Along with the visible light and warmth constantly emitted by our sun comes a whole spectrum of X-ray and ultraviolet radiation that streams toward Earth. A new CubeSat – a miniature satellite that provides a low-cost platform for missions – is now in space observing a particular class of X-ray light that has rarely been studied.

On June 9, 2016, the NASA-funded, bread loaf-sized Miniature X-Ray Solar Spectrometer, or MinXSS, CubeSat began science operations, collecting data on soft X-rays. Watch the video to see a low-intensity solar eruption – a solar flare – from July 21, 2016. The flare imagery was captured by NASA's Solar Dynamics Observatory; the MinXSS data shown on the right shows the soft X-rays observed in near-Earth space by the CubeSat before and during the flare.

Each type of solar radiation conveys unique information about the physics underlying solar flares. This data reveals the temperature, density and abundance of solar flare material, all critical factors for determining how flares evolve and heat the sun's atmosphere. Ultimately, solar eruptions impact Earth's upper atmosphere: X-rays from the sun can disturb near-Earth space, interfering with GPS, radio and other communication signals. The class of X-rays that MinXSS observes are particularly important for their influence in the level of the called the ionosphere.

This video shows how dynamic the solar atmosphere can become, and highlights that MinXSS has great sensitivity to observe even the weak flares. These observations exemplify the goals of the six-month mission, which began after the spacecraft was deployed from the International Space Station in May 2016 and has already met its criteria for comprehensive success. The University of Colorado, Boulder, manages MinXSS under the direction of principal investigator Tom Woods.

This video was made using MinXSS data from a low-intensity solar flare that occurred on July 21, 2016, from 1:33-2:23 UT, and imagery from NASA’s SDO. On the graph, pre-flare levels are shown in red, and the yellow line is the flare spectrum in real-time. MinXSS saw energy and brightness increase during the solar flare, which is apparent in the corresponding SDO images when a loop of solar material rises from an active region on the sun and shines brightly. Scientists use these flare measurements to trace the temperature, density and abundance of solar flare material during a flare.

"Along with the visible light and warmth constantly emitted by our sun"

The biggest lie ever told. The Apollo astronauts could see neither the Sun or stars from cislunar space. It is the solar UV/X-rays that create heat and light within the Earths atmosphere.

Oct 07, 2016
@Solon
Are you trying to say that the sun doesn't actually emit visible light? Further, that our atmosphere magically down-converts UV to a super continuum of visible white light?

Oct 08, 2016
@691Boat
If the Apollo astronauts could see nothing from deep space, then yes. And there is no magic, the processes involved are known and accepted, just not applied to what is going on in our atmosphere.

Oct 08, 2016
How is hubble able to see anything?
Any comment towards how efficient spontaneous down conversion is in our atmosphere? Based on my experience with crystals specifically designed to do so, there should be a whole lot more UV hitting the surface of earth if your claim is true.

WTF are you talking about? Of course they could see the bloody Sun! Bean destroyed a camera by accidentally pointing it at the Sun. What the hell do you think is causing shadows in the photographs? Scotch mist? Jesus, you hear some total nonsense on here, you really do.

@Solon,
Here, what do you think is being reflected in Pete Conrad's helmet visor? Mars? Betelgeuse? Strewth.

Nope, that would be this one:

"WTF are you talking about? Of course they could see the bloody Sun! Bean destroyed a camera by accidentally pointing it at the Sun."

That was from the surface of the Moon, not cislunar space. It's the fine silica dust that creates the light on the lunar surface, by way of UV excitation. LADEE confirmed that.


Oct 08, 2016
"How is hubble able to see anything?"

That's classified info still. No other space capable nation has a space telescope, ever wonder why?

"Any comment towards how efficient spontaneous down conversion is in our atmosphere?"

Experiments need to be performed. A lot of action going on out there, numerous processes at work.

"Based on my experience with crystals specifically designed to do so, there should be a whole lot more UV hitting the surface of earth if your claim is true."

Fortunately most of the nasty, to us, UV is converted to less harmful wavelengths by the atmosphere. Some particles will emit IR, fluoresce, for up to 5 minutes when hit by a UV photon.

Sorry, but you are talking absolute, scientifically illiterate crap. How do you manage to come up with rubbish like this? What are they seeing when they view the sun from the ISS? What do you think happens in space? The Sun suddenly stops emitting between 400 and 700 nm? Honestly, some people will believe any old rubbish. Do you not think you are not making a bit of a burke of yourself here? Try one of those conspiracy theory websites.

What a load of bollocks. I knew it'd be down to a conspiracy by NASA. It always is with idiots like you.

@Solon,
Here's a solar eclipse from Apollo 12, as the invisible Sun disappears behind the Earth:
https://www.youtu...56VbQRjM

And here's the invisible Sun from Voyager, as it took the Pale Blue Dot image:
https://upload.wi...er_1.png

And there are shed loads from the ISS.

Now go and take your medication and have a lie down.

Oct 08, 2016
I can well recall the interview with the Apollo 12 astronauts:
"It was incredible! There was no Sun to be seen, and then, just as it was about to pass behind Earth, we suddenly saw it! We thought we really ought to get a movie of this."

Anyone else remember that? Nah, I might have made that up. Just like Solon has been doing.

Oct 08, 2016
For the hard of thinking: the Sun emits a more or less blackbody spectrum. This has been measured both from Earth and from space. Have a look at a blackbody spectrum. It encompasses the whole visible range. Ergo, it would be impossible NOT to see the Sun from space. The keywords here are; *emits* and *visible*.

Oct 09, 2016
That's classified info still
@solonWTF?

yeah... so what is this then?http://hubblesite...=diagram

.5 seconds, 92,600 results

I guess you're google is so used to pseudoscience that it immediately went to some random conspiracy site
LMFAO

.

so, if you can't get an easily searchable well documented fact sheet or diagram/schematic by using the basic search engines, then what makes you think you can answer physics or other harder tasks that require far, far more research or knowledge?

more to the point: what does that say about your eu posts and what that actually means WRT your search abilities?

think on that a spell

Oct 09, 2016
If Solon is still around, I have a bridge to sell that he might be interested in. Just let me know.

Oct 09, 2016
The only people who know what can be seen from cislunar space are the ones who have been there.
" 219 37 05 Mattingly (EVA): I'm really surprised I don't see any stars.

219 37 07 Young (onboard): Charlie's only said 25 times it's black out there.

219 37 11 Duke (onboard): What?

219 37 12 Young (onboard): You've only said that 25 times. (Laughter)

219 37 14 Duke (onboard): (Garble) see (garble) (laughter).

219 37 15 Young (onboard): It really must be black out there! (Laughter)

219 37 17 Duke (onboard): It's really black! (Laughter)"

None of the cislunar EVA astronauts could see stars. They never took a photo of the Sun or stars from cislunar space.

There are no details of the critical optics. They won't let anyone put a regular telescope out there, ever.

Are you still talking about this unscientific crap? Never took a photo? I just linked to a movie of the Sun being eclipsed by the Earth, you idiot. That was on the way home from the moon. There are shed loads of photos of the Sun from the ISS. There are interviews with ISS astronauts talking about the view of stars up there. Evidently they could be seen by the Apollo astronauts from the back side of the moon. The solar spectrum includes visible light. How are we not seeing visible light?
Ever hear the one about the returning Apollo astronauts saying how amazed they were that the Sun was invisible from space? No, me neither.
Jesus, some of you people really are stupid. I've still got that bridge for sale, if you're interested.

Oct 09, 2016
@Solon,
Seeing as you like to cherry pick your quotes, try to find where this one comes from:

071:59:20 Armstrong: Houston, it's been a real change for us. Now we're able to see stars again and recognize constellations for the first time on the trip. It's - the sky is full of stars. Just like the night side of Earth. But all the way here, we've only been able to see stars occasionally and perhaps through the monocular, but not recognize any star patterns.

071:59:52 McCandless: I guess it's turned into night up there really, hasn't it?

071:59:58 Armstrong: Really has

Now STFU about this rubbish.

"Ever hear the one about the returning Apollo astronauts saying how amazed they were that the Sun was invisible from space?"

Ever hear of one of them being asked if the Sun was visible from deep space? What colour it was? Were prominences visible? Sun spots? They never talk about the sun, no photos from deep space. Photos with the Earth in view just mean they are looking through Earths atmosphere, which is what makes the sun visible from Earth.

"Jesus, some of you people really are stupid."

Jesus, most of you people really are brainwashed. Accepting ideas without asking for scientific proof, which includes independent confirmation. Put a publicly operated Celestron in orbit.

....Jesus, most of you people really are brainwashed. Accepting ideas without asking for scientific proof, which includes independent confirmation. Put a publicly operated Celestron in orbit.


I give up. Thick as pigsh*t. So Voyager can see it from x billion kms, it can be seen from the moon and ISS, it can be seen from the lunar module, but, according to hoaxboy, it's invisible!
Like I say, why don't you go and join the rest of the conspiracy nutters. Science isn't your strong point, is it? Photos of the Sun from Gemini, Voyager, ISS will do as proof for me, but I'm not a conspiracy nutjob. If it makes you feel better about yourself, and helps you sleep at night, then you carry on believing that the Sun is invisible in the measured visible spectrum.You aren't convincing anybody who is remotely scientifically literate. Just another EU nutter who can't understand science.

Oct 09, 2016
Here's an idea: go and stand outside on a sunny day - stare at the Sun for about 60 seconds. Come back to us and tell us about the colour, prominences etc.

Oct 10, 2016

@solon-g to logic
except, of course, those who watched the video's from the craft (personal and otherwise)... making the numbers exponentially larger than "the ones who have been there"
There are no details of the critical optics
in the 141 page pdf?
section 4-22, for starters, and then consider the fact that i only actually put up 2 of the 92,600 results - did you go through all 92,600 of those links?
didn't think so...
They won't let anyone put a regular telescope out there, ever
1- bullsh*t - there is no proof supporting your conspiracist ideation because

2- they can't stop any other nation or person with $$ from doing it without starting a war (IRL or in court), ya moron... you do know that other nations have spy and other satellites, right? what reality do you live in?

jonesdave said it best:
Now STFU about this rubbish


Oct 11, 2016
" they can't stop any other nation or person with $$ from doing it without starting a war"

Correct, so no other country is interested in having its own space telescope? Hard to believe.

Gaia: http://sci.esa.in...t-sheet/

Photometry: continuous spectra in the band 330-1050 nm for astrophysics and chromaticity calibration of the astrometry

330-1050 nm includes the visible range. Not much point including it if there is nothing to see in those *visible* wavelengths. Then again, I suppose a collection of numerous European countries could all be part of the 'invisible Sun and stars' conspiracy. And, presumably, the Russians, Chinese and Japanese will also sign up to the conspiracy if they ever realise that the Sun and stars are invisible from space, in *visible* wavelengths. Let's hope they have all got the same Photoshop skills as the Yanks.

Deary me.

@sol-g to logic
and this means, to a conspiracist that it's proof of conspiracy...LOL
it aint true

I noticed you shut up about the "details of the critical optics" - you must have actually read the pdf and realised you're an idiot

also
1 - a space born telescope is expensive, and why build one when the ones already up there are sharing data freely?

2- as shared by Jonesdave - http://sci.esa.in...t-sheet/

i guess your conspiracy is all out of fuel?
LMFAO

you do realise that the internet is freely searchable with various engines to find this data, right?

in fact, the more popular engines actually bring back a sh*t load of data proving your arguments crap... so why tailor your belief to the minimal pages with the least amount of information when the overwhelming evidence points towards the opposite direction?

feel free to be honest, though it appears you wont
