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…
Visible light is the part of the electromagnetic spectrum that is most important to our everyday perception. The fact that our environment is colored and that…

High-performance LEDs typically have a lens positioned right on top of the emitting surface. With this lens it is possible to…
While astronomers have found indirect evidence of these disturbances, the waves have so far eluded direct detection. Ground-based observatories designed to…
In a world first, the team has been able to look at a distant black hole and resolve the area where its jets are launched from. This is the first empirical…
The point of no return: In astronomy, it’s known as a black hole — a region in space where the pull of gravity is so strong that nothing, not even light, can…
For the first time, they have measured the black hole's “point of no return” – the closest distance that matter can approach before being irretrievably pulled…
Using a method called reconstructive speckle imaging, the researchers took the sharpest ground-based snapshots ever obtained of Pluto and Charon in visible…
The research findings appear in the September issue of Physical Review Letters. “Black hole bombs and photon mass bounds” is co-authored by Emanuele Berti, UM…
A novel B1-mapping technique (B1-TRAP) is presented, which offers a good compromise with respect to speed, robustness and accuracy.
