Astronomers and students at UK universities and observatories can use their PCs to spot stars as faint as a candle on the Moon using a record-breaking new telescope.
NGC 6744 is a large face-on barred spiral galaxy in the star-rich southern constellation of Pavo. It lies at a distance of approximately 30 million light years, and spans almost 150 000 light years in diameter. NGC 6744 is often considered one of the most Milky Way-like galaxies known.
The Southern African Large Telescope (SALT), the largest in the southern hemisphere and equal to the largest in the world, was built by partners in six countries including a UK consortium consisting of Armagh Observatory, the University of Keele, the University of Central Lancashire, the University of Nottingham, the Open University and the University of Southampton.
The £11 million SALT project has now released its first colour images from space, five years after construction started. The UK associates, along with partners in Germany, Poland, New Zealand, South Africa and the USA, have been amazed at the quality of the images, which are the first taken by SALT’s new $600,000 digital camera, SALTICAM.

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:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
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...
