not unique. It has been found that stars of many types are active and havestellar windsanalogousto thesolar wind. The importance and ubiquity of strong stellar winds became apparent only through advances in spaceborneultravioletandX-ray astronomyas well as inradioandinfrared surface-based astronomy....
I used the Optolong L-Pro filter (see myvideo review) when imaging from my light-polluted backyard and was very happy with the results. Whether I used my DSLR camera or a dedicated astronomy camera, the stars were a bit red in the individual exposures. This is very typical of a light ...
for example, is the longest visible wavelength, and violet is the shortest. The main colors of visible light from longest to shortest wavelength can be remembered using the mnemonic ROY G BIV—forRed,Orange,Yellow,Green,Blue,Indigo, andViolet. Other invisible forms of electromagnetic radiation hav...
2. The additional panel d shows qp (see text for the definition). The positive offset is towards the northeast direction. Extended Data Fig. 4 Model using effectively oblate grains. Figure caption is the same as Extended Data Fig. 1, but now with oblate grains. The color scales in panels...
In subject area:Physics and Astronomy Light (Visible Radiation) refers to the portion of solar radiation that our eyes can detect, ranging from red to violet wavelengths. It includes colors like red, orange, yellow, green, blue, and violet, with red light having a wavelength of about 700 nm...
The observation of Doppler shifts in atomic spectral lines is a powerful tool to measure relativemotioninastronomy. Most notably, redshifted light from distantgalaxiesis the primary evidence for the general expansion of theuniverse. There are a host of other astronomical applications, including the ...
It will surely forge additional questions to be addressed in future missions and observatories, such as the next adventure in astronomy—the Nancy Grace Roman Space Telescope. The expansion of our knowledge about the origin of the universe and the detection of planets potentially harboring life will...

Three-dimensional (3D) topological states resemble truly localised, particle-like objects in physical space. Among the richest such structures are 3D skyrmions and hopfions, that realise integer topological numbers in their configuration via homotopic ma
