A wonderful Veil

This beautiful image of the Veil Nebula was acquired with the Hubble Space Telescope some time ago. Now it has been reprocessed with new techniques, which bring to light some very fine details in the delicate ionized gas strands of the nebula.

To obtain such a striking image, Hubble observations were taken using five different filters. Moreover, a clever method of post processing has highlighted the areas of doubly ionized oxygen (in blue), of ionized hydrogen, and of ionized nitrogen (here in red). The Veil Nebula is located about two thousand one hundred light years from Earth, relatively close in astronomical terms. Actually, this image shows just a detail. The nebula was formed by the supernova outbreak of a star about 20 times the size of the Sun, about ten thousand years ago. The remains of the exploded star created this scene of surprising beauty.

It comes to mind now, while much of the world celebrates the mysteries of death and rebirth contained in Easter (or at least reflects on them, on the wave of the tradition that however, it brings thought stimuli valid for everyone). Now I can't help but think of certain deads which bear much fruit in the cosmos. What seemed lost, from a different point of view, is a new gain. We need to broaden our vision. It is tiring, it is a real job. Yes, the star really die, but what is born of it is an unexpected flowering.

What can help us remember this? I can just suggest that beauty must have its part, beauty must enter into it, in some way. Like the beauty of this nebula. The enthusiasm of dedication is incomparable to the enthusiasm of beauty, Luigi Giussani said.

The beauty of the cosmos is for something. To be seen, we might venture. For an enthusiasm, ultimately. A crazy thought, perhaps? Who knows. But a happy thought, all things considered. Wish you a Happy Easter.
