Venus, Zodiacal Light, and the Galactic Center
18.10.2013

The bulging center of our Milky Way Galaxy rests on a pillar of light in this luminous skyscape. Recorded on September 22nd in dark South African skies, rivers of dust seem to flow downward from the galactic center towards Antares, yellowish alpha star of the constellation Scorpius, near the top of the scene.

Earth at Night
12.02.2022

This is what the Earth looks like at night. Can you find your favorite country or city? Surprisingly, city lights make this task quite possible. Human-made lights highlight particularly developed or populated areas of the Earth's surface, including the seaboards of Europe, the eastern United States, and Japan.

An Unusual Globule in IC 1396
11.12.2022

Is there a monster in IC 1396? Known to some as the Elephant's Trunk Nebula, parts of gas and dust clouds of this star formation region may appear to take on foreboding forms, some nearly human. The only real monster here, however, is a bright young star too far from Earth to hurt us.

Alnitak, Alnilam, Mintaka
19.11.2025

Alnitak, Alnilam, and Mintaka are the bright bluish stars from east to west (upper right to lower left) along the diagonal in this cosmic vista. Otherwise known as the Belt of Orion, these three blue supergiant stars are hotter and much more massive than the Sun.

A Continuous Eruption on Jupiters Moon Io
6.06.2000

A volcano on Jupiter's moon Io has been photographed recently during an ongoing eruption. Hot glowing lava is visible on the left on this representative-color image. A glowing landscape of plateaus and valleys covered in sulfur and silicate rock surrounds the active volcano.

Io in True Color
15.07.2001

The strangest moon in the Solar System is bright yellow. This picture, showing Io's true colors, was taken in 1999 July by the Galileo spacecraft currently orbiting Jupiter. Io's colors derive from sulfur and molten silicate rock. The unusual surface of Io is kept very young by its system of active volcanoes.

Leaving the International Space Station
16.12.2001

It was time to go home. During their eight days aboard the Earth-orbiting International Space Station (ISS), ESA Flight Engineer Claudie Haigner, Russian Commander Victor Afanasyev, and Russian Flight Engineer Konstantin Kozeev had completed several experiments and successfully delivered a new lifeboat.

Jupiter, Io, and Shadow
6.12.2002

Pictured above is the innermost of Jupiter's Galilean satellites, Io, superposed in front of the gas giant planet. To the left of Io is a dark spot that is Io's own shadow. A solar eclipse would be seen from within the shadow spot on Jupiter.

Starbirth in NGC 1808
22.03.1998

The center of galaxy NGC 1808 is bursting with new stars, but why? Being a barred spiral galaxy makes NGC 1808 somewhat similar to our own Milky Way Galaxy. But the disk of NGC 1808 (inset) is quite warped, and its center is unusually bright and blue.

Io in True Color
2.05.2004

The strangest moon in the Solar System is bright yellow. This picture, showing Io's true colors, was taken in 1999 July by the Galileo spacecraft that orbited Jupiter from 1995 to 2003. Io's colors derive from sulfur and molten silicate rock.
