Hubble's dead star image is so magical it feels like fiction

 An unpublished photo showing the Veil Nebula released by NASA and the European Space Agency (ESA) and captured by the Hubble telescope impressed by the beauty and grandeur of the record. Revealing the “trail” of the death of a gigantic star that occurred about 10,000 years ago, the photo shows the veil located 2,100 light-years from Earth, and it also ends up offering the dimension and beauty of space itself: to have an idea of ​​the distance, each light year is equivalent to about 9.5 trillion kilometers. 

The Veil Nebula photo is not unpublished, as a first publication of the image was released by the US space agency in 2015, but the new photo was published as of further data processing generated by Hubble to achieve a more detailed and broader view of the recorded gas waves. "To create this color image, we used five different filters in observations from the Wide Field Camera 3," NASA explained in a statement about the new image.

To give the dimension of the event from which the nebula arose, NASA had to resort to literary tones in its note. According to the text, the star "lived fast and died young" in an "energy release cataclysm" at the end of the star's life. "Despite this stellar violence, shock waves and supernova debris carved out the delicate ionized gas tracery of the Veil Nebula, creating a scene of startling astronomical beauty." "Neighbor" constellation Anyone who thinks that the many trillions of kilometers separating the Earth from the Veil photographed is mistaken by those who actually study the dimensions of the universe: according to NASA, the constellation of the Swan is, in astronomical proportions, practically neighboring the Solar System. “The Veil Nebula is about 2,100 light-years from Earth, in the constellation Cygnus (the swan), making it a relatively close neighbor in astronomical terms,” says the text, which still confirms that only a part of the nebula can be seen in the image
