The galaxy cluster MACS-J0417.5-1154 is so massive that it bends the fabric of space-time. This causes the appearance of galaxies behind it to be distorted, an effect known as gravitational lensing. This natural phenomenon magnifies distant galaxies and can also make them appear in an image multiple times, as NASA's James Webb Space Telescope has observed. In this image, two distant, interacting galaxies - a face-on spiral and a dusty red galaxy seen from the side - appear multiple times, tracing a familiar shape across the sky. The fact that these galaxies are actively forming stars and that the face-on galaxy's spiral shape is remarkably intact indicates that their interaction is just beginning.

A powerful laser is directed into a jet of gas, forming a bright plasma that generates ultraviolet light. As this light interacts with the remaining gas in the vacuum chamber, it creates a visible white line. This method allows scientists to accurately measure the energy required to excite the thorium-229 nucleus, which is crucial for developing a future nuclear clock.

Contour plots (A, C, E, G) compare the input conditions, traditional finite difference method solutions, and the solutions generated by model B3, the most advanced model in the study. Velocity profiles (B, D, F, H) display detailed velocity information at specific cross-sections of the simulation domain.

A model developed by evolutionary mathematicians in Canada and Europe reveals that as cooperation becomes easier, it can unexpectedly break down. Researchers from the University of British Columbia and the Hungarian Research Network used computational spatial models to arrange individuals from two species on separate, facing lattices.

Kobe University researcher Naoyuki Hirata was the first to discover that an asteroid impact on Jupiter's moon Ganymede occurred almost exactly on the meridian farthest from Jupiter. This finding suggested that Ganymede had experienced a reorientation of its rotational axis, enabling Hirata to calculate the type of impact that could have caused this shift.

One of the few galaxies with a well-studied stellar halo is our neighbor, Andromeda, depicted here in the graphic. The reason Andromeda’s halo can be investigated so thoroughly is simply a matter of distance, both being close enough and bright enough that we can see the full picture with our current class of telescopes.
