Navigating the Satellite Megaconstellation Crisis: This infographic illustrates the increasing congestion in Earth's orbit, with projections showing a rise from 14,000 active satellites to over 1.2 million. It highlights risks such as visibility interference and collision threats while proposing solutions like multi-stakeholder research and mandatory mitigation strategies to preserve astronomical, environmental, and cultural values.

The image highlights the discovery of 1,114 new Small Mare Ridges (SMRs) on the Moon, increasing the total to 2,634. These findings suggest recent tectonic activity, indicating the Moon is shrinking as its crust compresses. The implications include widespread sources of moonquakes and the necessity to reassess lunar landing sites for safety in future missions, especially the Artemis Program.

The Moon contracts, buckling its crust into ridges and scarps. A new study reveals these "wrinkles" are everywhere

As it cools, the Moon contracts, buckling its crust into ridges and scarps. A new study reveals these "wrinkles" are everywhere—and they might be dangerous. Unlike Earth, the Moon has no tectonic plates. It is a single-plate planet. Yet, it is seismically active. Why? Because it is shrinking.

Unveiling Galaxy CDG-2: This infographic details a "dark" galaxy where 99% of its mass is invisible dark matter. Stripped of star-forming gas and with a sparse stellar population, CDG-2 was detected using globular clusters as tracers. It is the first galaxy discovered solely via clusters, with its existence confirmed by data from Hubble, the Euclid space observatory, and the Subaru Telescope.

A galaxy made of 99% dark matter, betraying its presence only by four tiny clusters of stars.

In the shadows of a galaxy cluster, astronomers have found a phantom. A galaxy made of 99% dark matter, betraying its presence only by four tiny clusters of stars. Most galaxies shine bright. But CDG-2 is a "Low-Surface-Brightness" galaxy, so faint it's nearly invisible. It contains only a sparse scattering of stars.
