APOD: 2023 January 16 Б Moon Enhanced
16.01.2023

Our Moon doesn't really look like this. Earth's Moon, Luna, doesn't naturally show this rich texture, and its colors are more subtle. But this digital creation is based on reality. The featured image is a composite of multiple images and enhanced to bring up real surface features.

Titan Through the Haze
26.10.2004

What are these surface features on Titan? This planet-sized moon of Saturn had much of its south polar surface imaged during an initial flyby by the Saturn-orbiting Cassini spacecraft back in early July.

Saturn's Hyperion: A Moon with Odd Craters
28.01.2007

What lies at the bottom of Hyperion's strange craters? Nobody knows. To help find out, the robot Cassini spacecraft now orbiting Saturn swooped past the sponge-textured moon in late 2005 and took an image of unprecedented detail.

Infrared Saturn
22.02.2003

This delightfully detailed false-color image of Saturn was taken in January 1998 by the orbiting Hubble Space Telescope. The picture is a combination of three images from Hubble's NICMOS instrument and shows the lovely ringed planet in reflected infrared sunlight.

Shadow Set
27.01.2005

A nearly full Moon and planet Earth's shadow set together in this scene captured Monday from snowy Mt. Jelm, home of the Wyoming Infrared Observatory. For early morning risers (and late...

Conjunction Colours
23.08.2012

During the past week, nightfall on planet Earth has featured Mars, Saturn, and Spica in a lovely conjunction near the western horizon. Still forming the corners of a distinctive celestial triangle after sunset...

Saturns Hyperion: A Moon with Odd Craters
30.06.2013

What lies at the bottom of Hyperion's strange craters? Nobody's sure. To help find out, the robot Cassini spacecraft now orbiting Saturn swooped past the sponge-textured moon in 2005 and 2010 and took images of unprecedented detail.

Mars Perseverance Sol 3
26.02.2021

Stitched together on planet Earth, 142 separate images make up this 360 degree panorama from the floor of Jezero Crater on Mars. The high-resolution color images were taken by the Perseverance rover's zoomable Mastcam-Z during mission sol 3, also known as February 21, 2021.

Red Sprite Lightning with Aurora
22.05.2013

What's that in the sky? It is a rarely seen form of lightning confirmed only about 25 years ago: a red sprite. Recent research has shown that following a powerful positive cloud-to-ground lightning...

Two Hours Before Neptune
14.02.2015

Two hours before closest approach to Neptune in 1989, the Voyager 2 robot spacecraft snapped this picture. Clearly visible for the first time were long light-colored cirrus-type clouds floating high in Neptune's atmosphere. Shadows of these clouds can even be seen on lower cloud decks.
