The LSST is a US project headquartered in Arizona that is building a revolutionary new design of telescope that has a field of view 1000 times larger than that of existing large telescopes and a world-class light gathering capability.
Every aspect of the project will be record breaking. The field of view, at ten square degrees, could accommodate fifty full moons. The LSST will image an area of the sky roughly fifty times that of the full moon every 15 seconds, opening a movie-like window on objects that change or move on rapid time scales: supernovae explosions which can be seen halfway across the universe, nearby asteroids which might potentially strike Earth, and faint objects in the outer solar system, far beyond Pluto.
Using the light-bending gravity of dark matter, the LSST will chart the history of the expansion of the universe and probe the mysterious nature of dark energy.
The LSST has become possible because we are now able to make large, deeply curved mirrors to an accuracy thought impossible just ten years ago. The telescope will use three mirrors, an 8.4m primary, a 3.4m secondary and a 5.0m tertiary, with the first and last fabricated as a single monolith. This three stage reflection means that LSST is actually so compact that it could sit inside current generation telescope domes.
It has recently been announced that Cerro Pachón, a 2,680m high mountain peak in northern Chile, has been selected as the future site for the Large Synoptic Survey Telescope. The mountain already hosts other large telescopes including the Gemini South 8m reflecting telescope on which Observatory Sciences consultants have worked in the past.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
