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.

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 Astronomy and Astrophysics suggests that may not be the case.

An international team of researchers using NASA’s Chandra X-ray Observatory, the European Space Agency’s XMM-Newton and other data archives studied the X-ray luminosity of 842 galaxy clusters.

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 newly discovered FRB to a nearby spiral galaxy similar to our own Milky Way, a galaxy half a billion light-years from Earth, making it the closest FRB to Earth ever localized. The burst called FRB 180916.J0158+65 was observed by a group of eight radio telescopes, including the 100-meter Effelsberg telescope.

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 thus far are in disagreement.

The team’s new measurement of the Hubble Constant, or the expansion rate of the universe, involved a different method. They used NASA’s Hubble Space Telescope (HST) in combination with W. M. Keck Observatory’s Adaptive Optics (AO) system to observe three gravitationally-lensed systems. This is the first time ground-based AO technology has been used to obtain the Hubble Constant

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 Fangjun at the Institute of High Energy Physics of the Chinese Academy of Sciences, provides important clues to the spin-down mechanism and the magnetic field structure of the pulsar, as well as the physical properties of the PWN. The results were published in Nature Astronomy.
