@@itszortrax probably not. The atmosphere is denser than on earth and it's much further away from the sun. Both lower the intensity of the sunlight, making tan pretty much impossible. And I also don't think there are any other light sources around, which could cause that
we crashed it... but okay, we reached it nevertheless. most amazing was soviet landing on venus and sending photos before probe being crushed by pressure
Back when I was a kid and really intrigued by anything that has anything to do with space (especially our solar system), there was no such amazing content easily available to watch and listen either to learn something new or purely for entertainment. I'm so grateful for creators like Astrum that provide us with so much interesting content and will support them any way I can whenever I can.
I used to sit in the library for hours pouring over books about space (both local and what might lay beyond). I miss the quiet sounds of shuffling paper and the smell of the books. The internet is amazing and the amount of knowledge at hand is astounding but it will never replace those quiet afternoons spent sitting in a corner reading the books that sparked my imagination.
@@TooLameToDie there is something to the illustrations in those books. From the simple line drawings and the black and white photos of more technical books to the brightly colored pages of the more commercial pieces . The rounded, bubble like designs with the spinning artificial gravity, the Saturn series rockets and the use of simple 2d diagrams that would demonstrate entry, exit and intercept equations. Even being a kid in the 80’s and 90’s, with the more realistic science books that switched to showing more colored pictures of space and less illustrations, when I think of being a kid enjoying space, I go back to those older versions. And now I’m thinking of old Issac Asimov collection covers.
Titan made its own nitrogen bombs.... could you imagine seeing those explode throwing pieces of Titan miles in the sky!!? What a crazy universe we live in!!! I'm so excited for what else we discover on Titan and beyond!!!!!
@@abyss1997: Don't you eat, too? Do you enjoy someone being able to steal money from you for projects or, yes, to feed "lazy people?" My point is the extortion, not where the money goes after it's taken from you.
Its a shame that Dr. Sagan has been popularly replaced by a pretentious twat like Neil Degrass Tyson. They are not even comparable. Dr. Sagan taught. Tyson preaches.
@@garcemac grow up. human beings are flawed-you are, so am I and so was Carl. NDT too. NDT was a personal protegé of Carl's. He has done a lot to advance the field and scientific interest in general, just like Carl. Beyond that, you don't have to agree with or like everything the man says. i definitely don't. still, his contributions and achievements stand. unlike yours, almost certainly.
see.... not encouraging to the soul or spirit of Alex, but let's boost your ego and compare you to another great mind in this field of study. You folks definitely flock together don't ya? So is any of that stuff spewing out of the iceland volcano useable for fuel? SInce that's the goal right? Let's go to titan now and harvest materials for more rockets, more engines, more POWER.
It’s crazy how i binge watch/listen to these videos ALL day and i would barely show up to these classes half the time in high school. RU-vid is really connecting us to the best educators in the world. Giving us access to these lectures at no cost-while paying the creators!-is one of the greatest achievements in human history.
I think it is time to rename "fossil" fuels. Why would they be called fossil fuels in a place that has never had life to create fossils? Would hydrocarbon fuels be more appropriate? (Edit) I posted this before I read the other comments.
John D. Rockefeller's people came up with the name to make petroleum seem scarce and thus, more expensive than its supply warranted. It is not any more fossilized than, say, Oxygen.
IMO Cassini is one of the most successful and productive planetary missions ever. I was sad when its final dive had to happen, after following it for so many years and marvelling at the beautiful images it sent back to us.
Unfortunately the mission will not be able to visit the lakes - at least in the main duration of the mission. The lakes are way up in the north a hurdle that makes communicating with earth impossible without an orbiter which the mission lacks.
for some reason, the way it ended makes me sad, i would have much prefered if they made some attempt to land the satilite on a moon, and reclaim it in 300 years with space colonists.
Robo Bush 2069 "Mission accomplished after 12 years of fighting and over 2 billion spent, with only 2 casualties to our troops, the rock regime on Titan has finally surrendered as the wind moved their leader MethaneSample38 over the treaty paper, the populace on Titan can now be in confidence of a future safe for geological activity" *cheering*
I don't know what you do for a living, whether you are a scientist by trade or are 'just' a hard core amateur enthusiast but your videos should be a mandatory part of the national science curriculum of any country. I always liked science in school and was ok in it but most my teachers were dicks basically. At 48 I have watched all your videos and have learned more interesting things from you than from just about any other video series. If you are not a teacher PLEASE become one! Your uncanny ability to make professional videos which grab the attention of the viewer leaving them wanting more is an increasingly rare skill which is in depressingly short supply in the educational system. Keep it up and all the best to you!
