A long-lost type of dark matter may resolve the biggest disagreement in physics

 

“We Exist Within a Colossal Sphere” –The Void that Harbors the Milky Way (Weekend Feature) | The Daily Galaxy

    Our Milky Way Galaxy exists in void –one of the vast holes of the “Swiss-cheese” structure of the cosmos– with a radius measuring roughly 2 billion light years in diameter –the largest void known to science, shaped like a sphere with a shell of increasing thickness made up of galaxies, stars and other …

Swift Mission Observed Water from Interstellar Comet Borisov – Astrobiology

For the first time, NASA’s Neil Gehrels Swift Observatory tracked water loss from an interstellar comet as it approached and rounded the Sun. The object, 2I/Borisov, traveled through the solar system in late 2019.

“Borisov doesn’t fit neatly into any class of solar system comets, but it also doesn’t stand out exceptionally from them,” said Zexi Xing, a graduate student at the University of Hong Kong and Auburn University in Alabama who led the research. “There are known comets that share at least one of its properties.”

New research shows interstellar visitor 21/Borisov is not your average comet

Two new separate studies published in Nature today have revealed that our second interstellar visitor, 21/Borisov, packs in three times as much CO than any other comet found wandering in the inner Solar System – a feature that gives astronomers a clue as to where it formed

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.
