Right ascension (abbreviated RA; symbol α) is the angular distance of a particular point measured eastward along the celestial equator from the Sun at the March equinox to the (hour circle of the) point in question above the earth. When paired with declination, these astronomical coordinates specify the location of a point on the celestial sphere in the equatorial coordinate system. An old term, right ascension (Latin: ascensio recta) refers to the ascension, or the point on the celestial equator that rises with any celestial object as seen from Earth's equator, where the celestial equator intersects the horizon at a right angle. It contrasts with oblique ascension, the point on the celestial equator that rises with any celestial object as seen from most latitudes on Earth, where the celestial equator intersects the horizon at an oblique angle.

Why are Astronomers So Bad at Naming Things?
With star names like 2MASS J05551028+0724255, it might seem like astronomers are not so great at naming things. But if you know the code, these names can actually help you find the star in the sky. Hosted by: Reid Reimers ---------- Huge thanks go to the following Patreon supporter for he
