Large Binocular Telescope images Jupiter’s moon IoOld Telescope Shows Off New Skills

Meanwhile on Earth, the Large Binocular Telescope has installed a new high-contrast optical imaging instrument, dubbed SHARK-VIS. Using adaptive optics, the system can compensate for the earth’s atmosphere, and with a pair of 9m mirrors, it has resolutions and light gathering capabilities that allow it to do what were previously considered impossible actions. Like… imaging Io with enough detail that we can expect to see changes in lava fields as Io's volcanoes flow over and change its surface in the decades to come.

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...

Black Holes Formed Before Stars

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...

Unexpected Galaxy Photobombs Cluster

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...

Explaining Early Bright Galaxies

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,...
