Sh2-297
[edit]- ... that a protostar in the Sh2-297 nebula is driving an outflow of gas more massive than the Sun? Source: "The masses inside the two outflow lobes are again calculated by integration of H2 column densities, resulting in M_blue=1.8 M_sun and M_red=3.6 M_sun, the total outflow mass being M_out=5.4 M_sun." ([1])
- ALT1:... that a massive B-type star has created a bubble of ionized hydrogen in the Sh2-297 nebula? Source: "Optical spectroscopic observations are used to constrain the spectral type of ionizing star HD 53623 as B0V. The classical nature of this H ii region is affirmed by the low values of electron density and emission measure, which are calculated to be 756 cm−3 and 9.15 × 105 cm−6 pc ..." ([2])

New enough, long enough, with both article and hook properly sourced. The writing is I think overly WP:TECHNICAL and has some grammatical issues (the unnecessary comma at the start of the second paragraph, "that it undetectable" later) which could use repair, and the "See also" violates the suggestion in WP:SEEALSO of avoiding links that are already in the main article text, but those are not blocking issues for DYK. Pretty image, even at 100px, with proper image licensing under a CC-BY-SA license verified at the image source. Earwig found absolutely no copying. QPQ done. Good to go. I much prefer the original hook to ALT1; the original hook is exciting (it's passing a whole sun's worth of gas!) and explained in simple words, while ALT1 is jargony and I don't see why the average reader should care. —David Eppstein (talk) 07:06, 18 March 2017 (UTC)
