The tadpoles of NGC 3572. Image: Josep M. Drudis.
Carlos Taylor's portrait of NGC 3572 shows us a large almost circular nebular mass with what looks like a cavity in the center, and something, maybe an animal, appears to be coming out of that cavity. Two big jet-like extensions of the nebula are seen at upper right. The picture is interesting, and it's a fine portrait, but the tadpoles of NGC 3572 are not allowed to shine.
(Okay... so... maybe that "bear"

coming out of the "cave" is actually the base of one of the tadpoles?)
I prefer Josep M. Drudis' portrait of the tadpoles. His picture was an APOD on November 8, 2019. Go
here to see it, and to see a larger version of his picture, too.
P.S. Oh, and if you are all that interested, you may note a free-floating red blob at upper left in Josep Drudis' image. There is a
paper from 2003, published in Astronomical Society of the Pacific, on this nebula. It's gritty reading, if you ask me, but the conclusion of the authors is that the object is probably not a planetary nebula but a photoevaporating globule - a blob of gas that is a remnant from the nebula that gave rise to the cluster - which is being ionized not from within but by the hot O8-type star of the cluster of NGC 3572. They even seem to suggest that there might be a T Tauri star, a baby star that is not yet fully formed, inside the red blob. (But maybe I didn't get them right there, because they were unable to detect the very faint central star that Josep Drudis has revealed to us.)
