AG Carinae: Star on the edge of destruction

This star named AG Carinae has existed in our Milky Way for millions of years and is about 20,000 light-years away. It is estimated that its mass is 70 times that of our sun, and it glows with the dazzling rays of one million suns.

NASA’s Hubble Space Telescope has discovered a bright “famous star”, one of the brightest stars in our galaxy, surrounded by a halo of hot gas and dust, and on the verge of extinction. It has existed for millions of years and is 20,000 light-years away from us in our galaxy. It is estimated that its mass is 70 times that of our sun, and it glows with the dazzling rays of one million suns.

The price of his wealth is “living on the edge.” They are a tug-of-war game between gravity and radiation to prevent self-destruction. Hubble’s careful observation revealed the most distinctive feature of AG Carinae: the filamentous structure of the form and twisted bubbles. These structures are clusters of dust illuminated by star clusters. reflected light.

The figures in the shape of the are most prominent on the left and in the background, as dense clusters of dust formed by stellar winds. The photo was taken under visible light and ultraviolet light. Ultraviolet light provides a clear image of the filamentous dust structure extending to the star. The Hubble Telescope is very suitable for observation in ultraviolet light, because this wavelength range can only be seen in giant stars that were formed by one or more huge eruptions about 10,000 years ago.

The outer layer of the star was thrown into space like a boiling kettle torn from the lid. The ejected material is about ten times the mass of our sun. Many other AG Carinae Blu-ray variables are still unstable. She experienced smaller flares, but not as large as the flares that produced the current fog.

Although AG Carinae now sleeps like a superfast star, it continues to emit scorching radiation. When the air current collides with the slowly moving outer nebula, the powerful stellar wind (stream of charged particles) will continue to shape the old nebula and form a complex structure.
