Unveiling NF1: A rare double white dwarf system in the NGC 6397 globular cluster, located 7,800 light-years from Earth. This "nonflickerer" duo, detected using VLT's MUSE, features a visible helium-core white dwarf (NF1 B) and a likely invisible companion (NF1 A) orbiting each other every 13 hours, amidst a dense graveyard of stellar cores.

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.
