In a distant point… the most expensive space observatory achieves a scientific result

nebula The stranger is located in the Milky Way, about 2,000 light-years away Solar systemrelating Cloud A gas and dust giant produced by a star, as it ejects some of its matter when it descends, and contains a lot of gas and little dust.

And at the center of the nebula remains the heart of this star, which is called a white dwarf, and is a very hot and very small star, difficult to see directly, but its existence can be guessed thanks to the orange rings that surround it, which are the traces of the substance he emitted.

It is assumed that the fate of our sun will be similar in a few billion years, as will the vast majority of stars.

But unlike the sun, which will set by itself, the white dwarf at the heart of the Southern Ring Nebula isn’t alone. It was known until now that it has one star "A mate"It’s easier to spot than a white dwarf because it’s still very young.

This companion star is the one that appears brightest in the center of the dust disk in images taken by the James Webb telescope, which has been 1.5 million kilometers from Earth since last summer.

But this stellar binary, familiar to the Milky Way, did not provide a justification for the structure "atypical" For the nebula, as explained by Philippe Amram, of the Marseille Astrophysics Laboratory, who is one of the authors of the study published on Thursday in the journal "Nature astronomy" Includes a detailed explanation of the telescope’s most recent observations.

The National Center for Scientific Research researcher added that scientists have sought, since the discovery of the southern ring nebula by astronomer John Herschel in 1835, to know the cause of "Its strange non-spherical shape".

James Webb’s observations help to clarify this mystery, as instruments of telescopes equipped with vision at the infrared level, a wavelength invisible to the human eye, have provided evidence of the presence of at least two other stars inside of the nebula.

These two discovered stars lie at the center of the nebula, which spans a diameter 1,500 times the distance from the Sun to Pluto. They are further away from the white dwarf than the companion star, but the four stars are usually close enough to each other to interact.

This falls nebula The stranger is located in the Milky Way, about 2,000 light-years away Solar systemrelating Cloud A gas and dust giant produced by a star, as it ejects some of its matter when it descends, and contains a lot of gas and little dust.

And at the center of the nebula remains the heart of this star, which is called a white dwarf, and is a very hot and very small star, difficult to see directly, but its existence can be guessed thanks to the orange rings that surround it, which are the traces of the substance he emitted.

It is assumed that the fate of our sun will be similar in a few billion years, as will the vast majority of stars.

But unlike the sun, which will set by itself, the white dwarf at the heart of the Southern Ring Nebula isn’t alone. It was known until now that it has a “companion” star, which is easier to spot than a white dwarf because it’s still in its infancy.

This companion star is the one that appears brightest in the center of the dust disk in images taken by the James Webb telescope, which has been 1.5 million kilometers from Earth since last summer.

However, this familiar stellar binary in the Milky Way galaxy did not provide a justification for the nebula’s “atypical” structure, as explained by Philippe Amram, of the Marseille Astrophysical Laboratory, who is one of the authors of the study published Thursday in the journal ” Nature Astronomy” and includes a detailed explanation of what the telescope last observed.

Since the discovery of the southern ring nebula by astronomer John Herschel in 1835, the National Center for Scientific Research researcher added that scientists had sought to know why it was “strangely non-spherical in shape.”

James Webb’s observations help to clarify this mystery, as instruments of telescopes equipped with vision at the infrared level, a wavelength invisible to the human eye, have provided evidence of the presence of at least two other stars inside of the nebula.

These two discovered stars lie at the center of the nebula, which spans a diameter 1,500 times the distance from the Sun to Pluto. They are further away from the white dwarf than the companion star, but the four stars are usually close enough to each other to interact.
