The Denver UFO: Yup, It’s Unidentified… So What Does That Mean?

Posted by mattusmaximus on November 18, 2012

Over the last few days there has been a media sensation built up around a UFO in the Denver, Colorado area.  Here’s a closeup of the object in question:

The story has garned a great deal of attention, as evidenced by this video clip from a local news station…

Indeed, the news team does a so-so job of investigating this UFO, though there is a lot of sensationalizing in the report (surprise, surprise!), but there is one point I would like to emphasize in greater detail which this report totally glossed over.  That is the fact that this thing, whatever it is, is unidentified… as in Unidentified Flying Object.  Repeat after me three times: unidentified flying object… Unidentified flying object… UNIDENTIFIED flying object!!!

I want to be very clear on this point because, as I expected, the Internet is already abuzz with talk of alien spacecraft, government cover ups, and conspiracies galore.  And those leaping to this dubious conclusion (that the thing is “obviously not of this world”) are committing what is known as an argument from ignorance – that is, in one breath they will admit that we don’t have enough information to conclude what it is, but then in the next breath they will say, quite emphatically, that it HAS to be an alien spacecraft.

And such thinking contains a direct contradiction: the argument basically says that because we don’t know, then we know.  With reasoning as loose as this, one can “justify” the existence of leprechauns, Flying Spaghetti Monsters, or Invisible Pink Unicorns!  What the heck is wrong with saying “We don’t know” and just leaving it at that?

Incidentally, while the possibility of a plane or helicopter has been ruled out, it is likely that the object in question is a bug of some kind.  There is a very good article on this point over at the Illuminutti blog…

… OK – everybody now… it’s bugs.  This bug-UFO is especially bad because on some of the shots the insect actually hovers and moves around like an obvious insect. The videographer did not notice them because they were small fast-flying insects. Or perhaps they did notice the insects, but did not connect them to the unfocused black dots buzzing about on the video. It is also possible they know exactly what they are, but is just pranking  the local news station (hence the anonymity).

One or two shots in there are probably birds. You can see an apparent wing flap. Birds and bugs are common sources of UFO artifacts in the video age. They are small objects close to the camera that will appear as out-of-focus dots and streaks that can be mistaken (by the willful or truly incurious) for objects that are large and farther away. The fact that no one saw them live and there was no radar tracking should be a clue, but for the believer can just add to the mystery.

The lameness of this video being presented in breathless terms as a compelling UFO might have something to do with the declining interest in UFOs. Anyone with a genuine interest – enough to join a UFO group and try to find real evidence that UFOs are visiting ETs, would probably get tired of all the bugs and lanterns after a while. …

“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.

Alien Life in a Meteorite? Ummm, Not So Much

Posted by mattusmaximus on March 13, 2011

Last week the media was all abuzz about a story that a NASA scientist had discovered “definitive evidence” of alien life in a meteorite.  In fact, they apparently even had photos of the little critters…

Here’s the headline:

NASA scientist finds evidence of alien life

Aliens exist, and we have proof.

That astonishingly awesome claim comes from Dr. Richard B. Hoover, an astrobiologist at NASA’s Marshall Space Flight Center, who says he has found conclusive evidence of alien life — fossils of bacteria found in an extremely rare class of meteorite called CI1 carbonaceous chondrites. (There are only nine such meteorites on planet Earth.) Hoover’s findings were published late Friday night in the Journal of Cosmology, a peer-reviewed scientific journal.

“I interpret it as indicating that life is more broadly distributed than restricted strictly to the planet earth,” Hoover, who has spent more than 10 years studying meteorites around the world, told FoxNews.com in an interview. “This field of study has just barely been touched — because quite frankly, a great many scientist [sic] would say that this is impossible.” …

The “field of study” to which Dr. Hoover is referring is astrobiology, and it is a legitimate scientific endeavor that attempts to study the question of life beyond Earth.  Unfortunately, Dr. Hoover is somewhat of a crank, and his claims are quite overblown, as evidenced by the ruthless criticism he and the “peer-reviewed” Journal of Cosmology received from the wider scientific community.  Here are just a few samples of how these trumped up claims of “alien life” simply wither under scrutiny…

Bill O’Reilly Doubles Down on the Stupid: “How’d the Moon Get There?”

Posted by mattusmaximus on February 2, 2011

Recently, I’ve posted about how Fox News personality Bill O’Reilly displayed a great deal of scientific ignorance when he tried to argue that God exists because “we cannot explain the tides”.  Of course, scientists do know how the tides work (as astrophysicist Neil deGrasse Tyson states: it’s gravity from the Moon, duh); but rather than admit his error, Bill O’Reilly has decided to double down on the stupid.  Just watch this…

Once again, O’Reilly makes the all-too-common argument from ignorance, specifically the god-of-the-gaps argument. Of course, we actually do have scientific answers to many of the questions brought up by Mr. O’Reilly.  Let us examine some of his statements/claims… Read the rest of this entry »

The Blurring of Science With Media Spin: NASA’s Announcement About “Arsenic-Based Life”

Posted by mattusmaximus on December 11, 2010

I have to say that last week I was pretty upset with NASA, because – if you recall – there was a lot of hay being made by NASA about a big scientific discovery they were going to announce.  In the process, there was a great deal of media spin & speculation on whether or not it was going to be an announcement of the discovery of “alien life” or something similar.

