Dimitri Mendeleev, a Russian, and Lothar Meyer, a German, published early versions of periodic tables in 1869 and 1870, respectively. Well, roll over, Mendeleev, tell Meyer the news: Washington Universitys Katharina Lodders has developed an innovative periodic table, slanted toward astronomy, thats definitely not your fathers periodic table.

Revised periodic table slanted toward astronomers
The periodic table isn’t what it used to be, thanks to innovations by a planetary chemist at Washington University in St. Louis.
Katharina Lodders, Ph.D., Washington University research associate professor in Earth and Planetary Sciences in Arts & Sciences, has evalutated data from numerous studies including her own and arranged the data into a periodic table slanted toward astronomers and cosmochemists. It’s the Cosmochemical Periodic Table of the Elements in the Solar System. Instead of atomic number, atomic weights, and melting- and boiling points, for example, Lodders provides elemental abundances and condensation temperatures. And it’s color-coded to indicate host phases of the elements - the phase where the element condenses into metal, sulfide, or silicate rock.

Deep inside Galaxy M87
20.04.2017 | Max-Planck-Institut für Radioastronomie
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
