Like dust bunnies that lurk in corners and under beds, surprisingly complex loops and blobs of cosmic dust lie hidden in the giant elliptical galaxy NGC 1316. This image made from data obtained with the NASA/ESA Hubble Space Telescope reveals the dust lanes and star clusters of this giant galaxy that give evidence that it was formed from a past merger of two gas-rich galaxies.

Happy Caturday to you! This last week I was working out some of the math behind my fictional monster planet Bruticus, and sadly had not the time to post it in complete form online, at least what’s finished. I’ve got the mass, diameter, and gravity of the planet figured out, but with that must come the data on its five large moons, and the number-crunching for the takeoff mass and delta-V of the biological spacecraft used to travel to and between them. That will be by the end of the next week, either for this coming Thursday or next Caturday in complete form. This has taken longer than I’ve expected, but it will be good to get it all down on paper and online. Thanks to Ray and Anneliese for the help so far, and may you always get at least a few clear nights out of a month!
