Black and white reproductions of Vincent van Goghs "The Starry Night" lack the beauty and depth of the original oil painting. In a similar fashion, images of stars and galaxies composed of a single wavelength band cannot convey the wealth of information now accessible to astronomers.
This false-color image shows infrared (red), optical (green), and X-ray (blue) views of the N49 supernova remnant. This object, the remains of an exploded star, has million-degree gas in the center, with much cooler gas at the outer parts of the remnant.

This false-color image shows infrared (red), optical (green), and X-ray (blue) views of the large star-forming complex N51. The warm ionized gas is shown in green, the hot ionized gas is in blue, and the proto-stars are primarily in red. Credit: NASA/SSC/MCELS/ESA/U.Illinois (Y.-H. Chu and R. A. Gruendl)
In recent years, a number of ground-based optical and radio surveys of the Large and Small Magellanic Clouds -- Earths nearest neighboring galaxies -- have become available. New composite images of optical, radio, infrared, ultraviolet and X-ray wavelengths are giving astronomers at the University of Illinois at Urbana-Champaign a clearer picture of the birth, life and death of massive stars, and their effect on the gas and dust of the interstellar medium surrounding them.
From their birth to their death, massive stars have a tremendous impact on their galactic surroundings. While alive, these stars energize and enrich the interstellar medium with their strong ultraviolet radiation and their fast stellar winds. As they die, shock waves from their death throes inject vast quantities of mechanical energy into the interstellar medium and can lead to the formation of future stars.

Dead and alive at the same time? Researchers at the Max Planck Institute of Quantum Optics have implemented Erwin Schrödinger’s paradoxical gedanken experiment employing an entangled atom-light state.
In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. The crucial element of this gedanken...
Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
Just in time for Christmas, a Mars-analogue mission in Morocco, coordinated by the Robotics Innovation Center of the German Research Center for Artificial Intelligence (DFKI) as part of the SRC project FACILITATORS, has been successfully completed. SRC, the Strategic Research Cluster on Space Robotics Technologies, is a program of the European Union to support research and development in space technologies. From mid-November to mid-December 2018, a team of more than 30 scientists from 11 countries tested technologies for future exploration of Mars and Moon in the desert of the Maghreb state.
Close to the border with Algeria, the Erfoud region in Morocco – known to tourists for its impressive sand dunes – offered ideal conditions for the four-week...
