Heat and Light from the Sun

I am searching for empirical scientific evidence that the Sun emits any heat (thermal infrared) or visible light when observed from outside of Earths atmosphere or outside of any other planet or moons atmosphere.
Acceptable proof would include a photograph of the Sun from clear space (not low Earth orbit) taken with the same type of equipment and exposure settings that we would use when photographing the Sun from Earths surface. e.g. film or digital camera and neutral density filter.
Direct measurement of the Suns heat using the same type of equipment that we use from Earths surface, e.g. a pyrheliometer.
Comments and observations on the appearance of the Sun from anyone who has been outside of low Earth orbit e.g. the Apollo astronauts.

Thank you.

A grade schooler's understanding of basic thermodynamics and the simple fact that the sun creating heat in our atmosphere but not outside it is impossible isn't enough?

SOHO has several instruments and we've taken photographs on the Moon. As Myraid points out, practically every object in the solar system is observed to be lit by the Sun with day/night cycles working exactly as expected.


What's the alternative idea?

Is 36,000 miles orbit sufficient? How about 1,000,000 miles?

So what's the theory here you leave the atmosphere and the sun is just... a nothing? No heat, no light.

That would explain why we canít see anything outside the Earthís atmosphere.

Also if I take a hammer outside the atmosphere does it still hurt if I smack myself in the face with it? Is there any empirical proof of this?

At first I didn't think that met the OPs requirements but now I think the WISPR camera on that probes qualifies. So, yeah.

A digital image is proof of nothing. At least with film you know that light must have struck it, even it wasn't from the Sun in outer space. But a digital 'camera' image could have been produced entirely electronically without any light being involved.

I'm surprised that you are willing to accept such dodgy evidence. Why? Because if you doubt the well known scientific fact that the Sun produces light which travels through space, why would you accept a mere photograph that could easily be faked?

That image has obviously been doctored.

Besides, how how do we know it was taken with the same type of equipment and exposure settings that we would use when photographing the Sun from Earths surface? I bet it wasn't.

Is this about some electric universe thing? Like, a hypothesis that the sun emits some kind of electric current instead of light, that only turns into light and heat when it reaches Earth's atmosphere (or anything else)?

Perhaps, but the details don't matter. The important thing is that if the Sun doesn't produce light that travels through space then Solar physicists are a bunch of incompetent fools who have been lying to us for years!

Nobody is quite sure what Solon proposes, mostly because he isn't either. Been there and done that. Had a sufficiency.

The astronauts were toting Hasselblads for all the Apollo missions. For what it is worth, those are regarded in the photograpy fraternity as "OMFG, I wish I had that many". They are the creme de la creme.

And you are correct. All of the images are available publically. At a click. And the videos.

But these are mere facts. When did those ever get in the way of a CT?

Ha. NASA was against lugging a video camera to the moon, why bring that extra deadweight?

Amusing in hindsight, but was a serious discussion at the time.

Thank you.
My advice would be for you to look at any planet, any moon, any comet, or any asteroid in our solar system because the way such objects are made visible to those on Earth is due to the vast amounts of visible light that is produced by the Sun.

Dude, you can just go outside on a sunny day and feel the sun's heat on your skin. Ever get a sunburn?

The heat and light has to travel through the space between the sun and the earth to get here. I see no reason whatsoever to have even a shadow of a doubt about this. But if you really want to see pictures of the sun taken from satellites or probes in space, you can of course google those. You don't need to ask us.

(Is this going to be a flat earth thing? Because I'm having trouble thinking of a reason why someone would doubt this, unless they don't accept the basic current scientific understanding of the universe.)

The moon doesn't have an atmosphere. I can see the light from the sun reflected off the moon. It's strong enough that it can cast a shadow.

Myriad mentioned comets, which is good.

I can also see the sunlight reflected off of satellites, which is what makes them visible.

Our satellites and space probes are solar powered, so the fact that people can survive on ISS, that your GPS works, that communication satellites function, and that at least some of those probes sent pictures back relies on the light from the sun. Some of our space probes have been nuclear powered, but I'd have to look it up to know which.

