Because electrons
scatter polarized light more than non-polarized light, that observation will give the scientists a bead on what the electrons are doing, and by extension, what the solar wind is doing — how fast it flows, how hot it is and even where it comes from.
Not exact matches
Light can become
polarized by
scattering off surfaces, such as a car or pond.
In the case of the cosmic microwave background,
light scattered off particles called electrons to become slightly
polarized.
We see
polarized light in everyday life: At the beach on a hazy day,
polarized sunglasses filter out
polarized glare from water -
scattered photons, so that we can better see our surroundings.
Like
polarized light (which vibrates in one direction and is produced by the
scattering of visible
light off the surface of the ocean, for example), the
polarized «B - mode» microwaves the scientists discovered were produced when CMB radiation from the early universe
scattered off electrons 380,000 years after the Big Bang, when the cosmos cooled enough to allow protons and electrons to combine into atoms.
We observed and spatially resolved the disk around the ~ 10 Myr old protoplanetary disk HD 100453 in
polarized scattered light with SPHERE / VLT at optical and near - infrared wavelengths, reaching an angular resolution of ~ 0.02», and an inner working angle of ~ 0.09».
We detect
polarized scattered light up to ~ 0.42» (~ 48 au) and detect a cavity, a rim with azimuthal brightness variations at an inclination of 38 degrees, two shadows and two symmetric spiral arms.
We observed and spatially resolved the disk around the ~ 10 Myr old protoplanetary disk HD 100453 in
polarized scattered light with SPHERE / VLT at optical and near - infrared wavelengths, reaching an angular resolution of ~ 0.02», and an inner working angle... ▽ More Understanding the diversity of planets requires to study the morphology and the physical conditions in the protoplanetary disks in which they form.
The
light from the front edge of the disk is strongly
polarized as it
scatters towards us.
Moreover, it is found that
polarized reflectances obtained at the shorter wavelengths (0.41 and 0.55 µm) are significantly less sensitive to the contribution of the ocean's upwelling
light than total reflectance measurements, providing a natural tool for the separation between the estimation of oceanic and atmospheric
scattering properties.
