Sometimes It Amazes Me That The Juno Spacecraft Was Originally Designed Without Any Cameras Onboard.

Sometimes it amazes me that the Juno spacecraft was originally designed without any cameras onboard. The JunoCam instrument has produced stunning imagery of Jupiter thus far and shows no signs of stopping soon. The latest wonder is this false-color, high-contrast animation showing the motion of Jupiter’s clouds swirling and flowing past one another. 

Now, this is not Jupiter as you would see it by eye. This animation is derived from two images taken 8 minutes and 41 seconds apart. In that time, Juno  covered a lot of distance, so the two images had to be mathematically re-projected so that they appeared to be taken from the same location. Then, by comparing relative positions of recognizable features in the two photos and applying some understanding of fluid mechanics, observers could calculate the probable flow between those two states. Although this is a coarse example, it’s the same kind of technique often used in fluid dynamical experiments when measuring how flows change between two images. (Image credit:  NASA/JPL/SwRI/MSSS/G.

Scientists Just Spotted An Adorable Star That Barely Even Qualifies As One

Scientists just spotted an adorable star that barely even qualifies as one

Sometimes, scientists’ categories for things can be a little demeaning. For example: the “failed star” designation for objects that are larger than planets but smaller than stars.

About 600 light-years away, EBLM J0555-57Ab just barely missed the failed star category. But as will be published in an upcoming issue of the journal Astronomy & Astrophysics, it’s just a hair over the boundary, making it one of the smallest stars we know of.

“Failed star” is actually a factual statement — it just means something isn’t large enough to manage to bang hydrogen atoms together to form helium, the basic process at the heart of a burning star.

EBLM J0555-57Ab looks a bit like it shouldn’t have made the cut: It’s only a tiny bit larger than Saturn, or about one-twelfth the size of our sun. Read more (7/12/17)

This Was The Crossword Puzzle In The New York Times Yesterday. 

This was the crossword puzzle in the New York Times yesterday. 

Tausig’s crossword is a so-called Schrödinger puzzle, named for the physicist’s hypothetical cat that is at once both alive and dead. In a Schrödinger puzzle, select squares have more than one correct letter answer: They exist in two states at once. “Black Halloween animal,” for example, could be both BAT or CAT, yielding two different but perfectly correct puzzles. Only 10 such puzzles have now been published in Times history.

It’s the theme of Tausig’s puzzle, though, that makes it special. Four entries in Thursday’s crossword can include either an “F” or an “M.” Both are correct; neither is wrong. For example, “Part of a house” can be either ROOF or ROOM. The long “revealer” answer, tying those select entries together and spanning 11 squares smack-dab in the middle of the puzzle, is GENDER FLUID.

This puzzle, with “M”s and “F”s that aren’t fixed, is a masterful blend of subject and structure. “It potentially really evokes what gender fluidity is, which is not moving back and forth between two poles, but actually not being committed to either pole, and potentially existing in many states at different times,” Tausig said.

To some people you’re an NPC

To other people, you’re the special, unlockable character that they worked and worked to finally get- and when they do they’re so happy because they got the game just so they could find you.
