The JWST Makes Some Headway Understanding Little Red Dots November 19, 2025
Researchers using the NASA/ESA/CSA James Webb Space Telescope have confirmed an actively growing supermassive black hole within a galaxy just 570 million years after the Big Bang. Part of a class of small, very distant galaxies that have mystified astronomers, CANUCS-LRD-z8.6 represents a vital piece of this puzzle that challenges existing theories about the formation […]
We've Long Thought The Surface Area Of A Black Hole Can't Decrease. Now We Have Data To Back It Up. November 19, 2025
Observations of a merging black hole further supports the Area Theorem of black hole thermodynamics, which states that the event horizon of a black hole produced by two merging black holes must have a surface area no less than the areas of the original two.
Hunting For "Wnadering" Black Holes In Dwarf Galaxies November 19, 2025
Tracking down black holes at the center of dwarf galaxies has proven difficult. In part that is because they have a tendency to “wander” and are not located at the galaxy’s center. There are plenty of galaxies that might contain such a black hole, but so far we’ve had insufficient data to confirm their existence. […]

To be fair, all scientific models are in some sense wrong
The Andromeda Galaxy Quenches Its Satellite Galaxies Long Before They Fall In November 18, 2025
Galaxies grow massive through mergers with other galaxies. Massive galaxies like the Milky Way and Andromeda not only merge with other large galaxies, they also absorb their much smaller satellite dwarf galaxies. But these smaller galaxies can become quenched long before they're absorbed, and new research examines this process at Andromeda (M31).
