Scientists create the largest chart of active supermassive black holes
Supermassive black holes are concentrated masses in the centers of galaxies, with the 3D map revealing 1.3 million of them.
The map, created with data from the Gaia spacecraft, shows quasars - active supermassive black holes feeding on material, emitting bright radiation. [ more ]
'Overmassive' Black Holes Dominated Early Galaxies, Study Finds
Early supermassive black holes in ancient galaxies are smaller than those in our nearby universe but appear too big compared to the mass of stars in their host galaxies.
These early black holes were likely spawned by collapsing gas clouds and were more massive than their galaxies, but galaxies gained stellar mass over time. [ more ]

Hubble Snaps Alarming Pic of Two Galaxies Crashing Into Each Other
NASA's Hubble Space Telescope has captured an image of two massive galaxies colliding with each other.
This collision, known as 'Arp 122,' could eventually form a singular structure of dust, gas, and dark matter in hundreds of millions of years. [ more ]
Simulations reveal the hidden behaviors of dark matter
A new theory suggests that colder dark matter moved at slow velocities while standard matter streamed past it at supersonic speeds, leading to the formation of small, bright galaxies earlier than previously thought.
The presence of small, bright galaxies in the early universe would confirm the cold dark matter model, as only the velocity between two types of matter can produce this type of galaxy. [ more ]

Messy Plasma Streams Explain Supermassive Black Holes Influence On Galaxies
Supermassive black holes have different feeding habits, but emit the same radiation, which could help explain their influence on galaxies.
A new study found that black holes with different appetites glow in the same way, regardless of the amount and manner of matter falling into them. [ more ]

See the second farthest galaxy ever discovered in new NASA image
The James Webb Space Telescope (JWST) has discovered two new galaxies within the Pandora's Cluster, one of which is now the second-farthest galaxy seen by human eyes.
The newly discovered galaxy, Z-13, was estimated to have emitted light when the universe was about 330 million years old, and it traveled for about 13.4 billion light years to reach the JWST.
The discovery of these galaxies provides valuable insights into the early universe and the formation and growth of galaxies during that time. [ more ]
