Interstellar Comet 2I/Borisov Update For October 12, 2019

Interstellar Comet 2I/Borisov Update For October 12, 2019


The story of the first confirmed interstellar
comet, comet C/2019 Q4, or now designated 2I/Borisov, continues to develop. Unlike Oumuamua which was caught on its way
out of the solar system leaving not much time for study, Borisov is on its way in and the
observations are well under way already, with more planned for it’s closest pass to the
sun on december 8, where it will pass between the asteroid belt and Mars. The first paper that’s come to light recently
is an observation of the surface chemical composition of the object. Done by scientists at the Gran Telescopio
Canarias in mid-september, links to all mentioned papers below, a low-resolution preliminary
spectrum of the comet was obtained. This showed that the object was surprisingly
similar in surface composition to solar system comets. As more detailed spectra are taken, we’ll
get a more detailed description of the surface chemistry of the comet. But, at first glance, it looks more or less
like something you’d find in the outer solar system. And it’s also been determined that the object
is similar in age, coming in at about 4.6 billion years old, perhaps only a little older
than our star system. The similarities were bolstered In another
paper by Alan Fitzsimmons and colleagues, where they detailed the detection of cyanide
gas coming off of the comet, which is not unusual for regular solar system comets. In fact Halley’s comet exhibited it. All of this suggests that the process for
forming comets is likely to be very similar in star systems across the galaxy. This is not surprising, natural processes
generally can be expected to happen in a similar way all over the universe, but there’s probably
still room for surprises regarding the composition of this object. The other development is more tentative, but
still interesting. Borisov’s trajectory is not perfectly zeroed
in yet, and there may be minor changes to that as it’s studied more in depth, and
that could change this part of the story. But there is now a tentative candidate system
for the origin of the object. This is usually very iffy stuff, it’s basically
working the object’s trajectory backwards is like trying to reconstruct a game of pool,
at some point it becomes impossible. But in this case, the researchers,link to
the paper below, seem to have compelling evidence that the object did not merely pass through
that system, but rather originated from that star system Known as Kruger 60, the star system in question
is a binary system and it lies just over 13 light-years from earth. The system consists of a pair of red dwarfs,
a situation which could certainly kick material out of the system. Oddly, if Borisov did come to us from that
star system, it’s not the only thing that’s coming our way from it. The star system itself is expected to have
a close encounter with the sun in about 88 million years where they will pass just under
two parsecs from us. If humans are still around and had continued
to advance, it’s easy to imagine that we’ll be that far out in space exploration by that
time and may well visit, or even colonize Kruger 60. As far as Borisov, we should get an unprecedented
detailed look at this object, and it seems like the scientific community will try to
make the most of it. For example Hubble Space Telescope imaging
of the object begins on October 8 when it moves out of the sun’s glare enough for
the HST to observe it safely. This should give both detailed views of the
comet, but also allow scientists to constrain the size and shape of the comet, as well as
details on the evolution of the outgassing as the comet passes its closest point. After that, the object should be observable
until about September of 2020. Unfortunately, even though Borisov was discovered
by an amateur astronomer, it will likely never get bright enough to be observable with the
naked eye, but should be visible in at least larger amateur telescopes,and many of those
folks will likely be photographing the object. But it does bolster the idea that we are bombarded
by interstellar objects regularly, and we only just now have the equipment to discover
them. But the study of these objects will open up
a new window into the milky way and it’s star systems, even to the point of visiting
these representatives of them as newer more powerful rockets come online. Imagine being the first person to set foot
on an object from another star system. Thanks for listening! I am futurist and science fiction author John
Michael Godier currently informing the listenership that I will not be the first person setting
foot on an interstellar object. I’m needed here on earth for such things
as helping making sure the world’s coffee supply doesn’t get out of hand, along with
management of the granola bar population and thinning the pastry herd. And then there’s my involvement with the
utterly fruitless attempt at spray can nacho cheese eradication. It truly is a labor of love and be sure to

  1. John also spoke to Angelos Tsiaras this week about the discovery of water vapors on an earth like exoplanet: https://youtu.be/2-cyPQHGsp8

  2. Every observation confirms how "normal" this new object is, in sharp contrast with 'Oumuamua. That tells me that 'Oumuamua is a very unusual object.

  3. Thanks for the update. I am also dedicated to the noble cause that is, the cull of caffeine and pastry populations. Keep fighting the good fight 👍

  4. Awesome vid!
    A Hint: to get stresses in Slavic names right you can use Google Translate text to speech functions. They do it right more often then not.

  5. Hi John, thank you for the video, really interesting and job you're doing is great. One remark to this video – please check the microphone, your voice is to quiet in the end. Thanks!

  6. If you want, I think you could totally get away with starting to drop some of those hilarious jokes during the main video content. Same deadpan, just brief little clauses in passing. It'd be super funny and it'd make us all listen even closer. And it wouldn't be confusing or anything or detract from the educational value, not with your humor style. I bet nobody would mind. 🙂

  7. Thanks for this update. One note, the music is nearly drowning out your voice. It's become a voice under in this one 🙂

  8. Hey, John, the background music was a bit loud in this one relative to your voice. I found myself having to concentrate unduly just to hear you but I still ended up missing some syllables here and there. I'd like to hear your news, not your musical filler. Thanks in advance.

