An anomalous relativistic emission arising from the intense interaction of lasers with plasma mirrors
Interactions between intense laser pulses and plasma mirrors have been the focus of several recent physics studies due to the interesting effects they produce. Experiments have revealed that these interactions can generate a non-linear physical proce.....»»
Real-time Linux is officially part of the kernel after decades of debate
Now you can run your space laser or audio production without specialty patches. Enlarge / Cutting metal with lasers is hard, but even harder when you don't know the worst-case timings of your code. (credit: Getty Images).....»»
How humans are affecting the Northern Hemisphere"s wind patterns
The summer of 2024 was the hottest on record and, unfortunately, this came as no surprise. Summers have been getting hotter and drier around the world, including in the Northern Hemisphere, leading to intense droughts and heat waves in North America.....»»
Webb Telescope provides another look into galactic collisions
An interaction between an elliptical galaxy and a spiral galaxy, collectively known as Arp 107, seems to have given the spiral a happier outlook thanks to the two bright "eyes" and the wide semicircular "smile." The region has been observed before in.....»»
There are plenty of uses for powerful lasers in space. But where should we put them?
Is it time for space lasers yet? Almost......»»
Tracking plasma progression in a picosecond: Physicists develop ultra-fast laser method to study high-density plasmas
In a few picoseconds (trillionths of a second), a small, thin piece of copper momentarily becomes dense plasma, specifically a state called warm dense matter, warm being a relative term—the metal is nearly 200,000 degrees Fahrenheit. With the short.....»»