But when it came time for the announcement, it ended up being something quite less spectacular: it was about how a group of NASA scientists had uncovered a form of bacterial life which seems to have adapted itself to living in the harsh conditions of a lake laced with heavy concentrations of arsenic – the original NASA press release can be accessed here.

NASA has made a pretty big deal out of this discovery, but there are some problems with how they’ve rolled it out, in my opinion.  I am of the view that they’ve oversold this thing, with overly dramatic phrases (from the above press release) such as…

NASA-funded astrobiology research has changed the fundamental knowledge about what comprises all known life on Earth.

and…

This finding of an alternative biochemistry makeup will alter biology textbooks and expand the scope of the search for life beyond Earth.

Upon hearing about this discovery, and not being a biochemist or evolutionary biologist myself, I decided to look past the spin being put on this by both NASA and the news media in general and go to people who know the field far better than me.  In a short amount of time, I found a great post by PZ Myers over at Pharyngula on the matter, wherein he states, among other things…

It’s not an arsenic-based life form

… I finally got the paper from Science, and I’m sorry to let you all down, but it’s none of the above. It’s an extremophile bacterium that can be coaxed into substiting arsenic for phosphorus in some of its basic biochemistry. It’s perfectly reasonable and interesting work in its own right, but it’s not radical, it’s not particularly surprising, and it’s especially not extraterrestrial. It’s the kind of thing that will get a sentence or three in biochemistry textbooks in the future. …

… So what does it all mean? It means that researchers have found that some earthly bacteria that live in literally poisonous environments are adapted to find the presence of arsenic dramatically less lethal, and that they can even incorporate arsenic into their routine, familiar chemistry. …

… This lake also happens to be on Earth, not Saturn, although maybe being in California gives them extra weirdness points, so I don’t know that it can even say much about extraterrestrial life. It does say that life can survive in a surprisingly broad range of conditions, but we already knew that. [emphasis added]

And, unfortunately, it seems that the story could get worse for NASA, because if you know anything about how the scientific community operates, you know that when someone makes a really bold claim (such as how the NASA researchers did) then other scientists are going to want to review the work & offer criticism.  Well, upon doing so, there has been some quite withering criticism coming from many DNA & biochemistry experts about the manner in which the NASA researchers conducted their work…

The Skeptical Teacher Talks About “Ghost Meters” on SETI Radio’s Skeptic Check

Posted by mattusmaximus on April 7, 2010

Okay, shameless plug time :)

This past Friday I had the priviledge of being interviewed by SETI astronomer Seth Shostak on SETI Radio’s monthly “Skeptic Check” segment. Apparently, Seth and executive producer Molly Bentley had caught the article that I wrote to Skeptical Inquirer magazine about the Edmund (Pseudo)Scientific ghost detector (my blog post on the subject is here) and how that once respected science teaching outlet had now decided to go down the rabbit hole of nonsense.

It’s a short interview (only about 6-7 minutes long), and you can listen to it here (fast forward to the 24:00 mark to get to my interview)…

The Pale Blue Dot — An Alien View of Earth

Posted by mattusmaximus on February 24, 2010

Recently we celebrated the 20th anniversary of a remarkable photograph that was taken by the Voyager 1 spacecraft as it began its long, slow exit from our solar system.  That photo was of the Earth, and the image was immortalized by astronomer Carl Sagan in his book called Pale Blue Dot. For a fuller story on this image, I suggest reading up on it all at this excellent NPR story.

Here’s the photo, and Sagan’s eloquent words about it…

Look again at that dot. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every ‘superstar,’ every ‘supreme leader,’ every saint and sinner in the history of our species lived there — on a mote of dust suspended in a sunbeam.

Crop Circles Predict… The End of the World?

Posted by mattusmaximus on June 17, 2009

Every now and then you run across a really silly bit of woo cross-fertilization.  Such is the case with a recent article in the UK’s Telegraph wherein the reader is told, in no uncertain terms…

Crop circle experts believe the latest pattern to be discovered, a phoenix rising from the flames in Wiltshire, may give a warning about the end of the world.

Are you kidding me?!  No, really… you must be kidding… right?  Because, knowing how these crop circles are made, no one in their right mind could seriously mean this.

Sadly, they aren’t kidding:

It’s Crop Circle Season!

Posted by mattusmaximus on June 14, 2009

Well, most of us in the northern hemisphere would call it summer, but when it comes to woo, that’s the time of year that supposedly other-worldly crop circles start to pop up.  These wonderfully wrought works of purely terrestrial art often appear overnight in farmers’ fields, yielding a variety of incredible designs…

More interesting than the designs that various (completely human) circle-makers are able to come up with and implement is the fact that many people consider crop circles to be definitive evidence of visitations to Earth by aliens! Of course, nothing could be further from the truth.
