The Horsehead Nebula in Infrared from Hubble
21.09.2022

While drifting through the cosmos, a magnificent interstellar dust cloud became sculpted by stellar winds and radiation to assume a recognizable shape. Fittingly named the Horsehead Nebula, it is embedded in the vast and complex Orion Nebula (M42).

APOD: 2023 March 12 Б Saturns Hyperion: A Moon with Odd Craters
12.03.2023

What lies at the bottom of Hyperion's strange craters? To help find out, the robot Cassini spacecraft that once orbited Saturn swooped past the sponge-textured moon and took images of unprecedented detail.

APOD: 2024 June 4 Б Comet Pons Brooks Develops Opposing Tails
4.06.2024

Why does Comet Pons-Brooks now have tails pointing in opposite directions? The most spectacular tail is the blue-glowing ion tail that is visible flowing down the image. The ion tail is pushed directly out from the Sun by the solar wind. On the upper right is the glowing central coma of Comet 12P/PonsБBrooks.

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.

X-Ray Pleiades
18.03.1997

The Pleiades star cluster is one of the jewels of the northern sky. To the unaided eye it appears as a lovely and tantalizing grouping of stars in the constellation of Taurus, while telescopic views reveal cluster stars surrounded by delicate blue wisps of dust-reflected starlight.

Stars Without Galaxies
15.02.1998

Galaxies are made up of stars, but are all stars found within galaxies? Using the Hubble Space Telescope, researchers exploring the Virgo Cluster of galaxies have now found about 600 red giant stars adrift in intergalactic space. Above is an artist's vision of the sky from a hypothetical planet of such a lonely sun.

An Apollo 15 Panorama
13.01.2004

The Apollo 15 mission to Earth's Moon was dedicated to better understanding the surface of the moon by exploring mountains, valleys, maria, and highlands. Astronauts David Scott and James Irwin spent nearly three days on the Moon while Alfred Worden orbited above in the Command Module.

X Ray Saturn
12.03.2004

Above, the ringed planet Saturn shines in x-rays. Otherwise beyond the range of human vision, the eerie x-ray view was created by overlaying a computer generated outline of the gas giant's disk and ring system on a false-color picture of smoothed, reconstructed x-ray data from the orbiting Chandra Observatory.

Minotaur Dawn
21.12.2006

Last Saturday, some colorful dawn skies along the US east coast featured the Moon and a Minotaur rocket climbing into low Earth orbit. The 7AM launch of the four stage Air Force Minotaur I rocket took place at NASA's Wallops Flight Facility on Virginia's eastern shore.

Saturns Rings from the Other Side
9.06.2008

What do Saturn's rings look like from the other side? From Earth, we usually see Saturn's rings from the same side of the ring plane that the Sun illuminates them. Geometrically...
