Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…
The nonlinear process of high-order harmonic generation (HHG) in gases is one of the cornerstones of attosecond science (an attosecond is a billionth of a…
The magnetic properties of a material control how this material responds to the presence of a magnetic field. Iron oxide is the main component of rust but also…
“This source of radiation lets us look at reality through a new angle – it is like twisting a mirror and discovering something completely different,” says…
A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes…
Researchers at Caltech have designed a way to levitate and propel objects using only light, by creating specific nanoscale patterning on the objects' surfaces.
Heavy elements are produced during stellar explosion or on the surfaces of neutron stars through the capture of hydrogen nuclei (protons).
The distance between the dots has now become big enough for integration with traditional microelectronics and perhaps, a future quantum computer. The result is…
ExoMars is a space mission of the European Space Agency (ESA) in cooperation with the Russian space agency Roskosmos. ExoMars stands for exobiology on Mars:…
For most people, a vacuum is an empty space. Quantum physics, on the other hand, assumes that even in this lowest-energy state, particles and antiparticles…
The team of Saarbrücken engineers will be exhibiting their technology at this year’s Hannover Messe from the 1st to the 5th of April at the Saarland Research…
“One of the key results of our work is a new and fairly unexpected way of indirectly studying the optical emission from the central regions of active galactic…
Astronomers from Japan, Taiwan and Princeton University have discovered 83 quasars powered by supermassive black holes in the distant universe, from a…
If you've ever been to an air show, or lived near an air force base, you're familiar with sonic booms.
It is not yet identified where and how elements heavier than iron in the universe have been made. Drawing attention as one of the origins of the heavy elements…
Ultrafast lasers with pulse durations in the picosecond and femtosecond range have experienced a major boom over the past few years. Several innovations in…
Recently, scientists have been actively working on miniature light sources or nanolasers. It is required, for example, to produce optical chips that could…
