Northern Pluto
18.08.2023

Gaze across the frozen canyons of northern Pluto in this contrast enhanced color scene. The image data used to construct it was acquired in July 2015 by the New Horizons spacecraft as it made the first reconnaissance flight through the remote Pluto system six billion kilometers from the Sun.

Coronal Holes on the Sun
18.03.2003

The ominous, dark shapes haunting the left side of the Sun are coronal holes -- low density regions extending above the surface where the solar magnetic field opens freely into interplanetary space. Studied extensively from...

The Mineral Moon
29.08.2003

Even if the Moon really were made of green cheese it probably wouldn't look this bizarre. Still, this mosaic of 53 images was recorded by the Jupiter-bound Galileo spacecraft as it passed near our own large natural satellite in 1992.

Earths Recent Climate Spiral
22.08.2022

Is our Earth warming? Compared to the past 250 million years, the Earth is currently enduring a relative cold spell, possibly about four degrees Celsius below average. Over the past 120 years, though, data indicate that the average global temperature of the Earth has increased by nearly one degree Celsius.

Neutron Mars
4.09.2004

Looking for water on Mars, researchers using detectors on board the orbiting Mars Odyssey spacecraft have created this false-color global map of energetic neutrons from the otherwise Red Planet. What do neutrons have to do with water?

APOD: 2026 January 18 Б Jupiter from the Webb Space Telescope
18.01.2026

This infrared view of Jupiter by Webb is illuminating. High-resolution infrared images of Jupiter from the James Webb Space Telescope (Webb) reveal, for example, differences between high-floating bright clouds -- including the Great Red Spot -- and low-lying dark clouds.

Behind Saturn
1.08.2016

What's behind Saturn? The first answer is the camera itself, perched on the Cassini spacecraft currently orbiting behind the planet with the most grand ring system in our Solar System. The unusual perspective...

APOD: 2024 May 12 Б Red Aurora over Poland
12.05.2024

Northern lights don't usually reach this far south. Magnetic chaos in the Sun's huge Active Region 3664, however, produced a surface explosion that sent a burst of electrons, protons, and more massive, charged nuclei into the Solar System.

Neutrino Associated with Distant Blazar Jet
16.07.2018

With equipment frozen deep into ice beneath Earth's South Pole, humanity appears to have discovered a neutrino from far across the universe. If confirmed, this would mark the first clear detection of cosmologically-distant...

Shackleton from ShadowCam
5.05.2023

Shackleton crater lies at the lunar south pole. Peaks along the 21 kilometer diameter are in sunlight, but Shackleton's floor is in dark permanent shadow. Still, this image of the shadowed rim wall...
