it's not a filter, it's the way the light diffracts due to how the telescopes are made. you should look into it, it's actually really interesting. by looking at the diffraction spikes, you can tell a bit about how the telescope is built.
Not really a term used in astronomy. Presumably OP meant "massive star", which Wolf-Rayet stars like this one always are. They are however also usually uncommonly dense objects, often packing more than 10 solar masses into a volume smaller than the Sun's.
Go try to lift the Sun and you will find out, just donβt forget your sunscreen. But I guess they should have said massive. All stars are massive but some are more massive than others.

The image of the star per se has exactly zero resolution. What we're looking at is the surrounding nebula, caused by the violent, paroxysmal eruptions this massive star is having in the final stages of its life.
Knowledge and understanding is valuable in and of itself. Not everything that people do has to serve economic ends. See also the music, art, literature, sports, philosophy, spirituality, relationships, etc. What are those things for? They help us generate a purpose for existing.
This is Wolf-Rayet 124 (WR 124) a massive star approximately 15,000 light-years from Earth in the constellation Sagitarius. The star burns fast and hard and produces heavier elements that will one day be ejected into space when the star goes supernova. Tail waggingly stunning.
The nebula is material being ejected by the star. The star is called a "Runaway star." It has been expelled from it's star nursery by other larger stars and is the fastest known runaway in the Milky Way. The Nebula is expanding at roughly 93,000 miles an hour.
Can't imagine what life is doing in there. Probably looking at us with slighted eyes. If they have them. Shit....what we see happened millions of years ago. Now they have a retirement plan hopefully...
Look closely. There are actually 8 spikes from each star. There are 6 spikes from the primary mirrors but there are also 6 spikes from the struts that hold the secondary mirror. Four of those are overlapping with four of the original 6 so we see a total of 8.

Just extremely heavy...

If you collect everything back, it will blow again.

Whatβs it for?
That image, in addition to being beautiful, what else would it be useful?
