Happy Skeptical Valentine’s Day!

Posted by mattusmaximus on February 14, 2010

In true Skeptical Teacher form, I wanted to wish everyone a Happy Valentine’s Day, but in a way that will teach a good skeptical lesson.  I was inspired by today’s Astronomy Picture of the Day (APOD), which is of the gorgeous Rosette Nebula…

The APOD text displays why this is a nice, timely lesson in skepticism:

Explanation: What surrounds the florid Rosette nebula? To better picture this area of the sky, the famous flowery emission nebula on the far right has been captured recently in a deep and dramatic wide field image that features several other sky highlights. Designated NGC 2237, the center of the Rosette nebula is populated by the bright blue stars of open cluster NGC 2244, whose winds and energetic light are evacuating the nebula’s center. Below the famous flower, a symbol of Valentine’s Day, is a column of dust and gas that appears like a rose’s stem but extends hundreds of light years. Across the above image, the bright blue star just left and below the center is called S Monocerotis. The star is part of the open cluster of stars labelled NGC 2264 and known as the Snowflake cluster. To the right of S Mon is a dark pointy featured called the Cone nebula, a nebula likely shaped by winds flowing out a massive star obscured by dust. To the left of S Mon is the Fox Fur nebula, a tumultuous region created by the rapidly evolving Snowflake cluster. The Rosette region, at about 5,000 light years distant, is about twice as far away as the region surrounding S Mon. The entire field can be seen with a small telescope toward the constellation of the Unicorn (Monoceros).

Of course, there isn’t really a great big rose 5,000 light-years away in the sky – this is just another classic example of pareidolia, the phenomenon by which the pattern recognition programming in our brains makes familiar pictures out of otherwise random visual data (or audio data, as in the case with “electronic voice phenomenon”).  The whole point is that while our brains might dumbly fill in the gaps and give us the illusion of seeing a rose, we can think at a higher level and see past the illusion to the beautiful reality that lies beneath.
