Cone Nebula (NGC 2264) by nasa
![Resembling a nightmarish beast rearing its head from a crimson sea, this monstrous object is actually an innocuous pillar of gas and dust. Called the Cone Nebula (NGC 2264) - so named because, in ground-based images, it has a conical shape - this giant pillar resides in a turbulent star-forming region.
This picture, taken by the newly installed Advanced Camera for Surveys (ACS) aboard NASA's Hubble Space Telescope, shows the upper 2.5 light-years of the nebula, a height that equals 23 million roundtrips to the Moon. The entire nebula is 7 light-years long. The Cone Nebula resides 2,500 light-years away in the constellation Monoceros.
Radiation from hot, young stars [located beyond the top of the image] has slowly eroded the nebula over millions of years. Ultraviolet light heats the edges of the dark cloud, releasing gas into the relatively empty region of surrounding space. There, additional ultraviolet radiation causes the hydrogen gas to glow, which produces the red halo of light seen around the pillar. A similar process occurs on a much smaller scale to gas surrounding a single star, forming the bow-shaped arc seen near the upper left side of the Cone. This arc, seen previously with the Hubble telescope, is 65 times larger than the diameter of our solar system. The blue-white light from surrounding stars is reflected by dust. Background stars can be seen peeking through the evaporating tendrils of gas, while the turbulent base is pockmarked with stars reddened by dust.
Over time, only the densest regions of the Cone will be left. Inside these regions, stars and planets may form.
The Cone Nebula is a cousin of the M16 pillars, which the Hubble telescope imaged in 1995. Monstrous pillars of cold gas, like the Cone and M16, are common in large regions of star birth. Astronomers believe that these pillars are incubators for developing stars.

Trump's nominee to run NASA has very little to do with an isolated nearby dwarf galaxy and yet here I am writing about both!

Who is Jared Isaacman? And a new nearby yet isolated dwarf galaxy
Trump’s pick to run NASA is a public figure but its unclear how well he’d do as the space agency administrator

Next time you have an idea that seems too crazy, just remember that John Woo once walked into an office and said "I wanna make a movie where Nick Cage plays John Travolta playing Nick Cage, and John Travolta plays Nick Cage playing John Travolta," and someone wrote him a check for 80 million dollars

I honestly believe all LLM results should come with a disclaimer reminding people that the thing doesn’t (and absolutely cannot) know any facts or do any reasoning; it is simply designed to *sound* like it knows facts and frequently sweeps some up accidentally in the process.
I really think many if not most of the LLM fail cases are people trying to use it as a search engine. It is the opposite of a search engine.
