This artist's conception shows a disk of dust and gas surrounding a young star with a large cavity carved out by a forming giant planet. The warm methanol gas tracing the dust cavity wall is highlighted. These molecules originate from ices rich in organic matter that are heated by radiation from the star, forming gas. The detection of methanol, as well as the methanol isotopes, supports the idea that interstellar ices can survive the formation of planet-forming disks. Credit: CfA/M. Weiss

Big Bang, conceptual image. Computer illustration representing the origin of the universe. The term Big Bang describes the initial expansion of all the matter in the universe from an infinitely compact state 13.7 billion years ago. The initial conditions are not known, but less than a second after the beginning, temperatures were trillions of degrees Celsius and the primordial universe was much smaller than an atom. It has been expanding and cooling ever since. Matter formed and coalesced into the galaxies, which are observed to be moving away from each other. Background radiation in the universe is considered a remnant of the Big Bang.

For this study, writing styles in digitized manuscripts were analyzed using BiNet, a previously developed deep neural network for detection of handwritten ink-trace patterns. By combining writing styles with carbon-14 dates of manuscripts using artificial intelligence, the date-prediction model Enoch is able to produce an accurate date for the manuscript.

NASA's James Webb Space Telescope recently imaged the Sombrero galaxy with its NIRCam (Near-Infrared Camera), which shows dust from the galaxy's outer ring blocking stellar light from stars within the galaxy. In the central region of the galaxy, the roughly 2,000 globular clusters, or collections of hundreds of thousands of old stars held together by gravity, glow in the near-infrared. The Sombrero Galaxy is around 30 million light-years from Earth in the constellation Virgo. From Earth, we see this galaxy nearly "edge-on," or from the side. Credit: NASA, ESA, CSA, STScI

Artist's conception of a supermassive black hole, billions of times more massive than the sun, like those found at the centers of galaxies. The black hole's rapid spin and powerful magnetic fields can launch enormous jets of plasma into space, a process that could potentially generate the same results as human-made supercolliders.

The densest cluster of supermassive black holes identified in the universe. The background image was taken by Hyper Suprime-Cam on the Subaru Telescope. The red and blue shadows represent the density of the supermassive black holes (quasars) and the surrounding hundreds of young, star-forming galaxies, respectively. The white squares frame the quasars, and the larger squares show close up images. Credit: Subaru Telescope / SDSS, Liang et al

An SwRI-led study identified particles accelerated to extremely high energies by magnetic reconnection near the Sun. As NASA's Parker Solar Probe (trajectory shown in green) crossed the heliospheric current sheet, it encountered merging magnetic islands (blues) and protons accelerated toward the Sun, establishing reconnection as their source, distinct from unrelated solar processes.

This artistic impression depicts the stage at which WASP-121b accumulated most of its gas, as inferred from the latest results. The illustration suggests that the forming planet had cleared its distant orbit of solid pebbles, which stored water as ice. As a result, the gap prevented additional pebbles from reaching the planet. WASP-121b must have subsequently migrated from the cold, outer regions towards the inner disc, where it now orbits near its star.. Credit: T. Müller (MPIA/HdA - CC BY-SA)
