After the sampling operations of conglomerates at Fall River Pass were completed, the Perseverance Rover started moving West through very Rocky terrain towards a new Science objective, called the Margin Carbonate Unit. This area is 400m west of the rover an not yet visible from the current location. Scientists hope to learn more about the past environment on Mars from the rocks there and whether it facilitated life. This panorama was assembled from Navcam images taken on the afternoon on Sol 904. I also added sky images from sol 889. These images were taken at a different time of day, but at the same sun elevation, so they could be combined. Credit: NASA/JPL-Caltech/ASU/Simeon Schmauß

The Remote Micro-Imager (RMI), part of ChemCam instrument aboard Curiosity rover, is a telescope which provides high resolution pictures for close and remote targets. On sol 4667 (September 22th, 2025), RMI has imaged the 3.5 kilometer distant cliffs in the Yardang Unit of Gale crater, Mars. The steep cliff on the center of the image is approximately 39 meters high. This is one of the most impressive pictures taken by RMI during MSL mission.

La Nebulosa del Velo, NGC 6992, es una nebulosa clasificada como resto de supernova. En realidad, la imagen (de tamaño 20 x 10 minutos de arco) sólo muestra una pequeña parte de toda la nebulosa. Los colores representan el filtro B (azul), la famosa emisión de [O III] (verde) y la emisión de Hidrógeno-alfa, Ha (rojo). Esta imagen, realizada por Jorge García Rojas y un servidor de ustedes, es una combinación de 2 campos usando la antigua CCD del telescopio IAC-80. En realidad, es una prueba que hicimos en el mismo telescopio justo antes del amanecer, en verano de 2004. Ahora nuestras imágenes están mucho más curradas :D

On the left is a true color image of Titan. The moon's north polar hood is visible in this view. The image on the right is a representation of what it would look like if you could see past Titan's atmosphere and down to its surface. The darker areas are vast hydrocarbon sand dunes and seas. Up north, some of Titan's lakes and seas are visible. Down below, a portion of Titan's hydrocarbon sand dunes can be seen. Both views were taken by the Cassini spacecraft on May 4, 2014, as it was looking for clouds across Titan's northern hemisphere. More info: www.ciclops.org/view/7871/Rev204.

False color infrared image of the Columbia Hills in Gusev Crater. This region was explored by the Spirit rover between 2004 to 2010. The mission landing site was chosen with the expectation that the flat terrain of Gusev Crater were sediments deposited in a lake fed by Ma'adim Vallis, a large canyon system that empties into Gusev. However, it became clear soon after landing that the crater is filled by a vast lava plain. Although lake sediments are probably present in Gusev, they are buried by these lava flows. A greater of diversity of rocks were seen in the Columbia Hills, many of which appeared to be sedimentary and volcaniclastic rocks. This has led some researchers to suggest that the Columbia Hills represent an exposure of lakebed sediments that were folded towards the surface along a thrust fault (one of several in Gusev). Images of rocks in the visible range of the spectrum (380-780 nm) usually show very small changes in color. However, rocks are much more colorful in the 1000 nm to 2600 nm range due to the presence of strong absorption features related to common transition metals (such as iron) in mineral crystals. These differences help highlight the difference between the relatively bland rocks of the Gusev lava plains and the more compositionally diverse rocks exposed in the Columbia Hills. This false color was created using the CRISM imaging spectrometer. Each pixel of a CRISM image contains a 500 point spectrum, from which a color can be reconstructed. This...

This image shows the famous Trifid nebula in Sagittarius, also known as Messier 20 or NGC 6514. This particular nebula is a classic favourite among both visual and photographic observers due to its bright and colourful appearance. The complex cloud displays an unusual combination of both red emission and blue reflection areas as well as numerous intricate dark patterns. The nebula is located 9000 light years away in the direction of the Milky Way centre. The entire area is sprinkled with thousands of stars and fainter dusty and nebulous areas throughout. Another dark cloud shows up silhouetted against the starry background to the left of the Trifid. Near the top of the Trifid itself a curious example of gas evaporation can be seen. A dense stalk, 8 light years from the central cluster, is emerging from the edge of the bubble surrounding the central cluster, and in the other direction a powerful stellar jet from a young star, HH 399 embedded in the gas, is shooting out in a direction towards the bottom right. The bright young stars in the central cluster emit strong radiation which eats away the surrounding gas and dust. The stalk only appears because a denser region lies at its very tip and protects a thin strip of the cloud from this interstellar erosion. The Hubble Space Telescope has imaged this fascinating area in high resolution. Also, the proper motion of the irradiated plasma in this jet has been measured and an interesting paper has been published detailing these ...

Dawn mosaic of the asteroid 4 Vesta, taken from an altitude of ~2800 km on October 19, 2012. This image is a mosaic of three black and white images taken of the asteroid as the spacecraft prepared to descend from it's initial survey orbit into the first high-altitude mapping orbit. The North Pole is located at bottom center, and a distinctive cluster of three craters (nicknamed 'The Snowman') is found at bottom right. The grooves running across the surface are faults created by the Veneneia impact. This collision nearly broke Vesta apart, and left the asteroid with a distinctive out-of-round shape.

Curiosity looking out over western Glen Torridon, a large east-west trending bedrock valley formed along the northern flanks of Mt. Sharp. This valley hosts strong orbital detections of clay, and was the target of the mission's geologic explorations. This image was taken from Central Butte, a large mound located near the southern edge of Glen Torridon. The low rise of Vera Rubin Ridge (which begins to fade out to the west of Curiosity's location) is visible as the chain of small hills at right. The gently sloping hill in the midground at left is a portion of the Greenhaugh Pediment, which was formed by rocks deposited at the mouth of Gediz Vallis, a channel that was carved into Mt. Sharp's flanks later in the crater's history. Central Butte is an isolated erosional remnant of these rocks. This image was taken on Sol 2577 (November 5, 2019).
