The Milky Way vs. Andromeda: When Galaxies Collide

Our sun is one of hundreds of billions of stars that make up the spiral disk of our Milky Way galaxy. In turn, our galaxy is one of a hundred billion more that we can observe in the universe.
Join Dr. Prichard as she delves into the discovery of these “island universes” and explains how many types of galaxies form.
Take a tour of our galaxy’s neighborhood, including an adventure into our prospects of interstellar travel. The exploration will reveal the ultimate fate of the Milky Way when it collides with our massive spiral neighbor, the Andromeda galaxy, in 4 billion years.
Host: Frank Summers, Space Telescope Science Institute

I enjoyed the lecture very much in the comfort of my recliner chair and a coffee.
Thanks fatimah
Amazing! I wish this lecture never ends and I keep learning more and more
A most interesting lecture that I have seen! Really enjoyed the speaker and what she had to say. Definite thumbs up.
Thank you Laura and Dr Frank. learning so much from you guys.
Thank you for sharing this very interesting lecture !
Terrific! Thanks
Really great lecture overall and I appreciate Dr. Prichard's time and efforts. Galactic astronomy is such a fascinating field, as is the history behind it. However, I wasn't really a fan of when she talked about aspects of cosmology being unlikeable or impossible to comprehend by humanity. To me, it all makes sense mathematically (otherwise it would not be the prevailing theory), and just because physics is unusual or "untidy" doesn't mean I dislike it. On the contrary, I think it makes it that much more amazing and wonderful and likeable. That's one of the reasons why I enjoy astronomy so much, because it lets me learn about unusual, extreme, and really cool physics that I can't experience here on Earth. When I'm told what I can and can't comprehend or even like, I feel very talked down to and it gets on my nerves.
A very informative lecture in a simplified form so that I could understand more about our earth and the stars around us ... though I need to watch again to better understand God's magical creation🌎💎many thanks
Seattle is here
If there is LIFE here, there is LIFE somewhere else. We are not a one off... We are evidence that Life exists. Other world's are saying the same thing... We don't have to look. Spend more money on cleaning up EARTH. 🌎💖🌏💖🌍
Thank you for the detailed explanation.
The invisible region the "halo"
seems to have already started
a collision.
l made the phenomenon Music🌌
I just hope that Humanity still has time for many more generations to come.
plz help me undrestand is hubble takespictures with colors or without. if pictures without colors (black and white) how we color them i mean based on what ?
They are not black and white, I’m fairly certain. There’s the visible light spectrum, ultraviolet spectrum and infrared that it can see. So, depending on what spectrum you’re using it can see different things. Visible light is very much colorful, however.

All Time it is Time. 😢.
Whatever it is , there is 0.00001% chance to milky way and andromeda galaxy collision 💥. Because, it is like expecting the collision of 2 paper boats which is floating in the Atlantic Ocean’s two edges.
Laura Prichard is amazing.
If the galaxies are moving away from each other rapidly why is Andromeda moving so rapidly towards our Milky Way?
Close enough to be gravitationally bound.

before going to the stars, we need to learn how to chase 1I/'Oumuamua. We need to learn how to use Nuclear, without the risk of catastrophic accidents, like this one: what if a 100_meter asteroid directly hits a reactor building! ( --> use advanced submarines for el.power-generation or land-based fusion). Slow down Chinese steel production (coal), use and recycle more Aluminium (for cars). Stop expanding the over-rated wind-energy euphoria. Side effects: reduction of atmospheric Coriolis, increased winds from the North to South, fewer Westerlies; increased direct transport of warm air masses to the pole and over Iceland's glaciers! Excessive wind-energy use is warming the North-Pole (Climate-calculating scientists will rub their eyes in disbelieve!)
Active atmospheric measures to cool the planet would become necessary in about 5E7 years! (Bill Gates' CaCO3-nanoparticle- project in July 2021 is way too early.)
Last, but not least, this planet's technical civilization needs long working machines: machines, that operate 4E3 years, 4000_y Let's start with clocks ( autonomous and maintenance-free ones), cars, and rugged and reliable spaceships!
At the world economic forum in Davos, the elites are discussing nonsense each year!
Laura youre research is I have no words. This is mind blowing research. I was doing this kind of research at a fragment just very tiny back in college. YOU MY FRIEND ARE CLOSE TO GODLINESS.
Laura comes from bacteria. You too?
if you generated from bacteria then why didn’t you generate your self something else like liveable in space. Or liveable in mars or in the sun.
"It was a dark and stormy night" was the opening for " A Wrinkle In Time,". Snoopy plaigerised it.
Great video! Maybe next time if its possible increase the size of your facecam?
The slides are more important.
Aliens probably have found us, but saw that we still have wars and pollution so they locked their doors and kept moving.
Just imagine shoveling all of the snow if we inhabited Neptune where these massive storms take place?!?!😁🙄
Obviously kidding!😁
I am Professor Cruz President of the "Flat earth society" this is all untrue, (CNN,MSNBC,ABC,CBS,NBC) agrees with me. I believe what they report, they love America. LOL
love her British voice .....
she is my kind of scientist ;)
I have to share this here. I haven't done so much research on the following topic it is something I heard from my maternal grand dad who was an avid reader. I'm not sure even what he said was true or not but he said and I quote " la tasabu ud dah'r " my grand dad said it is what he read from a book of Ibn e razi a Muslim philosopher in the 800's. My grand dad translated it to and I quote " zamaney ko bura mut Kao Kyun Ke zamana Khuda Hai. Google the translation. But what he was saying was that when nothing existed some time was passing by. Right. I cannot help but admit that this right time still existed. So the closest to GOD is I guess time. Noone created time. Some time was always there and passing by. Now I'm not saying that time is GOD but I'm a skeptic and a believer.
How will you answer this Laura? Would love to know anyone's opinion. I would rather have a one on one conversation than give out my email address. Thanks Laura YOURE GREAT.

Hello friends,my name is "Good Morn'n Sunshine"let your light shine!light the way!I'm a daydreamer and a night thinker!PARTY ON , so Al Gore is my idol
All these really intelligent people ; and a cult like psychiatry exists - not even questioned
lol do you have an inner meaning
Do you even know what the term psychiatry means?Or are you throwing words here and there to sound smart ?
@@d3p134 i looked up psychiatry definition . Wikipedia has a good page ; Merriam-Webster has a definition .
BUT - there is the reality of what psychiatrists are actually doing and NOT doing ; which I know about from over 30 years of my personal experience .
You just had to knock Hubble, If he was a women. you never would of said it
National Geographic some years ago that had a 2 page spread about Andromeda being the ultimate enemy of earth, since when Andromeda and Milky Way interpenetrate, earth might or might not survive.
Well, I got drawn into this vid because UA-cam titled the vid as bring about Andromeda and the Milky Way. However, 10 minutes in there is no sign of that topic coming any time soon, so I'm leaving.
A list of topics and about how long each topic was going to be would have helped.
I took university astronomy, but... nope. Not intetersted yet, so bye.
You lost me at Greta Thornburg
Bye bye, science-denier!
@@shadetreader I didn't know Greta Thornburg is a scientist.
Are you really quoting Greta Thunberg. Sorry checking out now.
Either you support science or you don't. Cherry-picking reality is how conservatives have made states like Texas and Florida into hellish covid hotspots.
@@shadetreader dude Greta Thunberg is not science.
Terrific, climate crap. Thank you but I’ll unsubscribe now.
