### Quick! Assign the letters JHMLCNVTURISEYAPO to the integers -8 to 8 and tell me what you get…

… a piece of brilliant recreational math from Lee Sallows.

Specifically:

S + U + N = 3 + 0 – 3 = 0
M + E + R + C + U + R + Y = -6 + 4 + 1 – 4 + 0 + 1 + 5 = 1
V + E + N + U + S = -2 + 4 – 3 + 0 + 3 = 2
E + A + R + T + H = 4 + 6 + 1 – 1 – 7 = 3
M + A + R + S = – 6 + 6 + 1 + 3 = 4
J + U + P + I + T + E + R = -8 + 0 + 7 + 2 – 1 + 4 + 1 = 5
S + A + T + U + R + N = 3 + 6 – 1 + 0 + 1 – 3 = 6
U + R + A + N + U + S = 0 + 1 + 6 – 3 + 0 + 3 = 7
N + E + P + T + U + N + E = -3 + 4 + 7 – 1 + 0 – 3 + 4 = 8
P + L + U + T + O = 7 – 5 + 0 – 1 + 8 = 9
E + R + I + S* = 4 + 1 + 2 + 3 = 10

### I think we can all agree that nebulae are just pretty

That is: “A nebula (from Latin: “cloud”; pl. nebulae or nebulæ, with ligature or nebulas) is an interstellar cloud of dust, hydrogen, helium and other ionized gases.” (from Wikipedia)

### The sun is gorgeous? Yes, it is: especially when viewed under different wavelengths. #wow via @kejames

“Yellow-green light of 5500 Angstroms, for example, generally emanates from material of about 10,000 degrees F (5700 degrees C), which represents the surface of the sun. Extreme ultraviolet light of 94 Angstroms, on the other hand, comes from atoms that are about 11 million degrees F (6,300,000 degrees C) and is a good wavelength for looking at solar flares, which can reach such high temperatures. By examining pictures of the sun in a variety of wavelengths – as is done through such telescopes as NASA’s Solar Dynamics Observatory (SDO), NASA’s Solar Terrestrial Relations Observatory (STEREO) and the ESA/NASA Solar and Heliospheric Observatory (SOHO) — scientists can track how particles and heat move through the sun’s atmosphere.”

### One of the earliest Mars images was a digitally reconstructed paint-by-numbers.

“A “real-time data translator” machine converted a Mariner 4 digital image data into numbers printed on strips of paper. Too anxious to wait for the official processed image, employees from the Telecommunications Section at NASA’s Jet Propulsion Laboratory, attached these strips side by side to a display panel and hand colored the numbers like a paint-by-numbers picture. The completed image was framed and presented to JPL director, William H. Pickering. Mariner 4 was launched on November 28, 1964 and journeyed for 228 days to the Red Planet, providing the first close-range images of Mars.”
