Stephen Hawking

In less than a hundred years, we have found a new way to think of ourselves. From sitting at the center of the universe, we now find ourselves orbiting an average-sized sun, which is just one of millions of stars in our own Milky Way galaxy.

English Physicist

Shannon Walker

We have stars, planets and galaxies in space. There's lots of nothingness out there, but it's really not. There's gas, dust and other bits of matter floating around emptier' areas of the universe, but you can't see it very easily.

Jim Peebles

There must be enormous numbers of planets around the stars in the many galaxies in our observable universe. We may be sure that wonderful things are happening on these planets that the human race never will observe.

Canadian Scientist

Kelly Marie Tran

Even though 'Star Wars' takes place in another galaxy, a lot of the themes and things that characters deal with in terms of lessons that they're learning are things that are completely relatable to real life.

American Actress

Leonardo DiCaprio

I love science fiction, but I have a hard time feeling for characters in a galaxy far away. Choosing movies is the one thing in my life where there's no compromising.

American Actor

John Travolta

I have to believe there's some other life force out there. I don't know in what form. But we can't have all these galaxies and universes without something going on.

Robert Lanza

For example, if the big bang had been one-part-in-a billion more powerful, it would have rushed out too fast for the galaxies to form and for life to begin.

American Scientist

Priyamvada Natarajan

Finding the first seed black holes could help reveal how the relation between black holes and their host galaxies evolved over time.

Indian Scientist

Jonathan Frakes

I've always thought that we, as human beings, would be naive and arrogant to pretend that we're the only life form in the galaxy.

Martin Rees

There are at least as many galaxies in our observable universe as there are stars in our galaxy.

British Scientist

Used in scientific contexts to describe vast systems of stars and celestial bodies.

Astronomy Term

A galaxy is much larger than a constellation; it contains many constellations within it.

Not a Constellation

Gravity holds a galaxy together, making it a united system, not a random cluster.

Gravity's Role

Often used metaphorically to describe an extensive, impressive collection or group.

Metaphorical Usage

When used metaphorically, 'star' means people of exceptional talent, not celestial bodies.

Not Literal Stars

Using 'galaxy' can exaggerate qualities to emphasize a point in informal contexts.

Exaggeration for Effect

In the UK, 'Galaxy' refers to a popular smooth and creamy chocolate brand.

British Candy

When discussing candy, 'galaxy' loses its astronomical meaning; context matters.

Not Astronomical

The word's confectionery meaning might not be understood outside the UK.

Specific to UK

 That's incredible when we think about how vast the universe is. Why would we expect it to be the same across such huge distances? On the scale of a galaxy, let alone the universe, we're smaller than we can readily comprehend, but we do have the capacity to wonder, to question, to explore,

Questions No One Knows...

 Astrophysicists don't just see the billions of stars among the billions of galaxies in the universe. They hear, feel and sense them through many channels, each revealing a different story. But it all begins with light, the kind we can see and the kind we can't.

How do we study the...

 And those smudgy galaxies? They're millions of light years away. It has taken millions of years for that light to reach us. So the universe itself is in some sense an inbuilt time machine. The further we can look back, the younger the universe we are probing.

Light seconds, light...

 Useful as the universe's most massive laboratories. And as laboratories, to describe galaxy clusters is to describe the experiments that you can do with them. And I think there are four major types, and the first type that I want to describe