Thank you, Astrum! Titan is such an enigma! I remember reading about it from the 1980's from Voyager! Imagine being on Titan . . . The dim and dense clouds-the hydrocarbon fog settling over the hydrocarbon lakes-walking on eroded water-ice and grains as hard as rock-huge, hydrocarbon raindrops, falling like snow. I want to wrap up warm, and have an oxygen supply, so I can get on a custom-made boat and sail across the hydrocarbon seas and down streams and rivers with low gravity and a dense atmosphere, allowing me to glide at times when I go too fast over any waves . . . What a world Titan would be! ❄🚤🌙
I love this comment, I envision being on Titan like this often! It drives me crazy much attention Mars gets when Titan is objectively the most interesting place in the Solar System.
Love your channel Alex. Your videos give really good insight for arm chair astronomers like me.... I always look forward to your content... Cheers mate...
Graditude tremendous I feel. So privileged and. Honered to have. Access too these. Photos. Thanks. Again. And. Again. Bless you all. That made. This. For me and. Others.
I am awed by what we see in ur documentaries of Cassini and new horizon..legends like Copernicus,Galileo ,Clyde Tombaugh would have their eyes swell up seeing these images
The thirty meter telescope in Hawaii is at risk along with the other observatories on Maunakea. This would be a good time to speak up for astronomy. Protestors have based their protest on false information and they have illegally blocked the road for over 3 months.
Well. They better start doing something then. Also its illegal to block the traffickway so technically if you ran over the protesters, yes you would get in trouble but they couldnt sue because they were illegally in the street when they shouldnt have been. Also who cares? If that location isnt providing 100% accurate information maybe it should be closed? I dont know any of that situation.
moviemaker2011z because of the situation dlnr has set up a roadblock above their roadblock. They claim the telescope will be nuclear powered and destroyed their water source and pollution their “sacred” mountain. Obviously that’s not true. They also claim it will get in the way of practicing our culture but it won’t... it’s 6 acres or 0.001 of the mountain. These people claim to speak for all Hawaiians and it’s not how all locals and native Hawaiians feel. They also claim it’s a illegal build because Hawaii they think Hawaii it not a real state. Astronomy puts over 160 million dollars a year into our states economy and gives high skill jobs. Tmt also plans to pay a million dollars a year in rent that goes to mountain conservation and office of Hawaiian Affairs, also put millions a year into our local school system. The protesters end goal is to have all observatories removed from the mountain by 2033 and that would cripple the astronomy world in the northern hemisphere, and really hurt my home and the next generation.
@@kakela2883 well, not wanting to be political so please dont take this the wrong way, but in todays time people are protesting everything because they know they can get away with any illegal crimes during these protests. If what youre saying is true then they clearly have no reason to protest this site. But people are also protesting the Keystone pipeline that will connect Canada and the U.S where we get millions of gallons of oil for free from Canada. It makes no sense because this oil gain could drop the price of gas by over 30% but because a certain individual wants it now its apparently bad despite the good it would do. I dont see a problem with building giant telescopes honestly with the amount of amazing discoveries in recent years so it makes no sense as to why they would protest it. Maybe they think their logic is valid but that still doesnt condon their illegal actions such as blocking the road. The police should have forced them off the area by now.
That's where your kind are hiding all of my missing socks, aren't you? Or, is that where you hid all the gold you had the cloud people steal from Ft. Knox in the 1960's! Just like a globalist cryptid to hide a mountain of gold under a lake of farts... *WE ARE ON TO YOU!*
Absolutely love your videos. They're informative to space nerds like myself yet still accessible to my kids. I have to say as well your voice and phrasing reminds me of Brian Cox. You wouldn't happen to be one in the same would you?
If you made an internal combustion motor to use on Titan, instead of gasoline fuel with an air intake to suck in oxygen from the atmosphere, you would need oxygen fuel with an air intake to suck in methane from the atmosphere.
