Ever since my grandfather set up his 4 inch telescope in our backyard in 1963 I've been fascinated by the glorious majesty of a pristine night sky. Saturn is also my favorite planet. Unfortunately, there is way too much light pollution now to enjoy that, but at least I can still enjoy your videos. Thank-you. Your bloopers also remind me that I'm not the only one who flubs up talking once in a while. I take from that a sort of perverse schadenfreude that even those with a vastly more extensive educational background than I possess can make mistakes too! Thanks again!

Growing up Pleiades was always my favorite star cluster, was told it was called the 'Seven Sisters'. My Scoutmaster was a HUGE fan of astronomy and had a portable telescope he would bring with him whenever terrain allowed. I was 12 when we went to West Virginia, hiked up a mountain (dont remember which one it was) and camped out. He set up his telescope and showed me the Andromeda galaxy! It was amazing, we also got to see Jupiter and Saturn with rings and moons from both. Thanks for all your vids, it has been an amazing journey watching them and learning about the field.

[@LukeChaos]

The Pleiades in Greek mythology are the seven daughters of Pleione, so "Seven Sisters" is a nice and appropriate name. Your sky watching camping trips sound awesome!

The high energy particle just reminds me of the one theory someone had of a very famous speedrun in the Super Mario 64 community where a guy was livestreaming his perspective and Mario seemed to teleport up to the top of the level. Someone had a theory that a high energy particle tripped a single byte in the games code that bugged it out and that's why Mario teleported.

[@whatthebeepvideos]

[@adamengelhart5159]

It's certainly possible--if some event flipped a high-order bit from 0 to 1 in the memory location storing Mario's vertical position, I'd expect him to just reappear that number of units above where he was on the next frame. Intel ran into an issue like this back in the '70s, but after they built a MASSIVE lead box (something on the scale of tons) to test the theory, they found cosmic rays actually weren't the problem. The truth was much stranger . . . *the single event upsets were coming from inside the chips.* Specifically, from trace amounts of radioactive elements in the ceramic packaging. They had to work out how to get the impurities down to a level where they wouldn't be an issue.

[@hubbsllc]

@@adamengelhart5159 I remember that story but I thought it was someone other than Intel - Sun or IBM? I'd been thinking that if I ever ran a data center again, I might fill some spaces in server racks with slabs of Teflon to help prevent bit-flips.

I worked in IT for 20 years or so and sometimes bugs happened that after running all the diagnostics and tests available were just inexplicable and unrepeatable. SOP was to shrug and declare "cosmic ray". No idea if it was but sometime you've just got to move on.

I know it's not quite this simple, but it should be. Hubble is like a wonderful elderly person and given us so much over the years, I truly hope we do all we can to keep it going because it will always provide incredible information no matter what, so I would love to see it still showing the next few generations of telescopes what it is truly capable of. I mean it already has and it will always be legendary! 😊 As always a wonderful video!!!

[@lepidoptera9337]

If you could get two newer and better telescopes for the price of one Hubble servicing mission, why would you waste your money on Hubble? Science funding doesn't grow on trees. It has to be worked for by the taxpayer, you know.

@@lepidoptera9337 Exactly, Hubble is amazing, but we can do much better for cheaper now. I would rather see Hubble moved to a museum orbit.

[@lepidoptera9337]

@@HicSvntDracones Me, too. Eventually we will have the means and money to capture these instruments as "tourist destinations".

[@zombiedad]

Hubble is amazing. Imagine having a car that is over 30 years old and hasn’t been serviced in 15 years and is still (mostly) going. lol. Do we know how (if/when)NASA plans to scrap it. Don’t want more space junk. A mannee we d mission has ittown bonuses though, outside the repairs.

[@MP-nz8cf]

As a newbie, it would be interesting to know what becomes of these high energy cosmic rays after they ‘hit’ the planet or detectors. Do they simply pass through and keep going unchanged, do they change their state, are they destroyed, etc?

