At the same time they have also discovered a new way to realize an optically controlled light switch that can be used to manipulate light with light, an…
Whether such mergers are important in the formation of the tiniest galaxies has been the subject of debate among theoreticians. Now, thanks to research by two…
“This is how galaxies grow. You can see the smaller galaxy coming in and getting shredded, eventually leaving its stars scattered through the halo of the host…
For several years Chandra has detected X-ray flares about once a day from the supermassive black hole known as Sagittarius A*, or “Sgr A*” for short. The…
Knowing how to control the combined magnetic properties of interacting electrons will provide the basis to develop an important tool for advancing spintronics:…
Boston—Boston University astrophysicist Elizabeth Blanton led a team of researchers in the discovery of vast clouds of hot gas “sloshing” in Abell 2052, a…
Nowadays, large laser systems provide ultra-short light pulses of very high intensity which – in principle – allow the imaging of matter and its dynamics on…
Most spiral galaxies in the Universe have a bar structure in their centre, and Hubble's image of NGC 1073 offers a particularly clear view of one of these….
The CERES results help scientists to determine the Earth's energy balance, providing a long-term record of this crucial environmental parameter that will be…
This observation provides a unique opportunity to study the physical properties of a galaxy vigorously forming stars when the universe was only one-third its…
The formation of millisecond pulsars is the result of stellar cannibalism where matter flows from a donor star to an accreting pulsar in a binary system….
Solid-state memory is seeing an increase in demand due to the emergence of portable devices such as tablet computers and smart phones. Spin-transfer torque…
Researchers supported by the Swiss National Science Foundation (SNSF) have demonstrated a microscopic system in which light can be converted into a mechanical…
Scientists from Dresden University of Technology in Germany have set out to build energy efficient organic LED (OLED) lights that could rival incandescent…
In a paper accepted for publication in the AIP's journal Review of Scientific Instruments, a researcher at the National Institutes of Standards and Technology…
Researchers have searched for ways to prolong battery life – trying to generate energy to power a pacemaker using blood sugar, or the motion of the hands and…
