Cosmic Latte: The Average Color of the Universe : What color is the universe? More precisely, if the entire sky were smeared out, what color would the final mix be? This whimsical question came up when trying to determine what stars are commonplace in nearby galaxies. The answer, depicted above, is a conditionally perceived shade of beige. In computer parlance: #FFF8E7. To determine this, astronomers computationally averaged the light emitted by one of the larger samples of galaxies analyzed: the 200,000 galaxies of the 2dF survey. The resulting cosmic spectrum has some emission in all parts of the electromagnetic spectrum, but a single perceived composite color. This color has become much less blue over the past 10 billion years, indicating that redder stars are becoming more prevalent. In a contest to better name the color, notable entries included skyvory, univeige, and the winner: cosmic latte. via NASA

NASA: we're building a probe that can withstand the conditions inside Jupiter!
Me: cool
NASA: we're launching the probe now! Can't wait to explore the inside the biggest planet in the solar system!
Me: me too!
NASA: so we found a giant eye and mouth at the center of Jupiter and lost contact with the probe :)
Me:
Me: say sike right now

HiPOD 18 Oct 2021: Fresh Craters in the Northern Mid-Latitudes
These two impact craters near Deuteronilus Mensae dominate the center of this observation, also visible in Context Camera images. Both are fairly small and geologically young (hence “fresh”) but the flower-like ejecta of one of them is what stands out here. A collection of boulders surround both.
Black and white is less than 5 km across; enhanced color is less than 1 km.
ID: ESP_064497_2250 date: 30 April 2020 altitude: 302 km

Earthshine Moon over Sicily via NASA https://ift.tt/30rFa5u
Why can we see the entire face of this Moon? When the Moon is in a crescent phase, only part of it appears directly illuminated by the Sun. The answer is earthshine, also known as earthlight and the da Vinci glow. The reason is that the rest of the Earth-facing Moon is slightly illuminated by sunlight first reflected from the Earth. Since the Earth appears near full phase from the Moon -- when the Moon appears as a slight crescent from the Earth -- earthshine is then near its brightest. Featured here in combined, consecutively-taken, HDR images taken earlier this month, a rising earthshine Moon was captured passing slowly near the planet Venus, the brightest spot near the image center. Just above Venus is the star Dschubba (catalogued as Delta Scorpii), while the red star on the far left is Antares. The celestial show is visible through scenic cloud decks. In the foreground are the lights from Palazzolo Acreide, a city with ancient historical roots in Sicily, Italy.

Fox Fur, Unicorn, and Christmas Tree : Clouds of glowing hydrogen gas fill this colorful skyscape in the faint but fanciful constellation Monoceros, the Unicorn. A star forming region cataloged as NGC 2264, the complex jumble of cosmic gas and dust is about 2,700 light-years distant and mixes reddish emission nebulae excited by energetic light from newborn stars with dark interstellar dust clouds. Where the otherwise obscuring dust clouds lie close to the hot, young stars they also reflect starlight, forming blue reflection nebulae. The telescopic image spans about 1.5 degrees or 3 full moons, covering nearly 80 light-years at the distance of NGC 2264. Its cast of cosmic characters includes the the Fox Fur Nebula, whose dusty, convoluted pelt lies left of center, bright variable star S Monocerotis immersed in the blue-tinted haze near center, and the Cone Nebula pointing in from the right side of the frame. Of course, the stars of NGC 2264 are also known as the Christmas Tree star cluster. The triangular tree shape is seen on its side here. Traced by brighter stars it has its apex at the Cone Nebula. The tree's broader base is centered near S Monocerotis. via NASA

Relaxing after the mission. Astronaut John Glenn kicks back following his historic Project Mercury flight to become the 1st American to orbit the globe. His 5 hour flight in Feb ‘62 orbited Earth 🌍 3x before splashdown. Russian cosmonaut Yuri Gagarin was both the 1st human in space & to orbit the globe in his Vostok craft in April ‘61. Glenn continued his NASA career to accomplish the formidable feat of being the oldest in space, at that time, at 77 years of age during a Space Shuttle Discovery flight in 1995; a true space pioneer & legend.