  9. Considering the preliminary observations of it’s composition and age, once again, couldn’t this just be an Oort cloud object that was disturbed, and sent toward the inner solar system?

  10. An interstellar comet doesn't feel right. Consider this. Our own solar comets lose mass as they near the sun. They may pick some back up on their apogee, but not enough to rebuild the loss by the passage. Consider Halley's Comet. A site from Vanderbilt calculates that a comet the size of Halley's can last about 95 orbits or roughly 7,220 years.

    Granted an interstellar comet isn't getting heated by the Sun or any star it passes. However, the solar system is a veritable Garden of Eden compared to the interstellar medium. I find it hard to grasp that such an object could survive the interstellar medium without being eroded long before it got to us.

    Omuamua is different, it's a solid chunk of rock and doesn't outgas or shed mass like a comet does.

    Perhaps another explanation of the orbit is that it got a gravity boost by a KBO or Oort Cloud object that increased its velocity to seem that it is from another system. We do it all the time with our own probes.

    I'm not saying they are wrong, only that it doesn't feel right.

  11. If we start detecting interstellar objects like this on a regular basis, what does that mean for interstellar travel in the future? One or two objects every few decades is no big deal, but one every year or so means interstellar space is full of debris.

  12. Recently discovered event horizon which also led me here, so glad I've found you John! I've fallen in love with your videos.

  13. spray can nacho cheese,,,, u had my hopes up. I thought u meant like spray paint… I think ive always heard that stuff referred to as "squeezey cheese" whatever thats supposed to mean

  14. Fuckin big Mike. You the man my guy. Interesting topic. I honestly forgot bout bori thanks for the reminder big Mike and awsome video my guy

  15. Thanks for the video John I wonder if you would be able to see it from Mars? It would be neat if some of the Mars orbiters could get some images. Your diet sounds similar to mine John. 😂

  16. So when do we get an audible version of your book? I never have time to sit down and read so I rarely buy books. Looking forward to a posable release date.

  17. What if Oumuamua really was a scouting probe looking for signs of intelligent life. And now Borisov is an auxiliary drone to coming in to confirm what Oumuamua saw. And they were created by a race of warlike extraterrestrials intent on wiping out all intelligent life in the galaxy except themselves.

    Europa is fucked.

  18. I definitely agree with you JMG, that overseeing the coffee and granola bar supply here on earth is a definite priority over being the first guy to walk on an interstellar object. I'm on your team.

    Great upload!

  19. It will inevitably discover how truly dangerous humans are and bugger off just like Oumuamua. We are a very dangerous species and should be observed from a great distance!

  20. How do they estimate the age of a comet from interstellar space? lol
    And that ladies and gentlemen is an example of what is wrong with the current astronomical science of our time. Nothing but thin air.
    I hope that the Safire project will be start of a much needed change. Because it is getting ridiculous right now.

  21. Can NASA Stop, deflect destroy Asteroid/meteorite with dia 350-500 Impact in ocean in the coming years? speed of approx 39,009-59,000 miles per hour

  22. We are the Borg…resistance is futile..all independent thoughts will be assimilated…you will join the hive mind…you will think what we tell you…

  23. Most folks never think about space and I have found it quite fascinating after having met and talked to Eugene Shoemaker over thirty years ago Who now R.I.P

  24. Great video John , is it also possible that the events at Sagittarius A could have expelled and destroyed planets sending debris in our direction hence the unbelievably rare Interstellar objects traversing our solar system ?

  25. OMG a dwarf star system passing within 2 parsecs!!!!! Do I need to build a bomb shelter?? [Looks up how big a parsec is] Oh never mind.

  26. I am happy to do my part to help keep the coffee supply from becoming overwhelming as well. 🙂 Great video man. Love it.

  27. Soooo glad to get a new JMG video….I love Even Horizon…with it's amazing audio intro and amazing visuals…..but man….it's been too long a time to not see a down to earth JMG video….. Thank you Mr. Godier!!!!

  28. If you’re still around that long it’ll be that movie Idiocracy, only stupid people will be breeding🤪🤪🤪🤪😜

  29. It will be fun to learn of all the ways this object interacts with the energy from our sun!
    Hopefully the discussion remains open-minded and objective. Cheers!

  30. I always feel disappointed when you give time frames in millions of years! i'm the same with Christmas…. i just don't like waiting! LOL

  31. Wait, if this object is interstellar yet it has a close composition to our own system's comets, then Oumuamua is an alien ship

  32. Hey man. You should name your YouTube channel and turn it into a brand. You have great videos. Secure Team is going down hill and YouTube needs a number 1 space and extraterrestrial reporting channel. Best of luck 😁

  33. I love this youtube channel i have learned alot plus john you have the most soothing voice i sometimes go to sleep on a night listening to your videos . Look forward to more from you . 👍

  34. What if the outgassing or debris field inside the immediate coma of it contained the mathematical information outlining the DNA patterns and detailed mapping information of a far off civilization? Now that would be awesome!

  35. It would be so epic if the Comet Borisov suddenly erupted a nice tail! I guess it will pass to far away from the sun to have any chance of significant comet tail?

  36. How is it impossible to reconstruct a game of pool when we have literally TONS of pool video games. Weve had those physics figured out for a long time now. Bad analogy.

  37. Doubt "setting foot on it" would make much sense for the szie of the effort. Comapred to a unmanned mission which is hard (impossible) enough with these very fast object on very alien trajectories.
