The detail of Earth 🌍 captured in Bill Anders’ first color photo taken from lunar orbit on #christmaseve in 1968 #OTD really is amazing. This is a crop of AS08-14-2383, in its original orientation, from a scanned 70mm @nasa film original 16-bit TIFF file by a project team at Arizona State University

This is the silhouette of 1,122-km-wide Dione in front of Saturn—a view captured with Cassini 15 years ago on December 20, 2010. Synthesized color from a single clear-filter greyscale image.

45 years ago today we got our first closeup of the Solar System’s very own “Death Star!” Captured by Voyager 1 on November 12, 1980 as it passed Saturn, this image (PIA01968) shows the moon Mimas with its 139 km wide, 5 km deep Herschel crater making it resemble the Empire’s infamous space station.

On November 10, 1967 #OTD NASA captured its first color picture of the entire daylit side of Earth from space using the Multicolor Spin-Scan Cloudcover Camera on the ATS-3 weather satellite from an altitude of about 22,000 miles. (More on the MSSCC here: journals.ametsoc.org/view/journal...)

This is what the band of the Milky Way would look like at night if your eyes could see radio waves. A hidden beauty. It's a new image created by the Murchison Widefield Array, which scanned the sky in 20 radio "colors" over frequencies from 72 to 231 megahertz. 🧪🔭 www.icrar.org/gleam-x-gala...

While shooting the moonrise last night (since the eastern horizon was relatively free of clouds) I did get to capture another nice green flash along the Moon's upper limb. (Really more of a wavering flicker than a flash, but it was visible through the viewfinder.) 📸🌖

This was a cool place to visit!

Jupiter's colorful, lava-coated moon Io imaged by NASA's Galileo spacecraft on October 16, 2001

Dione in front of Saturn, captured by Cassini 20 years ago today on October 11, 2005 🌖🪐

A little bit of the "green flash" captured during Sunday night's sunset

The Moon and Earth together captured with a camera aboard the ESA European Service Module during NASA's Artemis I mission on November 28, 2022. The spacecraft was about 42,000 miles beyond the Moon when this picture was taken.🌖🌍

The Sun eclipsed by the Moon—a photo captured in the midst of the brief period of totality during the August 21, 2017 solar eclipse.

Cassini's final full view of Saturn 🪐 a mosaic comprising 11 color-composites captured by the spacecraft in visible light filters on September 13, 2017. The following day it dove into Saturn's atmosphere, ending its mission after 13 years in orbit.

Io in front of Jupiter. This is a color-composite made from images captured by NASA's Galileo spacecraft in red, green, and violet wavelengths on September 6, 1996. Io is the most volcanically-active world in our solar system.

Tonight’s waxing gibbous Moon 🌔

and this is just level 1 of The Total Perspective Vortex

If we equate Earth with the scale size of a basketball, the Moon would be about the size of a tennis ball, 24 feet (7.3 m) away. 🌎🌖 The Sun would be a sphere 86 feet (26 m) wide—about the height of an 8-story building—1.8 miles (2.9 km) away. 🌞

This is a closeup of the 1909 Lincoln penny that's been on Mars as part of Curiosity's MAHLI calibration target for almost 13 years

Fun fact: all of the other planets in the Solar System—and Pluto too—lined up edge-to-edge (not including any rings) could fit between Earth and the Moon

The crescent Moon with earthshine next to the Pleiades tonight 🌒✨

Saturn's moon Mimas with the 139 km wide Herschel crater positioned dead-center along the terminator, imaged by NASA's Cassini spacecraft on March 20, 2006

NASA's Lunar Reconnaissance Orbiter captured the Firefly Aerospace Blue Ghost lander on the surface from a distance of about 190 km on March 2, 2025 about 9 hours after touchdown. (Source: lroc.asu.edu/images/1406; image upscaled, my edit.)

This is wonderful—an orbital Earth set and rise from Firefly Aerospace's Blue Ghost lander as it passed behind the Moon on February 18 🌕🌍 (watch in 2160 HD if you can) youtu.be/kB66ECu4kL8?...

On November 11, 1935, the National Geographic/Army Air Corps-operated Explorer II mission launched a balloon with a pressurized gondola to a record altitude of 72,395 ft. The two-man crew captured the first photos showing the division of the troposphere and stratosphere, and Earth's curved horizon.

41 years ago today: Bruce McCandless piloted his Manned Maneuvering Unit (MMU) nearly 100 meters away from Space Shuttle Challenger during STS-41B. Iconic shuttle era moment!

Tonight’s Moon and Venus

A rare “green flash” captured above the rising full Moon on October 17, 2024. This optical effect is caused by light refracted through the atmosphere near the horizon, briefly separating the green wavelengths from the red and orange.

How the Lunar Roving Vehicles were deployed from the quadrant 1 bay of the Apollo LMs. This is television camera video from Apollo 15 in July 1971 showing Dave Scott; Jim Irwin off frame (3 separate clips spliced together playing at 5x speed with overlaid audio at normal speed.)

Here’s a view of Uranus’ moon Miranda, a 470 km-wide spheroid of ice and rock with some of the most contorted terrain in the Solar System. This view comprises 8 images captured by Voyager 2 on January 24, 1986 from 32,000 km away.

On the left is Earth photographed from the Apollo 11 landing site during EVA on 21 July 1969 at approximately 04:19 UTC (crop of AS11-40-5923). On the right is the @celestiaproject.bsky.social view (north: right) from the same lunar coordinates @ same time/date. Lines up very well! (As it should.) 🌏

I’m an anxious neurodivergent gal but will continue to do my best being a positive voice. I get overwhelmed easily now & find peace in my art business, hiding away and painting. But know that here we fight for science, for conservation, & for human rights 🏳️‍🌈🏳️‍⚧️ Today I finished Mars on clay

A view of Saturn's moon Atlas orbiting beyond the outer edge of the A ring in the 3,000-km-wide space between it and the F ring (the Roche Division) with Saturn's shadow falling onto the rings at the left. Captured with Cassini on January 19, 2007

Yes, there will be a lineup of planets in the sky this month but they're not actually "aligned" in their orbits...they just happen to be on the same side of the Sun right now to all be visible from Earth between dusk and dawn.

This is Jupiter’s moon Io in eclipse, imaged with Cassini's narrow-angle camera from a distance of 11.4 million km on January 5, 2001. The ring is the glow of Io's thin atmosphere interacting with the plasma environment around Jupiter.

Could Apollo astronauts see ✨stars✨ during their lunar missions? Yes, but only when the lighting was right—like on the Moon's night side.🌑 They mentioned stars many times, in fact.

The Moon and Venus tonight 🌒🌟
