The most remarkable discovery of recent years in the study of the interstellar medium has been the identification of spatial structures of sizes down to those of a few times the mean Earth-Sun distance (an Astronomical Unit , AU). Solar-System Scale microstructures are detected in cool clouds ...
Recordings of magnetic fields, thought to be crucial to our solar system’s rapid accretion, are potentially retained in unaltered nanometric low-Ni kamacite (~ metallic Fe) grains encased within dusty olivine crystals, found in the chondrules of uneq

2017). Although smaller (km-scale) asteroids are generally too faint for spectroscopy in the 3 \(\upmu \)m region, the activity of MBCs offers evidence that water is also present in at least some smaller asteroids. 3 The Main Belt Comets...

Besides catalysts, the reactor is also critical for SO3decomposition. The reactor using moving catalyst particles as the...
