Explanation: Where do comet tails come from? There are no obvious places on the nuclei of comets from which the jets that create comet tails emanate. In 2016, though, ESA's Rosetta spacecraft not only imaged a jet emerging from Comet 67P/Churyumov-Gerasimenko, but flew right through it. Featured is a telling picture showing a bright plume emerging from a small circular dip bounded on one side by a 10-meter high wall. Analyses of Rosetta data show that the jet was composed of both dust and water-ice. The rugged but otherwise unremarkable terrain indicates that something likely happened far under the porous surface to create the plume. This image was taken about two months before Rosetta's mission ended with a controlled impact onto Comet 67P's surface.

Again I ask...
How does this make muslims feel good about themselves?
“and perhaps foremost, he wanted me to find a way to reach out to the Muslim world and engage much more with dominantly Muslim nations to help them feel good about their historic contribution to science … and math and engineering,” - Charles Bolden, Obama’s NASA director...

We call Ptolemy’s great work on astronomy, written in Greek, by its Arabic name. We use Arabic names for a number of the brightest stars (Vega, Altair, Rigel, Deneb, etc.). Isn’t that enough tribute to medieval Muslim astronomers?
To: Verginius Rufus
Also, the highest rank in our navy and coast guard is an Arabic term.

That’s an amazing picture. It brings to mind the movies Deep Impact and Armageddon. I don’t get what it has to do with Arab star names.

Comet tail images make a lot more sense when their electrical nature is considered.

Not to mention Al Cohol.
Have to be careful mentioning Al Gebra. Might stir up Islamophobia among kids who hate algebra.
Our numerals are called Arabic numerals but they weren't really invented by the Arabs--the Arabs got them from India.
