Hubble approached AG Carinae until it was successful to reveal the dual nature of the giant star. It has another name, namely HD 94910, an old giant star.
NASA released these observations and determined that AG Carinae was the 31st Hubble target. As of April 2021, this will be in the spotlight from a new perspective.
Some of these images were captured using the Wide Field Planetary Camera 2 or WFPC2 and the Wide Field Camera 3 or WFC3.
Use five filters with different colors for each monochromatic image. With separate exposure of the ultraviolet spectrum region. The image shows an enormous majestic light.

Hubble Telescope Approaches AG Carinae In Celebration of 31
It is one of the brightest stars in the Milky Way galaxy. Even astronomers consider this object as a celebrity star because its shining light steals the attention.
His discovery in the constellation Carinae in the southern sky. It ranges from 20,000 light years, with an estimated age of between five and six years.
This giant star is included in the Luminous Blue Variable. Because of its massive evolution in turning into a Wolf Rayet star. Even the brightness level of this star is tens of thousands to several million brighter than the Sun.
So that the star automatically pulls and pulls. Between the process of gravity and radiation to slow down self-destruction.
So Important Discovery
Hubble’s approach to AG Carinae is an incident that is caught and is an important matter. Because of its influence on the universe which is quite wide.
So ULLYESS or Ultraviolet Legacy Library of Young Stars as Essential Standards began to study it. Regarding light from the ultraviolet rays of young stars as well as the process of formation of their environment.
Because in a Luminous Blue Star Variable it is very rare. Even less than fifty among the galaxies in our local cluster of neighboring galaxies.
The phases take up tens of thousands of years and in a flash of cosmic time. Estimates will end their lives in a titanic supernova explosion. So the universe will get elements that are heavier than iron outside, which is interesting.

Struktur AG Carinae
Hubble’s approach to AG Carinae gave the result that the spectacular nebula came from a past star. When an explosion occurs and the various materials are ejected automatically.
The width of the nebula reaches 5 light years. While the distance from the nearest star to Earth named Alpha Centauri which is around 10,000 years old.
Because the nebula is shaped like a ring, it turns out to be a hollow shell. Derived from gas and dust as constituents.
While in the middle it is clean, this happens when the wind from the moving star reaches 200 km / s, it is normal if the conditions are clean.
The development of this observation into the third year. After the first time in 1994, 2014, and the last time this year 2021.
Layer Structure
Hubble’s approach to AG Carinae shows that the massive structure came from a giant explosion. While the outer layer was thrown into outer space.
If we think of it as a boiling teapot that comes off the lid. The material that managed to escape was ten times the mass of the Sun, very hot.
Because of this quiet, yet ferocious structure. Reportedly this giant star has 70 times larger than the Sun. While the light shines brilliantly dazzling more than a million suns. Enchanting, but unstable in its activities.
Currently they are in a state of silence, but they continue to emit radiation. Burning and strong stellar winds in streams of charged particles formed the ancient nebula.
Image Analysis
We’ll include this image from Hubble approaching AG Carinae. Well, to understand the picture, we will reply more deeply. Because the structure comes from past stellar explosion material. Then in the shell is gas and dust.
We can see for ourselves in the color part is the emission of hydrogen and ionized nitrogen. As for the image with a contrasting blue color is the distribution of dust.
So from here the starlight shines and can be reflected. Astronomers even call it celebrity star because the contrast is very successful in stealing the attention of anyone who observes it.
Hubble’s approach to AG Carinae is a rare and interesting study. If later there will be more interesting activities, then this is really something new from the study of the universe. (R10/HR Online)
