Part of the simulated universe. Credit: The AGORA Collaboration In a paper that made me do math, researchers have shared the results of a remarkable new suite of simulations that explore how galaxies are born, live, and evolve. Over 160 researchers from 60...

False-colour JWST image of a small fraction of the GOODS South field, with JADES-GS-z7-01-QU highlighted. Credit: JADES Collaboration In a paper in Nature, with Tobias Looser as the first author, researchers discuss a galaxy cataloged as JADES-GS-z7-01-QU. This...

This image from Webb’s NIRCam (Near-Infrared Camera) instrument shows a portion of the GOODS-North field of galaxies. At the lower right, a pullout highlights the galaxy GN-z11, which is seen at a time just 430 million years after the Big Bang. One prominent...

This illustration provided by the European Southern Observatory in February 2024, depicts the record-breaking quasar J059-4351, the bright core of a distant galaxy that is powered by a supermassive black hole. The supermassive black hole, seen here pulling in...

Galaxy AM 1054-325 has been distorted into an S-shape from a normal pancake-like spiral shape by the gravitational pull of a neighboring galaxy, seen in this Hubble Space Telescope image. A consequence of this is that newborn clusters of stars form along a...

An illustration of a magnetic field generated by a supermassive black hole in the early universe, showing turbulent plasma outflows that help turn nearby gas clouds into stars. New findings suggest this process might be responsible for accelerated star formation in...

A color-composite image of PEARLSDG made with JWST NIRCAM data. Individual stars are visible as small points of light in the image. Its somewhat dull color and lack of many bright stars is consistent with its old age and lack of ongoing star formation. Credit: Image...

Artist’s impression of an outflow of molecular gas from the quasar J2054-0005. Credit: ALMA (ESO/NAOJ/NRAO) Gas dynamics are more than a little complicated no matter where you look. The dynamics of gas in and around forming galaxies makes is particularly...
