Scientists want to put an ultra-stable laser clock in a freezing lunar crater.

The Lunar Master Clock: Establishing an ultra-precise timekeeping system on the Moon using cryogenic technology and passive cooling, paving the way for advanced navigation, synchronization, and a new era of GPS-like guidance for lunar missions.
Deep in the early universe, 8.5 billion years ago, a galaxy is being torn apart. Its gas is stripping away in long, star-forming tentacles.
Astrophysicists from the University of Waterloo have spotted the most distant "jellyfish galaxy" ever seen. Using the James Webb Space Telescope (JWST), they peered into the COSMOS field—a patch of sky far from our own galaxy's dust.
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.
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.
