Valles Marineris on Mars is the largest canyon in the Solar System.

4,000 km (2,500 mi) long

200 km (120 mi) wide

and up to 7 km (23,000 ft) deep

This picture shows Valles Marineris, seen at an angle of 45 degrees to the surface in near-true colour and with four times vertical exaggeration. The image covers an area of 630,000 sq km with a ground resolution of 100 m per pixel.

Less than 20 minutes after Cassini's close approach to Titan on March 31, 2005, its cameras captured this view of Saturn through Titan's upper atmosphere. The northern part of Saturn's disk can be seen at the upper left; dark horizontal lines are shadows cast upon Saturn by its rings. Below this level, Titan's atmosphere is thick enough to obscure Saturn.

The diffuse bright regions of the image (below Saturn and at the right) are light being scattered by haze in the upper reaches of Titan's atmosphere.

This image is scientifically useful because it shows properties both of how Titan's haze transmits light (from the attenuation of light from Saturn) and of how the haze reflects light (from its brightness next to Saturn).

The image was taken in visible light with the Cassini spacecraft wide-angle camera at a distance of 7,980 kilometers (4,960 miles) from Titan, when Saturn was about 1.3 million kilometers (808,000 miles) away. Image scale is about 320 meters (1,050 feet) per pixel on Titan.

It is over 100 meters deep and may be up to 300 meters deep in places. It covers an area larger than all of the Great Lakes combined and contains 80% of all the liquid on Titan's surface.

Astrophotographer KAGAYA wrote on his post:

>The moon, on the verge of spilling over, is sinking into the horizon. From the sea cave of the island, a slender moon peeks out—a rare chance that happens only a few times a year, and I was fortunate to capture this fleeting scene.

In this onboard video from the Soyuz spacecraft taken on March 27, 2015, one can see the complete approach of the spacecraft toward the International Space Station.

The object visible in rotation is the antenna of the Kurs automatic docking system.

Before reentering Earth’s atmosphere at the end of Artemis II, the Orion spacecraft’s crew module — carrying the astronauts — separated from the service module that provided propulsion and power throughout the mission.

The featured image shows all 110 objects in the catalog at uniform scale -- the same magnification.

The deep sky objects in the catalog include a supernova remnant (the Crab Nebula, M1), other galaxies (such as Andromeda, M31), nebulae (e.g. the Orion Nebula, M42, a star-forming region) and stellar clusters (such as the Pleiades, M45, a bright young open cluster).

A slice through the COSMOS-Web cosmic-web map, showing galaxies across nearly 14 billion years of cosmic history. The vertex on the left marks the present day; moving outward, each galaxy is placed at its distance in cosmic time, reaching back to when the universe was less than a billion years old.

Bright yellow regions show the dense clusters and filaments of the cosmic web, while dark regions mark the near-empty voids in between.
