“Mysterious Planet-Sized Object” Is… A Planet!

Posted by mattusmaximus on December 9, 2011

A couple of days ago I came across this article titled “Mysterious planet-sized object spotted near Mercury” and it contained some shocking images.  I reproduce some of these images and related commentary from the article below…

The mystery image of a “cloaked alien ship”… the Romulans, perhaps?

… Theorists have seized on the images captured from the “coronal mass ejection” (CME) last week as suggestive of alien life hanging out in our own cosmic backyard. Specifically, the solar flare washing over Mercury appears to hit another object of comparable size. “It’s cylindrical on either side and has a shape in the middle. It definitely looks like a ship to me, and very obviously, it’s cloaked,” YouTube-user siniXster said in his video commentary on the footage, which has generated hundreds of thousands of views this week. Now, how this user was able to determine that the object was “obviously” a cloaked spaceship with no other natural explanation remains as much a mystery as the object itself. …

Note the staggering level of argumentation from ignorance here.  I like to call this sort of reasoning (if you can call it that) from various UFOologists the “alien-of-the-gaps”, because much like the related “god-of-the-gaps” argument from ignorance, what they do is find some kind of strange image and/or phenomenon for which they do not have en explanation and then they immediately give it an explanation unsupported by evidence.  In short, because they don’t know what it is, they know it’s aliens!  Huh?!

This, of course, is a direct contradiction and points out just how ludicrous the general argument from ignorance can be.  If the object is an Unidentified Flying Object (UFO), then by definition it is unidentified – which means that you admit right off the bat that you don’t know what it is!  So if you don’t know what it is then how can you suddenly turn around and, seemingly without any kind of scientifically-valid or evidence-based reasoning, state that it is an alien spacecraft?  Using such loose argumentation, I could just as easily claim the object in question is Santa Claus (but no, that would be silly).

Of course, a little more research shows that astronomers actually have figured out what this “mysterious planet-sized object” is hanging around next to the planet Mercury.  It seems the answer is that the object is… the planet Mercury itself.  Here’s a fuller explanation from the article…

Of course, there’s another scientifically sanctioned explanation for the curious images, though we’re not certain that skeptics and UFO enthusiasts such as SiniXster will endorse it. Natalie Wolchover of Life’s Little Mysteries put the question to scientists in the solar physics branch at the United States Naval Research Laboratory (NRL). They’re the people who analyze data from the Heliospheric Imager-1 (HI-1)–better known in this context as the camera that shot the footage in question.

Head NRL group scientist Russ Howard and lead ground systems engineer Nathan Rich say the mysterious object is in fact Mercury itself. And what we’re seeing in the footage is the equivalent of Mercury’s wake, “where the planet was on the previous day,” as it travels through the solar system on its natural gravitational path:

To make the relatively faint glow of a coronal mass ejection stand out against the bright glare of space—caused by interplanetary dust and the stellar/galactic background—the NRL scientists must remove as much background light as possible. They explained that they determine what light is background light, and thus can be subtracted out, by calculating the average amount of light that entered each camera pixel on the day of the CME event and on the previous day. Light appearing in the pixels on both days is considered to be background light and is removed from the footage of the CME. The remaining light is then enhanced.

So there you have it.  The object in question is basically an artifact that results from the combination of taking multiple images of that region in space over multiple days, the planet Mercury moving in that time, and processing the light in the image to enhance the coronal mass ejection to make it more visible.

What stuns me about situations like these is just how quickly so many people are willing to invoke magical thinking and jump to conclusions (the “cloaked alien ship” explanation) in the absence of any real evidence.  What is it about openly and honestly admitting that sometimes the most truthful answer is simply “we don’t know” that disturbs so many people?  That, to me, is the real mystery.

    You have your opinion and that is fine, but, you don’t have to sound like a douche bag and try and talk down to people, just because someone wants to believe in aliens or an alien ship near a planet does not make them less intelligent than you. Millions of people believe in a guy who changed water into wine with no physical evidence but a book!
