An image of an impressive butterfly in the shape of a butterfly in the Milky Way was taken by the European Southern Observatory (ESO) telescope.
The impressive planetary nebula, known as NGC 2899, appears to float and flicker across the sky in this pristine image from the very large ESO telescope in Chile.
A planetary nebula is created when a star does not have enough fuel to burn and blows its outer layers of gas into space.
NGC 2899 has never before been recorded in such detail, revealing the weak outer edges of an expandable gas shell glowing over the background stars.
The blue parts of the ‘butterfly̵7;, located at a distance of up to 6,500 light-years, consist of oxygen gas, and the surrounding reddish hue along the edge – hydrogen.

This highly detailed image of the planetary nebula NGC 2899 was taken using the FORS instrument on a very large ESO telescope in northern Chile. This object has never been depicted in such vivid detail before
“This object has never been depicted in such striking detail before, even the faint outer edges of the planetary nebula glow above the background stars,” the ESO said in a statement.
Despite their name, planetary nebulae – shells of gas and dust that have been ejected from a dying star – have nothing to do with planets.
They are formed when ancient stars, which are up to six times the mass of our Sun, reach the end of their lives, collapse and blow out expanding shells of gas, rich in heavy elements.
Intense ultraviolet radiation also illuminates these moving shells, causing them to glow brightly for thousands of years.
After all, planetary nebulae are slowly spreading in space, which means that they are relatively short-lived and rare – there are about 1,500 people in the galaxy, according to the Harvard-Smithsonian Center for Astrophysics.
NGC 2899, discovered by English astronomer John Herschel in 1835, is located somewhere between 3,000 and 6,500 light-years away in the southern constellation of Veli.
The large volume of NGC 2899 gas extends up to a maximum of two light years from its center and reaches 18,000 degrees Fahrenheit or 10,000 degrees Celsius.

Such high temperatures are due to the large amount of radiation from the parent star of the nebula, due to which the hydrogen gas in the nebula glows a reddish halo around the oxygen gas, blue.
NGC 2899 has two central stars, which are believed to give it an almost symmetrical appearance.
After one star has reached the end of its life and discarded its outer layers, another star interferes with the flow of gas, forming a bipolar form resembling a butterfly.
ESO notes that only about 10-20 percent of planetary nebulae exhibit this type of bipolar form.
Astronomers were able to capture this image using the FORS (FOcal Reducer and Low Dispersion Spectrograph) instrument mounted on UT1, one of four 27-foot telescopes that make up the VLT in Chile.
This high-resolution tool was one of the first to be installed on the VLT – which began operating in 1998 – and lags behind other stunning images.
In 2013, FORS returned the image of a unique green-colored unique nebula, reminiscent of a slimmer ghost from the 1984 film about ghosts.
The glowing green planetary nebula IC 1295, which surrounds a dim and dying star. It is located about 3300 light years in the constellation Scatum (Shield).
The planetary nebula IC 1295 appeared around a dim and dying star located about 3,300 light-years in the constellation of the Scrotum.
He also had previously taken a shot The Omega Nebula, located about 6,500 light-years in the constellation Sagittarius, with a dusty pink center.
FORS was used to study in-depth the physics behind the formation of complex planetary nebulae.
He also facilitated the observation of light from a gravitational wave source and investigated the first known interstellar asteroid.
The asteroid, which its discoverers called “Oumaamua”, is up to a quarter (400 meters) long and strongly elongated – probably 10 times longer than wide.
VERY LARGE TELESCOPE – POSSIBLE TOOL INSTRUMENT
The European Southern Observatory (ESO) has built the most powerful telescope ever made in the Atacama Desert in northern Chile.
It is called a very large telescope (VLT) and is widely considered one of the most modern optical instruments ever manufactured.
It consists of four telescopes whose The main mirrors are 8 pounds (8.2 meters) in diameter.
There are also four mobile auxiliary telescopes with a diameter of six feet (1.8 meters).
Large telescopes are called Antu, Kueyen, Melipal and Yepun.
The European Southern Observatory (ESO) has built the most powerful telescope ever made in the Atacama Desert in northern Chile, and named it the Very Large Telescope (VLT).
On April 1, 1999, the first of the Antu hardware telescopes began routine scientific operations.
Telescopes can work together to form a giant “interferometer”.
This interferometer allows you to filter images for unnecessary obscure objects, and as a result, astronomers can see details 25 times thinner than with individual telescopes.
He was involved in the discovery of the first image of an extrasolar planet, as well as tracking individual stars moving around a supermassive black hole in the center of the Milky Way.
He also watched the afterglow of the most famous Gamma Ray Burst,
