Catching these impacts is a challenge, but thanks to the Lunar Reconnaissance Orbiter Camera (LROC), we can now spot fresh craters that appeared almost overnight.

The Role of Izaña-2 in Ensuring a Safer Orbital Environment for Satellites
As the threat from space debris becomes a daily concern for satellite operators, the European Space Agency is developing innovative technologies to keep our orbits safe. At the Izaña station in Spain, ESA's Izaña-1 and Izaña-2 laser-ranging stations are testing a high-precision method to track debris, prevent collisions, and eventually, even nudge junk out of the way.

TESS Telescope Reveals Interstellar Comet 3I/ATLAS Before Official Discovery
When an object from another star system visits ours, astronomers race to learn its secrets. But sometimes, the first clues are found not by looking forward, but by looking back. A new study reveals that the Transiting Exoplanet Survey Satellite (TESS)—a telescope designed to find planets around other stars—had captured images of our newest interstellar visitor, 3I/ATLAS, as far back as May 2025. Unearthing this "pre-discovery" data required a clever technique to find a faint,
