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…
But not all magnetospheres are created equal: Venus and Mars do not have magnetospheres at all, while the other planets — and one moon — have ones that are…
Terahertz radiation has a wide range of uses and can occur in everything from radio astronomy to medicine. The term refers to the electromagnetic waves whose…
Seeking a better way to capture radioactive iodides in spent nuclear reactor fuel, Rutgers-New Brunswick scientists have developed an extremely efficient…
Molecules rotate in the range of picoseconds (10-12 s), their atoms vibrate in the range of femtoseconds (10?15 s), and the electrons move in the range of…
Now a team of scientists led by the University of Southampton has moved a step closer to understanding these mysterious cosmic phenomena – known as…
The search for new and brighter radiation sources is an enduring quest in science and technology [1,2]. While there are many sources across the entire…
Of particular importance for potential applications is the ability to manipulate the acceleration process, known as a swing-by maneuver from space travel, with…
Everyone knows this problem: a friend sends a low-resolution image of last weekend´s hike to your smartphone, but when you save the picture of the beautiful…
Multisensor arrays for determining gas mixture composition are currently being developed. These are monitoring systems incorporating multiple sensors that…
Already in 1842, British mathematician Samuel Earnshaw proved that there is no stable configuration of levitating permanent magnets. If one magnet is levitated…
The research was led by a Trinity College Dublin team comprising PhD candidate in the School of Natural Sciences, Lauren Mc Keown, and Dr Mary Bourke, along…
Though the Webb telescope will focus on stars and galaxies approximately 13.5 billion light-years away, its sight goes through a similar process as you would…
Using the NASA/ESA Hubble Space Telescope, astronomers have discovered that the brightest galaxies within galaxy clusters “wobble” relative to the cluster's…
Pulsed laser irradiation on the gold-coated silver nanoparticles (Ag@Au NPs) provided a solution to the problem. When Ag@Au NPs are irradiated with a pulse…
