![]() Some quasars seen at high resolution exhibit a “fuzz” of light. ![]() Observational clues from the Hubble Space Telescope and other instruments able to observe the far reaches of the cosmos are giving astronomers leads. Slowly, the question of what quasars are morphed into how quasars formed. We’re excited to announce Astronomy magazine’s new Space and Beyond subscription box – a quarterly adventure, curated with an astronomy-themed collection in every box. Perhaps these diverse objects, astronomers thought, were similar creatures viewed from different angles.īringing the universe to your door. Quasars became part of a spectrum of energetic galaxies called active galactic nuclei (AGN), which also includes Seyfert galaxies, BL Lacertae objects, and radio galaxies. One byproduct of the infalling matter is a high-energy jet erupting from near the black hole and hurling material into space. In the 1990s, scientists increasingly viewed quasars as young galactic cores where gas, dust, and stars fed a central black hole. By the 1980s, quasars’ prodigious X-ray and radio emissions led most astronomers to believe these objects contain black holes in their centers. ![]()
