Further results from the Cassini spacecraft’s July flyby of Saturn’s moon, Enceladus, reveal more detail about the features and processes going on. Speaking at a press conference at Imperial College, London this morning (30th August) the Cassini scientists spoke about the intriguing south pole area which has a surprising hotspot and “tiger stripe” features on the surface.
Following the two distance flybys of Enceladus in February and March this year results from the Magnetometer instrument showed a flowing of the magnetic and plasma field from Saturn towards and then around Enceladus. Effectively Enceladus was acting as an obstacle to the flow – indicating the presence of an atmosphere. In addition there was an indication of an internal signature.
Professor Michele Dougherty from Imperial College is the lead scientist for the Magnetometer instrument. She takes up the story.
Dr. Torrence Johnson from NASA’s Jet Propulsion Laboratory is a member of the ISS team. He said, “Enceladus has certainly thrown up more surprises than anticipated – which is great for planetary science. We are piecing together the results from the various instrument teams to build up more of a complete picture of what is happening on Enceladus. With more data analysis and further flybys planned we are beginning to understand more about this icy satellite.”

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...
