Astronomers Precisely Measure a Black Hole's Accretion Disk
Actively feeding supermassive black holes are known as quasars, and they can outshine all the stars of their host galaxy. Part of their brightness comes from the accretion disk surrounding the black hole, but they're hard to image directly because quasars are so far away. New data from one of the world's largest telescopes has managed this feat, detecting near-infrared emission lines that mark significant regions in the accretion disk in a quasar.

#JWST spots what could be a #quasar from the #earlyUniverse -- The object’s deep red colour suggests it existed when the Universe was less than 700 million years old.

"Astronomers observe the very early Universe running in slow motion
Using cosmic clocks known as 'quasars', a team of astronomers perceive the early Universe running much slower than the present day."

Grundwasserentnahme verschiebt Erdachse jedes Jahr um mehrere Zentimeter
Die stetige Verschiebung der Erdachse verrät, wie viel Grundwasser die Menschheit jährlich entnimmt und in die Ozeane leitet. Es geht um gigantische Mengen.

860 Million-Year-Old #Quasar Had Already Amassed 1.4 Billion Times the Mass of the #Sun

#Astronomers using the #JamesWebbSpaceTelescope have discovered a thread-like arrangement of 10 #galaxies that existed just 830 million years after the Big Bang. The 3 million light-year-long structure is anchored by a luminous #quasar—a galaxy with an active, #supermassiveblackhole at its core. The team believes the filament will eventually evolve into a massive #clusterofgalaxies, much like the well-known #ComaCluster in the #nearbyuniverse.
