Quantum scale sensors used to measure planetary scale magnetic fields

Quantum scale sensors used to measure planetary scale magnetic fields

Magnetic fields are everywhere in our solar system. They originate from the sun, planets, and moons, and are carried throughout interplanetary space by solar wind. This is precisely why magnetometers—devices used to measure magnetic fields—are flown on almost all missions in space to benefit the Earth, planetary, and heliophysics science communities, and ultimately enrich knowledge…

Metalenses phase characterization by multi-distance phase retrieval

Metalenses phase characterization by multi-distance phase retrieval

Metalens is a kind of optical metasurface composed of metaatoms for manipulating incoming light’s amplitude, phase, and polarization. Unlike traditional refractive lenses, metalens can modulate the wavefront from plane to spherical at an interface. It has garnered widespread attention due to its novel physical properties and promising potential applications. Metalens is a kind of optical metasurface…

Elliptical orbits could be essential to the habitability of rocky planets

Elliptical orbits could be essential to the habitability of rocky planets

A seismic shift occurred in astronomy during the Scientific Revolution, beginning with 16th-century polymath Copernicus and his proposal that the Earth revolved around the sun. By the 17th century, famed engineer and astronomer Galileo Galilei refined Copernicus’ heliocentric model using observations made with telescopes he built himself. However, it was not until Kepler’s observations that…

Work emails, calls on golf course worsen performance, study finds

Checking your work-related emails or taking business calls while playing golf could prevent you from hitting that elusive eagle or birdie. This is according to a group of researchers from the Department of Information Science at Stellenbosch University (SU). Checking your work-related emails or taking business calls while playing golf could prevent you from hitting that…