Carl Sagan's 2nd last PhD student, W. Reid Thompson, got his PhD *computing* that there should be "free surface" liquid methane-ethane-nitrogen mixtures on Titan, as well as similar precipitation. He did this by using Voyager infrared atmospheric measurements, a lot of physical chemistry modeling of phase diagrams, and some laboratory experiments. Sagan's group measured hundreds of organic compounds in laboratory irradiated Titan-like gas mixtures, with mass spectrometry (Tommy Gold had an early quadrupole mass spec operated by Kelly Brower). They once even ran a particle accelerator experiment, whimsically entitled "Titan Ocean Experiment", bombarding a small container of liquid methane, ethane, & nitrogen with electrons and positrons at Cornell's Wilson accelerator. Unfortunately, neither Reid nor Carl lived to see the results of the Cassini mission, in which Reid had been a contributing scientist, both having died of (different types of) cancer.
Some people seem to be having trouble with the phrase 'fossil fuels'. The chemistry of Titan, largely methane based, are not fossilised life, but neither are fossil fuels on Earth, generally. Coal is fossilised plant matter, but oil is not actually a fossil substance. In most cases the term 'fossil fuel' simply means that it is already existing, having been created by processes taking millions of years.
Thats not really true though.... It is true that 99.999% of oil is NOT consisting of "dead dinosaur meat". But most of the oil IS in fact ancient, billion year accumulation deposits of mainly sea bacteria and algae, that have been drifting to the seabed upon death, then graduall over hundreds of millions to billions of years, have been compressed and decomposed into what we call oil. The reason for this is that you need an absolute "FUCKTON" (technical term) of biomass to compress into enough oil to be noticeable. Even all the dinosaurs / fossils that have existed wont make up even a percent of enough biomass to account for just the crude oil on earth. But the bacteria since 2 billion years back, does. So you're right in some ways, but completely wrong saying its not life, at least on earth. So wether or not the organic compounds on Titan is due to ancient / current life, who knows.
I'm still confused. I thought fossil fuel exclusively referred to biomass that had been compressed over very long periods. Fossil fuel comes from formerly living things. This is the definition everywhere I can find. What definition of fossil fuel would Alex be using which would include the non-biological hydrocarbons on Titan?
@@Baleur Yes, you're correct - in an effort to explain the difference of why Titan's methane is not likely to be a sign of any kind of life I oversimplified too much. Cyanobacteria from around 2.7 billion years ago are the most likely candidate for the existence of crude oil, but not Titan's methane.
@@LeoStaley Right. But there is an alternative theory that much of the oil and gas is abiotic, that is not produced by living things, but from some geologic process that is not clear. Its a bit of a fringe theory though.
If it were possible to stand beside these lakes, especially when it's raining, just imagine what a vista it would be. So alien, so unlike anything we've ever experienced, so awe-inspiring.
I *love* to do these thought experiments, sometimes we lose sight of the fact that these are real places. Just imagine the beauty & horror in the universe 🌌
@@ironsnowflake1076 Yes, real places that we'll never get to see, or touch, in person, and that's sad. Well, at least not our generation, anyway. Still, allowing one's imagination to run wild is no bad thing, and I suppose that's the point I was trying to make. Of course, the "horror" that you refer to may, in fact, be "beautiful" in itself. I guess that's because, as always, it depends on who, or what, is doing the observing, and besides, beauty truly does reside in the eye of the beholder. 😉
@@Turrican60 yes, I couldn't agree more. I feel very strongly (would bet my life) that there are other planets out there, brimming with life...I imagine the alien landscapes/seascapes, what life & death battles must be raging, what might it sound or smell like, the sunrises & sunsets (multiple suns?) the moons that glow in many skies (unrecognizable star patterns) stranger than we can imagine. The Earth is amazing, dinosaurs to jellyfish, who'd think our little world could be so diverse., then to think of the universe, incredibly old & enormous...boggles the mind :) Breaks my heart that we can't see it. Maybe, somewhere out there, other intelligent beings are just as curious.
@@ironsnowflake1076 So much to see, so much to be astonished by, yet all any of us have is a relatively few short years to live. Even then, I have to feel envious of our descendants as what will be common knowledge to them is far beyond our grasp. Still, I guess it's our misfortune to be born at the 'wrong' time, I suppose, though I'm not entirely convinced there's ever a 'right' time, lol. Apologies for a very late reply. 😉
