Observations of quasars reveal that many supermassive black holes (BHs) were in place less than 700 Myr after the Big Bang. However, the origin of the first BHs remains a mystery. Seeds of the first BHs are postulated to be either light (that is, 10−100 M⊙), remnants of the first stars, or heavy (that is, 10−105 M⊙), originating from the direct collapse of gas clouds. Here, harnessing recent data from the Chandra X-ray Observatory, we report the detection of an X-ray-luminous massive BH in a gravitationally lensed galaxy identified by the James Webb Sp...

An international team of scientists have used data collected by the NASA/ESA/CSA James Webb Space Telescope to detect for the first time ever a molecule known as methyl cation (CH3+), located in the protoplanetary disc surrounding a young star. They

An international team of researchers including the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) has studied the relationship between galaxy size and luminosity of some of the earliest galaxies in the universe taken by the brand-new James Webb Space Telescope (JWST), less than a billion years after the Big Bang, reports a new study in The Astrophysical Journal Letters.

The distant bundles of stars are far brighter than anyone expected, challenging views of how the cosmos first took shape.

Webb's capability to look deeper into the universe than other telescopes is revealing previously hidden aspects of the universe, including astonishingly distant galaxies such as these two finds.
