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…
Yale University astronomers, using a new type of telescope made by stitching together telephoto lenses, recently discovered seven celestial surprises while…
This concept calls for running optical fiber to a distribution point that can be flexibly installed relatively close to the customer premise. The existing…
Physicists in Innsbruck have now realized quasiparticles in a quantum system and observed quantum mechanical entanglement propagation in a many-body system….
The findings are consistent with observations that Earth-sized planets appear to be very common in other star systems. Although heat can be a destructive force…
The findings by an international team of astronomers led by Laura Spitler from the Max Planck Institute for Radio Astronomy in Bonn, Germany are published on…
Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground,…
“Our model indicates that this vast shell of gas and dust has a more complex origin than is generally assumed,” said Thomas Madura, a NASA Postdoctoral Program…
When a superconductor is exposed to a magnetic field, a current on its surface appears which creates a counter field that cancels the magnetic field inside the…
Light from tiny galaxies more than 13 billion years ago played a larger role than previously thought in creating the conditions in the universe as we know it…
Physical analog models simulate geologic structures in laboratory settings so that the developmental sequence of various phenomena can be studied as they occur.
An observatory run by the University of Utah found a “hotspot” beneath the Big Dipper emitting a disproportionate number of the highest-energy cosmic rays. The…
In the drive to get small, Robert Wolkow and his lab at the University of Alberta are taking giant steps forward.
Secure data communication, quantum computation, and sensing devices benefit from light sources, which emit only one photon at a time. These light sources…
Wieso verbindet man die Mobilfunkmasten untereinander nicht mit Kabeln? Grund dafür ist die Tatsache, dass Datenübertragung über weite Strecken bei…
Determining the age of stars has long been a challenge for astronomers. In experiments published in the journal Science, researchers at KU Leuven's Institute…
