One mystery has been whether the jets exist only in the planet's upper atmosphere—much like the Earth's own jet streams—or whether they plunge into Jupiter's gaseous interior. If the latter is true, it could reveal clues ...

(Phys.org)—A team of researchers with the University of California has developed a new technique for converting sugarcane biomass into jet fuel that they claim reduces greenhouse gas emissions by 80 percent. In their paper ...
New research using data from NASA's Cassini mission suggests most of the eruptions from Saturn's moon Enceladus might be diffuse curtains rather than discrete jets. Many features that appear to be individual jets of material ...

(Phys.org) —A team of space scientists working in Italy has found more evidence that suggests the energy needed to emit jets from supermassive black holes comes from the spin of the black hole itself. In their paper published ...
In a design that mimics a hard-to-duplicate texture of starfish shells, University of Michigan engineers have made rounded crystals that have no facets.
