NASA / ESA’s Hubble Space Telescope has released images of the curtain nebula, originally presented in 2015, this time significantly more details can be seen thanks to new processing techniques.
such as Digital trends Photo reports show the Curtain Nebula, a debris from what NASA describes as one of the best-known supernova remnants. The start of a supernova is expected to be 20 times larger than the Earth’s sun. The entire nebula is 110 light-years long, covering six full moons of the sky when viewed from Earth. It lives in the constellation Cygnus, about 2,100 light-years away.
“The original star of the Curtain Nebula, which is 20 times the mass of the Sun, lived rapidly and died at a young age, ending life with the release of cataclysmic energy. Despite this intensity, shock waves and supernova debris produce the delicate ionization gas of the Veil Nebula, which creates astounding astronomical beauty, ”said the European Space Agency (ESA).
This photograph is a mosaic of six photographs taken by Hubble in a small area of the nebula (about two light years), so it only covers a small part of the entire structure of the nebula. Original images uploaded in 2015 can be viewed below:
While this is fine, it is significantly lower in resolution than new processes, and the color and structure details of the nebula are much less defined. You can see them below:
“Astronomer William Herschel identified the Curtain Nebula in 1784. His work has been followed by Williamna Fleming’s 1904 discovery of the nebula called the Pickering Triangle. (After the director of the Harvard College Observatory where Fleming was working), ”wrote the ESA,“ The Mantle Nebula is best seen in early fall from the Northern Hemisphere. (Early spring in the southern hemisphere) about 8 size, the nebula is not visible to the naked eye. But they can be seen through a telescope or even binoculars under the darkened sky. The nebula filter brightens the Veil and brings out small features.

“To create this colorful image, the observation was captured by Hubble’s Wide Field Camera 3 using five different filters,” the ESA wrote. Of gas emissions from double-ionized oxygen, ionized hydrogen and ionized nitrogen. “
Ionized oxygen is shown in blue in the image above, while ionized hydrogen and nitrogen are shown in red.
Recently, the Curtain Nebula was also part of the Hubble catalog, Cladwell, a collection of astronomical objects photographed by Hubble and amateur astronomers. In the night sky
