Lancaster UK (SPX) Jan 26, 2022
A Lancaster physicist has proposed a radical solution to the question of how a charged particle, such as an electron, responded to its own electromagnetic field. This question has challenged physicists for over 100 years but mathematical physicist Dr Jonathan Gratus has suggested an alternative approach - published in the Journal of Physics A- with controversial implications. It is w

ESA engineers need to be certain of the strength and tensile behaviour of candidate materials for coming space missions - so they pull them apart. This tensile testing machine (otherwise known as a universal testing machine) does exactly that: a test sample is placed between its two sets of 'jaws' and subjected to a steadily increasing pull force, until the moment of fracture. The ap

The South African Radio Astronomy Observatory (SARAO) has released a new MeerKAT telescope image of the centre of our Galaxy, showing radio emission from the region with unprecedented clarity and depth. The international team behind the work is publishing the initial science highlights from this image in The Astrophysical Journal. The article is accompanied by a public release of the data to the

An unprecedented new telescope image of the Milky Way galaxy's turbulent center has revealed nearly 1,000 mysterious strands, inexplicably dangling in space. Stretching up to 150 light years long, the one-dimensional strands (or filaments) are found in pairs and clusters, often stacked equally spaced, side by side like strings on a harp. Using observations at radio wavelengths, Northwester

Can machine learning be used to uncover the secrets of the quark-gluon plasma? Yes - but only with sophisticated new methods. It could hardly be more complicated: tiny particles whir around wildly with extremely high energy, countless interactions occur in the tangled mess of quantum particles, and this results in a state of matter known as "quark-gluon plasma". Immediately after the Big B

The test version of NASA's Volatiles Investigating Polar Exploration Rover, or VIPER, kicks up high sinkage sand-like material while transiting NASA Glenn's Simulated Lunar Operations Laboratory, or SLOPE bed. In November 2021, the latest test rover visited SLOPE to complete the next iteration of mobility testing, a critical step toward ensuring the rover is ready for its 2023 mission to the Moo

Nuclear scientists have used a powerful particle accelerator to create matter directly from collisions of light. Scientists predicted this process in the 1930s, but it has never been achieved in a single direct step. The researchers accelerated two beams of gold ions to close to the speed of light in opposite directions. At such speeds, each gold ion is surrounded by particles of light (re

From a seaside perch overlooking the hustle and bustle of ships coming and going at Port Canaveral on Florida's east coast, Dale Ketcham reflects on decades of history with nostalgia. "I moved here and learned how to walk on Cocoa Beach three years before NASA was created" in 1958, he said. Not only can Ketcham trace his life alongside the U.S. space program, he's had a firsthand vie

NASA has selected 12 companies to provide launch services for the agency's Venture-Class Acquisition of Dedicated and Rideshare (VADR) missions, providing new opportunities for science and technology payloads and fostering a growing U.S. commercial launch market. The fixed-price indefinite-delivery/indefinite-quantity contracts have a five-year ordering period with a maximum total value of

Swarms of hundreds or thousands of small satellites are increasingly used for bringing data and internet services to Earth. To position, communicate and dispose such large amounts of satellites, Artificial Intelligence is getting increasingly important. To enable a large-scale use of Artificial Intelligence in orbit, RUAG Space, Europe's leading supplier to the space industry, and Stream A
