APOD: Infrared Orion from WISE (2015 Jan 19)

Post by APOD Robot » Mon Jan 19, 2015 5:05 am

Image Infrared Orion from WISE

Explanation: The Great Nebula in Orion is an intriguing place. Visible to the unaided eye, it appears as a small fuzzy patch in the constellation of Orion. But this image, an illusory-color four-panel mosaic taken in different bands of infrared light with the Earth orbiting WISE observatory, shows the Orion Nebula to be a bustling neighborhood of recently formed stars, hot gas, and dark dust. The power behind much of the Orion Nebula (M42) is the stars of the Trapezium star cluster, seen near the center of the above wide field image. The orange glow surrounding the bright stars pictured here is their own starlight reflected by intricate dust filaments that cover much of the region. The current Orion Nebula cloud complex, which includes the Horsehead Nebula, will slowly disperse over the next 100,000 years.

A beautiful apod, but is there an equivalent visible view available por favor? I feel a little lost here. Which way is north? And, where exactly is the Trapezium cluster? Nothing is recognizable here. That's not a complaint, just an observation and a request for help.

Just as zero is not equal to infinity, everything coming from nothing is illogical.

Infrared images can be confusing sometimes but they are beautiful! Recently I have got interested in infrared images of planetary nebulae, especially haloes.

North is to the left in this image. A widefield image by Tony Hallas covers approximately the same view but north is down.

Part of the NGC 1999 complex can be seen near the right edge of the infrared image. A visible image by Marco Lorenzi with north up.

The Trapezium isn't particularly well visible in this infrared image maybe due to the way it's been processed. It can be seen near the centre of this image by CHART32 taken with a 0.8 meter telescope.

It really looks SO unfamiliar! There is a big lesson in that: if you think you know anything, about anything, well, you only know one small fraction of it. Even applies to people!

This image covers pretty much the same field of view at more or less the same orientation.

The more you know of a complex subject, the more questions you have and the more aware of your lack of knowledge you become. Conversely, if you think you know it all, the fewer questions you have and you become less aware of your lack of knowledge.

When we study an object with different kinds of instruments, it creates a situation not unlike the blind men and the elephant. Of course, what distinguishes the scientist from the blind men in the parable is that the scientist consciously recognizes that he's only seeing a part of the whole, and tries to avoid drawing an overly broad conclusion.

Umm, no, it was Isaac Asimov.

Well, ok. If enough people on the Internet say so, then I have no choice but to accept it as a fact.

Wikiquotes says...
'Those people who think they know everything are a great annoyance to those of us who do.'
As quoted in The Mammoth Book of Zingers, Quips, and One-Liners (2004) edited by Geoff Tibballs, p. 299
It is possible, of course, that Asimov was quoting someone else and then was quoted in turn. If so, it would be interesting if the knowledgeable shared their secrets.

" Those who think they know it all--" probably first uttered in response to the cavewoman who suggested rounding off the corners of the wheel so it would roll better.

That's a secondary source. If you could view the page in the book there may be a primary source listed. Or it may simply say that Asimov said it without saying when and where he said it. It just sounds like one of those made up quotes with a famous name attached to it to me.
