Camera related question when filming the sun

Hi, I would like to ask about something I don't quite understand.  When filming the sun with my sony digital camera dscw800 I get this vertical light beam.  I heard that these are caused by the sensor but i also notice that this  vertical beam of light gets distorted at some points.  But what I find amusing, is that when comparing it to a picture from ISS (international space station) the exact same thing happens, with the addition of a halo formed at the edges of that light distortion.  Anyone have a an explanation for this?  Thanks.
I share a comparison image, to the left is when I film the sun with my camera, and to the right when NASA films the sun from ISS.

"Visible artifacts, usually in the shape of the lens iris, are formed when light follows a pathway through the lens that contains one or more reflections from the lens surfaces."

"The spatial distribution of the lens flare typically manifests as several starbursts, rings, or circles in a row across the image or view. Lens flare patterns typically spread widely across the scene and change location with the camera's movement relative to light sources, tracking with the light position and fading as the camera points away from the bright light until it causes no flare at all."

"Uncontrolled light causes lens flare. This can be light that's reflected from internal lens surfaces, or that's scattered by imperfections in the glass."
"f the flare is badly controlled, it will produce the dramatic lens flare artifacts ..."
"Lens flare is caused by a bright light source (such as the sun) shining into the lens (whether in the image or not) that has its light reflected and scattered inside the lens causing a wash out or a flare artifact. All lenses will be subject to this to a greater or lesser degree, but this most commonly manifests with wider angles."

Other possible causes:
A dirty lens (something smudged on it like a fingerprint)
The reflective nature of the lens. High quality glass is usually coated to prevent as much reflection off the lens as possible.

What you are seeing is called a lens flare. Yes, it is caused by the lens. One way to avoid it is to use a filter and depending on the angle a lens hood would help. This is not uncommon when pointing directly at a light source.

so the dark halo from ISS is a lens flare caused by the camera lens? I am sorry friend, I don't understand the science behind this

An explanation you want, an explanation you shall get.

"Lens flare, also called veiling glare, is caused by light reflecting inside the lens, either from lens surfaces or from internal components in the lens. At every lens surface where the lens meets air a certain amount of light will be reflected. Modern lens coatings have reduced the amount of this reflection, but none can eliminate it."

that wasn't what I asked, but I guess an explanation is an explanation regardless. Well, what can I say, thanks friend...I guess

1) How is the camera lens producing a halo
2) why the vertical light beam gets distorted, you can clearly see it gets thicker at one point and after

How are these related to the camera... that's what I am wondering

If that is lens flare what the hell is this. Please help? [video="https://m.youtube.com/watch?v=b-xRhuym8cE&feature=youtu.be"][/video]

That looks like you are shooting through a window?
The bright green line was lens flare, the rest is reflection off the window.

The Purple spot in the centre of the sun is known as the "black sun effect" In simple terms it is the censor over clipping, and over compensating. In short, pointing a camera at the mid day sun results in the lens having the same effect on the sensor as the sun had on the ants some of us used to zap using a magnifying glass as kids!.... However, this can sometimes depend on the camera being used.
