Using the NASA/ESA/CSA James Webb Space Telescope, an international team of astronomers has discovered that dust and water can form and survive surprisingly close to the supermassive black hole at the center of the Milky Way galaxy. The observations reveal that the evolved star IRS 3 continues to enrich its surroundings with newly formed material despite the intense radiation environment around Sagittarius A*.

I’ll admit to using AI for things it was probably never designed for. When my van threw a fault I couldn’t immediately figure out—one that seems notorious for trips back and forth to a repair shop—I ended up in a long (but cheaper) back-and-forth with an AI system, working through the symptoms. The same happened with a run of gutters and with stud framing in my house. It isn’t magic, and perhaps more often than I’d like, it’s wrong, but as a way of thinking through a problem with something that’s read more manuals than I ever will, it has earned its place in the toolbox. So I read this next story with some sympathy and interest.

Most current space activities operate close to Earth in what is called near–Earth orbit. However, as more satellites and other infrastructure begin to extend beyond that region, maintaining situational awareness of those objects will be crucial.

Researchers at the University of Basel and the Technical University of Munich have developed a new method to reveal the collective motion of electrons in one of the most elusive states of matter: the Wigner crystal. Using light, the physicists were able to uncover previously inaccessible properties of this fragile quantum state.

For decades, astronomers have assumed that the Martian surface froze solid around 3 billion years ago and has stayed that way ever since. If this were really the case, any liquid water would have long since either been locked away underground or lost to space.

Every electronic and optoelectronic device generates heat, and today that heat is managed almost entirely from the outside. Heatsinks, fans, cold plates and refrigerators are bulky exterior measures bolted onto a chip or package after the fact. They treat heat as a single averaged quantity to be removed in bulk, even though the heat is actually produced locally, component by component, deep inside the circuitry.

In January 2024, physicists at TU Dortmund University demonstrated a continuous time crystal in a semiconductor whose oscillations remained stable for hours. In a new study published in Nature Communications, Professor Alex Greilich and his team show that many such time crystals can form in the same material and synchronize their electron-nuclear spin oscillations.

Hold on to your telescopes: The DESI Legacy Imaging Surveys team has released the largest-ever 2D color map of the universe. The 5.6-trillion-pixel map contains nearly 4 billion celestial objects, primarily stars and galaxies. The data is available for all to use and publicly view through the Legacy Survey Sky Viewer.
