spacefromspace.com/declassified... is now home to over 700 georeferenced spy satellite images of locations all over the world taken between 1960 and 1984!

I've also published a new, very experimental, map view search method for all images available on the website: spacefromspace.com/declassified...

Supermoon rising over Sacré-Cœur France

Last month, as the first full Moon of the year crossed the night sky, the weather was cloudless in Paris and I had the chance to plan a picture of its path during its rise above the city. What is a supermoon? A supermoon is a full Moon that occurs when the Moon is at or near its closest point to Earth in its orbit, called perigee. The day before I also shot the full moon path during sunset above the Eiffel Tower and Sacré-Coeur. This time the Moon rose just at the beginning of the night sky. The weather was good but quite cold, and a mix of frost and snow covered the ground. This image was taken with a 150–600mm lens at 600mm. The Sacré-Cœur Basilica was 11 km away from my position, which explains why the Moon appears so large in the frame compared to the building. The final image is a slight crop of the original frame to refine the composition and emphasize the Moon’s diagonal path.

In this image a shot during landing of Nasa Perseverance from the perspective of the rover. The heat shield was already released and it's visible at the centre of the image. In the background the rim of the Jezero Crater and its delta. Colours assigned are from the dark of the more external atmosphere layers to the rusty red of the red planet surface.

Five years and counting!

I can't believe it has already been 4 years since the Perseverance rover landed on Mars! #planetsci

The rover was equipped with six engineering camera that captured more than 26.000 images during the landing!

This thread contains some of my favorites:
A red-white striped parachute seen from below against a reddish-grayish sky. The perseverance heatshield falling away towards the surface of Mars. The inside is black and has serveral orange cables running across. around the perimeter are eight spiral springs that helped to push the heatshield away. The Perseverance rover as seen from the skycrane above, dangling from three ropes and a cable umbilical. The Red Mars dust from the surface is getting blown away where the plume from the skycrane hits the the martian surface. The rover deck is still remarkably clean as compared to later in the mission. The skycrane from below, partially obscured by Mars dust and small rocks it flies away. Each of the four corners has a pair of thrusters and the umbilical cable that has just been cut is curled up below the skycrane.

View of Mars from orbit, showing a curved horizon against the blackness of space. The dusty tan surface is marked by scattered impact craters and rugged ridges. Along the horizon, a thin pale bluish atmospheric layer creates a misty glow, and a single distinct white cloud is visible near the upper layers of the atmosphere.

The Vandenberg launch of February 14th, 2026 was optimally timed for illumination of the initial as well as the lingering plume. Tonight this plume underwent intriguing looping and stretching as Earths shadow passed across it with reds, golds and blues dominating the last lighting here and there.
The colors of the last sunlight paint the loops and bands of the plume from the Vandenberg launch of the evening of February 14, 2026. Golds and blues dominate the color of the lighting in different parts of the plume depending on their altitude and proximity to the Earth shadow edge. This edge is lined with a spectral gradations of filtered sunlight going from white to yellow to orange and deep red. In places a bright blue glow dominates, perhaps from the colors most efficiently 'forward scattered' from the full spectrum sunlight upon the highest portions. This photograph is from a tripod mounted Canon SLR with an exposure of 3.2 seconds at ISO 1000 at F5.6. This is thus brighter and more colorful than the eye saw it but the detail and color are real. Think of it as a form of wide angle Astrophotraphy.

The deposits around the volcano Pele on Io looked like a heart as Voyager 1 approached in March of 1979. For today, I rotated it around to emphasize that. By the time Galileo saw it in 1996, the indentation at the top of this image was mostly gone. Happy Valentine's Day!

Hyperbolic Oort Cloud Comet: This conjunction was a million years in the making. On Feb. 9th, Daniele Gasparri of Atacama, Chile, photographed Comet Wierzchoś (C/2024 E1) gliding past the "string of pearls galaxy" NGC 55.
spaceweathergallery2.com/indiv_upload...
spaceweather.com/archive.php?...
There is a little-known comet, best seen from the Southern Hemisphere, putting on a beautiful show. On the night of February 9, it passed close to the bright galaxy NGC 55. Comet Wierzchos is not very bright and is not visible to the naked eye, but it displays a long, striking tail and it is a very beautiful telescopic object. This image captures the closest approach to NGC 55, taken from the Atacama Desert with my 20 cm Newtonian telescope. I had to deal with a huge amount of satellite tracks (on average 3-4 for each 120 seconds exposure), which almost ruined my attempt to image the comet and the galaxy. The photo is a two panel mosaic made to include the full extent of NGC 55. Even so, the field of view is not wide enough to show the full length of comet tail. Each panel is the average of 10X120 seconds exposures, aligned both on stars and the comet.

This is a real timelapse video of the Moon transiting in front of the Earth.

It was captured by the Artemis 1 Orion spacecraft in November 2022 while flying at it's furthest point from the Earth.
The video covers about 3.75 hours of real time. 🔭🧪

Crescent Saturn and Titan - From Val Klavans (valklavans.bsky.social) - https://flic.kr/p/fv6rVE
On August 11, 2013 Cassini's camera system, the Imaging Science Subsystem, captured a set of images of Saturn and Titan. This is a natural color composite of three images ISS snapped in red, green, and blue filters. Saturn and Titan appear as crescents here because Cassini was almost completely behind the worlds as they faced the Sun. These images were taken on August 11, 2013 and received on Earth August 14, 2013. The camera was pointing toward SATURN at approximately 1,065,949 miles (1,715,478 kilometers) away, and the images were taken using the red, green, and blue filters.

Chilled New York City

NASA Earth Observatory image by Michala Garrison, using Landsat data from the U.S. Geological Survey. 🧪🔭

science.nasa.gov/earth/earth-...
A satellite image of the New York metropolitan area showing the effects of a prolonged cold spell in late January 2026. During a stretch of frigid weather, ice choked the Hudson River along Manhattan’s western shore. The OLI (Operational Land Imager) on Landsat 8 captured this image of the wintry landscape around midday on January 28. The image is false-color (bands 5-4-3) to distinguish ice (light blue) from open water and snow. Vegetation appears red. Ice is abundant in the Hudson River and visible in smaller amounts in the East River, the Jacqueline Kennedy Onassis Reservoir in Central Park, and waterways in New Jersey.

Sixty years ago today, on February 3, 1966, Luna-9 was the first spacecraft to survive landing on the surface of another world. It is wild to think that the Space Age is so young that there are still millions alive now who were adults when this happened.
