Quasare sind über weite Bereiche der elektromagnetischen Strahlung hell und haben charakteristische Spektren mit sehr breiten Emissionslinien, die in rascher Bewegung befindliches Gas anzeigen. Black holes Most massive Quasars.

Most Powerful Quasar Discovered These widths are due to Doppler shifts caused by the high speeds of the gas emitting the lines. The BBC has updated its cookie policy. Applying Hubble's law to these redshifts, it can be shown that they are between million [14] and Many astronomers believe that quasars are the most distant objects yet detected in the universe. The true nature of this object became apparent when astronomers discovered that the intense energy was being produced in a relatively small area.

What is a quasar - gemäß Mediengesetz:

Some scientists even believe that quasars are distant points in space where new matter may be entering our universe. As the matter spins faster and faster, it heats up. Many lines of evidence optical viewing of host galaxies, finding 'intervening' absorption lines, gravitational lensing now demonstrate that the quasar redshifts are due to the Hubble expansion, and quasars are in fact as powerful as first thought. Apple Podcasts Android RSS. The emission of large amounts of power from a small region requires a power source far more efficient than the nuclear fusion that powers stars. The quasar mystery Astronomers investigate quasars in the late s. Explicit use of et al. Ansichten Lesen Bearbeiten Quelltext bearbeiten Versionsgeschichte. Containing many unknown broad emission lines, the anomalous spectrum defied interpretation — a claim by John Bolton of a large redshift was not generally accepted. Sir Patrick Moore and his guest Dr Jaspar Wall explain what quasars are and how we know they exist. Gas and dust likely form a torus around the central black hole, with clouds of charged gas above and below. The most powerful quasars have luminosities exceeding 10 41 W , thousands of times greater than the luminosity of a large galaxy such as the Milky Way. That, in fact, several different kinds of objects: Another radio source, 3C , was predicted to undergo five occultations by the Moon. In 10 billion years werkstatt spiele so, when the Milky way collides with Andromeda, our supermassive black hole may roar to life as a quasar, consuming all this new material.

Why Are Planets Round? Ein Quasar besteht vermutlich aus einem Schwarzen Loch umgeben von einer Scheibe leuchtender Materie. The fastest pulsars can pulse at well over a hundred times a second.
