Astronomers throughout the UK now have a valuable new research tool at their disposal which may lead to new discoveries and improved understanding of the physics of the Universe. Launched this week, AstroGrid provides a unique way of accessing, processing and storing astronomical data obtained from a diverse range of data archives held anywhere on Earth. AstroGrid will open the way for virtual observing on individual computers, enabling astronomers to compare and manipulate a wide range of astronomical data taken from both ground and space-based telescopes.
Astronomy is now in a golden age of discovery, with many new breakthroughs being made with the availability of high quality observations of the cosmos from major new observational facilities, such as the European Southern Observatorys Very Large Telescope [VLT] in Chile and the European Space Agencys XMM-Newton space-based observatory, which provide information across a wide range of the electro-magnetic spectrum from radio to visible light to gamma rays.
The data taken from ground and space-based observations are held in separate archives and the challenge has been to provide the astronomer with the ability to bring these various pieces of data together, enabling them to understand the wider picture. For example one astronomer may survey the sky in the optical wavelengths, using the Sloan Digital Sky Survey, whilst another astronomer may analyse data from the XMM-Newton, each resulting in different answers. Only by comparing the two sets of data, or even adding another data set (e.g. Infrared data from Spitzer), can they then discover that certain previously insignificant faint objects seen in the optical are in fact distant galaxies harbouring massive black holes at their core.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
