Geminids Meteor Shower

This year, the Geminid Meteor Shower will be visible from nearly all parts of the globe in the late hours of tonight, Dec. 13, and the wee hours of tomorrow, Dec. 14. If the night sky is clear tonight where you live, then it ought to be quite the sight to see. Incidentally, it’s asteroid parent body will be getting pretty close to the planet as well.

The Geminid Shower gets its name from the Gemini constellation, from which the meteors seem to originate when observed streaking across the night sky throughout history. Unlike most meteor showers, the Geminids do not originate with a comet. In the late 20th Century, it was found that the parent body of the Geminid meteors was an asteroid currently designated as 3200 Phaethon, which happens to leave a trail of dust and debris in its orbit that happens to intersect the orbital path of the Earth.

It is not known for sure how 3200 Phaethon got its particle trail (but the bottom-most link has some possible explanations), but apparently their showering on Earth is a relatively recent development (Jupiter’s gravity well helped twist it our way), with the first recorded reports occurring in the 17th century. It was also apparently a lot less intense then than it is now.

While the asteroid dust will burn up prettily in the atmosphere, none of the particles are probably big enough to produce meteorites, so nobody has to worry about their heads getting hit by space rocks. #200 Phaethon isn’t likely to crash into us either (but might come close enough to view with a telescope!).

Geminid Meteor Shower: Dust from an Asteroid


P.S. Sorry to be a downer, but just a reminder that tomorrow (December 14, 2017) there will be that in house vote on whether or not the FCC should repel its rulings on Net Neutrality, which currently limit service providers from blocking or slowing down access to the web unless consumers pay for premiums.




So I recently watched a pirated recording of the animated film Ice Age: Collision Course. Just like the other Ice Age sequels, it was for the most part silly, idiotic, and immature, and not in any of the ways that I would enjoy. The only reason I watched it in the first place is my nerdiness for all things prehistoric. I’d go on, but I suspect that there are plenty of other geeks on the internet reviewing low quality family entertainment, so why bother?

Though I do have one issue; is it just me, or is a lot of animation marketed towards families with children generally kind of low in both writing and production quality? Granted, what kind of writing one appreciates as a child differs from what one appreciates as an adult, and there are plenty of decent ways one can make use of limited animation, but that should NOT be an excuse to generate subpar content! Then again, I never watched a lot of cartoons when I was physically a child (not by choice), so what do I know? I guess some research will have to be done…

Anyway, Ice Age: Collision Course is a dumb movie with subpar jokes and a mediocre plot, as well as weird-ass interstellar events and anachronistic dinosaurs. However, the dinosaurs might be the one area where I might commend the creators, due to their decision to give those three antagonistic dromaeosaurid characters noticeable plumage.

Known to the general public as “raptors” thanks to Jurassic Park, dromaeosaurids were small to medium-sized predatory dinosaurs notable for their infamous sickle-clawed second toes and their close relationship with birds.

The most famous genus of dromaeosaurid is the genus Velociraptor, due to the usage of the name in the book and film Jurassic Park, which is applied to an animal that physically resembles the larger, geologically earlier, north american genus Deinonychus (Michael Crichton apparently used the name Velociraptor because he thought it was cooler. He might have also been influenced by the crazy cladistics of Gregory S. Paul, whose ideas on dinosaur classification aren’t exactly widely accepted by experts in the field).

When Jurassic Park was being produced, it incorporated all the latest technology and scientific knowledge of the time. When it was released, the audiences were amazed by how realistic the dinosaurs looked. Among other things, it resulted in Velociraptor skyrocketing from obscurity to common household term. However, the creature depicted in the film has little resemblance to the actual animal. For starters, the actual Velociraptor was about 0.5 meters high at the hip, had a very narrow skull, hands that could not pronate, a stiff tale, was probably no where near as intelligent as a primate, and (while this was not known at the time, not to mention too difficult to realistically animate at the time) it was covered in feathers. Not just down either, but full on pennaceous feathers that anchor to its arms like those on a bird’s wing.

Of course, most people associate the name “Velociraptor” with those “cool-looking” reptilian monsters they saw on the screen, and that has shaped portrayals of dromaeosaurs in fiction ever since. Naturally, palaeontologists and people who obsess over the prehistoric are a little miffed about all this, especially with how the rather successful 2015 sequel film Jurassic World did not bother to update the designs of its theropods from the first movie (they did include some new research for the other animals, but you can hardly notice it under the artistic license).

Another film that same year (Pixar’s The Good Dinosaur) generated a lot of hype among the paleophiliac community because it was supposed to feature feathered Velociraptors, only for the actual result to resemble the mohawked raptors from Jurassic Park III; they were just scaly animals with with hair-like structures down their necks and backs. I’m not going to dismiss this as it just being a cartoon; the animation and landscape rendering is so freaking gorgeous! If they could have spent that much effort on the imagery, they could have put more research into the character designs!

The closest real-life equivalent to the JP raptors that ever existed is arguably the recently discovered species Dakotaraptor steini (with genera like Utahraptor and Achillobator being close seconds). Roughly 5 meters long and with proportion similar to Deinonychus, Dakotaraptor was a late cretaceous predator from South Dakota that coexisted alongside (and competed for prey with) the infamous Tyrannosaurus rex. Studies of its forelimbs show that it had prominent wing feathers, which might have been used for display, sheltering eggs, balance when jumping on prey, and/or gliding during infancy.

The dromaeosaurids featured in the Ice Age film were probably based on Dakotaraptor, due to the time it was discovered and the hype it generated. Like the actual animal, they are bird-like animals covered with plumage and with functionable wing feathers on their forelimbs. However, they also have pronating hands and scaly stomachs, lack primaries, and are capable of flight, something no dromaeosaurid their size has any business doing. So, while I give the creators props for doing some research, I am not going to give them full marks due

A completely accurate depiction of Dakotaraptor (as accurate as current evidence allows, anyway) will be featured alongside other denizens of the Hell Creek formation of South Dakota in the up-coming video game Saurian, which aims to provide players with a truly authentic experience living as a dinosaur 65 million years ago. After watching some promotional material, I have to admit that these guys really did their homework when designing the dinosaurs.

Based on recent depictions, I’m kind of hoping that there will be a growing trend towards more realistic depictions of dromaeosaurs (and other prehistoric animals, of course) in popular media, a trend that I am expecting Saurian to initiate. For there not to be would seem to me like stagnation, and I abhor stagnation.

Talking About the Weather

According to NASA, 2016 was the warmest year on record (with the records stretching back to the late 1800), and the third year in a row to set a new record for global temperatures. The average global temperature was calculated to be about .99 degrees Celsius  above the mid-20th century mean, with the average global temperature being 1.1 degrees Celsius higher than it was during the late 19th century (coincidently, the industrial revolution happened during the middle of the 19th century).

This is a calculated global average based on data recorded across the planet; in a lot of places, weather dynamics meant that local temperatures did not get record-breaking high. The majority of the United States was not one of those places. Thanks to an El Niño weather pattern in the Pacific (meaning that the ocean was abnormally warm out there), Nearly all states experienced higher than average weather that was well above their 20th century means (Georgia was the only one to set a new record, though).

At the time of this post, I’m living in a relatively elevated area around western NY, and the last few weeks started out somewhat ridiculously mild (if I had wanted to, I could have gone outdoor sunbathing out on the mountain side during a weekend in early January), but are now properly cold and snowy. The dissipation of the El Niño means that this year should be cooler for North America than the last one; after the blizzard I trudged through to get back to my dorm, I am not too surprised.
