The Hubble Space Telescope has continued to demonstrate its irreplaceable importance in the field of astronomical research, bringing back to humanity a unique image showing the brilliant beauty of the Veil Nebula. The Veil Nebula is the remnant of a giant star that exploded in a supernova 10,000 years ago, leaving behind an impressive structure of dust and gas with a fragile, veil-like shape. This is also the feature that creates the name of this nebula.
The star that created the nebula was 20 times more massive than the Sun, and its explosion was so large that it would have been brighter than Venus in Earth’s sky, despite being 2,400 light years away. Over time, the effects of this explosion continued to spread, creating the structure we see today.
Hubble has photographed the Veil Nebula before, most recently in 2015. However, this new image zooms in on a more “subtle” region within the nebula, revealing some interesting new insights. The colors shown in the image also represent the different elements present in the nebula, allowing scientists to trace the region’s unique chemistry.
This image combines photos taken with three different filters from Hubble's Wide Field Camera 3, highlighting the emission from hydrogen, sulfur, and oxygen atoms. The image shows just a small portion of the Veil Nebula. If you wanted to see the entire nebula without a telescope, it would be about the size of six moons placed side by side.
Although this image shows the Veil Nebula at a specific point in time, it could help researchers understand how supernova remnants evolve over decades. Combining the analysis data from this new image with Hubble observations from 1994, scientists expect to find traces of the movement of individual knots and filaments, thereby improving humanity's understanding of this beautiful nebula.
Below are original Hubble images taken in 1994 and 1997, showing details of different parts of the nebula:
