New image of Neptune from the Webb space telescope

It's maybe the most beautiful celestial image I've seen yet. Fills me with awe and wonder.

Can James Webb beat this awesome image with my 8 inch telescope and cell phone?

@LunarOrbit Saturn, my telescope isn't good enough for neptune generally, Very hard to seee.
FukFaceWillie · 51-55, M
@JimboSaturn But that you can see it live (minus what, a couple of hours) is so amazing.

@JimboSaturn Very nice pic nonetheless :)
It's obvious I'm a nocturnal creature and love the cosmos, so this gorgeous image literally makes my heart smile. 💖 I'm in awe. Thank you for sharing!
@MoonlightLullaby nocturnal creatures understand the magic lure of the night sky 🌜
@robingoodfellow Yes! We have an appreciation many don't comprehend.💫

Yes that is so cool. I guess those are moons around it? James Webb is fkg awesome.

@JimboSaturn Perspective. Triton is only 220,000 miles away.
Same distance Earth and Moon
JimboSaturn · 51-55, M
@Gusman Oh I should know this being into astronomy lol. That would mean the other moons are close.
Gusman · 56-60, M
@JimboSaturn Closest is Naiad - 30,000 miles.
Naiad is only 20 miles across
Triton is 840 miles across

I do sometimes distinguish between natural light and other forms of imagery. This is really a graph of infrared radiation. It’s still incredible, though.
@FukFaceWillie Yes, it's a fine image!

Damn!!! That's beautiful!!! Like a great big lemonade ice bubble.

Neat -- a glow-in-the-dark planet. :)

Wow that's incredible

Do you know the spectral range? Is it infrared?
helenS · 36-40, F
@Gusman So it's essentially a temperature profile of the planet. Fascinating.
@helenS You got me curious, so I started looking things up. NASA says
[quote]The wavelength range covered by Webb's scientific instruments will be from about 0.6 μm to 28 μm (visible to mid-infrared light). By comparison, the Hubble Space Telescope observes at 0.1-2.5 microns (ultraviolet to the near infrared).[/quote]

Astronomers can choose one of 4 instruments at a time (I think)
1 Near-Infrared Camera (NIRCam): 0.6–5 micrometers
2 Near-Infrared Spectrograph (NIRSpec): 0.7–5 micrometers
3 Mid-Infrared Instrument (MIRI): 5–28.5 micrometers
4 Near-Infrared Imager and Slitless Spectrograph (FGS/NIRISS): 0.6–5 micrometers

Each instrument has options; here are the filter options for NIRCam

I think many of the images we see are originally "black and white" taken thru 3 or more filters sequentially, then assigned "false colors" to make a composite color image (if that makes any sense).

@ElwoodBlues Thank you!!!
And yes of course you can assign a color space to a temperature range; scientists do that all the time.
Very cool, is that aurorae?
