Saturn has a mysterious hexagon at its north pole that has refused to give up its secrets, probably because neither Voyager 1 nor Cassini was able to plunge that deep and survive. Harvard scientists Rakesh Yadav and Jeremy Bloxham might have finally started to figure out what causes this peculiar feature. They believe that vortexes occur at the planet’s north pole because of atmospheric flows deep within the gas giant, and that these vortexes pinch an intense horizontal jet near the equator—which is what warps the storm into a hexagon. It still looks unnatural though.....!!!
Stars form when bodies of dust and gas create enough mass to create a gravitational effect that's able to then pull in more gas, the process continues and the mass increases until the pressure at the centre is sufficient for fusion to begin.
There's many examples of protostars, in fact back in 2012, NASA’s Spitzer Space Telescope focused in on L1527 IRS, believed at the time to be the youngest forming star ever found.
Recently, the JWST re-visited this protostar, and the title image was the result.
The forming star cannot be visually spotted, but is thought to be around 20-40% the mass of our own Sun already.
If you look closely, you can see there's a dark patch in the centre, this is actually the accretion disk around the newly formed star, what is left over after the formation, may go on to form the planets, in fact, they may be actually starting to be created already, as recent evidence does point to planets being born around the same time as the star does in many cases.
The protostar is only 450 light years from Earth in the Constellation of Taurus, and is thought to be around 100,000 years old, a blink of an eye in the life of a star, particularly of this mass.

the new composite james webb image is so beautiful ive been staring at it for 10 minutes straight
featuring jupiters rings, europa (along with a bunch of other moons), the northern and southern auroras, and the great red spot
The Venus girdle (Cestum veneris) is a comb jelly in the family Cestidae. The colorless species are transparent when suspended in water, except for their iridescent rows of comb plates. In other words, they majestic as fuck. Love to sea it 🌊
