James Webb-teleskopet visar den tydligaste kartan av det kosmiska nätet

Astronomer som använder NASA:s James Webb-teleskop har tagit fram den mest detaljerade kartan hittills av universums kosmiska nät, det enorma nätverk av mörk materia och gas som binder samman galaxer. Kartan spårar strukturer tillbaka till när universum var ungefär en miljard år gammalt.

Forskare vid University of California, Riverside ledde ett internationellt team som analyserade mer än 164 000 galaxer som en del av COSMOS-Web-undersökningen. Resultaten, som publicerats i The Astrophysical Journal, visar filament och tomrum med betydligt större detaljrikedom än tidigare bilder av samma region tagna med Hubble-teleskopet.

Astronomers using the James Webb Space Telescope have identified the farthest jellyfish galaxy observed to date, located at a redshift of z=1.156. This galaxy, viewed as it appeared 8.5 billion years ago, features trailing streams of gas and young stars shaped by ram-pressure stripping in a dense cluster. The finding suggests that early universe galaxy clusters were more turbulent than previously thought.

Astronomers using the James Webb Space Telescope have identified a massive galaxy that shows no rotation, formed less than 2 billion years after the Big Bang. The finding challenges existing models of galaxy evolution.

Astronomers have produced a detailed map of the Milky Way's magnetic field, revealing a surprising diagonal reversal in the Sagittarius Arm. The findings, based on new radio telescope data, help explain how this invisible force structures the galaxy. Led by scientists at the University of Calgary, the studies were published this month in The Astrophysical Journal.

Astronomers have detected the brightest and most distant maser, a laser-like beam of microwaves, produced by colliding galaxies nearly 8 billion light years away. The discovery was made using the MeerKAT telescope in South Africa. This phenomenon, amplified by gravitational lensing, may represent a new category of extremely powerful masers.
