The Hubble Space Telescope has shown that dark matter is concentrated in the core of a nearby dwarf galaxy, a discovery that comes to the aid of the Standard Model of Earth. cosmology. This model basically predicts that dark matter is “cold,” but recent findings seem to indicate that the substance is “warm.” However, these … Read more
If you look up at the sky for a while during the summer, you’ll probably see a few “shooting stars” streaking across the sky. The best meteor show of the summer occurs in the second week of August during the annual Perseid meteor shower, which, peaking around the nights of August 11th and 12th, is … Read more

Enlarge / The Milky Way’s central black hole is in a very crowded environment. Supermassive black holes are voracious. Clumps of dust and gas are often disrupted by turbulence and radiation when they get pulled too close. So why are some of them orbiting the edge of the Milky Way’s own supermassive monster, Sgr A*? … Read more
Neutron stars are among the densest objects in the universe. The material inside them is so tightly compressed that scientists don’t yet know what shape it takes. The core of a neutron star may be a thick soup of quarks, or it may contain exotic particles that could not survive anywhere else in the universe. … Read more
The half-radius of the Milky Way compared to that of local disk galaxies. Credit: Nature Astronomy (2024). DOI file: 10.1038/s41550-024-02315-7 A small team of astronomers from the University of Yunnan, the University of Utah, New Mexico State University and the University of St. Andrews has developed a new model of the Milky Way based on … Read more
Scientists may have unlocked the secret of the still-beating hearts of the universe’s most extreme “dead stars,” but the explanation is twisted. The team thinks that an avalanche of quantum tornadoes is causing this ‘disturbance’ in the rotation of a class of neutron stars called pulsars. This happens when they become entangled with neighbouring stars, … Read more

Researchers have linked the periodic pulses of neutron stars to internal disturbances influenced by superfluid vortices. A new model suggests that these disturbances follow a power-law pattern observed in several natural phenomena. Credit: SciTechDaily.com A recent study has revealed the origin of the mysterious “heartbeats” observed in neutron stars, linking them to disturbances caused by … Read more
