How MIRI became Webb"s coolest instrument
The NASA/ESA/CSA James Webb Space Telescope is widely referred to as the successor to the NASA/ESA Hubble Space Telescope. In reality, it is the successor to a lot more than that. With the inclusion of the Mid-InfraRed Instrument (MIRI), Webb also be.....»»
Artificial intelligence deciphers detector "clouds" to accelerate materials research
X-rays can be used like a superfast, atomic-resolution camera, and if researchers shoot a pair of X-ray pulses just moments apart, they get atomic-resolution snapshots of a system at two points in time. Comparing these snapshots shows how a material.....»»
