NASA’s Webb Telescope will survey Saturn and Titan
If you stop a random person on the sidewalk and ask them what their favorite planet is, chances are their answer will be Saturn. Saturn’s stunning rings are a memorable sight in any backyard telescope. But there is still a lot to learn about Saturn, especially about the planet’s unique weather and chemistry, as well as the origin of its opulent…
Secure quantum communications in the microwave range for the first time
Mikel Sanz, of the Physical Chemistry Department of UPV/EHU, leads the theoretical group for an experiment published by the prestigious journal, Nature Communications. The experiment has managed to prepare a remote quantum state; i.e., absolutely secure communication was established with another, physically separated quantum computer for the first time in the microwave regime. This new technology may bring about a revolution…
Closer look at supernova dust suggests there’s more of it than previously assumed
A pair of researchers with the Max Planck Institute for Chemistry dust from a supernova have found evidence that suggests it is more abundant than thought. In their paper published in the journal Nature Astronomy, Jan Leitner and Peter Hoppe describe their use of new technology to examine grains of supernova dust and what they found.

The Long-Awaited Upgrade To the US Weather Forecast Model Is Here
An anonymous reader quotes a report from Ars Technica: For the first time in about 40 years, the guts of the U.S. model got swapped out for something new today. The upgrade brings us a new “Finite-Volume Cubed-Sphere” (or FV3) dynamical core, which simulates the basic atmospheric physics at the heart of this endeavor, a change that has been in the…
Chemistry of stars sheds new light on the Gaia Sausage
Chemical traces in the atmospheres of stars are being used to uncover new information about a galaxy, known as the Gaia Sausage, which was involved in a major collision with the Milky Way billions of years ago. Source: https://phys.org/news/2019-05-chemistry-stars-gaia-sausage.html…

New Paper Confirms Near-Room-Temperature Superconductivity In Wild, Hydrogen-Rich Material
An anonymous reader quotes a report from Gizmodo: A team of physicists has published peer-reviewed results documenting near-room-temperature superconductivity in the hydrogen-rich compound lanthanum hydride. The team, led by physicist Mikhail Eremets from the Max Planck Institute for Chemistry, kicked off the most recent race for a high-temperature superconducting hydride in 2015, when they published a paper announcing the discovery of…
Water formation on the moon
For the first time, a cross-disciplinary study has shown chemical, physical, and material evidence for water formation on the moon. Two teams from the University of Hawaiʻi at Mānoa collaborated on the project: physical chemists at the UH Mānoa Department of Chemistry’s W.M. Keck Research Laboratory in Astrochemistry and planetary scientists at the Hawai’i Institute of Geophysics and Planetology (HIGP). Source:…
