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…
Does the Milky Way look fat in this picture? Has Andromeda been taking skinny selfies? It turns out the way some astrophysicists have been studying our galaxy…
Over the vast, empty reaches of interstellar space, countless small molecules tumble quietly though the cold vacuum. Forged in the fusion furnaces of ancient…
The Cheshire Cat featured in Lewis Caroll's novel “Alice in Wonderland” is a remarkable creature: it disappears, leaving its grin behind. Can an object be…

Acoustic measurements are often subject to unwanted background noise, which compromise the validity of noise measurements. By using a statistical prediction model the invention automatically identifies the disturbed sections and then systematically suppresses these areas in the level detection. In contrast to the frequently used method of percentile ranks the inventive method is not fixed to fixed proportions of background noise.
Data transmission over long distances usually utilizes optical techniques via glass fibres – this ensures high speed transmission combined with low power…
This invention for the examination of metallic nanoparticles in a sample exploits the plasmonic properties of metals. A metal tip with a Raman-active coating is used as a sensor to converge on the particle to be examined. The tip and particle form a resonator structure in the case of a metallic nanoparticle. This resonator structure causes the Raman signal belonging to the sensor coating to be amplified and thus enables the metallic particle to be identified under normal conditions.
Rubber duckie has a collar! At least this is what the surface structures of comet 67P/Churyumov-Gerasimenko look like in new images of taken by Rosetta’s…
The three planets, known as HD 189733b, HD 209458b, and WASP-12b, are between 60 and 900 light-years away from Earth and were thought to be ideal candidates…
Astronomers using the NASA/ESA Hubble Space Telescope have mapped the mass within a galaxy cluster more precisely than ever before. Created using observations…
