They capture a giant star on the verge of destruction

The star called AG CarinaeIt has an extended layer of gas and dust surrounding it with a width of about five light years, equivalent to the distance from Earth to the nearest star outside the sun, Proxima CentauriThe scholars added, according to the Europa Press cable.

The colossal structure was created from one or more gigantic eruptions about 10,000 years ago. They explained that the outer layers of the star flew into space, like a boiling kettle peeling off its cap.

They added that the ejected matter is equal to about 10 times the mass of our sun, according to NASA.


These eruptions are the typical life of a rare breed of star called the luminous blue variant.

It is among the largest and brightest stars known, living only a few million years, compared to about 10 billion years of the Sun’s life.

AG Carinae is a few million years old and resides 20,000 light years away inside our Milky Way galaxy.

These giants are stars in their extremes, and they are very different from regular stars like our Sun. In fact, AG Carinae is estimated to be 70 times the mass of the sun and shines as much as a million suns.

“I like studying these types of stars because I’m intrigued by their instability,” said Kerstin Weiss, an expert on bright blue variants at the Ruhr University in Bochum, Germany.

Large explosions such as the one that spawned the nebula would occur once or twice during the life of a bright blue variable.

Due to their formidable shapes and extreme temperatures, bright blue variable stars like AG Carinae are in a constant battle to preserve stability.

Although AG Carinae is now sleeping, like a superfast star, it continues to emit fiery radiation and strong stellar winds (streams of charged particles).

This flow continues to form the ancient nebula, carving out complex structures as flowing gas hits the slow-moving outer nebula.

Wind travels at a speed of one million kilometers per hour, ten times faster than an expanding nebula.

They added that the red substance that can be seen is glowing hydrogen gas mixed with nitrogen gas. The blurred red material in the upper left indicates where the winds passed through a faint region of material and carried it into space.

The most prominent distinguishing features of blue are the tadpole-shaped filamentous structures and twisted bubbles.

A sharp view of the Hubble Telescope reveals these delicate-looking structures in great detail. The image is captured with visible and ultraviolet light, providing a clearer view of the filamentous dust structures that extend all the way to the star.

Massive stars such as AG Carinae are important to astronomers due to their far-reaching effects on their surroundings.

The largest program in Hubble’s history, the Young Stars Ultraviolet Legacy Library as standard, studies the ultraviolet light of young stars and how they shape their surroundings.

Luminous blue variable stars are rare. Fewer than 50 galaxies are known between galaxies in our home group of neighboring galaxies.

The researchers explained that they are stars that spend tens of thousands of years in this stage, but – nevertheless – this time is a “blink of an eye in cosmic time.”
