This is because Brown Dwarfs are only visible in the infrared spectrum:
Quoting: Anonymous Coward 16819164 Please explain why the brown dwarf 2MASS J16452211-1319516 is visible on a regular visible red light sensitive film plate on the palomar sky survey, not just the infrared sensitive plate?
It's the star near the center of the image here on the infrared plate:

And here's the same brown dwarf in visible red light:

It's much dimmer relative to the other stars in visible light, but it's still detectable, and that's from 39 light years away using just a regular red sensitive film plate! Yes, you do need a sizeable telescope and very sensitive imager to detect a brown dwarf that far away, but Nibiru's not supposed to be nearly that far away.
Where can I purchase an infrared telescope for backyard use?
You can't.
Quoting: ACWrong.
:m42infraredbw:
So if Nibiru existed and was a Brown Dwarf, it would be extremely difficult for anything earth-based to detect it.
Quoting: ACWrong. In addition to whatever amount of infrared light it emits, a brown dwarf star in our solar system would also reflect sunlight just fine. It reflect as much light as Uranus at worst, Jupiter at best ( [

So, what about infrared telescopes in space?
Well, there were only 3 such telescopes ever built:
Quoting: ACLMFAO! Hilariously wrong. Not that it even matters given the above, but just to show how you're wrong again let me name for you some of the infrared telescopes NASA's been involved in. IRAS, SWAS, WIRE (which failed), Spitzer, Herschel, and WISE.
There presently is no space-borne observatory capable of observing thermal infrared light from celestial objects.
Quoting: ACLOL, wut? Spitzer and Herschel both observe in the infrared.
The Hubble Space Telescope (HST) carries an infrared instrument called NICMOS that can observe in certain near-infrared wavelengths, but not at mid-infrared or far-infrared wavelengths.
Quoting: ACSo what? You can see brown dwarfs at near-infrared wavelengths. How do you think brown dwarf stars like 2MASS J16452211-1319516 got their names? Because they were discovered by the 2 Micron All Sky Survey!
Now that you know all this, watch this video:
What are Wikisky, Google sky and WWT hiding?
Quoting: ACOh good grief, if you're using those as your primary method of obtaining sky survey data then you're demonstrating a massive amount of ignorance about astronomy. It's how people like me know someone is full of shit, it's like smelling blood in the water. Here you go pal, knock yourself out, WISE all-sky survey in infrared:

If you want sky survey data, ALWAYS go to the primary source. Google sky et al are just secondary sources of the data, stitched and compressed for easy consumption by people who know little to nothing about astronomy.
