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 new research, which is published online today [17 December] in the Monthly Notices of the Royal Astronomical Society, is part of the RMS Survey, which was…
The team will test the predictions of current theories of gravity, including Einstein's theory of General Relativity, The funding is provided in the form of a…
Ultrasound-stimulated microbubbles have been showing promise in recent years as a non-invasive way to break up dangerous blood clots. But though many…
This may have practical significance in the control of nanoscale friction. The results have been published in the scientific journal Nature Materials. Friction is often seen as an adverse phenomenon that leads to wear and causes energy loss. Conversely, however, too little friction can be a disadvantage as well – for example, running on an icy surface or driving on a wet road….
The scientists observed twisting patterns in the polarization of the cosmic microwave background—light that last interacted with matter very early in the…
In the scenario of Paulo Freire and Thomas Tauris, a massive white dwarf star accretes matter and angular momentum from a normal companion star and grows…
Europa is already thought to harbour a liquid ocean beneath its icy crust, making the moon one of the main targets in the search for habitable worlds away from…
