quasar
quasi stellar object

The nature knows of no such thing as a quasar.

They say it is from a quasar some 12 billion light years away.

Why the hell would I know what a quasar is, though?

This is thought to be the driving force behind many quasars.

This is in much better agreement with the quasar data.

The light of the quasar does not travel in a straight line to earth.

Some 10 percent of the known quasars fall into this category.

The quasar releases the light more than 12 billion years ago.

It turned out that the quasars were billions of light- years away.

Around 12 billion years ago, he suggested, the quasars rapidly began to turn on.

Sources from the rest of the sky are mostly quasars.

Most quasars have been observed with red shifts of less than 3.

This activity happened before light left the quasar and began its long journey to Earth.

The two most distant quasars known have red shifts of 4.4 and 4.43.

These investigations could solve one major problem in quasar research.

These may take the form of two quasars in the same galaxy cluster.

At least 50 of these objects turned out to be quasars (which had not yet been discovered in 1961).

This is 100 million years earlier than light from the most distant previously known quasar.

These are thought to represent the earliest type of quasar.

Is this the first water vapor cloud found around a Quasar?

Now that we know what the quasars are, everyone seems to like the steady state hypothesis.

So dead quasars should be hiding in many nearby galaxies.

Many are convinced that quasars love company: they come in clusters and small groups.

Most quasars are much too distant to be observed in such detail.

The most distant quasar, discovered recently, has a red shift of 4.43.
