Australian scientists from the University of Sydney and Australia’s national science agency, CSIRO, have detected what is likely a neutron star spinning slower than any other ever measured. No other radio-emitting neutron star, out of the more than 3,000 discovered so far, has been discovered rotating so slowly. The results are published in Nature Astronomy. Lead author Dr. … Read more
Quasars, short for “quasi-stellar radio sources,” are among the most enigmatic and fascinating objects in the cosmos. They are incredibly bright and energetic, emitting radiation across the entire electromagnetic spectrum, from radio waves to X-rays and gamma rays. Quasars are powered by the accretion of material onto supermassive black holes at the centers of galaxies, … Read more
The dance of galaxies in the cosmic web is a mesmerizing spectacle of cosmic structure and evolution, revealing the intricate interplay of gravity, dark matter, and cosmic forces shaping the large-scale distribution of galaxies in the universe. The cosmic web is a vast network of filaments, voids, and clusters that connect galaxies across cosmic distances, … Read more
Pulsars are cosmic lighthouses, beacons of intense radiation and magnetic fields that emit beams of light and other forms of electromagnetic radiation as they rotate rapidly. These exotic objects, often referred to as neutron stars, are the remnants of massive stars that have undergone supernova explosions. Pulsars were first discovered in 1967 by astrophysicist Jocelyn … Read more
Astronomers have discovered one of the most powerful eruptions from a black hole ever recorded. This mega-explosion billions of years ago may help explain the formation of a striking pattern of star clusters around two massive galaxies, resembling beads on a string. This discovery was made in the system known as SDSS J1531+3414 (SDSS J1531 … Read more
