Galileo, the NASA space probe in which UK scientists have played a key role, will dramatically end its 14-year mission when it plunges into Jupiters dense atmosphere on the 21st September. The spacecraft, which has revealed a wealth of scientific data on Jupiter and its moons, with fuel and power exhausted, will vaporize like a meteor as its descends through the giant planets turbulent atmosphere (an artists impression of what this might look like is available - please see notes to editors).

As well as extensive scientific data, Galileo has provided the most visually stunning images of Jupiter and its moons ever, especially Io and Europa. The probe, launched in 1989 by the Space Shuttle Atlantis, also imaged the Earth, Venus, the Moon and several asteroids during its lifetime.
The highlights of the mission include the identification of massive amounts of lightening activity in Jupiters atmosphere, where hurricane-force winds and huge amounts of heat from the interior whip clouds of frozen ammonia into bands that encircle the planet, studded with giant storms, some of them larger than the entire Earth. The planet is richer in heavy elements than the Sun, showing that it was assembled from smaller planetesimals rather than condensing in isolation as previously surmised.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
