It took 10 years to create this image of our changing Sun. Taken from space by the Solar and Heliospheric Observatory (SOHO), it shows a dramatically different picture than the one we receive on Earth.
From Earth’s surface, we are treated to a biased view. Every day our world is bathed in the Sun’s light and heat, and at these visible and infrared wavelengths our luminary shines to within a fraction of a percent of the same energy every day.
At ultraviolet and X-ray wavelengths, this is not true. Launched in 1995, SOHO has been continuously monitoring the Sun since then, in part to study this variation. Back in 2006, one image for each year of the mission until then was chosen and displayed in this montage.
The bright parts of these images correspond to gas in the Sun’s atmosphere at a temperature of about 2 million degrees Celsius.
Unlike visible light, the intensity of the ultraviolet radiation from the Sun varies greatly. This variation becomes more pronounced the shorter the wavelength, especially in the X-ray region of the spectrum. This is governed by solar activity, which runs in an approximately 11-year cycle. It is linked to the generation of the Sun’s magnetic field although our precise understanding of this mechanism remains elusive.
The waxing and waning of cycle-23, counted since 1755 when systematic record-taking began, can be seen clearly in this image. At its peak in 2001, the Sun was a maelstrom of activity, releasing about 10 times more ultraviolet light than at the minimum periods that can be seen in 1996 and 2006.
Now in cycle-24, the Sun is again at a peak of activity, although it is milder than that of 2001.

Solar Halo taken from Warren Folkestone Kent.
Halo is the name for a family of optical phenomena produced by light interacting with ice crystals suspended in the atmosphere. Halos can have many forms, ranging from colored or white rings to arcs and spots in the sky.
85% Solar Eclipse viewed from Abingdon, UK on Friday 20th March 2015.
This was photographed with my 10" Dobsonian telescope and a Pentax K5 IIs.
Halloween 2003 will live forever in the annals of solar history. In the space of two weeks centred around the spooky celebration, solar physicists witnessed the most sustained bout of solar activity since satellites took to the skies.
The Solar and Heliospheric Observatory (SOHO) was monitoring it all. The ultraviolet telescope captured the climax of activity on 4 November 2003, showing a blistering solar flare bursting from active region 10486 at 19:29 GMT. Solar flares are the near-instantaneous release of energy caused by a loop of magnetism snapping into a more stable configuration.
In this process, the energy of up to a thousand billion Hiroshima-sized atomic bombs can be released in just a few minutes. That release is seen here. The horizontal white streak is where the camera has been blinded by the brightness of the flare.
Things began when a giant sunspot, fully ten times the diameter of Earth, hove into view around the western limb of the Sun in late October. It was followed by another, equally large, spot and together they moved across the face of the Sun generating flares on an almost daily basis. This image shows the second spot’s parting volley.
Solar flares are classed according to the energy they release at X-ray wavelengths. There are three major categories: C, M and X, further divided into 10 subclasses. M1 flares are ten times more powerful than C1, and X1 flares are ten times more powerful than M1 flares, or 100 times more powerful than C1.
This 2003 flare was so powerful that it broke right through the top of the X-class range, which is usually given as X10. Analysis showed that it clocked in at X28, making it 28 times more powerful than an X1.
A billion tonnes or so of the solar atmosphere was propelled into space at a speed of 2300 km/s – a staggering 8.2 million km/h.

People around the world, standing across a great swath of the Earth's surface saw the Moon take a snap of the Sun during the first partial solar eclipse of 2011.
HISTORY OF THE SOLAR ECLIPSES:

Peach County Georgia USA.
We only had about 90% totality here. The skies turned just a little dull. Amazing how bright the sun still is with only 10% visible.

DO NOT TRY VIEWING THE SUN WITHOUT SPECIAL FILTERS. EVER. Taken with DayStar Scout SS60-DS 60mm H-alpha Solar Telescope.
Notice the flares on the edge of the disc plus a a bit of detail on the Suns surface. This was my very first attempt, got to try and get better focus next time

This was about the best I could do in New Jersey - taken at about the peak of the eclipse. Clouds tried to ruin it, but the sun/moon peaked out from time to time.
I used a variable neutral density filter set all the way to dark.

I went back to Hudson River Park and the surrounding areas between 14th and 23rd Streets this weekend. I brought my shift lens this time specifically for the Solar Carve Tower and The XI.
During the early days of the Civil Space Police, they fielded the Solar Vanguard, a hybrid interceptor/perp transport.
The Solar Vanguard was mostly used on sleepy backwater worlds to apprehend rogue Blacktron agents committing minor offenses such as jay-walking, spitting, and public drunkeness.
Quick, well-armed, and holding an internal single holding cell, this is one Space Police craft not to take lightly.

The solar eclipse in April was one of my favorite moments of 2024. I was fortunate to experience totality in Maine.
Here is a compilation of the different phases of the eclipse. I'm definitley framing this one in my office.
Wishing everyone a happy and healthy new year!
I set up my camera on the roof, at an angle that would only capture the sun's track till directly overhead. There is a break in the solar line near the top, which is about right for our 10:30am 57% solar coverage. There is another small break later, and I think that is when it started getting cloudy. So is that break in the line from the eclipse? I can't say for sure, but I think so, and I'm sticking to that reality! (-:
