Tiny little bullets flood the solar system, each micrometeoroid a potential hazard. New research has found that the James Webb Space Telescope's thin sunshields, and future inflatable spacecraft, may be at risk.
A micrometeoroid is a tiny bit of space junk usually weighing less than a gram. Some of them are the leftover bits of the countless collisions that have occurred over the past 4.5 billion years of the history of the solar system. Most, however, come from the dust cloud that initially collapsed to form our solar system, and never got to be a part of a larger body.

As Artemis sets its sights on the Moon, powered by the European Service Module (ESM), all eyes will again turn to the night sky. This interactive publication encourages us to look up at our natural satellite and think about how the Moon has inspired us, from Ancient Greece to the 21st century, to develop our understanding of astronomy, physics and our place in the Solar System.
How space is connecting cars

On Thursday, May 5, mission controllers at NASA's Jet Propulsion Laboratory received confirmation that the agency's Ingenuity Mars Helicopter had re-established communications with the Perseverance rover. Earlier in the week, the rotorcraft had missed a planned communications session with the rover - for the first time in over a year of operations on the Mars surface.

With a sophisticated combination of human and artificial intelligence, astronomers uncovered 1701 new asteroid trails in archival data of the Hubble Space Telescope spanning the past 20 years. While about one third could be identified and attributed to known objects, more than 1000 trails probably correspond to previously unknown asteroids. These unidentified asteroids are faint and likely small Chinese scientists find potential in lunar soil to generate oxygen and fuel

Scientists from the RIKEN Cluster for Pioneering Research have used computer modeling to show how a hypothesized type of supernova would evolve on the scale of thousands of years, giving researchers a way to look for examples of supernovae of this model, known as "D6."
Supernovae are important for cosmology, as one type, Ia, is used as a "standard candle" that allows distance to be measure
