Matter at extreme conditions of very high temperature and pressure turns out to be remarkably simple and universal

Scientists at Queen Mary University of London have made two discoveries about the behaviour of ‘supercritical matter’ – matter at the critical point where the differences between liquids and gases seemingly disappear. Previously, while the behaviour of matter at reasonably low temperature and pressure was well understood, the picture of matter at high temperature and …

Fast Radio Bursts Piercing Gaseous Halos Around Galaxies

Powerful Radio Pulses Originating Deep in the Cosmos Probe Hidden Matter Around Galaxies

This artist’s concept shows distant fast radio bursts piercing the gaseous halos around galaxies in the local universe. The radio bursts are depicted traveling from the distant cosmos, through the galactic halos, and finally reaching telescopes on Earth. The bumps seen in two of the lines represent the radio burst themselves as they travel toward …

Dwarf galaxies of Earth’s second closest galaxy cluster are free of dark matter halos

The standard model of cosmology suggests that a halo of dark matter particles surrounds most galaxies. However, this halo of dark matter is invisible, but its mass exerts a strong gravitational pull on galaxies in the vicinity. A new study by the University of Bonn (Germany) and the University of Saint Andrews (Scotland) challenges this …

Jupiter Missions Could Also Help Search for Dark Matter

Jupiter Missions Could Also Help Search for Dark Matter

In a recent study published in the Journal of High Energy Physics, two researchers from Brown University demonstrated how data from past missions to Jupiter can help scientists examine dark matter, one of the most mysterious phenomena in the universe. The reason past Jupiter missions were chosen is due to the extensive amount of data …

Physicists Finally Measure a Long Theorized Molecule Made From Light And Matter

Physicists Finally Measure a Long Theorized Molecule Made From Light And Matter

Physicists have just caught light acting the part of ‘glue’ between atoms, in a kind of loosely bonded molecule. “We have succeeded for the first time in polarizing several atoms together in a controlled way, creating a measurable attractive force between them,” says University of Innsbruck physicist Matthias Sonnleitner.   Atoms connect to form molecules in …

Dark matter from 12 billion years ago detected for the 1st time

Scientists have discovered dark matter around galaxies that existed about 12 billion years ago, the earliest detection yet of this mysterious substance that dominates the universe.  The findings, achieved by a collaboration led by researchers from Japan’s Nagoya University, suggest that dark matter in the early universe is less ‘clumpy’ than predicted by many current …

This Record-Breaking 'Black Widow' Pulsar Is The Most Massive Neutron Star Yet

This Record-Breaking ‘Black Widow’ Pulsar Is The Most Massive Neutron Star Yet

One of the most extreme stars in the Milky Way just got even more wack. Scientists have measured the mass of a neutron star named PSR J0952-0607, and found that it’s the most massive neutron star discovered yet, clocking in at a whopping 2.35 times the mass of the Sun.   If true, this is …
