What is a Quasar? The Brightest Object in the Universe — Atacama Stargazing

A quasar is an astronomical object that emits enormous amounts of energy across the entire electromagnetic spectrum, from radio waves to X-rays. Its name comes from the English acronym for "quasi-stellar radio source," because when they were discovered they looked like simple points of light in the sky.

Quasars are the result of the activity of supermassive black holes, with masses of millions or billions of times that of the Sun, located at the center of very distant galaxies. These black holes pull in the gas and dust around them, forming an accretion disk that heats up to extreme temperatures and shines with great intensity. In addition, the black hole's magnetic field generates two jets of particles that shoot out at speeds close to that of light in directions opposite to the disk. These jets are responsible for the emission of radio waves and other wavelengths.

Quasars are the most luminous and energetic objects in the known universe. They can outshine their entire host galaxy and be visible from enormous distances. In fact, the quasars we observe today show us how they were billions of years ago, when the universe was younger and there was more matter available to feed the black holes. Quasars are believed to be a transient phase in the evolution of galaxies, lasting a few hundred million years.

Quasars are fascinating objects that let us study extreme physics and cosmic history. Studying them requires the use of very powerful and sensitive telescopes, capable of picking up their faint signal amid the noise of the cosmic background. There is, however, a simpler and more pleasant way to get closer to these mysteries of the universe: visiting San Pedro de Atacama, the best place in the world to observe the night sky.
