Nebula encasing RCW 38 (credit:ESO/VVVX survey) Our modern, highly efficient cameras and massive telescopes allow us to not only do massive surveys, they also allow us to see specific objects in previously unimagined detail. The 4-m Visible and Infrared Survey Telescope, or VISTA, in Chile recently completed a highly detailed mosaic of the RCW 38 star forming region. Just 5500 light years away, this system is less than a million years old. By studying its 2000 young stars, we can gain new insights into how stars and their surrounding solar systems form.  With even larger telescopes, we...

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...

A composite of Stephan’s Quintet, a visual grouping of five galaxies, constructed from almost 1,000 separate image files from the James Webb Space Telescope. UCLA astrophysicists believe if cold dark matter theories are correct, the Webb telescope should find tiny,...
