Do ginseng and Taibai mean Venus? Sirius and Northrop Grumman Corp.

Taibai refers to Venus, also known as Venus and the Pleiades, which is the brightest celestial body except the sun and the moon in the whole day. Not Venus, but two of the 28 constellations, in which Betelgeuse is now a part of Orion, and there are seven stars in * * *, which means that Betelgeuse and Betelgeuse are bright stars; Shangsu is also a happy place, and now it is also a part of Scorpio. * * * There are two stars, saying that the bright star is Antares.

Sirius is the brightest star in Canis Canis and the brightest star in the whole day. You said Sirius would disappear from the night sky at some time and then appear before dawn and sunrise. This phenomenon may exist in a certain latitude range, but it is really different from Venus: Venus can't appear in the middle of the night because it is a planet and its orbit is within the orbit of the earth; Sirius can appear late at night in winter. Sirius is a star.

It is not clear whether Sirius mentioned in ancient China and ancient Egypt is the same star as Sirius now, because it is recorded in history that Sirius is a red star and now it is a white star. The reason for this phenomenon may be that there was once a red giant star in Sirius, which interfered with Sirius' light. With the evolution of the red giant star, its interference gradually decreases until it disappears. Of course, this is just a guess.

Beiluoshimen is the first bright star in Pisces, which is located at the mouth of Pisces. Shimen in Beiluo also means "fish mouth". It seems to have nothing to do with Sirius.