[@RobinTheBot]

Good question

[@thamerkules8081]

Great question!!!

[@Pharisaeus]

As mentioned on the video - they collide with atoms in the upper atmosphere and create shower of secondary particles resulting from the collision. They can't go "unchanged" because in such case we would not be able to detect them at all - they have to make some interaction with the detector at least. In case of charged particles, we might detect interaction with electromagnetic field for example. But to measure the energy you often use special detectors called calorimeters which are designed to stop the particle completely in order to measure how much energy it was carrying.

[@Zouzou123gen]

Thanks for explaining​@@Pharisaeus but in my newbie mind, OP's question still remains... To rephrase: * When the first particle hits our atmosphere, how changed does it become - does it change direction, does it also transmute into another particle? * When the secondary particle hits our detector, you said it is "stopped completely" - does this mean this secondary particle disappears? * What if there were no detectors, would that secondary particle stop on the ground, or would it go through Earth and beyond? Apologies if this all seems obvious

[@Pharisaeus]

@@Zouzou123gen the direction of the secondary particles is defined by momentum of the system. Since most of the momentum comes from this initial cosmic ray, the direction of the shower will match that, although since it hit something stationary, the direction will get deflected to some extent. It's a bit tricky to define precisely what will happen to the particles, there are many options, but it might be the easiest to assume that following e=mc2 it will turn into pure energy and then new particles will be created from that energy. You can't really destroy matter, at best you can turn it into energy. Most heavy particles interact with matter, so they would be stopped when reaching the ground eventually. However, something like neutrino could pass through.

Can you make a video that explains why planets have to form in resonance and can’t migrate into resonance? It seems like a resonant situation could be more stable and thus planets making their wait into resonance over time. I thought that often moons were captured and eventually move into resonant configurations.

[@rogerstone3068]

Definitely! There is some resonance in the solar system, yet they seem quite sure our planets have moved about. Some have resonance thrust upon them; why assume THESE ones were born resonant?

[@lepidoptera9337]

They don't "have to" form that way. Most systems might actually form in a chaotic state and then just lose most of the bodies. The argument is more likely one from statistical mechanics: if we represent the system in a multi-dimensional phase space, then the "keyhole" that the trajectory has to go through to end up in resonance if we start with non-resonance is probably extremely small. I don't know if one can prove that such a keyhole can't exist using energy and angular momentum conservation laws. In an case, no matter what happens something either has to be thrown out of the system or collide with the star, so a lot of the original matter in the accretion disk has been removed by the process either way.

[@BlinkinFirefly]

[@patrikhjorth3291]

Many years ago, when I still lived in my parents' house in the countryside, I was awake at night for some reason and looking out the window. This was in the middle of a very cold and snowy winter, but because of the distance to any large towns it was still pretty much pitch black outside. All of a sudden, there was a flash of light that I first thought was a lightning strike, except there was no thunder. Everything lit up, even brighter than daylight (or at least it seemed that way). I had _no idea_ what could have caused it, and my parents wouldn't believe me when I told them the next day. A couple of decades later, I witnessed a meteor flash across the sky, and that's when I understood that it must have been the same thing I saw back then.

The Amaterasu particle is fascinating. I guess that knowing its energy, you can't know its composition without knowing its speed and vice versa? I know that Apollo astronauts were subjected to some cosmic ray interactions (I recall Aldrin saying that if you closed your eyes you would occasionally see flashes, and I've seen an electron micrograph of a cone-shaped impact crater on a polycarbonate helmet) but I was wondering - if Amaterasu or OMG hit you, would anything happen?

[@stargazer7644]

This particle had a kinetic energy of nearly 40 J. That's about 1/3 of the energy from a .22 rifle bullet. It's about 30 times higher energy than a BB gun. 130 J can kill you. Yes you'd notice getting hit by it.

