New views of star birth and the heart of a spiral galaxy have been seen by a state-of-the-art astronomical instrument on its first night. The new UKIRT Imaging Spectrometer (UIST) has a revolutionary ability to slice any object in the sky into sections, producing a three dimensional view of the conditions throughout entire galaxies in a single observation. UIST has just been installed on the United Kingdom Infrared Telescope (UKIRT) in Hawaii.

Project scientist Suzanne Ramsay Howat from the UK Astronomy Technology Centre (ATC) in Edinburgh said "UIST will give astronomers using UKIRT a unique way of viewing the Universe, keeping this telescope at the cutting-edge of science".
The instrument saw its First Light on the night of 24th September, when it was trained on the Omega Nebula. This nebula, also called Messier 17, is a gas cloud where new stars are forming. Located 5000 light years from Earth, M17 is a near neighbor and can be studied in exquisite detail with an instrument such as UIST. The intense ultraviolet radiation from young, hot stars blasts the atoms in clouds of interstellar gas, making them glow brightly as seen in the bottom right of the UIST image.

Researchers from the Department of Atomically Resolved Dynamics of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Potsdam (both in Germany) and the University of Toronto (Canada) have pieced together a detailed time-lapse movie revealing all the major steps during the catalytic cycle of an enzyme. Surprisingly, the communication between the protein units is accomplished via a water-network akin to a string telephone. This communication is aligned with a ‘breathing’ motion, that is the expansion and contraction of the protein.
This time-lapse sequence of structures reveals dynamic motions as a fundamental element in the molecular foundations of biology.
Two research teams have succeeded simultaneously in measuring the long-sought Thorium nuclear transition, which enables extremely precise nuclear clocks. TU Wien (Vienna) is part of both teams.
If you want to build the most accurate clock in the world, you need something that "ticks" very fast and extremely precise. In an atomic clock, electrons are...
Researchers from Chalmers University of Technology have demonstrated a detector made from graphene that could revolutionize the sensors used in next-generation space telescopes. The findings were recently published in the scientific journal Nature Astronomy.
Beyond superconductors, there are few materials that can fulfill the requirements needed for making ultra-sensitive and fast terahertz (THz) detectors for...
A supersolid is a state of matter that can be described in simplified terms as being solid and liquid at the same time. In recent years, extensive efforts have been devoted to the detection of this exotic quantum matter. A research team led by Tilman Pfau and Tim Langen at the 5th Institute of Physics of the University of Stuttgart has succeeded in proving experimentally that the long-sought supersolid state of matter exists. The researchers report their results in Nature magazine.
In our everyday lives, we are familiar with matter existing in three different states: solid, liquid, or gas. However, if matter is cooled down to extremely...
A team headed by Prof. Steve Albrecht from the HZB will present a new world-record tandem solar cell at EU PVSEC, the world's largest international photovoltaic and solar energy conference and exhibition, in Marseille, France on September 11, 2019. This tandem solar cell combines the semiconducting materials perovskite and CIGS and achieves a certified efficiency of 23.26 per cent. One reason for this success lies in the cell’s intermediate layer of organic molecules: they self-organise to cover even rough semiconductor surfaces. Two patents have been filed for these layers.
Perovskite-based solar cells have experienced an incredibly rapid increase in efficiency over the last ten years. The combination of perovskites with classical...
