What does cx330 correspond to?

The net name cx330 means unique and lonely.

In 2009, NASA's Chandra X-ray telescope first discovered this star named CX330. This star was born/kloc-0.0 million years ago, not even as long as human history. But it is experiencing a spurt of growth. With its rapid growth, the material ejected from the inside is entering the surrounding gas and dust.

CX330 stars grow rapidly in the desert space of the Milky Way far away from any other known celestial bodies. Without stars as neighbors and planets as companions, it is lonely and rare. This young star, which was born only 654.38 billion years ago, was called "the loneliest star in the universe" by NASA.

Observation of stars:

Human observation of stars has a long history. The ancient Egyptians predicted the Nile flood the moment Sirius appeared on the eastern horizon. The Shang Dynasty in China set up special officials to observe the appearance of the Great Eastern Mars (Antares) and determine the start time of the year. In the process of observation, the Song Dynasty discovered the supernova of Taurus-the celestial official guest star. Sailors in the Ming Dynasty used the navigation of nine planets to judge their direction.

Many ancient astronomers believed that stars were fixed on the eternal celestial sphere and would never change. Traditionally, astronomers combine the stars into constellations or stars and use them to determine the motion of planets in the sky.

The cycle of the sun's movement under the starry sky background is used to create calendars and guide agricultural time. The Gregorian calendar, which is used almost all over the world now, is based on the nearest star, the sun.
