Energy source that may be 2 trillion times as bright as the sun

Usage examples of quasar.

June 1968 Analog that suggested the quasars are actually interstellar spacecraft within our own galaxy.

When the ritual of obstructionism to obtain the spectra of the BSOs ensued, Margaret Burbridge, a Briton with over fifty years of observational experience, bypassed the regular channels to make the measurement herself using the relatively small 3-meter reflector telescope on Mount Hamilton outside San Jose in California, and confirmed them to be quasars.

Variable stars, pulsars, spinars and quasars within the galaxy and out of it had each their effects upon the subfoundation of space through which the starship moved.

Thus it was in 1963 that Hoyle and William Fowler, astrophysicist from CalTech, proposed that the quasars might be supermassive objects relatively close to our own galaxy.

This opaque object was classified as a nonstandard quasar, as if there were such a thing as a standard quasar.

Incidentally, the Seyfert galaxies resemble the quasars in many respects, including the fact that they both tend to show sizable variations in light and radio output.

Arp found their association with quasar pairs to be so strong that it could almost be said to be a predictable attribute of Seyfert galaxies.

So the high redshift, quasarlike Seyfert ejected from the low redshift spiral was itself ejecting a pair of yet-higher-redshift sources, which turned out to be quasars.

Arp found that on charts showing quasar positions, pairing the quasars by redshift almost always leads to finding a cataloged Seyfert close to the center point between them.

She also removed the obvious quasars and Seyfert galaxies that masqueraded as brown dwarfs in her survey.

Variable stars, pulsars, spinars and quasars within the galaxy and out of it had each their effects upon the subfoundation of space through which the starship moved.

He visited Earth and met the australopithecines, he helped chart gas clouds and quasars, he ferried crews to outposts and construction projects.

Pulsars and quasars, both brilliant beacons glimpsed across the cosmos, had proved to be powered by small specks of compressed mass, resolved only decades after their emissions made them obvious.

There were clusters of freckles on her forearms and wrists, an entire Milky Way spreading across her forehead, even a few sputtering quasars flung into the wormholes of her ears.

They had cobbled together ideas from the study of pulsars and quasars and their story fit together reasonably well.
