Hubble’s updated Veil Nebula image will take your breath away



The star died of fire and anger.

They trembled and ejected their internal organs out of space. When the star exploded and the violence ended, there was still a group of gorgeous shining star guts.

Such an event is the cause of the Veil Nebula, which is a gossamer that is scattered with the remnants of a larger supernova called the Cygnus ring. About 10,000 years ago, when a star with a mass 20 times the mass of the sun When it enters a supernova, it is created.

If you like space photos (and which science lover doesn’t like it?), you may have already seen it-the Hubble Space Telescope released a spectacular image in 2015, which was taken with a wide-angle camera 3 instrument, rainbow Silk traverses the darkness of space.

Now, researchers have used new technology to reprocess these data to dig out more details.

The Veil Nebula is located at a distance of about 2,100 light-years and spans about 110 light-years. It is believed to be shaped by the powerful stellar winds that emanated before the star exploded.

The wind blows into the gas that the dying star has ejected, hollowing out the cavity. When the supernova shock wave pushes into the area, it interacts with the cavity wall, causing the gas in the cavity to vibrate and excite energy, thereby forming a complex veil-like structure.

Such images are not only spectacles, they can also help astronomers understand these interstellar processes. For example, here, different gases emit light with slightly different wavelengths, and the colors of these lights have been color-coded-blue represents double-ionized oxygen, and red represents ionized hydrogen and nitrogen ions.

Green gases are not disturbed by shock waves like blue, so they have time to cool and diffuse into a more fluffy form of chaos.

Since the nebula is still expanding, studying these filaments and their composition can help us better understand the structure of the cloud and how the shock waves of the supernova interact with it. You can also compare such images taken at different times to see the speed of the shock wave.

Hubble’s observations in 2015 were compared with images of the nebula taken in 1997-see the video above-and scientists were able to calculate that it was expanding at a rate of 1.5 million kilometers (932,000 miles) per hour. The diameter of the earth for reference is 12,742 kilometers.

Eventually, the remains of young and hot stars that died in this dramatic way will all be blown away and dispersed in the interstellar medium. Even for stars, everything must come to an end.
