A state of matter last seen just after the Big Bang may exist inside neutron stars -- and scientists think they can prove it
By breaking down the problem into separate regions of varying gravitational strength and combining approximate solutions, researchers were able to derive a solution describing all the oscillatory modes of a neutron star's interior and how they are imprinted on the frequency of gravitational waves.

A mass stellar migration billions of years ago may have helped life get started on Earth
The discovery that the sun and many solar twins are of similar ages and distances from the galactic core suggests a mass migration of stars occurred outward from the center of the Milky Way, potentially impacting the habitability of the solar system.

Could the Milky Way galaxy's supermassive black hole actually be a clump of dark matter?
The theory proposes that the dense core of fermionic dark matter could cast a shadow similar to the one seen in the Event Horizon Telescope image of Sagittarius A*, challenging the traditional view of a supermassive black hole in the center of our galaxy.

Pulsary odhalily obří mrak temné hmoty v blízkosti Sluneční soustavy. Jeho gravitace mění dráhy neutronových hvězd
Tento objev může zásadně pomoci při hledání podstaty neznámé temné hmoty
Vědci poprvé detekovali silné indicie naznačující přítomnost obrovského mraku temné hmoty, který se nachází zhruba 3260 světelných let (~1 kiloparsek) od Slunce.

This supermassive black hole jet is more powerful than the Death Star's laser: 'Planets are going to be destroyed'
The jet, nicknamed "Jetty McJetface," is currently 50 times more luminous than when first detected in 2018, and its ongoing rise in energy output is attributed to the jet broadening and entering our line of sight as it decelerates, a phenomenon considered unprecedented in black hole activity.
