Here's Why So Many Massive Galaxies in the Early Universe Stop Forming Stars

The early Universe is full of massive galaxies that stopped forming stars very early. They're called massive quenchers (MQ) and they're challenging to explain. New research shows that another type of galaxy, dusty star-forming galaxies (DSFGs) can explain why. It's all about mergers, starbursts, and AGN feedback.

Asteroid Dirt is "Fluffier" Than We Thought

The strength of gravity is different on every body in the solar system.

Astronomers Uncover Statistical Evidence for Recoiling Supermassive Black Holes

Galactic collisions are events of breathtaking proportions. The Supermassive Black Holes (SMBHs) at their centers plunge into a chaotic orbital dance that eventually coalesce into a single remnant. On their way to that point, they could eventually get “kicked” out of the center of their galaxy - and finding these “recoiling” black holes has been a challenge of cosmology for decades.

Flash-Melted Glass from Chang'e-5 Reveals a High Levels of Iron on the Moon

It might not seem like it, but the Moon is constantly being both sandblasted and baked. Its lack of a thick atmosphere allows micrometeorites to impact the surface at speed, and the solar wind isn’t held back either, baking the regolith with a constant flow of high-energy particles. These processes drive what is called “space weathering”, and it can drastically alter the physical and chemical properties of the lunar dirt over the course of billions of years.
