NASA first released an image of the Veil Hubble Nebula in 2015. And now, six years later, scientists have revised and edited it to make it even more impressive. Thanks to the new set of filters applied, the photo now shows a more realistic and detailed view of the Veil Nebula than before, and it really is.
The Veil Nebula is a popular theme for Hubble images, as NASA explains. But image processing methods have been improving since 2015, so scientists have decided to give it a fresh look. The new version of the image reveals small details of the nebula filaments and ionized gas filaments.
NASA writes that the scientists used five different filters to create this image, made with a wide-format Hubble 3 camera. The blue parts of the nebula are emissions of double ionized oxygen, and the red – ionized hydrogen and ionized nitrogen. Take a look at the old and new versions of the image so you can compare them:
“The Veil Nebula lies about 2,100 light-years from Earth in the constellation Cygnus,” NASA wrote. While this does sound like a lot, the truth is that it is actually relatively close to us astronomically. And it was only a small part of this beautiful nebula that was captured in the image.
“The Veil Nebula is a visible part of the neighboring Swan Loop, a supernova remnant formed about 10,000 years ago by the death of a massive star. The star of the Veil Nebula, 20 times the mass of the Sun, lived fast and died young, ending her life with a cataclysmic release of energy.
During his 31-year career, Hubble has made many impressive images. And this is not the first time NASA has viewed an old image taken with this telescope. As image processing technology becomes more sophisticated, it allows you to see even familiar space objects in a new, more detailed light. And it’s always an impressive experience.[via Digital Trends, image credits: ESA/Hubble & NASA, Z. Levay]
