Interacting Galaxies Galore: Hubble's Universe Unfiltered

Показать описание

Hubble celebrated its 18th anniversary in 2008 by releasing a huge image gallery of interacting galaxies. Such galaxies pass close enough to each other that their mutual gravity can stretch and distort their shapes. Eventually, interacting galaxies merge together to form a single larger galaxy. However, since these interactions can take billions of years, how do we study them?

4:00 i really enjoyed his break down of the galactic distances from each other

I want to live in a world where this type of video is watched a lot more than 22k times in 10 years. What is wrong with people?

If theres so much space inbetwixt the stars when galaxies collide, how do new stars form when theres obviously not that much hydrogen helium etc?

I wonder if the tidal tails stay flung out in space or come back to the galaxies.

I think these videos, or this channel, are about the best ive seen.
All the others have too big too loud epic music. The talk alot of trash they know nothing about.
I like your videos. Thanks

super cool! i will feature this and all your future videos in my site. You speak slow and clear, easy for all to understand, and you present extremely interesting things! Thanks!

I had the understanding that there's a higher density of stars near the bulge and in nebulae; Also a higher density of galaxies in filaments shaped by dark mater/energy.

The distances he's talking abt are beyond my grasp, simply unimaginalbe. Luckily I can understand almost every single word of what he says. He speaks very, very distinctly, and not too fast, as for American guy! That' why I'm very fond of listrning to his super interesting lectures.

Nice explanation,
Is pretty interesting that the stars between them are farther in scale than an electron from the nucleus of an hydrogen atom.

We will be able to reach the nearest star to our sun, well maybe (if we don't annihilate ourselves first), but we will really need to make a Hyperspace jump to cross those distances fast.

Dammit, people, why don't you fix the asynchronous audio?

something going on with the bit rate. hmmm.

Its like galaxies are mating and giving birth to newborn stars, and the planets are born and then life is created. that would make the Milkyway our great grandpa.
