Edwin Powell Hubble Quotes

I am undecided whether or not the Milky Way is but one of countless others all of which form an entire system. Perhaps the light from these infinitely distant galaxies is so faint that we cannot see them.

The question that I started off with was, I thought, very simple. It was just 'Is there a massive black hole at the center of the Milky Way?' But one of the things I love about science is that you always end up with new questions.

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

The Milky Way is nothing else but a mass of innumerable stars planted together in clusters.

It bears mentioning that the Milky Way is only one of 150 billion galaxies visible to our telescopes - and each of these will have its own complement of planets.

Seeing outward is equivalent to looking backward in time because the telescope's mirror is capturing primeval light... galaxies that existed before our time.

We must believe then, that as from hence we see Saturn and Jupiter; if we were in either of the Two, we should discover a great many Worlds which we perceive not; and that the Universe extends so in infinitum.

The universe is a big place, perhaps the biggest.

Philosophically, the universe has really never made things in ones. The Earth is special and everything else is different? No, we've got seven other planets. The sun? No, the sun is one of those dots in the night sky. The Milky Way? No, it's one of a hundred billion galaxies. And the universe - maybe it's countless other universes.

The universe is a great mystery.

There's a large cluster of stars that are orbiting the center of our galaxy. And by measuring the motion of stars, and in particular, their orbits, we can figure out whether or not there's a central black hole.

If you want to see a black hole tonight, tonight just look in the direction of Sagittarius, the constellation. That's the center of the Milky Way Galaxy and there's a raging black hole at the very center of that constellation that holds the galaxy together.

The earth, that is sufficient, I do not want the constellations any nearer, I know they are very well where they are, I know they suffice for those who belong to them.

Maybe dark matter is denser than we usually assume, kind of like the Milky Way plane.

We've seen black holes, which is already wonderful. We also expect to see the merger of neutron stars, and that was a thing that actually gave this field a certain credibility when it was discovered that there were pairs of neutron stars in our galaxy, and people stopped laughing at us when that was found out.

This is the first real evidence that we've seen now of high gravitational field strengths: monstrous things like stars moving at the velocity of light, smashing into each other, and making the geometry of space-time turn into some sort of washing machine.

Venus and Mars are our next of kin: they are the two most Earth-like planets that we know about. They're the only two other very Earth-like planets in our solar system, meaning they orbit close to the sun; they have rocky surfaces and thin atmospheres.

The Kecks will allow us, like no other telescope in history, to view the evolving universe that gave us birth.

Every field of astrophysics - whether it's our local neighborhood of planets, nearby stars and their attendant planets, galaxies, clusters of galaxies, out to the edge of the universe - every field has questions that are awaiting the power of Hubble.

It's quite likely that planets and solar systems like ours could be forming in other galaxies in great numbers.

Black holes are enigmatic astronomical objects, areas where the gravity is so immense that it has warped spacetime so that not even light can escape.

Stars are extremely far apart. We cannot imagine any way currently available to get to the nearest one, besides the sun.

Data suggest that central black holes might play an important role in adjusting how many stars form in the galaxies they inhabit. For one thing, the energy produced when matter falls into the black hole may heat up the surrounding gas at the center of the galaxy, thus preventing cooling and halting star formation.

The predominant theory of the origin of the universe is the Big Bang.

We live inside our universe and cannot get a bird's-eye view of it from outside. And we cannot even see all of our universe. Distant parts of it are expanding away from us so fast that they are invisible; they go faster than the speed of light. Having bigger telescopes to see fainter stars will not help us here: invisible is truly invisible.
