Of all the stellar events in the universe, supernovae are the crucibles of the heavier elements, the ones on which life as we know it depends. They also leave stunningly beautiful remnants, like the Veil Nebula, of which there is a recently-enhanced image from the Hubble Space Telescope. Pic and story at C|Net.
The Hubble Space Telescope has revealed the cosmos in stunning detail over its three decades of service. The telescope's view of the Veil Nebula -- a remnant of a supernova -- has gotten a makeover that reveals previously unseen details of the structure.
The Veil is 2,100 light-years from Earth in the constellation Cygnus, the Swan. It was the subject of a 2015 Hubble image release, but the new look highlights what the European Space Agency (ESA) described as "the nebula's delicate threads and filaments of ionized gas" in a statement this week.
The changes between the two image versions may seem subtle at first, but the delight is in the details. "The new post-processing methods have further enhanced details of emissions from doubly ionized oxygen (seen here in blues), ionized hydrogen, and ionized nitrogen (seen here in reds)," ESA said.
For those who dislike reading, a direct link to the picture.

Remember, kids: "Recently enhanced" means B&W pictures that were prettied up by a graphic designer to get more funding for scientists to spend on hookers and blow.

I understand that you just make strange jokes, yet you could realize that you writing those strange jokes on your computer and sending them over internet is only possible due to scientists got more funding (and due to your really bad taste at the end).
BTW Hubble used five different filters [nasa.gov] to get data for the picture.

While it's true that it's a long standing tradition to colorize images I wouldn't exactly call this deep fake. They have been colorizing images way before the deep fake and the photoshopping. Still pretty picture but at the same time who is to say what that really is or what it will look like if we ever get there in person.

The telescopes are designed to capture things that the naked eye cannot see. The information they are colorizing from already includes things that they eye cannot see, and the colorization takes it further away from reality. Its a pretty picture, but if you were in a spaceship looking out your window, it does not look like that.

Ah.. you're an aspiring reporter for OAN I see... Maybe instead of hookers try iPhones and meth. You need to strike that delicate balance between being believable and being relatable to your audience.

Has anyone exlained how gravity forms filaments like that? It looks more like this:

Gases/plasmas subjected to self-gravity experience the Jeans instability, which leads to structure formation. https://en.wikipedia.org/wiki/Jeans_instability. [wikipedia.org]
But I don't think that's visible here. I *believe* what you're seeing are shocks/caustics due to chunks of supersonic gas (actually plasma).

correction: the yellow-green stuff does seem to be the result of the Jeans instability.
the blue stuff looks like shocks/caustics.