Is that enough? I could probably think of some other lines of evidence to explore if you're still uncertain.

Also astronauts' space suits when they go on space walks need air conditioners because of the sun's heat and they need special films like sunglasses to protect them from direct sunlight.

Radiolab - Dark Side of the Earth [Dave Wolf]
------------------------------------------------------------------------------------------------------------------------------------------------------
200 miles above Earth's surface, astronaut Dave Wolf -- rocketing through the blackness of Earth's shadow at 5 miles a second -- floated out of the Mir Space Station on his very first spacewalk. In this short, he describes the extremes of light and dark in space, relives a heart-pounding close call, and shares one of the most tranquil moments of his life.
When we were putting together our live show In the Dark, Jad and Robert called up Dave Wolf to ask him if he had any stories about darkness. And boy, did he. Dave told us two stories that became the finale of our show.
Back in late 1997, Dave Wolf was on his first spacewalk, to perform work on the Mir (the photo to the right was taken during that mission, courtesy of NASA.). Dave wasn't alone -- with him was veteran Russian cosmonaut Anatoly Solovyev. (That's a picture of Dave giving Anatoly a hug on board the Mir, also courtesy of NASA).

Out in blackness of space, the contrast between light and dark is almost unimaginably extreme -- every 45 minutes, you plunge between absolute darkness on the night-side of Earth, and blazing light as the sun screams into view. Dave and Anatoly were tethered to the spacecraft, traveling 5 miles per second. That's 16 times faster than we travel on Earth's surface as it rotates -- so as they orbited, they experienced 16 nights and 16 days for every Earth day.

Dave's description of his first spacewalk was all we could've asked for, and more. But what happened next ... well, it's just one of those stories that you always hope an astronaut will tell. Dave and Anatoly were ready to call it a job and head back into the Mir when something went wrong with the airlock. They couldn't get it to re-pressurize. In other words, they were locked out. After hours of trying to fix the airlock, they were running out of the resources that kept them alive in their space suits and facing a grisly death. So, they unhooked their tethers, and tried one last desperate move .

In the end, they made it through, and Dave went on to perform dozens more spacewalks in the years to come, but he never again experienced anything like those harrowing minutes trying to improvise his way back into the Mir.

After that terrifying tale, Dave told us about another moment he and Anatoly shared, floating high above Earth, staring out into the universe ... a moment so beautiful, and peaceful, we decided to use the audience recreate it, as best we could, for the final act of our live show.

If I remember rightly, he thinks there's no "light" in space, and it's something magic in the atmosphere that turns whatever it is into visible light.

Wow; since some of those links go back 9 years, I suspect weíll be unsuccessful in convincing Solon heís wrong.

The heat and light has to travel through the space between the sun and the earth to get here. I see no reason whatsoever to have even a shadow of a doubt about this. But if you really want to see pictures of the sun taken from satellites or probes in space, you can of course google those. You don't need to ask us.

(Is this going to be a flat earth thing? Because I'm having trouble thinking of a reason why someone would doubt this, unless they don't accept the basic current scientific understanding of the universe.)

I’ve seen something like this before. I think the underlying claim might be that the heat and light we feel and see is somehow caused by an interaction between (cold, dark) particles* emitted by the sun and the Earth’s atmosphere.

*ETA: What I’ve managed to find after a brief search says that it’s “electric rays” causing friction in the atmosphere, so maybe we’re in Electric Universe territory.

Myriad mentioned comets, which is good.

I can also see the sunlight reflected off of satellites, which is what makes them visible.

Possibly not if the OP thinks that the sun emits *things* which aren't light or heat which magically turn into light and/or heat once they interact with the Earth's atmosphere.

Those same *things* would be reflected from the moon or satellite and then magically turn into heat and/or light once they hit the atmosphere.

Is that enough? I could probably think of some other lines of evidence to explore if you're still uncertain.
Possibly, but of course the solar panels could contain some of the Earth's atmosphere which would convert the *things* into light and/or heat and allow them to work.

It all depends on how sceptical deluded a person is.

It's a fair cop - he got us.
