Which came first, the quasar or the galaxy?

Gravitational lensing works like this: When a large nearby object like a galaxy blocks a distant object, such as another galaxy, the light can detour around the blockage.

On the left, marked by red gas and dust clouds, is irregular galaxy M82.

"I estimate that there may be about two million such systems in our galaxy," he said.

In addition, last year other astronomers reported a steep metallicity gradient in an even farther galaxy, but that galaxy is not a spiral, so its relevance to the Milky Way is less clear.

Pulling himself together, he asked, rather shyly, "What is it you wish to know about my galaxy?"

Now the galaxy is full of gas and dust, which could hide a distant supernova optically, but the remnant would still produce detectable radio waves and X-rays.

Scientists were checking out a quasar, an incredibly distant, incredibly bright object. This quasar was the only one without a known host galaxy.

Most galaxies in our universe are bound together into clusters that dot the cosmic landscape like urban sprawls, usually centred around one old, monstrous galaxy containing a massive black hole.

The telescopes sift through the background cosmic radiation to find spots where it has been slightly perturbed as it passes through extremely hot gas, a hallmark characteristic of galaxy clusters.

Note the large" oval" of the galaxy, with the name" Andromeda Galaxy" below it.

We all know what a galaxy is, right?

"This galaxy is just beautiful," says Yuan. "Normally, galaxies at that redshift appear as blobs."

Astronomers have seen "Einstein rings", formed when light from a distant galaxy is bent by the presence of a nearer massive object, usually another galaxy, that lies directly in its path to Earth.

And then you just look around the little galaxy there, like the little ball of light that's blinking.

The galaxy is visible to the naked eye on moonless nights as a smudge of light and is the most distant object visible without a telescope.

That means when the two stars finally get around to merging, they could be far away from the galaxy of their birth — good news, as it happens, for optical confirmation.

Evidence may be in our neighbouring galaxy.

It is a galaxy of knowledge and information.

Imagine our galaxy as a red grape in the orange jelly of the universe.

Currently, the Milky Way is approaching the nearby Andromeda galaxy at a rate of 100 miles per second.

This galaxy was gobbled up by the Milky Way between six and nine billion years ago in an act of intergalactic cannibalism.

So when a quasar goes dormant, what's left are the things we associate with a normal galaxy — stars and gas swirling around a central and hidden pit of matter.

Since these powerful blasts of material significantly affect the surrounding galaxy, and even galaxy cluster in some cases, this work fits into the larger picture.

The image reveals in unprecedented detail the current rapidrate of star birth in this famous "grand design" spiral galaxy.

Between the ACTS she studied the galaxy of matinee attendants in front rows and boxes, and conceived a new idea of the possibilities of new York.

Not all parts of a galaxy are suited to life.

A giant black hole spouting energy from inside a galaxy is acting like a cosmic magnifying glass, giving astronomers a clear view of an even more distant galaxy behind it.

Our galaxy is on a collision course with the Andromeda galaxy.

Perhaps you would like to see the clerk who is specially concerned with the galaxy in question?

As you can see, the galaxy has more than one nucleus!

Because of the mammoth mass of our galaxy, this twisting should have an impact on space-time that is more than a million times stronger than that of Earth's spin, Hadley found.

That may explain why some quasars are surrounded by galaxies: the galaxy didn't form the quasar; rather the quasar pulled in the galaxy.
