Sentences with phrase «distant bright object»

Not exact matches

Put another way, those distant objects would be nearer, and therefore brighter, than you would naively expect if you simply extrapolated back from the way the universe is expanding closer to home.

These initial observations suggested that the apparently faint object was in fact both extremely bright and extremely distant.

The Compton Gamma Ray Observatory (CGRO), designed to detect gamma rays from distant astrophysical objects such as neutron stars and supernova remnants, had also begun recording bright, millisecond - long bursts of gamma rays coming not from outer space but from Earth below.

Astronomers studying distant objects call these stars «foreground stars» and they are often not very happy about them, as their bright light is contaminating the faint light from the more distant and interesting objects they actually want to study.

They are the locations of bright stars and other nearby objects that get in the way of the observations of more distant galaxies and are hence masked out in these maps as no weak - lensing signal can be measured in these areas.

The first clue that supermassive black holes exist was the discovery several decades ago of quasars — extremely bright objects in the centres of distant galaxies.

Added Bram Venemans of the Max Planck Institute for Astronomy in Germany: «Quasars are among the brightest and most - distant known celestial objects and are crucial to understanding the early universe.»

Quasars are among the brightest and most - distant known celestial objects and are crucial to understanding the early Universe, added Bram Venemans of the Max Planck Institute for Astronomy in Germany.

Scientists were checking out a quasar, an incredibly distant, incredibly bright object.

Quasars, discovered in 1963, are extremely distant massive black holes (MBHs) whose gravity pulls in immense amounts of nearby matter.24 The potential energy of all that infalling matter is converted to bright radiation, making quasars the most luminous stable objects in the universe.

Quasars are extremely bright, distant objects that are fueled by otherwise undetectable black holes.

The speeds seen in the quasars indicated that they were the most distant objects yet found, and, because they appear bright even at those great distances, must be extremely energetic.

A new analysis of galaxy colors, however, indicates that the farthest objects in the deep fields must be extremely intense, unexpectedly bright knots of blue - white, hot newborn stars embedded in primordial proto - galaxies that are too faint to be seen even by Hubble's far vision — as if only the lights on a distant Christmas tree were seen and so one must infer the presence of the whole tree (more discussion at: STScI; and Lanzetta et al, 2002).

Astronomers spotted the black hole, the most distant ever found, sitting inside a bright object so far away that the light had been traveling for 13 billion years before reaching Earth.
