Galaxies in sentence

234 examples of Galaxies in a sentence

In this Hubble image, we see two galaxies.
Galaxies form, and generations of stars form in those galaxies, and around one star, at least one star, is a habitable planet.
I want her to look at the world through the underside of a glass-bottom boat, to look through a microscope at the galaxies that exist on the pinpoint of a human mind, because that's the way my mom taught me.
There are approximately a hundred billion galaxies in the observable universe.
I've often wondered, what is the evolutionary pressure that made our ancestors in the Veldt adapt and evolve to really enjoy pictures of galaxies when they didn't have any.
If you looked at one of these galaxies and measured its velocity, it would be moving away from you.
What you have to think about is we have a universe with a hundred billion galaxies, a hundred billion stars each.
Individual galaxies are speeding away from us faster and faster so we say the universe is accelerating.
It is a perpetual impulse that pushes galaxies apart from each other.
Occasionally, you will make a planet or a star or a galaxy or a hundred billion galaxies.
Even if you left our galaxy out, you would not get a hundred billion other galaxies.
We can see predictions of galaxies forming, of galaxies colliding into each other, of new solar systems.
How many galaxies are we losing per second?
And if we are interested, for example, in the fact that anti-gravity is pulling galaxies away from the Earth, why should we not be interested in what is going on inside of human beings?
They learn to annotate the images, and within a couple of minutes, they're up and running, and they're making really useful categorizations and classifications of these galaxies.
Now, it's easy to understand why Galaxy Zoo would be an easy sell for people to be involved with: it involves pretty pictures; galaxies are, generally speaking, pretty attractive.
There are maybe 100 billion galaxies detectable by our telescopes.
I mean, first of all, the 100 billion galaxies within range of our telescopes are probably a minuscule fraction of the total.
The vast majority of the galaxies are separating from us so fast that light from them may never reach us.
Still, our physical reality here on Earth is intimately connected to those distant, invisible galaxies.
And today, after briefly describing what they found, I'm going to tell you about a highly controversial framework for explaining their discovery, namely the possibility that way beyond the Earth, the Milky Way and other distant galaxies, we may find that our universe is not the only universe, but is instead part of a vast complex of universes that we call the multiverse.
Okay, part one starts back in 1929 when the great astronomer Edwin Hubble realized that the distant galaxies were all rushing away from us, establishing that space itself is stretching, it's expanding.
And they did this by painstaking observations of numerous distant galaxies, allowing them to chart how the expansion rate has changed over time.
What force is driving all galaxies to rush away from every other at an ever-quickening speed?
Because those universes that have much more dark energy than ours, whenever matter tries to clump into galaxies, the repulsive push of the dark energy is so strong that it blows the clump apart and galaxies don't form.
And in those universes that have much less dark energy, well they collapse back on themselves so quickly that, again, galaxies don't form.
And without galaxies, there are no stars, no planets and no chance for our form of life to exist in those other universes.
You see, we learned that our universe is not static, that space is expanding, that that expansion is speeding up and that there might be other universes all by carefully examining faint pinpoints of starlight coming to us from distant galaxies.
The light those galaxies emit, even traveling at the fastest speed, the speed of light, will not be able to overcome the ever-widening gulf between us.
Now maybe those future astronomers will have records handed down from an earlier era, like ours, attesting to an expanding cosmos teeming with galaxies.
