What’s creating these unusual signals? And why does this one repeat itself?

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.

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
Early observations of Comet C/2019 Q4, which will likely be declared the first confirmed interstellar comet, suggest that its composition is pretty similar to that of comets found in our own solar system.

All you need are two black holes and a few cosmic strings and voila! Instant wormhole.

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.

A research team from Osaka University, Nihon University and Chuo University has proposed a novel theoretical framework whose experiment could be performed in a laboratory to better understand the physics of black holes. This project can shed light on the fundamental laws that govern the cosmos on both unimaginably small and vastly large scales.

A Canadian telescope spotted eight more repeating fast radio bursts. What causes these cryptic flashes of radio waves from deep space remains unclear.
A team of researchers recently pioneered the world’s first AI universe simulator. It’s fast; it’s accurate; and its creators are baffled by its ability to understand things about the cosmos that it shouldn’t. Scientists have used computer simulations to try and digitally reverse-engineer the origin and evolution of our universe for decades. The best traditional …