[@hubbsllc]

@@stargazer7644 Yeah, but a BB will actually start hitting whole molecules in my head the moment it reaches me; Amaterasu might go in a ways before having any matter interactions at all. It's apparent from the video that it didn't even make it all the way to the ground but still I'm wondering, would anything have happened to someone if they had been standing where that one patch of detectors was?

[@stargazer7644]

@@hubbsllcThe original particle doesn't make it very far into the atmosphere. The resulting blast of energetic debris that plows through the atmosphere to hit the ground would be spread out. You wouldn't notice the small portion of it hitting you. They like to say these events are rare, but what they mean is us detecting them with an instrument is rare. They happen all the time. Chances are good that one or more has hit you already in your lifetime.

When I was a kid my dad was a certified flight instructor. One year he took us in the plane to watch a mentor shower. The advantage of an airplane is you can get up above most of the atmosphere, and get above most of the moisture in the atmosphere and you can fly away from most of the lights on the ground and get an extremely clear view of the sky. Worth it if you can get access to an airplane.

That works as long as you stay relatively low in altitude. I always thought a nighttime commercial airliner flight would be ideal for stargazing out the window, but alas I was disappointed. At the 8,000 foot cabin altitude of a modern airliner your body starts to become oxygen deprived, and one of the first things to be affected by altitude is your night vision. You can't see many stars out the window even if you completely block out the cabin lights and become dark adapted. That's why astonomers are taught to hyperventilate and use averted vision to see faint objects at the telescope.

I erased weeks of mindless history in KZbin in an effort to keep only meaningful content. My hope was this would adjust my personal KZbin algorithms. It worked apparently what was left was beautiful ginger and intense science of energy flow.. I can’t imagine having missed Dr. Becky but I did. Until now. Kudos to the algorithm. Like wow. Beautiful energetic and space news. A lovely teacher with awesome graphics. I am hypnotized. I liked your song. It should be the theme song for the channel. Truly nice work. Ben Davidson is going to have to step up his game to keep his spot in my morning news. Thank you for sharing with us Doc!

When I was a kid there were these tv PSAs called Schoolhouse Rock and I somehow managed to memorize the lyrics of most of them. Whenever I click on a Dr. Becky video there's one in particular that starts playing in my head and doesn't stop until I replace it with another song. Interplanet Janet. I figure if I have to have this song in my head then so should anyone else who's ever heard it so here's the lyrics; They say our solar system is centered 'round the sun, Nine planets, large and small, parading by. But somewhere out in space, There's another shining face That you might see some night up in the sky. Interplanet Janet, she's a galaxy girl, A solar system Ms. from a future world, She travels like a rocket with her comet team And there's never been a planet Janet hasn't seen, No, there's never been a planet Janet hasn't seen. She's been to the Sun, it's a lot of fun, It's a hot-spot, It's a gas! Hydrogen and helium in a big, bright, glowing mass. It's a star, it's a star! So Janet got an autograph! Mercury was near the Sun so Janet stopped by, But the mercury on Mercury was much too high, so Janet split for Venus but on Venus she found She couldn't see a thing for all the clouds around. Earth looked exciting, kind of green and inviting, So Janet thought she'd give it a go. But the creatures on that planet looked so very weird to Janet, She didn't even dare to say hello. It's a bird, it's a plane! Why, it must be a UFO, but it was: Interplanet Janet, she's a galaxy girl, A solar system Ms. from a future world, She travels like a rocket with her comet team And there's never been a planet Janet hasn't seen, No, there's never been a planet Janet hasn't seen. Mars is red and Jupiter's big And Saturn shows off its rings. Uranus is built on a funny tilt And Neptune is its twin, And Pluto, little Pluto, is the farthest planet from our Sun. They say our solar system is not alone in space. The Universe has endless mystery. Some future astronaut May find out that what he'd thought Was a shooting star instead turned out to be... Interplanet Janet, she's a galaxy girl, A solar system Ms. from a future world, She travels like a rocket with her comet team And there's never been a planet Janet hasn't seen, No, there's never been a planet Janet hasn't seen.
