On May 16, 2016, the bread loaf-sized Miniature X-Ray Solar Spectrometer, or MinXSS, CubeSat deployed from an airlock on the International Space Station to begin its journey into space. The NASA-funded MinXSS studies emissions from the sun that can affect our communications systems.
MinXSS will operate for up to 12 months. The CubeSat observes soft X-rays from the sun, which can disrupt Earth's upper atmosphere and hamper radio and GPS signals traveling through the region.
The intensity of the soft x-ray emissions emitted from the sun is continuously changing over a large range - with peak emission levels occurring during large eruptions on the sun called solar flares.
MinXSS data will also help us understand the physics behind solar flares. The soft X-rays carry information about the temperature, density and chemical composition of material in the sun's atmosphere, allowing scientists to trace how events like flares and other processes heat the surrounding material in the sun's atmosphere - which are still being debated among solar scientists.
?CubeSats are a new, low-cost tool for space science missions. Instead of the traditional space science missions that carry a significant number of custom-built, state-of-the-art instruments, CubeSats are designed to take narrowly targeted scientific observations, with only a few instruments, often built from off-the-shelf components.
For example, MinXSS uses a commercially purchased X-ray spectrometer for a detector and an extendable tape measure as a radio antenna. The MinXSS development program was funded by the NASA Science Mission Directorate CubeSat Initiative Program and implemented by the University of Colorado Boulder under the leadership of Principal Investigator Tom Woods.
MinXSS was launched via the NASA CubeSat Launch Initiative program on Dec. 6, 2015, aboard Orbital ATK's Cygnus spacecraft through NASA's Commercial Resupply Services contract.
Since its inception in 2010, the CSLI has selected more than 120 CubeSats for launch and deployed 43 small satellites as part of the agency's Launch Services Program's Educational Launch of Nanosatellite Missions.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
