Argon on Uranus and Neptune may reveal more about their origins than their interiors

Measurements of an argon isotope could help scientists understand whether the interiors of Uranus and Neptune, our solar system's so-called ice giants, are dominated by ice or rock. New research led by Southwest Research Institute (SwRI) and published in The Planetary Science Jou
Measurements of an argon isotope could help scientists understand whether the interiors of Uranus and Neptune, our solar system's so-called ice giants, are dominated by ice or rock. New research led by Southwest Research Institute (SwRI) and published in The Planetary Science Journal measured the planets' atmospheric argon-40 to estimate the amount of rock found beneath their surfaces and search for clues about the planets' origins, including where and how they formed.

Centaurus A in the spotlight: Plasma simulations reproduce black hole jets' mysterious bright edges
Around 12 million light-years away, the supermassive black hole of the galaxy Centaurus A is hurling two enormous plasma jets into space at nearly the speed of light. These so-called jets are brighter at their edges than at their center. The reason for this was previously unclear

Why some dinosaurs get all the attention and others don't
If you ask anyone to name a dinosaur, there's a good chance they'll say Tyrannosaurus rex, that fearsome prehistoric predator with its enormous jaws and razor-sharp teeth. But what about a lesser-known dinosaur such as Iguanodon or Plateosaurus? Probably not.

A gold–copper strategy for building interlocked nitrogen-doped carbon nanohoops
Catenanes are molecules in which two or more rings are mechanically interlocked like the links of a chain, without any chemical bonds between them. Since Jean-Pierre Sauvage, who later shared the 2016 Nobel Prize in Chemistry, reported an efficient metal-templated synthesis in 19
