Orbital Parameters of a Cosmic Object: . α - RA, right ascension, if the Greek letter does not appear, á letter will appear. δ - Dec, declination, if the Greek letter does not appear, ä letter will appear.
The use of astronomical symbols for the Sun and Moon dates to antiquity. The forms of the symbols that appear in the original papyrus texts of Greek horoscopes are a circle with one ray for the Sun and a crescent for the Moon. [3] The modern Sun symbol, a circle with a dot (☉), first appeared in Europe in the Renaissance. [3]
Polarimetry is the measurement and interpretation of the polarization of transverse waves, most notably electromagnetic waves, such as radio or light waves. Typically polarimetry is done on electromagnetic waves that have traveled through or have been reflected , refracted or diffracted by some material in order to characterize that object.

The origins of the planetary symbols can be found in the attributes given to classical deities. The Roman planisphere of Bianchini (2nd century, currently in the Louvre, inv. Ma 540) [2] shows the seven planets represented by portraits of the seven corresponding gods, each a bust with a halo and an iconic object or dress, as follows: Mercury has a caduceus and a winged cap; Venus has a ...
The Wisconsin Ultraviolet Photo-Polarimeter Experiment (WUPPE) was a space telescope with a 50cm diameter mirror for spectroscopy and polarimetry in the ultraviolet spectral range. It was used in conjunction with other telescopes on the shuttle missions STS-35 (ASTRO-1 in December 1990) [ 1 ] and STS-67 (ASTRO-2 in March 1995).

IXPE's payload is a set of three identical imaging X-ray polarimetry systems mounted on a common optical bench and co-aligned with the pointing axis of the spacecraft. [1] Each system operates independently for redundancy and comprises a mirror module assembly that focuses X-rays onto a polarization-sensitive imaging detector developed in Italy ...
