Half the matter in the universe was missing – we found it hiding in the cosmos
Half the matter in the universe was missing – we found it hiding in the cosmos Cosmologists had only been able to find half the matter that should exist in the universe. With the discovery of a new astronomical phenomenon and new telescopes, researchers just found the rest.

A long-lost type of dark matter may resolve the biggest disagreement in physics
“We Exist Within a Colossal Sphere” –The Void that Harbors the Milky Way (Weekend Feature) | The Daily Galaxy Our Milky Way Galaxy exists in void –one of the vast holes of the “Swiss-cheese” structure of the cosmos– with a radius measuring roughly 2 billion light years in diameter –the largest void known…

The Universe may not look the same in all directions after all – Astronomy Now
The Universe may not look the same in all directions after all – Astronomy Now One of the core assumptions all professional and amateur astronomers learn when first entering the field is that at large scales, the universe appears the same in all directions, that is, it’s isotropic. A paper accepted for publication in…

Mysterious radio bursts from a nearby spiral galaxy
Mysterious radio bursts from a nearby spiral galaxy Fast radio flashes still pose something of an enigma to astronomers. Although they only emit for milliseconds at a time, hundreds have been observed in the sky. Only four such Fast Radio Bursts (FRB) have been precisely located so far. Now astronomer have traced the source of…

A Crisis in Cosmology – W. M. Keck Observatory
A Crisis in Cosmology – W. M. Keck Observatory Maunakea, Hawaii – A group of astronomers led by University of California, Davis has obtained new data that suggest the universe is expanding more rapidly than previously thought. The study comes on the heels of a hot debate over just how fast the universe is ballooning; measurements…

Astrophysicists Link Brightening of Pulsar Wind Nebula to Pulsar Spin-down Rate Transition—Chinese Academy of Sciences
Astrophysicists Link Brightening of Pulsar Wind Nebula to Pulsar Spin-down Rate Transition—Chinese Academy of Sciences Astrophysicists have discovered that the pulsar wind nebula (PWN) surrounding the famous pulsar B0540-69 brightened gradually after the pulsar experienced a sudden spin-down rate transition (SRT). This discovery, made by a group of astrophysicists led by GE Mingyu and LU…

Black Hole Holograms
Black Hole Holograms A research team from Osaka University, Nihon University and Chuo University has proposed a novel theoretical framework whose experiment could be performed in a laboratory to better understand the physics of black holes. This project can shed light on the fundamental laws that govern the cosmos on both unimaginably small and vastly…

The first AI capable of simulating the universe works so well it’s scary
The first AI capable of simulating the universe works so well it’s scary A team of researchers recently pioneered the world’s first AI universe simulator. It’s fast; it’s accurate; and its creators are baffled by its ability to understand things about the cosmos that it shouldn’t. Scientists have used computer simulations to try and digitally…
