Starship Asterisk*

Good post, thanks.
One copyediting note: "although the future brightness of comets is notoriously hard to predict", not "are".

Thank you for posting this nice image, Otto. Copyediting note: The asteroid diameter should read "10 km", not "10-km". Hyphenation would be used for the adjectival form, e.g. "One day, the Vogons sent a 10-km asteroid to the Earth, and thereby saved the cetaceans from the hu...

Cool pic, thanks. Copyeditor's note: "...its geometry of shells and arcs is surely intriguing." The sentence subject is geometry, which is singular.

Thanks for another good APOD.
Unsolicited copyeditor's note: "170 meters" takes no hyphen. Only measurements expressed as an adjective should be hyphenated: "DART collided with the 170-meter asteroid yesterday."

Also, side note to Otto: "fit 'iconically' inside the rock arch"??

Otto, thanks for the heads-up and the excellent graphic! But here the Pleiades are being invaded by a much smaller interloper as well: the dreaded 21-st-century inappropriate hyphen! :shock: "naked eye" does not want a hyphen here, only when used as a compound adjective: "naked-eye ob...

Nice pic, thanks!

Great image, thanks! Typo note: Carngegie > Carnegie.

Great pic. Has anyone been able to follow the link to the full-res image? I'm getting a "not found" when I try.
