an effect closer to Earth, too. Flares and another type of solar explosion called coronal mass ejections can sometimes disrupt technology in space. Moreover, studying our closest star is one way of learning about other stars in the galaxy. NASA's Goddard Space Flight Center in Greenbelt, Md. built, operates, and manages the SDO spacecraft for NASA's Science Mission Directorate in Washington, D.C.

It is widely believed that the Sun's magnetic field is generated by electrical currents acting as a magnetic dynamo inside the Sun. These electrical currents are generated by the flow of hot, ionized gases in the Sun's convection zone.

We know a lot about the Sun's magnetic dynamo. It has a 22-year cycle. During the first half of the cycle, the Sun's magnetic north pole is in the northern hemisphere while the magnetic south pole is in the southern hemisphere. Right around the peak of the sunspot cycle (solar maximum), the magnetic poles flip or exchange places so that magnetic north is now located in the southern hemisphere. This flip occurs about every 11 years at solar maximum.

The 22-year magnetic cycle greatly influences the most prominent manifestation of the dynamo, sunspots and active regions, which migrate towards the solar equator from high latitudes over the course of the solar 11-year "sunspot cycle". Sunspots and Active Regions are manifestations of the magnetic field generated in the Sun's interior poking through the visible region of the atmosphere. Active regions are responsible for the production of intense and violent energy burst, called flares, and events where very large amounts of hot gas, trapped by the magnetic field of the active region, are released from the Sun's atmosphere and into space, called coronal mass ejections (CMEs).

I never grow tired of this, either:

2160p60 4K UHD Movie of the Sun: Year 6 Review 171A SDO Video
( https://www.youtube.com/watch?v=HgP0e1VHBxc )

This ultra-high definition (3840x2160) video shows the sun in the 171-Angstrom wavelength of extreme ultraviolet light. It covers a time period of January 2, 2015, to January 28, 2016, at a cadence of one frame every hour, or 24 frames per day. This timelapse is repeated with narration by solar scientist Nicholeen Viall and contains close-ups and annotations. The 171-angstrom light highlights material around 600,000 Kelvin and shows features in the upper transition region and quiet corona of the sun.

The sun is always changing and NASA's Solar Dynamics Observatory is always watching. Launched on Feb. 11, 2010, SDO keeps a 24-hour eye on the entire disk of the sun, with a prime view of the graceful dance of solar material coursing through the sun's atmosphere, the corona. SDO's sixth year in orbit was no exception. This video shows that entire sixth year--from Jan. 1, 2015 to Jan. 28, 2016 as one time-lapse sequence. Each frame represents 1 hour.

SDO's Atmospheric Imaging Assembly (AIA) captures a shot of the sun every 12 seconds in 10 different wavelengths. 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 Kelvin (about 1 million degrees F.) In this wavelength, it is easy to see the sun's 25-day rotation.

During the course of the video, the sun subtly increases and decreases in apparent size. This is because the distance between the SDO spacecraft and the sun varies over time. The image is, however, remarkably consistent and stable despite the fact that SDO orbits Earth at 6,876 mph and the Earth orbits the sun at 67,062 miles per hour.

Scientists study these images to better understand the complex electromagnetic system causing the constant movement on the sun, which can ultimately have an effect closer to Earth, too: Flares and another type of solar explosion called coronal mass ejections can sometimes disrupt technology in space. Moreover, studying our closest star is one way of learning about other stars in the galaxy.

Check out the following link to a YouTube video. This video sums up much of what I have discovered to be truth.

Please watch the entire video, and pay attention to what is said. I am convinced by the data that these two men are correct. Please also share:

I am asking all who pray, to please pray for my wife. She had a biopsy this morning. It was intense, and she is now in much pain.

She has cancer, but we need to know what kind it is (there are 4 kinds). Two of three growths in her thyroid are calcified so we know that she has cancer. She will have to have her thyroid removed, either way, though. Thank you.

Due to rather rude comments, and other more civil comments, regarding my smoking a pipe or a cigar while making a good ham-radio video, I've made the split.

I have a new pipe-tobacco- and cigar-smoking channel on YouTube. Here is the link: https://www.youtube.com/channel/UCRRDB4yXKxoCLzAo-rf2YxA


I finally decided to split my YouTube channel ( https://YouTube.com/NW7US ) so that the main NW7US channel is smoke-free. 

In the split, I have made a smoking YouTube channel.  If you are interested in my VLogging, in which I share my thoughts on current affairs and life, while enjoying a premium cigar, or a pipe full of great pipe tobacco, here is my channel:

Thanks
